Looking for some advice on what I think is a oiler related issue. I'm finishing up my '76 750F1 project and since I've gotten alot of advice here and have never gotten it together to start a build thread here's a pick form last years "work out the bugs before final assembly". I've since finished the frame and I'm reassembling for the final time (hopefully). So I'm workin out the last of the bugs.

The issue: Getting tons of oil in the front sprocket area and on the chain. Long ago I had read something about plugging the oiler so I found a hole in the final drive shaft that I believed to be the oiler and welded it closed. Obviously this didn't do what I thought it would do as I'm bathing in oil from the chain when I ride this thing.

The interesting thing to me is that there is a large threaded opening at the end of the drive shaft where you would think a bolt would go to hold the sprocket on. I've looked at parts fiches and they only show a plate the turns into a notch on the shaft and two bolts holding it and the sprocket to the shaft. Is stopping the oil as simple as finding and installing a bolt here?

Thanks in advance.

What serial number is your engine, 1976 F1 model engine did not have an oiler.

Its an F1.

I would certainly believe that the oil is coming from something else. The seal is new and the cases bonded well. Something else?

1975 was the last year for the oiler, any cracks in your case around the sprocket ? Is your engine serial number above 250xxxxx4 ? You said you replaced the shaft seal correct. A picture of the sprocket shaft may be good for the F gurus like Jerry RX.

My serial # is e-252xxx4. And the main seal is new. Photo forthcoming.

Here's what we've got for a photo.

I just finished a 76F and there is no chain oiler that I saw. Are you oiling the chain a lot with regular oil and not chain oil and that is what you are seeing or do you have an oil leak near the countershaft?

This is probably not what you are seeing but I have had leaking from my left side engine cover from the screw holes. previous owner replaced screw with allen bolt and the bolt head wasnt wide enough to seal the plug hole. Dripped forever until I replaced the bolt with stock screws.

Never put any lube on it, was always oiled. Assumed it was an "oiler" issue. Guess the thing to do is fill it with oil, take the sprocket off and starter up.

Matt, you have the early type counter-shaft. The oil enters the center of the inside end of the shaft, and exits through the hole in the side. Since you have welded the side hole, all you need to do is thread an M14x 1.25 bolt or set-screw (with an appropriate sealer) into the shaft to plug the outside end.

I will be making some oiler eliminaters bolts soon.

scottly · « **Reply #11 on:** September 13, 2016, 08:15:58 PM »

Frank, FYI the stocker weighs about 26 grams.

I was waiting on that photo, and just saw it now. Scottly is right on, that shaft is from an earlier bike. Just plug the end with the bolt size he mentioned. (Or get one from Frank, I'd like one too!)

MattFreeman · « **Reply #15 on:** September 14, 2016, 08:17:50 AM »

Awesome!! I bought what was sold as a F1 trans awhile ago with extra stuff so I'm not surprised that it's not a F1 shaft. (it had a better bearing on it so I used it). I've been learning alot on this build and in some respects it's been a steep curve.

Thanks once again for all the help. Having that thread size is super helpful as well.

More info and price please....

I spent $20 on a Joker Machines one, but I'd has to be pressed on, not threaded. It's currently resting semi-pressed in the shaft.

Matt, check your chain aignment, just in case you have a wrong combo.
If you ran it a while look for sprocket rub on only one side..

Copy that, Thanks!

Frank, I got you beat by 4.8 grams.

Broached an internal hex with a sharpened Allen key; first time I've tried it..

This is something my CB750 need. I have just found out that I miss a fresh lock washer for the OEM oiler stuff, 90433-300-010
Your bolt need that washer too?
- Price? If washer is needed to lock it, you have that too?

754, I would like two please.

qside · « **Reply #22 on:** September 15, 2016, 03:58:12 AM »

I could use one too

ekpent · « **Reply #23 on:** September 15, 2016, 04:12:43 AM »
