Brake & Clutch Master Cylinder Sight Glass Replacement

[dingy]

Below is a cut & paste of the info I have regarding the company I got the crystals from.

 

I have had my brake master in since last spring. Crystal is still very clear and no leaks.

 

The one issue I had was some softening of the clutch side epoxy where it was on to thick. This new idea for an adhesive may work better.

 

I used 17.5 mm crystals x 2mm thick

 

I did not hone the bores as I couldn't find a hone that would fit .

@ dingy,

 

Hey, Thanx Alot For The Info dingy!!! Will Order Some Crystal Lenses Today Hopefully. Was Just Going To Put A Metal Electrical Box Slug In There And Spray A Ton Of Coats Of That Permatex Sealer Over The Darn Thing Just To Make Sure It Didn't Leak. I Usually Check All The Fluids Every 3-4 Days Any Way, So The Sight Glass Is Pretty Much Useless To Me Any Way. Thanx For The Info Again!

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.
