Topic: Chain oiler

[Sandy]

Hello to everyone:

I have installed a new o-ring chain and do not need the automatic oiler.  My problem is - I did not know the bike (1969 CB750) had a chain oiler and it is copiously leaking down the center stand.  Several people said it is an easy task, but I cannot find where the bolt/nut is to turn off the oil flow.  I have removed the transmission cover and the front sprocket cover and I don't see it.  My guess is that I need to remove the front sprocket in order to see it.  Can anybody tell me where I can find this?  Thanks to everyone in advance.

Comes out the end of shaft in the center. What is in there now?

There is a plug you can buy that fits in there or you could use an old spark plug.

All you need to remove is the front sprocket cover to see it.

A flat head screwdriver should be all you need to close it off. Take off the sprocket cover, and turn that flathead in the centre of the sprocket all the way to the right.

Odds are the seal that helps to cut off oil flow will be well worn out when you try to turn it.
There are a few threads out there about this topic should you choose to study a little more on the subject.

Very early bikes (his?) the oiler wasn't adjustable I think. No screw to turn.

You can look for a blank off plug or do the ghetto broken porcelain d8ea trick. Threads right in. You could use the d8ea and use epoxy to make it look like a nice block off.

Thank you all for your responses and I think I might have it solved .  I have attached 2 pictures that show what I have now and what a D8EA spark plug looks like threaded into the orifice.  At least, it is threaded into what I think is the correct orifice .  I think I'll head off to the local hardware store and see what I can find.  Believe it is a 12mm x 1.5 pitch, but I'll be sure to take the D8EA with me for getting the proper threading.  I will let you all know if it works

You didn't have an oiler at all.... You put just about anything up in there and you will be good lol

PM me if you want a k6 oiler, it will function the same and close off the whole a little more stock honda

I like that spark plug trick! Looks awesome too

Well, here is what I did.  Went to the local hardware store and purchased a 12mm 1.25 pitch bolt.  I sawed off about 3/4" from the tip of the bolt.  Once that was complete, I Dremeled a straight line in the cut portion of the 3/4" thread so that a screwdriver could be used.  Wrapped the 3/4" piece with pipe tape and installed it.  Picture attached.  If it works, I won't be entering anymore posts to this thread .

I have made some lightweight plugs, they have an o ring  that seals in the critical area.
As long as you get it sealed that is the main thing.

There is a hole in the final drive shaft, in the splines, under where the sprocket comes to rest. That hole is where the oil comes from to lube the chain.  Your plug needs to be long enough to go into the drive shaft far enough to cover that hole. I think there are 2 holes, 180 deg apart.

The threads of the spark plug are long enogh to do that. Is your bolt long enough?

MCRider and 754:

Looks like I need to do a little more work on this .  I rode the bike about 100 miles yesterday, put it on the center stand and was anticipating great miracles in the morning .  Well, it looks like my plug didn't work completely , but it is much better than before.  I will pull the front sprocket and see what else is in there.  Here is a picture.  Thank you to all who replied.

I was reading through some posts on this site and came across this post of Frank’s.  I sort of knew Frank.  Met him a few times.  I once gave him a set of ‘73Z1 fork lowers.  Really decent guy.  He passed away a while back.

 When Franks posts come up, I always laugh at the googley eyes and then remember the big smile on nearly every picture of him. I miss his wisdom.
