Hey guys just bought a 1990 D250 Cummins 5-speed and it needed motor mounts and the trans mount wasnt even bolted in. Well I fixed that and put new motor mounts in it and the motor and shifter still torque up pretty bad. It must be a 2wd thing cause my other 90 is a 4wd and the motor nor the shifter move. Just wondering what you 2wd guys do to fix this problem and if there are any solid motor mounts i can put in. Thanks.

 

I would think that the vibration from a cummins with solid mounts would be unbearable. Just my .02

 

Yeh I realize that. What about poly mounts?

 

Poly would work but still would flex. Solid won't....you would break stuff.

 

I don't ever remember seeing poly mounts but that doesn't mean they aren't out there.

 

What about putting a torque chain on it? Bolt it to the driver side of the block somewhere and then bolt it to the frame. It would have to be a pretty beefy chain.

 

a chain in addtion to good stock mounts would probably be a good compromise.

Leave some slack in the chain so the engine can move a bit, otherwise you're just going to make it act more like a solid mount - and that won't be pretty ...

 

we got 5.9s in some forklifts in the army and they are solid mounted and i have seen them crack the block, break bolts, and one that puked up a rode. the rod was lake of oil not the mounts, but it was cool to see it keep on going tell it was shut down in my bay by the driver.

 

I think ill just chain it

 

Little pricy, but...

I run 2 stock mounts per side with a saddle mount. Seems to work well.

I bought a pair of mounts from Autoworld Montana, before Spiva @ Polybushings was selling them, but I still haven't gotten around to putting them on the truck . . .

 

I put solid mounts on my 'Cuda running an engine that was balanced to 1/3 of a gram, and it was very noisy, even with hydraulic lifters. A chain will be very noisy. Making a torque strap out of a towing strap would be the best of both worlds.

 

Towing strap might work. Maybe ill do that for now and save up for the poly mounts and a poly trans mount.
