There seems to be two motors to choose from , xxxx-cr and xxxx-8r along with several D21P-6 , r,c,ac and bc , difference in the dozers seems to be the blades . Going by the last link the thermostat is used in a lot of different applications .New to the group and purchased a pair of d21p-6’s. Replacing all fluids etc. I popped thermostat off one looking for part numbers to no avail. Anyone have a link or part # offhand? Ive tried google but nothing that specifically says for D21z
Awesome, thank you! Looking forward to getting some good use out of these. Do they typically run warm? Both of these I have were running on the hot side of the green mechanical gauge.There seems to be two motors to choose from , xxxx-cr and xxxx-8r along with several D21P-6 , r,c,ac and bc , difference in the dozers seems to be the blades .

They will have an operating range , should be able to find that in a workshop manual . A hand held infrared thermometer's are cheap and will show any problems with your radiator . There should be a good difference between the temp at the top tank and bottom tank of the radiator . Funny thing with an infrared temp thermometer they need to be pointed at non reflective area's otherwise they give a lower reading by quite a bit .Awesome, thank you!

your shift cables haven't gone slack have theyGood morning. I’ve been a long time lurker but haven’t posted much at all.
I have a Komatsu D20a (sn#45119) that’s a mid to late 80’s model. In the last month or so , the steering and ability to back up had gone away with one exception. It does ok when the dozer is pointed up hill and the fluid is to the back of the machine . If it’s on an incline it steers good but not great. The clutch oil is fresh. It has IW32 in it. Everything I’ve read says that’s the equivalent to SAE 10wt. Also, I pulled the strainer and it had some junk on it but not terrible. I’m leaning towards the clutch pump (haven’t tested) , since that’s the piece of equipment the steering and drive clutch share . Anything that I’m missing? All fluids and filters are fresh within the last few months. I do notice that when I’m on flat ground I can press the clutch foot pedal and that side track will relax . I’ve adjusted brakes, linkages, etc.
If your getting a loud squeal most likely its coming from your final drive, I pulled my left side drive off and the small bearing that is on the case side was gone totally nothing inside the drive there were very vew pieces of it left, the pinion had some chips out of the the drive teeth so i replaced it along with the bearing, i had no idea that it had failed till i heard that very loud squeal, currently replacing small bearing again due to that big nut that holds on to the flange some how came off and and i was loosing power to that track the splines were just skiping and not grabing under a load, i should have replaced both pinion and flange but its about $750 for both pieces so did a little grinder work fabed a cage to hold the nut so it should not come loose at all but that squeal is sure sign that parts of that bearing have broke and just get ground up in that bull gear and I guess when you go in reverse the pieces you can see grind on the inside bottom of the cases ,,Not specifically. Where would be the best place to do that?
