Replace frame mounts and motor mounts.

Hello. My motor mounts are worn and likely the wrong ones (at least I think the frame mounts are wrong—for a big block), so I got a new set of both. The motor mounts are poly (flexible), as I was told they’d work well with what I have. Anyway, I’m a novice, to put it nicely. I don’t have an engine hoist. So any suggestions how I tackle this? Lift up using jack under oil pan?

Oh, and just to clear up what I just said, I have a small block (383). I think the frame mounts are for a big block. The last guy put some washers as spacers to make it work

And so I guess I’m just asking for tips on how to approach this. As far as lifting the engine, maybe try to use a two-by-four with the jack on the balancer?

Re: Replace frame mounts and motor mounts.

I'm not really following what you want to do.

Are you trying to lift the engine from below and replace the motor mounts and frame stands ?

If so you want to do it one at a time using plywood to protect the the oil pan.

Not exactly easy for a novice. Can be dangerous.

Re: Replace frame mounts and motor mounts.

NO don't jack on the balancer. Jack on the oil pan. ( IMHO). Protect the pan like Beth said. Watch the fan shroud, hoses, and distributor when jacking. Only jack enough to free up the mount....Jb

Yep, the danger is what I’m concerned about, don’t want to lose any fingers. So use some plywood under the oil pan?

Any tips about the bolts? They are hard to get to (not much room for a socket) and I don’t want to strip them

I’m finding now that the frame mount bolts might be a hassle, as the nuts are almost impossible to get to (there’s only a small, perfectly round hole in the subframe). How to get to that bolt?

Ratchet with long extension to reach up inside the subframe to get to the nuts.

That gets them off. The trick is getting them back on. 🤔

Re: Replace frame mounts and motor mounts.

I never had a problem putting them back on. Use a shallow socket with a long extension. Put some "dum-dum" on the socket and push the nut on to it. This way the nut won't fall off while you have it up inside the subframe.

Bolt should be inserted from the bottom, nut on top. Standard structural stuff. Nut comes loose bolt falls off you see a hole. Bolt from the top, nut falls off you see a bolt head and don't know the nut is off.
