D2 Diesel Rebuild Kits??

There is no "rebuild kit" for a D2. If it is "blowing by" out the exhaust, then take the valve cover off and adjust the valves to the proper spec. Change the filter and oil. Actually if you have never done it, then change all the vital fluids and filters besidess lubricating and adjusting everything.
Then take it out somewhere, hook a set of plows on it or disk, work it up to operating temperature and keep it loaded for a few hours. I suspect that slobbering out the exhaust will go away.
You didn't mention excessive blowby out the crankcase breather?

drujinin, thanks for the reply! Didn't think about adjusting the valves. I think someone said always start simple first. 😊 Cat has good power, so I think compression is good. Will definitely change all fluids (started with pony oil and working my way through including oil in gear cases). Doesn't seem to be blowing any oil from crank breather (now that I got it unclogged!) Thanks!

Where are you located? Usually idling them cold is what causes them to slobber. There is a wealth of info on D2' that can be found byusing the Search feature.

Have an explicit procedure of how to prevent engine oil consumption
One of the tricks (the CAT)
Is to dismantle the air filter and engine to inhale a special material
We learned from experience the intake manifold to disconnect
Working engine at idle (hot)
Then inject detergent (washing machine powder) into each cylinder
Each piston handful of small hand (2 tablespoons soup)
And everything with the motor running
You can repeat this process a maximum of 3 times (by a margin of at least 10 engine hours)

Waiting for results

Itzik,
Can you clarify the explanation as to why?
Is this a new, not usually mentioned technique to reduce slobbering/oil consumption?
OR
Is it the old, old "Bon-Ami" trick of scuffing the glaze on the cylinder walls to reduce slobbering/oil consumption?
I would not usually mention this technique to a new member because he doesn't state that he has severe slobbering and oil blowing.
Still I think I would make sure the Thermostat is working to keep engine temperature up and changing crankcase oil, then loading the tractor to work it long and hard.

Located in Portland, OR. Have a lot of info around. Just started asking here first. Will definitely adjust valves and see what happens. Will keep you posted. Thanks!

Adjust valves
Replace engine oil filters
Check Thermostat
Of course it must be done

When I take the age of the tractor
The model tractor
And a familiar complaint
I immediately think of the glassy Tzlindr

Recently I met a mechanical engineer
Many years was associated with Caterpillar
And he repeatedly mentioned how they would fix the engines was not a successful Engine Repair👍

Does sound like the old "Bon Ami" procedure to me.

This has its place but is not a cure all and was not recommended for later engines with more advanced rings and sealing surfaces. I hesitate to even post it as it is sure to be abused as a fix for tired out engines.

AFAIK the BonAmi "fix" was only recommended be CAT for a few years, and IIRC it was only meant for the bigger (D7 and up) range of tractors.
I'd stay away from that "cure"

I would also make that D2 work for it's money!

If you're in a cool season, I'd wack a sack over the radiator, and use an offset disc or a 4 furrow plough to put a demand out for those 32 horses that's supposed to be "lurking under the hood" there. Do this for at least 4 - 6 hours.
We had one and after a session in front of an offset disc with a sack over the radiator (really get the temperature up), slobber was gone.
Just be warned: Get yourself a hat and some really OLD clothes, else you'd be covered in more than just a few black oily spots coughed by that working Cat!
