engine and gearbox

Post by stuupnorth »

Hi all
yet another questions for all you wizards of knowledge
replaced old engine with a rebuilt 1275 and box
firstly the engine was removed on its own ie remove l/h engine mount and turn engine 90 degrees and take out no problem
so far
then gearbox out again no real problems there
new engine in and box along with all new rubber mounts(engine and gearbox)
noted that the rubber mounts seem to be very hard ? once engine in (replace l/h mount ) the engine steady bar slipped on to
the rear of the cylinder head without any adjustment what's so ever(surprised me and leading me to believe the engine is in the same place as the old one)
the gear box mount /cross member is on and lined up with the captive bolts in the chassis
it seems that the engine is pretty solid is that ok? there doesn't seem to be much if any 'give' in the rubber mounts ,or is it that i was so used to the old ones moving so much??

New engine mounts do tend to be stiffer/firmer than the original factory items.

They will start out far stiffer than old well flexed and strained mounts.

They are there to support the engine/gearbox as rigidly as practical, resist turning forces, etc. The reason they have rubber pads/inserts in the mountings is to avoid vibrations being transmitted to the chassis as well as absorbing shock loads to some extent.
