1991 520h snaped rear drive axle

Recommended Posts

Dave 520h

My 520h has a kwik way loader which works nice.  I just lended it to a friend and he brought it back with a snapped rear axle.  If someone could point me to one or both I'd appreciate it.

Curious if that tractor has dual rear tires on it?

Yup, had the same thing happen on mine. Broke right at the key way (weakest part). I don't run duals on it any more even though I liked the stability.

So at least your friend might not be to blame for this. Probably just went over some uneven ground with it and the leverage of that added length was too much. Could've been cracked already and finally hit the last straw. OR, he's just hard on equipment but it's still caused by the added leverage.

Father-in-law broke one on his 91 520H blading snow. He used to open all the driveways in his neighborhood for free. His neighbors constantly brought over pies, cakes, and other deserts for his sweet tooth and as a thanks for his good deeds.   :)

That's great. I will email you tonight. Thanks

 

You can see it was already cracked 1/2 way.  There is a dull half and a clean break. No telling how long it was like that.

Wallfish. Is that a 520 with a backhoe? That's badass.  Not stock equipment?

 It's a 416-8 --- FEL is factory and I built the backhoe using plans from PF Engineering.

here's some more pics of it in his gallery

Found my LR hub loose on my 520H.  Pulled the hub and found the axle cracked.  I have a Quickway loader on it and single wheels, weight box and chains.  I guess we will have to ease up on these things.  Not looking forward to opening the case to replace the axle, if I can find one.

There was a guy that responded to me on this forum that may have it.  daveoman@windstream.net  I know he has the long axle on the "passenger" side.  It took me about 3 hours to remove mine.  I will get the part tomorrow so I'm amped to get it back together.  The nice thing is that you don't have to remove the entire rear end.  Just take off the bolts and open the rear.   The drive wheel is the short axle and its 10 1/8" long.  The long shaft is 13 1/8".  Good luck!

One more thing.  If you leave the bucket on and weight it enough it lifts the back end and its real easy to work on.  You can block the back end after its up.  Just do it safe.

Now you tell me, I pulled the loader off because of the way it goes over the axle.  I can see now that there is room to move the housing out and back.  Unless I can find another axle, I can buy the long one from the same guy and cut it down if it's not hardened.

 

A few questions, if you don't mind.  Did the hydraulic pipes give you any grief?  I have a 97 and they are in front of the housing at the top.  Do you need to remove the brake drum, or does it stay with the housing?  Thanks.

I was able to get the cover off without removing the 2 lines that go to the oil filter.  I did take the brakes off though, you will need a wheel puller for the brake drum.  You should be able to cut the long axle but u will need to grind a slot for the 2 screws that lock it to the hub.  I have an air powered cutting wheel from Harbor Freight.  That will cut that axle.  Its cheap.  I paid $77 for the axle from that dude.  Anything else let me know.  I am happy to help if I can.

Dave, thanks for the advice.  My hydraulic lines run at the top with the wires, so I might have to loosen them at both ends.  I didn't want to disturb them if I didn't have to, they are jammed in there tight.

 

I have a tool & die shop so machining wouldn't be a problem so long as the axles are not too hard.  Anyway, a pair of axles were just listed on eBay and I snatched them up immediately.  If you need any machine shop work, holler.

 

Thanks again :thanks:

I have posted this on here a couple of times. This was passed on to me from a Wheel Horse factory rep. Wheel Horse recommend putting duals on because of the instability issue when using a loader. Then they found out that the extra leverage the duals were putting on the axels were snapping them. To correct that they came out with a HD Axel set to be installed to help prevent axel snapping and key way movement. This in turn started causing the transmission cases to start cracking. This all came about because they were trying to over come the lack of people not using common sence when having the loader raised in the air. 

The old saying goes you can't fix stupid. But I guess they look at it from a legal liability issue its better to break axel or snap a transmission in order to keep the company from being sued by someone that can't comprehend center of gravity (top heavy). Sorry for your broken axel, you are just one of the many victims of the legal dept's authority over the engineering dept.

Thanks for the information.  I am going to stick with the dual tires.  I deflated the outer ones a bit, so I wont stress the axle unnecessarily.  Even with the bucket low on a grade it feels safer.  Plus it looks good!!  ha.  I will be on the lookout for more axles.  My machine is a '91 and the loader was factory installed.  From what I was told, this had not happened before my encounter so if I'm good for another 25 years I'd be happy.  Where can a hold one of those HD axles?

