Re: Transmission mount or rear mount

Hey Lyle,
I replaced the bushing in my shift linkage with a piece of urethane spring material I had laying around. I think it was purchased from MSC. It comes in different diameters, lengths and hardnesses. The material I have is red in color which I think dictates the hardness, it's 1 1/4" diameter and I beleive came in a 12" stick. I cut it to the desired width with a hack saw, shaped it with a die grinder and drilled a hole thru it. It seems to work fine and certanly got rid of most of the play in the shifter.

Paul, another good idea.
I machine a lot of plastic in my shop, Delrin mostly.
Delrin is great to machine and stable, but too hard for bushings.
Urethane in it's softest compound is hard to hold and machine, but a perfect material for bushings.
I used to make plastic injection molds for a living until everything was sent to China......don't get me started.
I don't know much about the shrinkage or hardness of Devcon or other liquid type plastics. But making a simple aluminum mold would be an easy/cheap way to reproduce some of our rubber parts.
Or we could even make a mold from a good "old" part.
Something to think about.
If every member made one reproduction part for our Honda's we would be all set! I am sure we have a diverse group of skilled people in this club.
Other car clubs have done this.

Marshall,
Update on rear engine mount repair.  I initially welded it solid......Bad game plan!  It caused an enormous amount of vibration inside the car.  Since I had an extra tube of windshield urethane laying around I gave it a try.  So far, it seems to work fine.  I filled the entire cavity of the mount with urethane which is more solid than the factory rubber but doesn't seem to cause any vibration issues. It did take a very long time to dry due to the thickness.  If someone else wanted to use this method of repair, I would recommend filling half the cavity with urethane and letting it dry before filling the other half.
Devcon 80 is probably a better product to use but a tube of urethane at the local glass shop cost me about $6.50.

Hi Blake, Devcon products are expensive in UK. Windshield urethane may be worth considering as an economic alternative, although Devcon 80 & 94 are made for such a job !
