I'm just wrapping up servicing my old direct drive D4 that I bought last year. It was a little damp underneath when I bought it so I removed the skid plates to see what was going on. I replaced a few gaskets, installed all new filters, fluids and cleaned the screens. I accidently knocked a small piece of cardboard into the flywheel clutch housing after I removed the starter. I don't have access to an O-scope to see where it went and spent over an hour hoping to snag it with a piece of wire, all in vain. The nice thing about this tractor is that it takes 30W oil for everything: engine, flywheel clutch housing, tranny, finals, etc.

One of the favourite machine

I don’t know how you don’t have way more subscribers

Looks like a big job!

That's exactly what I'm doing to my D5 direct drive.

An old man taught me- turn a 5 gallon bucket sideways or upside down when trying to pour oil like that- it allows the air in and flows way better and faster with less mess and splash etc.

Love the old iron. Next time you have to crawl under for wrench turning drive it up on some 2x lumber. May help you have better clearance underneath.

I see a big overhaul in the future

by seeing the dirt above the belly pan ,next time you go under it would be a great idear to drop the belly pan

Very Good , I have a D6C its a Little Different

Guess I am claustrophobic but I drive my crawler up on some 4 x 6 or 6 x 6 timbers to provide a little more crawl space. Especially when getting under the transmission or rear end.

Does it have a inter cooler if not then it could have a busted block or head gasket or crack head or a bad piston sleeve hope u can get her right cause they ain't nothing like that old school stuff just found your channel going to watch the rest of your vids
