After paying 220.00 for the new rubbers I want them to last.I need to use some lubricant to help slide them into the front mount as well as the cradle does any one have a easy way before I use WD-40.

Mineral oil worked pretty well for me.

I used rubber grease with great success,

P-80 temporary rubber assembly lube. You can get a sample on line for free if you can wait. ipcol.com but it's no preservative.

But I used silicone grease on mine, I had some around.

Yep about anything will work to help ease in the cushions, even baby power so my advice is once the first edge started, whack the whole mount into its tube by one good bash with something massive and bolt end protected, then a few raps to center the cushions. Even easier if some bevel removal of the cushion contacts which gives a nice soft ride too.

It's best to not use petroleum-based lubricants for this purpose though everybody seems to do it. Rubber and petro do not really mix well. A better lubricant is a silicone-based grease, like dielectric grease which will not affect rubber in any way. Since you probably have a tube of di-electric grease around for all the electrical connections, use that!

If the rubbers were sealing anything then yep avoid the rubber solvent oxidizing lubes that can weaken/soften, but its about impossilbe to hurt the big cushions function even if almost crumble soft I've found. Fortunately there are very few solvents available to us or in various lubes even if ya did want to soften rubber, like I do on my old hard tires or already too soft race rubber, so I stand on my shade tree advice to use what ever at hand and grit teeth for the one shot insertion caveman method.

I agree with dog t. Comnoz mentioned that stuff on here before and I got the free sample pack and it worked great on the iso's buy I've also used it on multiple other projects since

Dielectric grease smears on thick and holds it's consistency forever. If you can get a hold of some, use it.

I dont use nothing, so it will be always almost clean.

Ugh, the issue I've run into w/o lube coating of some sort is the tube surfaces rust up to velvety velcro textures that make the cushions a terror to remove.

Ditto.

Silicone grease is the correct item. NAPA sells it as something called Sil-Glyde, good for keeping gaiters and such protected too. An 8 oz tube will last you a lifetime.

Dielectric grease is also silicone based.

Good old Wikipedia.

It's a good idea to try to get the inside of the tube as clean as you can get it. It's important when you are setting up the iso's that they are able to move freely. If they're not, then the iso on one side is going to be loaded or pressing on one side. If that's the side you're checking with your feeler gauge then your measurements are going to be difficult to get right. I tried hitting them with a cheap flexible hone.

Silicone grease here too.
Mine is for cycles, and if you buy it from the sort of shop where they say 'rad' and 'aw-some' all the time you'll probably get it cheaper elsewhere

As long as it will dissipate and leave no residue.

the thing that sold me on the p80 is when you start reading about the effects certain products have on rubber, and how the p80 was made to use with rubber

motoracer8 · May 6, 2013

Regular tire lube made for mounting tires works fine, and it's cheap.

Brendan S · May 7, 2013

P80 also. It's also great for rubber seal installation, like the ones in the timing cover.

Which of the P 80 products? Website has several types.
