Hi
I,m relatively new here but I bought a D2 that drives and pushes dirt but the pony motor needs lots of work. I am a pro mechanic so I can handle the proper repairs. My problem is finding the best parts source for one stop shopping. I,ve seen the parts sticky, and even called a few suppliers, but not finding the best place. I need .020 undersized main bearings, standard rod shells, an oversize (any) piston, rings, all gaskets and seals. Do I always need part numbers before shopping? I don't have the parts book yet.
I,ll keep looking but I,m sure someone can give me some professional counciling.
Great site here, thank you.

You need to part numbers plus usually Model/Serial numbers to determine any upgrades that supercede the numbers you may have.

One stop shopping you you say? The dealer should have it all.

Yeah, I,m finding that out, but I was under the impression that Hastings, Cleavite, Olsens Gaskets and others could supply things at lower prices. I,m surprised at what Cat has in stock, and the prices are,nt too bad on some things, but others they are pretty high. The main and rod bearings especially. Also, they do not have the oversize piston so I might go with a sleeve because my standard pistons are in good shape.
I,ve read here stories of guys who make the main bearings out of aluminum, so I probably will follow that path.
Does anyone have the part number for the Hasting rings that fit? If I sleeve I,ll need two sets of standards.

Thank you to this site for all the info.

Pony Gaskets from Cat are quite reasonable. I inquired about a D2 main engine gasket set from Olsens Gaskets a couple years ago and they wanted over $1600 for all of the D2 Diesel gaskets from what I remember.

Hello
Where do you live.
I ended up with quite a few NOS pony parts.
Perhaps I can help if you can't find needed parts local to you.
I just need part numbers to check what I have.
I only have about 1/3 of my parts home now but am bringing more in the next week or so.
Regards Chris

I've decided to go with the "make your own" main bearings after reading several archived posts on this site, but I ve never seen a good bearing. Mine are trashed. I can figure out the ID and OD, but I'm not sure what the bearing flanges look like and what their stock demensions would be. Do both bearings have a thrust flange, or just the flywheel end? Would someone have pictures, drawings or demensions for the flanges? (if they had them)
Thanks

New pistons and rings are available here in Australia for that pony motor from "J.P. Pistons" in Adelaide, South Australia, they cost around $US130 per barrel for up to 80 thou oversize piston, plus rings, gudgeon pin and circlips to suit. Once you bore your cylinder you tell them what size pistons you need and they machine everything to fit, including the new rings, I've bought a set and found them good quality, if you need help shipping I'm sure someone here in Oz can help though Australia Post usually surprise me with their overseas airmail prices, they are nothing like the excellent USPS prices:jaw:.

I buy a lot of parts from Florin Tractor Parts in Sacramento, they are good to deal with and prices are reasonable, plus they have a lot of aftermarket parts at better prices than the genuine bits, if you phone or email them just make sure you quote your main engine serial number so they are working from the right parts number book. Good luck.
regards
Mike

The main bearing are not flanged, they do have an oil groove and holes, You need to get a manual & read the installation procedure.

Thanks Stephen!

Are you saying the main bearings are straight on the outside diameter with no flange? I do have the shop manual, but my flywheel side bearing definitely has a machined flange about 3/16 wide that acts like a thrust surface for the crank. The PTO side bearings have what appears to be a worn out flange, but it might be extruded aluminum from damage. I know that the PTO washer is used as a thrust control but that side of my engine is all messed up from a prior repair in 1963. Maybe someone already tried the "make your own" route and changed the way it works.
If both bearings normaly have a straight OD that changes my understand a bit. That's why I,d like a drawing or photo. I don't recall seeing a definitive image in the shop manual, but you have my couriosity up now.
Thanks again

There is a place in California that makes pistons, I found them while GOOGLING for piston rings last month.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
