Transmission vs. Crank Case Oil

Tue Mar 28, 2006 4:27 pm » Post: #1 » Download Post

Transmission/gear oil is separate from the Crank case oil, yes? The crank case / bearing gets it's oil from the 2 stroke oil, yes? So, is there always going to be visible signs of oil in the crankcase? I am rebuilding the top end and looking down the crank case from the top, I notice there is a puddle of oil in there more than usual. Is this normal?

I wouldn't expect to see a "puddle" of oil in the bottom of the cases, but they will most likely be wet... unless you are building it because one side seized through poor lubrication!!

Answer to the other question is yes... 2T lubes the crank bearings, transmission oil/4T engine oil lubes the gearbox.

I'd not worry about it.
It's just the oil from the last and unburnt charge that has collected at the lowest point plus any bleed off from the oil injection system.

If it were an RG500 you would laugh as the infamous dodgy oil check valve issue usually leave the void behind the inner RV covers full of oil and if let stand, the carbs on the lower cylinders end up half full of uninjected oil.....

Just rebuild and fire up.
