Does any one know a good way to install these clips onto the tappets of a BSA A65 motor? Should you squash them down so they are a tight fit? From what I have found out so far is they get installed after the tappets are installed into bottom of the jug. There is also a tool to assist you but I am not 100% sure how it is to work,

I've rebuilt countless A series engines over the years and and never use them. Just liberally grease the tappets to keep them from falling out when you're ready to install the jugs...however since you have them, just push them down over the tappet shaft with a suitable piece of steel or copper tubing...the fit isn't all that critical, the only thing they do is keep the tappets from dropping out when fitting the cylinders.

^ plus on the thick axle grease, I've never put them back in for fear of them falling out,

What they said.

I get it....that all they do is keep the tappets in while assembling the top end. But when this scoot gets a new owner and the motor gets done again....well I can just hear the dude bitchin' bout no circlips!
If this were my biggest problem, I would be happy.
Seems there is a chunk missing from my second compression ring on one of my pistons.
I will post pic tonite. I was really hoping to have this motor together this weekend!

For reference... here is a pic of the service tool. Finding one may be an issue. Use a piece of pipe as suggested.

Why do you worry about the guy complaining about no circlips. Tell him up front and there will be no problems. These are just for assembly purposes only and have no affect on running.

What Old Codger said...why worry. For what its worth, most of the engines I have taken apart haven't had them in anyhow and I never felt the need to cast aspersions.

I've always just used 1/4 " fuel line, insall the tappets and push the hose over the ends, by way of the pushrod tunnel.

well I am gonna make a simple tool to do the job.Maybe tomorrow it will be done.
