Changing Engine Mounts

[theKnifeArtist]

So i can't find anything in the tsrm about the motor mounts.
It's gotta be in there, but i dont see it.

So how hard would it be to swap motor mounts from one pre89 to another?
Is it as easy as holding up the engine, removing bolt, removing mount, reinstall....or what else is involved here?

thanks

It has been a while since I have worked on a 7M. I do beleive all you have to do is support the engine and remove the mount. You may have to removed the mount bracket along with the mount. I can see it being a pain to get at everything from the top without removing the downpipe so you may want to plan on doing it from below.

its pretty straightforward. why do one pre 89 to another pre 89 though? the round ones go bad but i havent seen or heard of a square one going bad..

Along with doing them with the motor in the car - which looks pretty tough. What is the proper torque specs on the motor mounts. I have searched and searched the TSRM and can't find the spec on them. Seems odd for Toyota to leave something that important out?

I just purchased 98 turbo mounts so I will be doing this soon.

torque on those doesnt really matter, they actually have a guide for the size of bolt / threading etc and how much to torque at the beginning of the tsrm.. as long as its tight and not loose

Yes I have seen the bolt guide but am unsure of the bolt grade to determine the correct torque.

exactly!
let's just say the supra in for the change has the "wrong" mounts



So what's going to be in my way of doing motor mounts with the engine in the car?

 

[mk3supra]

Iv had to do this before and it was a pain. The driver side wasnt bad and didnt take long. The turbo gets in the way on the passenger side. I ended up pulling the turbo/down pipe out to be able to get to all the bolts. I had to go at it from both top and bottom.

 

[theKnifeArtist]

ahh tarter sauce. that sucks.
Im gonna have to take a look at that, i hope theres a way around it. maybe a special tool i can make or something.. Two bolts right?

 

[empera]

bring that shit down and we'll do it

 

[theKnifeArtist]

hah, thanks man, but this job is being done on the other side of PA actually, hehe ssshhh

 

[mk3supra]

Oh, I had to change the entire mount where it mounts to block. I thought thats what you were referring to when you said it had the wrong mounts, like the pre 89 mounts.

If you just have to change the rubber part, you might be able to do so without removing the turbo. Yea, its just two nuts you would need to remove.

 

[GrimJack]

Yes, it can be done without removing anything else, I've done it here.

I did have to pull the bit that mounts to the block, though.

 

[theKnifeArtist]

ok this "wrong mount" i was talking about is a solid motor mount. This solid mounted car needs stockers. My bad for the confusion..

Pull the bits...you mean there's a threaded rod in the block? sorry, never really looked at it. Can i use two nuts to back it off?

 

[GrimJack]

No, there's two parts to the motor mount. The mount itself is just a squashed cube with two bolts sticking out of it. It bolts to the subframe on one side, and to a cast aluminum piece on the other side. It's the cast aluminum piece bolts to the block. You'll need to pull the piece off the block as well, or you can't get the mount off.

 

[theKnifeArtist]

So that piece attached to the mount just has to be unbolted off the block. What's the trouble? i guess i need to see pictures to visualize better.

 

[GrimJack]

It's not a problem, I just didn't want to leave everyone with the impression you can pull two nuts per side and it's done. It's actually 2 nuts and ~5 bolts per side.

I did it by just undoing the 2 nuts per mount, but it involved an engine hoist, a pry bar, and a moderate amount of swearing lol. Also, on the pre89 cars, it's not a cast a aluminum mount bracket. It's a welded steel bracket.

Correct, pre '89 cars have a steel engine mount brackets.

i just loosened the nuts on both mounts and the tranny mounts. then i took my floor jack and jacked up the side that needed to be changed. i left the bracket thats bolted to the motor on there. pretty easy. just take a look at it and you can figure it out
