bearing plate frustration

Recommended Posts

tommyg

Ok, this is the second time this thing has broken, so now I'm a bit frustrated. The casting on the bearing plate on my D180 that supports the PTO arm just broke again. Last time the fix was another bearing plate. Now I'm wondering if this is something that will continue to happen and whether or not I need to figure something else out. Anyone else have this issue with their D series and Kohler engine? How did you remedy the problem? I can't just replace bearing plates every time this happens. Anyone have another laying around collecting dust? Does anyone know how this closure plate is removed? Last time I got part way and got stuck. Had to have someone at an engine repair place finish the job. Seems there is a snap ring hiding somewhere that's not very conspicuous. Model # on the engine is K4828.

I am currently replacing my closure plate on my D180 as well.  Once you take the pto clutch off,  there is a seal cap on the front center of the closure plate, pop that off and you will find the another snap ring that you need to remove before the closure plate will come off.  Try not to damage the seal when you remove it,  I found out the hard way that it is 20 bucks for a new one.  The seal is number 15 in the attached picture.

BGH5469, I see one snap ring, (12) but it's on the opposite side of the bearing. How would you get to it? Or is there another snap ring just behind the seal not shown in the picture? Or maybe I'm missing something.

I've suffered this issue with a D-200. From a design perspective, it's not the best to my mind in expecting the lug on the plate casting to support the PTO lever in the way it does. It's an issue that I think is made worse as parts wear e.g. where the pulley / clutch unit pivots on the arms resulting in the need for adjustment that effectively puts more strain on the hook thing that mounts on the bearing plate lug. Just my theory.

Anyway, the D-200 came to me with all the PTO bits in a sack having been removed at some point. The reason turned out to be that the lug was parting company from the plate. Putting all the bits back together I discovered the hook was missing and a PO had obviously attempted to make a little bracket to replace it which gave me an idea given that parts for these tractors are pretty much non-existent here in the UK.

I fabbed a support / reinforcement bracket which was bolted to the main chassis rail. (Those little holes in the closure plate above my bracket are by the PO, a failed attempt I think to stop the fracture lines running any further)

Once it was all painted in red it was hardly noticeable to the casual eye.

It's possible that you could use the original hook with this arrangement but I can't say as I didn't have one. Making the little right angle bracket to take its place was a pain as trying to get the geometry of the whole thing right took more than one attempt and something that I need to revisit when I have time as it could still be better. 

I offer this as a potential 'belt and braces' approach that worked for me. It certainly takes the strain off the bearing plate lug.

The snap ring that holds the plate on is just behind the seal(15)  it is not shown in that diagram.  The snap ring(12) is a monster like 3" in diameter and holds the bearing into plate.  Snap ring (12) does not have to come off till you get the plate off the tractor.

Andy your "belts and braces" idea is great!  I think i am going to add that to my tractor!

OK, that makes sense. In the meantime, Andy, I used some of the same ingenuity you did with a simpler arrangement. I can post some pics this evening, but what I ended up with was a small pieces of 1/4" steel about 3/4" wide and 1 1/2" long. Drilled a hole in each end. To attach it to the engine, I used the existing bolt hole right near the now missing casting lug that attaches the bearing plate to the engine block. Just replaced the bolt with one a little longer. On the other end, I drilled another hole that accommodated the OEM threaded "L" rod used as the pivot point on the PTO arm. The thing is bullet proof and will definitely outlast me! I'll take some pics tonight if anyone else has an issue with this all important lug! Thanks for posting your solution!

Oh, and can you throw a little oil and dirt on your tractor? You're making me look bad.

Glad you've come up with a solution - looking forward to seeing the pics. 
The photos I used were taken about three years ago when the resto was nearing completion - look carefully and you'll see that the new bolts used during reassembly hadn't been painted in yet. The tractor has gained the 'little oil and dirt' you mention since.

Nothing wrong with the rat look though.......this is my other D

 Another old photo - it looks a bit tattier now as PO had wiped it over with oil which I haven't kept up but I have put the correct rear lights on it since.

Andy, here's a pic of what I ended up with. Where the casting broke, it cleared the way for me to attach a piece of bar stock about an inch and a half long. Got a longer bolt to thread into the engine block to secure the bearing plate. Then I used the OEM threaded "L" round stock and welded a washer near the bend. I needed to place a couple spacer washers on next, then secured that with a self locking nut. Turned out pretty good. It really is bomb proof. Sad news was that the very next day, I was cutting the lawn and threw a rod. :-(

Neet work and solution  - I like it! It's what WH should have done in the first place.

Sorry about the rod - that's a ***** but part of life's rich tapestry of challenges with these aging beasts I guess.
My 'shiny' D-200 was laid up for a year till I fixed the dead hydro hopefully you'll get yours on the road again fairly quickly.

      I was looking around on ebay and noticed that hydraulic actuators from John Deere 312, 317, etc models appear to be Identical to a Gt14 or d series lift cylinder. My question is would a new cylinder from ebay be able to replace one that is on a gt14 or d series?
       
      Images below of cylinders to show similaritys.

      My friction disc in gone on my clutch.  I saw the old post about making a new friction disc, so I'm not concerned about that.
      I managed to remove the front clutch plate and double v-belt pulley.  But I can't separate the two.  When I took the assembly off the spiraloc washer popped off on its own.  I HAVE READ THE MANUALS.
      So I should be able to just remove the pulley from the front clutch and continue with step 4.  The v-belt pulley is loose as all hell and flops around like a dead fish.  It seems to be hung up on a ring or bearing race.  
      So my thoughts are grab a BFH or sparky the blue tip wrench.
      Is there an unpublished step 3.5, or some trick?

      Hey all, 
       
      My '74 D180 has a lot of trouble pushing snow.  Weighted tires, but nothing else at this time.  I've found it gets stuck frequently and only one wheel spins.  Do these tractors not have a limited slip/locker arrangement?  How does everyone manage with the infamous one wheel peel?

      Hey all, I need to install a drive belt on my 75 D180 for my snowblower.  I've looked through a bunch of D-series owner's manuals, and none seem to mention replacement procedure.  The PTO pulley is fixed, save for engaging the PTO and there is minimal movement at the snowthrower pulley. There's no idler or tensioner as far as I can tell.  Do I have to remove the PTO pulley?  That seems to be a required service item.
      Same question for my 80 D200 as well really.  
       
      Using the recommended 4L490W belt.
       
      Thanks

      I got a D-180 for $250, and the governor is messed up, the points won't open or close, and I took it apart and was being stupid and messed some stuff up in there, and now I need a new one.
      Where can I get one that's not on eBay for $200?
      I also forgot to say it was a Kohler K482, and I'll throw some pictures of the tractor in as a treat.
