How do they get the rubber to stick when they make engine mounts?
This is what i want to know.

Thanks

I think the rubber is molded to the steel during manufacture. I'd guess the steel is chemically etched before entering the mold, and there's probably also some temperature involved.

If you want to try a short term fix, cyano-acrylate should to a pretty good job. Try a gel type, to give you half a chance to get things lined up properly.

Good luck,

Scott

Thanks,
I have thought about using super glue but have doubts about it sticking with long term oil immersion ?

Anyway this is the problem. I have done a shave on the landy rear diff. All good except i have butchered the diff cover. It warped way bad when i did the cover chop and welding on it. This i now know - MAKE SURE THE COVER IS BOLTED DOWN TIGHT TO THE DIFF WHEN WELDING.

What i want to do is bond 1/4" rubber to the cover as a permanent gasket setup. If i can get silicone to stick i don't mind using it, but again i have doubts about its long term ability to stick when in constant oil contact. (i know its not an issue normally, but i have some biggish gaps to plug)

Have also thought about just welding the cover to the diff I only do around 10k a year, so if i have set it up right, the diff should last a life time. ?

Yep i am rough as guts, I yam what i yam.

what about sikaflex?

There area few places around that make custom engine mounts. I always understood that they used some seriously good adhesives ie glue.

Remember, the bond only needs to be as strong as rubber. Any stronger is pointless because if the mount gets that stressed, the rubber tears anyway.

But I could be wrong.

vulcanising

can't you just press or hammer the diff cover flat again? or if it's thick stuff just mill or get someone to mill it flat? failing that i't try the sikaflex

i have a bumpstop that has fallen off
anyone got some good glue handy?

Loctie 501, that shit will glue anything !

someone had to

If fairy land isnt too far away from brisbane you could try www.rollersandliners.com.au they can sort out engine mounts.

popeye - even with a nice flat diff cover it is hard to get a good oil-tight seal on a heaily shaved salisbury with a stock or modified stock cover. Mine weeps slightly, even though it is flat and I use a lot of sikaflex.

Your best bet is to buy or make a Dana 60 diff ring:

These cost US$30 and are laser cut from 3/8" steel. Would be easy to make yourself with a template and a plasma cutter. Then just shave the diff ring the same as your diff and weld a "cover" in the middle.

they do make oil/petrol/solvent proof silastic you know. they sell it at repco and other places, i doubt it will ever leak. Cost 10 bucks or so for a small tube. your a Landy owner, take the cheapest solution. you know you want to.

There is a workshop at Mildura Victoria that makes conveyor belts etc. and they also vulcanise rubber to steel. We sent our conveyor belt rollers there for revulcanising when I used to work at the meatworks.
They would vulcanise any part though.

Cant remember their name but I'm sure there are a few others around that do this service too.
Yellow pages?
