-----Question-----
Hi Mike!
I wish you will have time to help a hopeless HD fan far far far away from the US!
I own an FLH 1970 which seems to be in a preety original condition - BUT the connections in the oil pump seems to be completely different from the one I see in the OEM service manual of 1970.
Because the OEM manual is regarding the ‘network’ of oil lines a really poor advice, I will higly appreciate if you could give me some light in the following troubles!
A) The front chain oiler fitting in the top of the pump (vertical fitting) has been removed and pluged. Is this normal?
B) The front chain housing has been removed from all vent/oil lines! Why should such an ‘horrible’ thing have been done? The primary cover has an air intake in the area of the engine sprocket. May this ‘vented’ cover be the reason?
C) The crankcase breather (to the atmosphere) has not fitting at all (is just a hole in the engine housing well hidden behind the pump). Is this OK? Is a fitting for the protection against dirt missing?
D) I am mostly confused about a certain Tee-fitting (OEM 63541-70) mounted again on the crankcase near to the inner side of the oil pump where I believe should be the return line from the primary housing. Is this fitting right in an FLH 1970? What are the two connections in this fitting for? (a big horizontal and a small vertical one).
E) The 45 degree outlet in the pump, near the rear chain oiler adjusting screw is for the rear chain oiler line, isn’t? In my bike, this outlet is connected to the overmentioned Tee-fitting with a 2 inch short line (some kind of by-pass)! I see none of this in the service manual… Is this normal?
F) The last one, Mike! I actually started to get a closer look to this whole issue when my Shovel started to loose almost all the oil through the rear chain oiler! By moving the engine with the kick pedal you could clearly hear strong ‘breathing’ noise and generous oil ‘spitting’ coming out the rear chain oiler line. Is it a dirty check valve after a couple of months without running the responsible for flooding the crankcase with oil? If this is the case, why did all this oil came through the rear chain oiler line and was not just driven back to the oil tank?
This shovel features an OEM oil cooler. I do not know if this means something to my questions!
Many thanks in advance for your time, Mike, and my best regards from Liechtenstein!
Christian.

Check your primary, are you running a belt or is there oil in there?
Mike
Answer(c) You should have a fitting on there with a hose. Keeps oil from blowing on the trans. Install the hose so it points to the ground.
(d) Yes the fitting should be there if you were running oil in the primary. Since youa re running a belt, dont worry about them.
(e) Yes its for the rear chain oiler. Previous owner probaby didnt run it to the chain. Alot of people did this so they didnt have to deal with the oil flying back on the tire and wheel. Just check the chain every once in a while and lube it with chain oil.
(f) Your chain oiler shouldnt have that much oil. Locate the screw to shut it off and turn it in. That should shut it off
Good luck and happy riding
Mike
