D 200 Engine

Recommended Posts

Hello

 

I have a D 200 and my sons have been cutting the lawn this summer and nerver check th oil and the seized the motor. I freed the motor up and it runs fine until there is a load. I checked the Compression  and I have one dead hole. ;-(   it broke my heart. I have a Mower, tiller, and snow thrower.

 

Any Advise? Should I buy a motor? Or rebuild or scrap?? I liked the machine. But I dont want to dump a ton of money into it if it is questionable. I am not sure if it is a Kohler or Onan??  Any thoughts

 

Thank you

Brian, not much advise but if the engine is original it would be a Kohler 20 HP.  That is a lot of tractor and accessories to let sit if the hydro was strong, it may be worth rebuilding the engine.

The site achto shows is a good source as is ebay.

 

A word of caution here, parts for these big twins - like your K532 - are getting scarce ---- especially CONNECTING RODS!  Its very possible you will need machine shop work what with the engine running low on oil, bore job to clean up the cylinders and regrind the crankshaft, etc. Before you start buying parts determine what work will need to be done . IE: if your crank needs turned then you will need rods and they just may not be available!!

 

In the last couple yrs I have needed a rod for each of my 18 and 20hp twins, I ended up faithfully prowling ebay and after a few weeks was lucky enough to find them used -- and these were in standard size! You may well need undersized..

If it needs rods, I saw a site that makes rods out of aluminum billet stock  I would nose around a bit before making a hasty decision. While the "D"'s are not my favorite's they can do a lot of work for a long time yet.

Thanks :-)

Would you consider Replacing the motor with something else ?? 

 

Send the Motor to a rebuilder?? Brian Miller??

If you are not into keeping it stock consider the Preditor 22hp V twin as a replacement, I have used many of the HF engines

and have had very good luck with them. Their is many parts sources for them now and seem to be very reliable. In our pulling club several

guys have been running them for the last couple of years, and to be honest with you they are kicking our butts at about 1/3 the

 price of a rebuilt/built Kohler.  I think if you go to Brian Millers site the price of a rebuilt opposed twin is going to be in the $14-1500 range.

Harbour Freight and a little fab work . not to complicated, put one of their 13 hp motors on my GT 2500

 and a couple of holes drilled in the base is all I had to do. Plan on replacing it with a 12hp Kohler when 

time permits.

I feel for you. In 1993 western PA had a monster snow (22" in 24 hrs). My dad had a D200 (which I now own). He called my brother in law who lives on the same lane and suggested he fire up the Horse and use it to clear the lane. Jeff took him up on it. Unfortunately my dad forgot to tell him about the engine oil leak. After about three hours of running, clearing a 1/4 mile lane, the engine seized up. Dad had to get a new short block from Kohler and have it installed, not a cheap fix. But I am still using that tractor today. 

If you can find the parts it is very well worth the time to repair this tractor. Do some research, those K532 engines are still out there. Maybe find a tractor bone yard for parts, or the whole engine. 

Might also try this place:   www.isavetractors.com   207-298-9701. They advertise in LAWN & GARDEN TRACTOR magazine and claim to have "everything you need to bring your old engine back to life". They specialize in Kohler K series engine rebuild kits. 

 

Good luck.

      Been wanting to figure out a better way to move dead tractors around - some, just isn't cooperative at being towed - the AC 916H is a great example around here. Since the rear axle is a hydro, it does not disengage fully for some reason and the tires are really shot badly. The 16Auto dug some big holes the last time I tried to move it around, so the idea here is to use the D's 3pt lift and it's size/weight advantage to move other dead tractors. I also wanted a toolbar that could have adapters added for various tasks - such as cultivators, tines, rear blade, ect. I've wanted to build a wrecker for years, just never had the time to do it - this year, I decided I've had enough of my aching back and legs - this needs to get done before I end up in the hospital. Always seems there is no help available when I need it, so now is the time - here is where I'm at as of now...
       

       

       

       

       
      All built from 1/4" thick iron, except the hub mounting plate which 1/2" thick A50 steel. Trailer hub/stub shaft is a 1750lb rated unit. In hindsight, if I ever did it again I'd use a heavier DOM tubing and just turn it to accept bearing races, make the shaft on the lathe and be done with it. Not to mention, I could control the thickness of the assembly a lot better. There are "rear tire carrier builder" parts available out there to do just that with pre-built tubing, the correct bearings and shaft - you just weld it into the square tubing of choice. Still a lot to do - need to make a set of centering springs, locking pins (for toolbar use), tire carrier arms w/tie-down rings, rear blade adapters, ect....
       
      Just thought I'd share a bit - need to some lift testing today, hopefully.

      Looking to get out of the WH business so looking to unload everything as one lot.  Have D160 w/ Onan 16 twin original.  Use it to mow last year so it will run, have not started it this year.  Burns oil but good machine otherwise. Has 48 inch belly mower and snow blower. Other machine is 18 Auto with bar tires, 3 pt hitch and rear PTO, 48 inch Rear finish mower and snow blower.  Current state is that it has motor and hydro pump out because the O rings for hydro pump were leaking so while making that repair I planned to change the Pump shaft out.  Motor and drive are good and I have mowed with this in the past.  Spare parts I have include Most of another Machine that was stripped down so there are spare tires rims, rear end, steering components, I also have 2 o 3 spare hydro pumps, extra hydro line sets (hoses and hard lines), Another 16 horse ONAN that blew a rod currently torn down (may be salvageable, never followed up with it).  I am getting several Allis Chalmers garden tractors passed down to me and since I barely have time for my WH I figure its best to pass these on to another collector and make room for the new fleet coming.  Please reach out to me Via Email and we can exchange contact information and I could send pictures when I make time to take some this week.  Thank you.

      I’m not sure I’m in the right place for this post, but I’ve got a leaky hydro cylinder on my D180. It’s the primary one that lifts the deck, snowblower, etc. I could take a chance on finding one on ebay, but I was wondering if there’s an alternative besides used.

      Fast question ...
       
      Per the IPL for the 6-1141 and 6-1131 54" & 56" blades - how is everyone pinning the rear blade lock arms so they can't unlock the blade ? I've ran into problems with this thing before wanting to unlock itself and drop the blade half off the tractor. It seems when back dragging rough pavement, especially if I back into a snow bank the thing is moving those locks out of position and allowing the frame to drop off. The only reason it stays at least somewhat under the D is the lift arm , but getting it back into position is no fun due to the weight of this thing and especially out in the snow/cold weather. Last time I had to drag the thing back to a clear area so I could wrestle it back into position, lift the frame and lock it again. I did wire them shut for now, but don't trust it and I use it to back drag quite a bit on rough areas I don't want to ram the cutting edge against and risk damaging the rear axle differential or anything else. Mine has been rebuilt with a new cutting edge of 1055HC and the frame is highly beefed up - most of it is now boxed in and the thing has gained nearly 50lbs of steel. It cuts great, almost too good but that random dropping it off is starting to irritate me - need some ideas here...
       
      The smaller 42" and other frames lock from the other direction - so to speak. The brackets are also drilled to accept large hair pin cotters to keep those locks in place - I see no way the bigger blade frame is designed for that, unless I'm missing something ?
