saving the isolastics

mschlake21 · Nov 1, 2016

im in the process of stripping my bike for powder coat. i have it all broken down now to the frame with cradle and motor. i can get the motor and trans out easy enough, I've already done it once when i got the bike. The PO was doing a quick restoration and had installed the adjustable type isolastics. They are new and id like to save them. so heres my question.... how on earth do i get these puppies out undamaged? i can't figure out how to remove them, much less remove them without destroying them

Paint the isolastic housings.

Possibly a small blade screwdriver slid between the tube and bushing, while lubricating the entire bushing with a soap solution. After going around the bushing in this manner, you should then be able to put a large bolt through the center hole, and rotate the bushing until it is sideways in the bore, and pop it out.

If they don't push out by thumb pressure, you just need to squirt some WD40 in the main tube (both ends), screw the end cap adjuster back on, and pop it smartly with a plastic hammer. It should then push out with thumb pressure. If not, slip a large washer over the end of the center pipe, then slip a short section of PVC over it, and smack it out with repeated blows with a plastic hammer. The iso unit will not be harmed.

As they are supposed to be adjustable (vernier) Isolastics, the rubbers are likely to be the 'one-piece' type bonded to the full-length tube so must come out as such.

I'd be inclined to use rubber grease rather than WD40, I am not sure how well the rubbers would stand up to mineral oil based products.

Hi,

as already mentioned, it is not advisable to let the craddle and isolatic housing powder coated. Even the mounting of the swinging arm would be a problem. I would paint them.

As long as you mask and powdercoat per Old Britts patterns, it works great. Rust-O-Leum gloss black on the masked areas (thin, even coat) keeps rust from ever happening.

WD-40 evaporates too quickly to do any harm, I use it to mount tyres on rims and handle bar grips, only issue is that once dry trying to move things can be difficult until you spray more on. Which is why if works on grips but you need to be quick getting the tyre in the right place by pumping in air.
