Can I make an engine mount rubber?
millenniumtree - 16/5/07 at 10:19 PM

Is it possible to carve my own chunk of rubber for an engine mount, or would it just be easier to buy one made for the job?

If anyone _has_ made one, what type of rubber did you use? Can I use anything other than rubber?

The mounts on my pickup are shot, and I just need something for a while before I Locosterize it in a year or two.

why on earth wouldn't you just buy one (or two) surely there not that dear, plus - they probably aren't just a block of rubber and most likely have a couple of studs/plate fitted internally?

Frankly, I don't know what they are exactly! I know there's rubber in them and guess I thought you could just replace the rubbers.

If you're familiar with 22R engine mounts, do tell. I'll have a closer look at them later.

Oh good lord.

They're complicated AND expensive.

Any chance of doing this bodgerly and cheap??

Couple bits of wood? (Only half joking)

Not keen on spending $75 on a $280 donor. Unless I'll be using the mounts in the Locost as well?

don't know how easy it is to get hold of, or how good the results are though...

Drill a hole straight through the lot and put a bolt through it, old Renault remedy

Looks like cool stuff, but expensive!!
Maybe I could get some thick vulcanized rubber and laminate it together with some flexible adhesive... As long as I can get the job done for less than $20, I'll be happy.
Possibly a small bag of shredded tire rubber mulch and mold it using a flexible cement adhesive/crack filler... That should hold together for quite some time - may even last longer than a new rubber!

Any more neat ideas? What can I make out of.....
Breakfast cereal and wingnuts?? Go!!

The whole point of the mount is to isolate the engine; proper mounts are bonded in the manufacturing process so the only connection between engine and chassis is rubber. If you bolt through in some way expect as a minimum a bit more vibration, at worst something having to give (chassis!) - if the engine is pretty smooth and you drive smoothly then you may get away with a rigid mechanical mount.

made some custom mounts a few years ago using some belzona liquid rubber cant remeber which one one i used, just told their technical department i do remember though that it was messy as hell and involved making a mould but did work very

Can't you find one in the scrap yard? Cheap and simple fix?

funnily enough I've considered the DI@Y approach.

I rec,on of one was stuck, one could use car tyre - nice and cheap.

You couldn't/shouldn't bolt it straight through as that defeats the object but use two or more bolts offset to hold the sandwich together, lilke below.

can't see why that wouldn't work, you would need peeny washer or plates to stop the bolt heads from pulling through.

Could you use Land Rover mounts with the bottom plate off the Toyota mounts? I saw this on Yankee eBay for less than the Toyota ones:

Also here: http://www.roversdownsouth.com/trans.htm

Not as cheap as here, though (I used these for my engine and for my exhaust)

Land rover V8 mount are simple and effective and can be used in conjunction with any plate or mounting you care to make.

I used two and they cost £3.00 each.

You aint going to make something for that price!!!!


02GF74 - 17/5/07 at 12:49 PM

I could; plenty of dumped tyres ..... but would you want to? No.!!


millenniumtree - 17/5/07 at 01:17 PM

Wow, these are slick.

Cost about $80 more than the car did though!

The cheapest I can find these for all 3 original mounts (2 fronts and a rear, which is different), is $99 + shipping.

Some bits of wood are looking quite attractive right now.

I _DO_ have an old tyre in the back of the truck, and bolts are cheap...
I don't think I'd be very fond of cutting chunks out of a tire though.
I'll ring up the scrapyard to see how much they want for 'em before I do something foolish.

Not sure about the land rover option - may be worth considering though.

In any case, it'll have to wait for at least a few weeks because my wife won't let me touch the truck until we get some of our bathroom constructed.
