I desperately need a quick fix. Can you help please?

.
My machine loses oil from the primary chain case when it's in the garage.
Not a lot, but it's a nuisance.

Since I'm used to British bikes, I'm used to my bike water thoughtfully water-proofing my boots as I ride.
But this leak doesn't provide that useful function.
On second thoughts, perhaps I should leave my boots under leak?

Is there a quick fix for a dripping oil feed to the primary chain please?

Thanks, Mike

Mike, you do know that it's suppose to leak oil......right? There's a vent tube located on the side of the engine and it sprays a mist of oil on the primary chain.......there's no return for this oil except gravity. If you don't like the mess....maybe invest in a belt drive and plug the tube..... :idea:

Mike,
I don't think Kurt noticed you said the bike was losing oil when it was parked. This is most likely sumping, caused by a weak spring or a bad check ball in your feed pump.

Quick fix ? try a ladies maxi pad, cable tie it to the bottom of primary cover, change it once a month ! Tim

Thanks Kurt.

Thanks Chris.
Can I just change the ball and spring please?
Or do I need to do something to the seat while I'm in there please?

Thanks Tim.
Nice lateral thinking.
What do you reckon to nappies versus maxi-pads?

IMO sumping doesn't usually cause leaking while parked but will pump oil past the rings and exit the breather when started, might want to check the primary chain oiler screw adjustment, are you sure its not trans. lube ?

I once had a Panhead that would sump and run out on the floor while sitting. When started it would puke another cup or two. A new oil pump body cured the problem.
The chain oiler won't puke oil unless the engine is running.

Thanks Tim,and thanks Chris.

My engine doesn't blow smoke on start-up.
It doesn't throw oil when I start it.

I've slowed the oil feed to the primary chain down to almost zero.

I'm pretty sure it's engine oil not transmission oil because it's black.
The transmission oil is still clean.
(Well clean-ish)

Re: I desperately need a quick fix. Can you help please?

Don't forget another problem. Some aftermarket oil tanks have the case vent line curved too far down into the oil tank. Now, when the tank is filled to it's normal level of oil, at least a quart can be siphoned down into the gearcase, leading to the false impression of a faulty oil pump check valve. Same results. Oil all over the floor. Easy fix. Put one less quart in the aftermarket tank. Or, find an OEM tank.

Thanks Jack, That AM oil tank info is a revelation. I wonder if the repop people would consider shorting that tube!

Thank you very much for that interesting titbit of information Jack.

I'm pretty sure I've got an OEM oil tank.
My machine hasn't had a serious spanner laid on it for 30 years.

Even now, I'm keeping my spanner work as light hearted as possible.

Thanks, Mike

My 45 sumps whenever it feels like it :( . Have 'done' the pump ball seats to no noticable effect.
Running the bike every week or so during the winter shoves the oil back into the tank & saves having to wring out the old carpet under the bike.

Mark!

When you "done" the ball checks, did you burnish the seats, or just abuse them by lapping or applying a chattering cutter?

Try http://www.resurrectioncycle.com/ for a tool that makes ballcheck seats approach perfection.

Ever see a Harley that could sit for all winter and still have a full oiltank?
I have.

If Reserection has it they are hiding it from their web site.

Thanks for the info about the seats Chris, Mark, and Cotten.

Who is 'Steve' please Pa?
Does the seat tool have a special name please?

Can anyone tell me where the feed to the primary chain oiler comes off the pump circuit please?
Does it perhaps come off from between the 'check valve' and the 'pressure regulating valve'?

Thanks Mike.

:shock: Me ? abuse parts of my motorcycle ? - shame on you !!!
Re-machined & burnished the seats with a burnisher held in an aligning bush.
Still sumps, not everytime it sits for a week but when it feels like it.
(Maybe it just takes offence when it gets rode hard & put away wet.)

Re: I desperately need a quick fix. Can you help please?

Mark!

Just to make certain we are on the same page,...Your burnisher is a screw-press tool with a ball on the end? No metal removed in the process?

First, I must admit that my success with burnishing isn't 100%, but damba close.
Success depends a great deal upon the condition of the worn seat.

If it has been punched with a drift some time in the past (most of these machines are older than we are, so I'm not pointing blame), or the seat has been widened by lapping, gouged by a cutter, etc., then somehow we must get back to 'zero' before the burnisher can work properly.
Just like a cylinderhead valve, the seat must be narrow to seal completely, and with oil involved, the final finish must have a mill profile that is smaller than an oil molecule. (Thank Gawd they are big!)

I would post a pic of my simple piloted conical stone for a pre-dress, and my home-cooked burnisher as well, but attachments are still a gliche for the forum.

With a little thought you can conjure them for yourself.
