Ok where is the oil?
 
I recently changed the oil in my 65 xlh. For some reason, I did not put any in the primary side. I have read in the manual that it shares the same oil as the crank case. (A common sump). I guess I assumed that it would use the oil in that. Went for a nice 30 mile ride and its noisey as all get out. I guess there wasnt a whole lot of oil in the primary side. Doesnt seem to have damaged anything but Im going to pull it down anyway.

Does a 1965 XLH use the same oil and does it get it from the common motor oil in the engine, or do I have to add it to the primary side as well? Some guys are using a heavy HD Primary oil. Should I be using that and if so, will it mix with the engine oil and cause some sort of damage?

Answer: Two separate systems. 3QTS in the tank for the crankcase, and 24oz or 1.5 pints for the primary.

Hint: Get a FSM or equivalent.

I would do a total tear down on the primary side, and check the friction plates very well.

Never Assume, You can use the same Oil but must fill the Primary side as per the proper capacity.. I use 60W on motor and trans.. Get a Service Manual........

The primary and crankcase may be separated. There is a factory transfer valve between the two that may have been sealed off, a thousand different ways. Or not. A lot can happen in 45 years...

The only way to know is to go in and look. Never assume the primary is oiled by the engine. The transfer valve allows the oils to mix, but the design is not intended to purposely lubricate the primary. A lot of people will separate the two, so that engine oil and primary oil don't mix. If that is the case, separate oils can be used in the engine and transmission.

GA thanks. I do know the transfer valve is still there. Ive always wondered why anyone would put a primary lube in the primary side if the transfer valve allows them to mix. Would that not destroy the engine oil if that happened. The book says that the oils are the same yet others use engine oil in the block and primary lube in the primary.. Whts your take on this

If the transfer valve is still in place, use the same oil in the motor and primary. If the transfer valve is plugged, use what ever makes you feel good. Either way change the oil regularly for best results.

The transfer valve is more of a breather than a oil transfer port. It is not meant to transfer oil from the crank to the primary. If allot of oil does transferrs through the valve from the crank to your primary it is broken and needs to be replaced or plugged as some do here.

I hope you didnt get too much damage.

The oil transfer valve allows oil from the crankcase to enter the primary side only if you have excess oil, or pressure in the crankcase.
Excess crankcase pressure from worn rings, or valve guides. Excess oil from the oil pump check valve seeping, or from other wet sumping problems.
If you plug the oil transfer valve, and still have the excess oil, or the excess crankcase pressure problem, then the oil will end up going out the breather pipe instead of going into the primary.
My brother always had to add to his oil tank, but drain about the same amount from the primary.

It seems that "oil transfer valve" is incorrect terminology. Can someone look this up in a parts book and post the actual correct name and part number please.
