John,
Use soap (kitchen washing -up detergent)and water. Don't use any oils or silicone as this will caused the parts to be lubricated and this is something you don't want. Once you have the damper assembled you don't want the parts sliding around, the soap and water will dry and the fit will remain good and tight as is intended.

Gentlemen, the drive pins and bushings that I received from Marcotte were 1/4" to long and bored out for bolts, instead of tapped for cap screws and when I assembled the couplings it would not bolt up because the base of the drive pins held the drive and driven disc's 1/8" to far apart and the bolts were interfering with the bell housing.  So a trip to the machinist and another $100.00 shot and removing the material in the bell housing so the bolts and nuts have room to rotate, I hope to reinstall the redrive again. 
 
Can I put baby powder or silicon on the rubber bushings to help with the assembly into the driven disc, the pins are really snug and are going to need quite a bit of pressure to get the six of them into place.  The silicon would work the best, but would it have a negative effect on the rubber and the operation of the coupling.  Thankyou for any input.  JohnD definitely frustrated in the country.
