DIY: Polyurethane Motor Mounts
OK, after 12k miles with my ACT clutch and flywheel, my rear transmission mount took a dump, so here is a DIY on making a PU mount.
Parts Needed:
Accurate Scale
Urethane Compound - $25 (avaiable at www.mcmaster.com)
Engine Mount(s) - available at Honda or www.hondaautomotiveparts.com
Here are the pics that pretty much describe the process. Curing time is approximately 2-3 days, I used artificail heat to accelerate the process. There are several hardnesses of urethane to use, I used 80 Shore A as alot of others have done that I know.
The urethane is mixed by weight, and should be mixed according to instructions that come with the urethane compound. There is enough urethane in a one pound kit to do all three of our mounts (rear trans., side trans., and front mount), the fourth mount is fluid filled and cannot be urethaned.
Duct tape or do something to the bottom of the mount because the urethane is liquid and will leak without a seal around the bottom of the mount!

how come mounts went after just 12,000 miles ? you must shift very hard and burnout? what stage clutch and weight flywheel did you have ?

Rep Power: 0 Most people leave the inside "webbing" of the stock mount in place and pour the urethane around it, which is what I did (so I did not modify the stock mount in any way).
I am not quite sure what did the mount in, I don't do burnouts or race or anything, I have the HD-SS clutch and street-lite flywheel. I noticed the mount starting to go this summer when the clutch started to "chatter" alot.
And no, noone makes urethane mounts for the d17 that can be bought.
This should hold up well, one of my friends has been using a mount made this way for a year or so with good results.
