Default Brake & Clutch Master Cylinder Sight Glass Replacement

Would anyone be interested in the purchasing of replacement sight glasses for the Brake & Clutch master cylinders?

I know that there are some of these that have discolored or leaked in these older bikes.

I have just finished replacing both of my sight glasses with a mineral glass watch crystal.

I wanted to powder coat my master cylinders. To do this, I needed to remove the sight glass as it would not take the heat of the curing process. In doing so, I destroyed the sight.

I have replaced both of these now with the watch crystal. I used quick setting jewelers 2 part epoxy to bond into housing.

I had to buy 3 crystals & the epoxy to meet suppliers minimum order. I have had the extra crystal soaking in brake fluid for several days now. It shows no signs of discoloration.

If I could do a bulk purchase, it would cost $12.00 for two crystals, including shipping to you.

If you wanted, I could also get the two part epoxy for another $5.00.

I know these work on 1st gen bikes, but I am not sure about 2nd gens.

The crystal I used is 17.5 mm dia., & 2mm thick.

1st picture is of old sight removed & O ring that is under it.

2nd picture is of installed crystal.

Let me know if interested.



Gary

i would have a concern with the brake fluid having a reaction with the epoxy, does it seem to hold up?

From what I have been able to locate on the internet, Epoxy is brake fluid resistant.

I have not yet tested the epoxy for a reaction to brake fluid though.

I have mixed enough epoxy to fill a bottle cap half way up. I will let it harden over night. In the morning I will remove epoxy plug from bottle cap, and submerge in brake fluid.

Default Sounds very interesting!

Gary,


It's another fine mess you have gotten me into! Just when I thought I had the bike ready for warm weather riding, you show up with another kit to fix something I had blissfully ignored. My sight glasses on my '83 standard are really in need of this repair if it proves to be reliable.

Please keep us informed when you are confident with the components that make up the repair kit. I would really like to be able to see the fluid level in my clutch and brake master cylinders again...

Sigh... Day late and a dollar short... Story of my life. I just bought a set of very clean clutch and brake master assemblies with clear sight glasses off Ebay to replace those on the '83. They were getting to look and feel like swiss cheese.... However I am tempted to pick up a set of the crystals just because. Gary, let me know if you need to add a few more to a batch.

In the XJBikes forum they've been replacing the sight glass with a watch crystal epoxied into place for years. I've heard of no problems with the fix.

I have had brake fluid in the clutch master cylinder for a week now.

There is no sign of any degradation of the epoxy cement.

The watch crystal is still clear as glass.

The epoxy slug also looked OK. It finally ate through the plastic lid I had it submerged in brake fluid.

Going to be nice. Why did you decide to change the engine? I have a thing about those 1200's.

Arrow I used gasket silicone

Hi,

I did similar glass replacement on my red bike last fall. This bike came to me with severely deteriorated sight glasses. One was actually breached and the other was quite swollen and ready to breach any moment.

I used a gasoline proof gasket silicone as my bonding agent. I checked with the mfg first and they said brake fluid would be no problem for this product.

I did the job while the reservoirs were still on the bike. I think I loosened the fixing clamp to rotate the reservoir around the handlebar a bit to get gravity onto my side.

I cut my own glass disk for the first one but that was enough of that! I bought a bunch from a jewelers supply house in California. This was well worth the price given the difficutly of cutting my own.

The ones I bought are a bit smaller diameter than I would have gone for with the benefit of hind sight. I bought them based on measurements I took anticipating not removing a metal insert that holds the OEM ones in place. For some reason I had to remove this metal insert which made the available diameter of the recess a mm or so bigger. All in all though, the ones I have worked fine just aren't 100% optimal.

It was a bit fiddly getting a neat job but it turned out OK. I cleaned out the recess where the glass sits and put the adhesive in there with a small spatula. Then I pushed the glass in and let the silicone displace to take up the gap. I wished I had used slightly less than I did as there is some excess on the inside but I am OK with it.

Holding the glass while I did this was the fiddly part. The solution I found was to use some clear shipping tape to fashion a flap that I could hold on to. To do this I took a piece of tape and folded it over on itself for about 3/4" but kept the sticky ends free which I stuck to the glass with the flap protruding at the centre line of the glass. I then cut the excess around the circumference of the glass. This worked very well. I hope I have described it clearly enough.

Its been standing all winter with brake fluid in and no leaks so far as I have seen.

I still have several glasses left over so give me a shout if you want a pair.

Hope this is of interest and helpful.

Brian H.

I would like a pair of something and the epoxy. I have JB Weld over one of the holes because it was leaking it was so bad. I had been hoping a resolution to this had been found. I had even been tempted at buying new MC's.

I have not seen the brake fluid level through the site glass's for prolly 14 years.
