Changing Top Engine Mount on a 172??

[mike]

Morning,

I've recently changed the bushes in my dog bone mount and also replaced the mount under the battery but am still getting the engine banging and also vibrating heavily under hard acceleration in first gear. Next will be to change the engine mount on the top left of the engine. Is this hard to do - can anyone give me a quick run through of how to do it? Also, any other ideas what's causing this banging and vibrating??

Cheers!!

quickly:
Realese 4 bolts that hold the mount itself + center bolt. Put jack under the engine oil sump and jack it until all the weight of the engine come on the jack. realese 3 bolts on part number 14 in the picture. Replace the mount and do all again at the reverse order.

You missed out the bit where you have to fix all the damage caused when jack goes through the sump...

Ok cheers, don't worry I'll use a block of wood on the jack!! Do you think this is the likely cause of the knocking/vibration, I'm running out of things to replace (I hope anyway!!). Does anyone have a part number to hand and cost?

Thanks!!

do a search on mounts; couple o days ago someone mentioned part numbers so in the search will almost be top of the list

As he asked, I wrote instructions. I sure that he know that need to paut something between the jack and sump.

Also remove the battery and check the mount under it. It may be good but with realesed bolts (I have it).

The RS models have an extra mount to those 3 you listed.

Tt is on the front nearside of the subframe at the bottom, and is a bit L shapedish