I doubt  that Toro has them anymore. You can check at a dealer. Sometimes Toro stills has old stock on thier warehouse shelves. I don't know if they were for the 8 speeds or just the hydros. I think they were introduced back in the late 70's. Not sure how long they were offered. My local dealer told me he had never sold any, and he was a old dealer.

      So I was out mowing the other day with my 310-8 and somehow snagged my wheel in a hole in the yard. Anyways I pretty much destroyed my ball joints. I've since replaced the tie rod with junkyard parts but I was wondering if anyone's found a heavy duty aftermarket replacement for the tie rod assembly.
       
      Like would generic adjustable go-kart tie rods do the trick?

      Hi everyone,

      I bought a wheel-horse c-160 a while back, and did some work with it.
      One day the rear axle housing broke:


      I was thinking about changing the part or soldering the broken pieces.
      Does anyone know where to order this part? Or has any idea of the potential cost of a soldering job?
      Thank you in advance!

      This is the story of how I removed a broken head bolt from the K181 in my 854. I am posting this up as it may help some of you in the future with your own issues.  Use it at your own discretion, it may not be the best way of approaching this situation, but it worked well for me.
       
      A little backstory on the situation, I purchased an 854 before last winter intending to use it as my worker in the garden in the spring. Unfortunately that didn’t play out the way I had anticipated. The motor would run for 10 minutes or so and then seemingly shut off like you turned the ignition off. 
       
      Mind you the only motors I have ever worked on have been Cummins diesels. Never any small engines or gas motors for that fact so this was a new adventure for me.
       
      I originally chocked this up to being a vapor lock issue caused by the fuel line heating up and boiling causing a lack of fuel in the pump/carb.

      After installing a longer fuel line to move it farther from the exhaust this did not solve the problem. I moved on to the fuel pump. Upon removal of the fuel pump I found a decent amount of corrosion, enough to significantly reduce the volume coming from the output. A short disassembly and cleaning later and I was shooting gas several feet from the pump while cranking. The issue persisted.
      Moving on to the carb, I found the carb decently clean, but disassembled and cleaned it just to be sure. With the carb reinstalled and adjusted the issue persisted.

      With my issue still persisting I removed the head to check for any issues I may see internally with a quick inspection. I found a piston that is obviously loose in the bore, which I expected with the blue haze this motor has while running. However I do not think that is causing the 10 minute run time, I since believe that the issue is electrical, likely coil related.
      But on to the real meat of this, the broken head bolt.  While removing the head I broke the bolt closest to the exhaust port.  This seems to be, from some of the other posts I have read here, quite the problem area.
       
      Luckily the head bolt broke approx. ½” or so above the deck of the block so I thought I could get it out.
       

       
      Several attempts at removing it were tried:
      -          Apply heat with a MAP gas torch until bolt was red hot, followed by plenty of penetrating oil. (Before each attempt)
      -          Vice Grips (Simply rounded the bolt)
      -          Cut slot in top of bolt, use impact screw driver (Remaining bolt broke off on either side of the slot)
      -          Welded a Nut on ( Broke 3 nuts off)
       
      I finally stopped these approaches when the bolt was approx.  .125” tall for fear of damaging the deck of the block.
       

       
      At this point I resigned; it was time for a professional to work on the motor. I would have it bored and have them drill the bolt at the same time. So there it sat taking up space in the garage for several months, a monument to my failure while I saved some spare money to have it fixed. While my plow, disc, and cultivator gathered dust behind the shed and my garden mockingly grew up in weeds.
      While at work one day the thought hit me as I watched someone use a drill bushing on a tool to transfer a hole from a mating part. Maybe I should try another attempt after all that motor runs strong when it’s running so I could live with the blue haze from the loose rings. I really don’t think the issue that’s causing the motor to stop is internal since it runs so good when it is running.

      So I went home and measured the size of the clearance hole in the head, and armed with that information I had a friend make me some homemade drill bushings.
       
      Using some O1 rod we turned three bushings with .340” OD’s and 5/32”, ¼”, and 17/64” ID’s.
       

       
       

       
      I purchased a set of left hand drill bits at Harbor Freight and a center drill. I also purchased a 17/64” left hand bit from MSC. (MSC PN 81127177) and a 5/16-18 plug tap (MSC 77430080).
       

       
       
      Here are all the tools I used. 
       

