How to replace motor mount covers (heat shield) - ZR-1 Net Registry Forums

HAWAIIZR-1 · 07-18-2010

As most of you know I am rebuilding my motor and discovered I had a broken motor mount when I pulled the LT5. I bought new motor mounts (OEM) and could not find the shield or material that covers the motor mounts to protect against heat.

So I had to improvise and make my own so sharing what I did for those that are interested.

The orginal material was trashed so I found this Helix 12" X 40" sheet for under $20 and decided to use it. I think the better material might be from DEI or Cool It (Thermo-Tec) brand of kevlar backing but too expensive for me and this appears to be what the orginal material was.

The first step was to make a pattern of the material. The original piece is a little larger than 12" and has folded edges but what I bought will do for my purpose. So I cut a 12" X 12" piece.

The next step is to transfer the thick fiberglass type of cloth from the OEM cover and I trimmed to fit.

The material I used had adhesive which I did not initially like, but it worked out best to me. I removed the backing for the adhesive and folded the corners together first. Then I made the fiberglass cloth as small as possible and placed in the center and secured to the shape matching the bolt holes for the mount, etc.

First I wiped the motor mount bracket clean with mineral spirits and disposable towels and placed the shield into the bracket as shown.

The motor mount is placed into the bracket and hand tight bolted in.
