get the engine running first, clean and grease everything, then change all fluids that are bad, and try to keep the machine dry. I had to replace starter solenoid, 1 track spring, a track tension cylinder, and convert from generator to 24 volt alternator. If you run into any issues, let me know and I will try to help unless you have deep pockets and just want send it off to cat dealer.
@@scottmerlo380 No deep pockets here. Thanks for those suggestions. I talked to the 86 year old owner last night and learned that the dozer was last run just 3 months ago. The engine was recently gone through with $5,900 in new parts used in the overhaul. I apparently I got a good deal on this old D4D.
@Charles Foster order a parts manual off ebay or bother cat dealer and get new filters and oil if not changed recently. I will try and do a walk around of mine in a week or 2. Mine doesn't like cold weather so I put a port after air filter where I can preheat with a torch.
Been using it since last year, no blowby or oil consumption. It is no showpiece, but it gets stuff done that would take my tractors, excavator, or skid loader forever.
