motor mounts | The De Tomaso Forums

Guest

I was putting my car back together and I noticed the motor mounts don't seem to get real tight, its been about nine months since I'd taken the car apart and I can't remember if the center bolt through the rubber bushing was real tight in only seems to get snug at best. Is that right?

You're tightening the long central bolt against two rubber discs sandwiched between metal, so you shouldn't lean on the wrench too much. If you installed the long bolt from the top, you'll notice that the threaded end is drilled for a cotter pin to positively retain the nut against the effects of age, rubber shrinkage and vibration whitch will loosen it up no matter how tight you initially make it. If you installed the bolt nut-end-up as most people do, the cotter-pin hole is impossible to use, and at some point, the nut will loosen & the bolt and nut will drop out & be lost. Something to check on periodically.

I would exchange it for a 'NYLOCK' NUT, they can be found in any thread including Metric. And use a washer! Marlin.
