I am eliminating the primary chain oiling system on a buddies 76 FLH. According to the book the oil return is a gearcase breather (3/8 hose fitting). There is also a separate crankcase breather. Do you pull this fitting out of the case and plug the hole where the primary oil return goes or just routed this line to the vent Tee to the oil tank vent instead of the primary vent hose. So here's the plan. Plug the return and vent holes in the primary cover, use the oil feed fitting on the primary as a vent. Block off the oil feed line on the pump. Run a straight hose from pump to oil tank vent to eliminate the Tee that is currently in place and do something with the oil return fitting at the case. Your help would be appreciated. Thank you.

Yup.
You can actually do pretty much anything you want as long as the chain gets some oil and the crankcase can breath somehow or withstand the pressure. Personally I like it to breath. My crankcase vent hose just goes out to air under the right passenger footpeg (useful for seeing when the oil pump return check ball needs cleaning - wife says "WTF is that crap on my boot ?
), and my primary case is totally sealed (no breathing at all).
With a dry clutch, I just put oil in the primary up to the bottom of the clutch housing which covers the lower chain run.
I think from memory I have seen people reporting they run the 'dry' clutch wet with no apparent ill effects, but personally I can't see the point, except that it's mildly reassuring to know that a little oil getting in there won't hurt.
Again from memory, some run the crankcase breather into the carb, like on emissions control cages, which is tidier, but local regs here don't require it. Some States May Vary

Mine is there, and goes to the oil tank filler cap.

Hi Pete
I appreciate the pictures but that is not the line used to return oil from the Primary on the bike I am working on. It is located much lower on the case, to the right of the Crankcase breather. The line you show is the oil tank vent line. I found a diagram from an earlier post by Ed Y showing the return line fitting plugged. Yours may already have a plug in it. I really appreciate that you took the time to respond to my post. Thanks I may place a few calls to local dealer to find out for sure.

Sorry, I was fixated by 'engine case' - my bad
On mine ('79), the primary case return line goes into the oil pump behind and slightly above the oil pressure switch. I guess they made the change in 1987 1/2.
If so, mine's plugged, but I can't get a pic in there.
Just below it, and the oil pressure gauge, is the breather that normally goes to the air cleaner. Mine goes to air.
Just by logic, if the line returns used primary oil to the pump I can't think why you need it and I think you're safe to plug it, but no doubt wiser men than me will intervene if I'm wrong

Not sure exactly what you mean. If you have oil in the primary up to the clutch basket, that's a wet clutch, not a dry one...eh?petelogan said:
When you put any amount of oil in the primary, your plates will get soaked very quickly. Shouldn't be a problem. Mine have been in there for more than ten years with the same plates....60,000 miles. They don't seem to wear at all.....
Oh right I just meant running what the MoCo calls a 'dry' clutch with oil in there.
Dry as in three bolts, wet as in the later four bolts.

Gotcha. See what you mean....
Say, I heard recently that Luxembourg is the country with the lowest crime rate in the world. That sounds pretty good.
So, that means that you can ride your Harley to the store and leave it out in front with the motor idling and the key in it? Hee Hee. Sure!
NUC
Sure does. I've seen it done with a lot more expensive bikes than mine, like Wings and such. Helmet and jacket on them, too.
Apart from the odd justifiable homicide (wife kills husband etc ) there is Zero crime.
What there is, is minor street offences in the main city, always by ex-Yugoslav or Baltic refugees under 20.
Two years ago, we had a series of five armoured car heists, culminating in a Brit crew knocking over a bank at the airport.
The government amalgamated the previous two police forces into one, and sent Every officer who had not already done it on a tactical course. Now every money movement is shadowed by an Audi A6 with four officers armed with Hecklers, and a chopper.
Zero crime
I leave my outbuildings unlocked with north of 50G's worth of kit out there, and cages I leave out with the keys in for weeks on end. Bikes are never locked up and both have the keys in. 5 years here, and zero trouble.
It helps that every house has guns in it

Man, that's great. Hard to believe there could be a place like that. I went to a British Motorcycle show on Saturday and accidentally left my Harley-Davidson Dew Rag on the seat. Some miscreant stole it. In the U.S you can't leave anything lying around.
I placed a curse on the thief this afternoon with a Gypsy friend of mine. The thief will die in two days.
Yeah, UK in the south is like that. Kinda like that in the middle, too
Luxembourg is cool
