Putting the clutch master cylinder back together

[tdskip]

OK - so here is the documentation on putting the clutch master back together. Please point out any errors so I can correct the steps.

Getting ready to be honed;

Spray the bore with WD40 to help prevent scoring the bore;

I've been coached not to "over" hone the clutch M/C, a little will do;

Wash it out well using tap water;

Dry it out in prep for the rebuild;

Ready for the plunger to be rebuilt now;

OK - time to start the plunger;

You first have to "unlock" the spring assembly, you do that bu gently lifting up on the tab;

Once you do that you can separate the piston;

You then remove the rubber ring on the pistion

Peel it all the way off

Then push the new one one. The side with the indentation/ring faces back towards the spring like shown here;

Next is the spring and fittings on the other end;

Pull the "crown" fitting down;

And then peel off the rubber boot. if you look closely you can see how torn up this one was, hence the leaking.

Put the new rubber on

Put the curved washer and crown back on

It should look like this when it is ready to rejoined with the piston

Guide the spring up over the end of the piston and then press the tab back down securely;

It is now ready to be reinstalled!

Then push the new one one. The side with the indentation/ring faces back towards the spring like shown here;

A little clean brake fluid will help lubricate the process.

And then peel off the rubber boot. if you look closely you can see how torn up this one was, hence the leaking.

I'd call that a "seal" rather than a boot. Normally, it's easier to remove/install over the small end

Overall, it all looks good to me. Two bits that perhaps could be clearer : sliding the link (inside the spring) to one side to remove it from the cup-shaped clip, and being sure the link fits into the center of the piston when reassembling the clip onto the piston.

Good work, Tom!

Tom, don't forget the circlip; I didn't know about mine, and Randall pointed me in the right direction (as usual)...

Tom-

Excellent stuff here - any thoughts of saving it to the Wiki for future use?

I put it back, but didn't document it. I should have, especially having just read that post where some PO never reinstalled it! Yikes.

Thanks for pointing that out Kevin!

That is what I was thinking Randy. I've learned so much from everyone here so when I have to do something that I haven't seen documented (or with as much focus on newbies like me) I try to write it up. The Buckeye Triumph site does have a very good write up, but I thought that some additional pictures of the details might help.

I have fooled around with the wiki yet, can I largely just cut and paste?

One thing, on reinstalling the clip, it's a good idea to make sure you install it properly. There will be a bevel edge and a sharp corner edge. The sharp corner needs to go in properly.

Ahola Ron - good point. Thanks.

Randall - My camera doesn't like the white paper towell in the background, will try a different surface next time.

Tom, Irfanview is really cheap (free), and does a good job at fixing things like that. https://www.irfanview.com/ The photo I posted above is a copy of yours, with just a quick crop and shift-U.