       
      The first step was to install the head back on the motor to use as a guide block. In hindsight I would have cut a 5/16 counter bore on the back side of my drill bushing to fit over the broken stub of the bolt and be sure I was lining up perfectly. However hindsight is 20/20 and I will do that next time. If your bolt is broken below the surface of the deck you could thread the end of a shaft that fits in your head and use that as an alignment dowel as well so there are several viable approaches.
       
      With the head loosely bolted down I carefully adjusted it until the gap around the bolt looked even and then cinched the head down tight. This is the last time the head will come off until the bolt is removed and I was ready to tap. After the head was situated and tight I installed the .250” ID drill bushing in the head and tapped it down gently until it contacted the bolt. A healthy shot of oil was shot in the bushing, I would recommend tap-matic or another cutting fluid but I had WD-40 at hand so I used that. The compressed propellant also works well to blow chips out if you do not have access to compressed air.
       


      Using the #3 center drill, which conveniently has a shank diameter of ¼” and the ¼” bushing I drilled a starting hole to keep subsequent drills on track. This only needs to be .050” deep or so. I quickly found that the top of my bolt was very hard.
       

       
      Since this was my first time using harbor freight drills, I was unsure about using the 5/32” drill, and there was already a .250” bushing in the head so I skipped that step and started drilling with the ¼” drill.

      I would drill ¼” deep or so slowly with moderate pressure, I found after the first ¼” or so the drilling became much easier. I must have quenched the bolt with the penetrating oil with my original attempts at removing it with heat and penetrating oil.
       
      I would periodically check my depth by marking the drill with my thumbnail and then putting the drill bit down an open hole in the head until I was sure I was deep enough. Although, the hole would if drilled too deep end up in the exhaust opening, which should not harm anything, but wouldn’t be ideal. I expected that the drill would “fall” through the dead space at the bottom of the hole, but I never experienced that even after drilling deeper than I would have ever expected.  (The head bolts are only 1-1/2” long and that includes going through the head)
       
      I was impressed with the Harbor Freight drill, and it made short work of the drilling, drilling 1 ½” or so deep in short time.
       


      At this point the bushing had ridden up out of the hole with the chips built up under it and was easily removed. If this happens while drilling you will want to remove it, and blow out the hole and then replace the bushing. This ensures your drill is tracking straight at all times.  I blew out the hole well, and then replaced the ¼” bushing with the 17/64” drill bushing. 
       
      The reason for the 17/64” drill bushing is that it is quite close to the minor diameter of a 5/16-18” drill bit. Think of the minor diameter as the size of a bolt if you removed only the threads, the solid portion left inside is the minor diameter. This means when I drill out with this size, if I am centered well, only the threads should be left in the block. Depending on how stuck the fastener is the left hand bit may even catch some of the threads and spin them out, otherwise all of this work could be performed with cheaper and easier to obtain right hand standard drills.
       
      As with the previous size the 17/64” drilling went well, and it even pulled out the first few threads. I proceeded in much the same way only drilling ¼” or so then stopping to blow out the hole, clean the drill bit, apply more lube, and push the bushing back in the head, while checking depth against another hole in the block.
      A short time later I had a drilled out hole, and it was time to remove the head again after thoroughly cleaning the area to prevent metal chips from migrating to the cylinder bore.
       

       

       
      With the head removed I was relieved to see that my hole appeared to be well centered on the bolt and I moved on to the tapping operation.
       


      Much to my delight it threaded almost as easy as the tap turned in an already tapped hole, simply pushing the remaining threads out of the hole. I stopped every few threads and backed up to break any chip that was forming, as well as stopping every ½” or so to blow out any chips. Again being careful to not introduce them to the valves (Motor turned to be on the ignition stroke so both valves are closed) or the cylinder bore.
       

       

       
      Job successfully completed!
       
       
       
      I purchased some new bolts today to reinstall the head, and will be picking up some anti seize as well to thoroughly lube the hole up.

      I am not a member yet, but when I have some extra cash I will be, and at that point I will upload some of the multitude of pictures I took during this process if anyone is interested in those.
       

      After that it’s on to seeing if a new coil, condenser, spark plug wire, and spark plug fixes this thing for good!

      I have a 1976 C-120, 8 speed, that has had a bad rear axle key way for about 35 years.The plastic steel we put in to keep things together finally gave up the ghost last year. I tried some welding but that hasn't held up either. My question is will the rear axles from a C-81 8 speed fit in my transmission? According to the parts lists I found on this site, both trans have 1 1/8" axles and 8 pinion diffs, but the axle part numbers are different.  Any help is greatly appreciated. I'm brand new to the site and think its great!
