Oil return from clutch in LA

I am trying to resurrect a LA that has not been started for over 20 years. I changed all the oils and let out the oil from the clutch. The old oils seemed in reasonable condition except from the clutch - it was more like grease.

The clutch is filling with oil and I think the oil return to the sump is blocked. Can anyone help with diagnosis?

I will try flushing the engine and clutch. If I take off the engine inspection plates will I be able to get at the oil return from the engine side ?

I imagine that it the oil return will be behind the flywheel on the clutch side.

Any help will be greatly appreciated.

Thanks

Bob

It is pretty common to find goop, sludge, and water in there. Just drain it and go ahead with whatever you need to do to get the tractor running. Since that compartment is made to hold a quantity of oil separate, it is possible to drain it later without draining the crankcase.

The real crud accumulation is usually on the bottom of the oil pan. Pull the screen, all inspection covers, the drain plug, and prepare for a nasty job. Wear disposable clothes, that old oil and muck will not come out. If the screen is broken, it will need to be SUPER cleaned and silver soldered. I have found crud over 1/2" thick in the pan. The engines don't seem to be harmed by all the junk, guess the settling acted as a filter. Prepare to repeat the cleanout at least once soon after you get it running.

Good luck.

The oil return is a cup on the left side of the engine. The starter ring gear carries the oil around the top of the flywheel and it lands in the cup on the way down. From there the oil runs through a passage in the bellhousing, through a hole in the bellhousing gasket, and through a passage in the block back to the crankcase. I'm not sure how much of this you can get at through the hand hole in the block, but you can tell where it is from the outside by the odd bulge in the casting of the bellhousing. It is possible someone made a gasket for it without the hole, or plugged it with gasket goop when they had it appart. Good Luck
