D4d wet flywheel housing?

[hflbz]

Does the 3304 engine in a d4d have a wet flywheel housing? I drained some oil out of the flywheel housing and didn't know if it was supposed to be in there or not thanks. Powershift transmission

Should be dry. The rear main could be leaking. How much did you get out?

 

[hflbz]

About 2 quarts

That is a lot. How long did it take to accumulate? Mine weeps a bit even though it is new but I only get a few drips.

It probably hasn't been drained in 20 years to be honest I know the previous owners didn't do much maintenance

It probably is the rear main seal just wanted to be certain it wasn't a wet flywheel housing

You can do a rear main with the engine in but it is a real pain. Just watch it and keep adding oil unless it gets real bad.

If you do it get the old style seal. Cat has a new one with a sleeve that is meant to be used if there is a wear spot on the crank. They supply that one as standard. I used that one when we rebuilt it and it weeps. I even had the Cat tech come and install it with the special tool just to be sure it was set right. Easier to pay $50 then make a tool. Problem is their tool sets it too deep and it barely catches the lip. Shoulda done it myself or used the old style.
