Motor Mount question
« on: September 17, 2014, 06:38:43 PM »
This might be an odd question.  When you remove your tranny, there really is nothing to support the engine from rocking back.  Does this put unwanted stress on rubber motor mounts to the point where it makes sense to support the back of the engine with a jack stand to prevent fracturing the rubber?

I would say yes if they are old mounts, but if they are fairly new I don't think it would be a big concern.  Come to think of it, though, if the mounts are old and kind of floppy you probably ought to replace them anyway.

Not only that, but the fan might kiss the radiator/shroud/trans lines/bottom of hood if you forgot to open the hood---and don't even turn the engine over without checking that fan/radiator clearance!  Ask me how I know this?  LOL   Joe-JDC

Or in the case of my 59 T-bird, the oil pan resting on (or bending) the power steering power cylinder. A piece of 4x6 lumber under the bellhousing rim takes just seconds to put underneath there.

Yep, experience is a great teacher :).  I use a hydraulic bottle jack and a block under the oil pan at the rear, shimmed to distribute the weight.  Useful at trans reinstall too, helps you get a convenient angle.  Never did trust that motor mounts would take the torque, guess I'm the cautious type.

OK, I'm not the only one that thought this might be a good idea.

A short length of chain running from the left side frame ( or other ridged surface ) to the left head will serve two purposes.  It will serve as a support when the tranny is removed and a short leash to keep from breaking the left side motor mount under severe FE torque.  Cheap insurance.
