Engine mount dilemma - WTF?
« on: November 20, 2017, 06:49:15 PM »
Hi guys,
Quick question to see if any of you have had this issue:

I ordered two sets of motor mounts for the ZJ from Omix-Ada - both had fitment issues. (The holes do not align)

The second set they sent were a little better so I put them in.

Now the steering shaft is hitting the motor mount and I cannot turn the steering wheel. WTF? Are all aftermarket mounts this bad?

So the question is:
Do I:
A. Notch the motor mount to clearance the steering shaft?
B. Send the mounts back and try another vendor and company?
C. Reuse the old mounts but press some sort of poly bushing into it and see how that works.

Looking forward to any advice I can get.

thanks.

Omix-ada is crap. Get a different brand

Yeah F those things! One of my first car building lessons I learned the hard way many many moons ago was with bad fitting motor mounts. They made the engine sit crooked and that put too much pressure on the transportation input shaft and blow it. Thankfully tr350s where a dime a dozen back then!

I spoke with Brown Dog last week. They do not make anything for the ZJ due to it's history with alignment issues on their frames. Guess this is why.

They did offer to research a poly bushing for me if I send them the inside diameter of the mounts.

That's why I was asking about pressing daystar or similar poly bushings in.

I have no issue grinding or modifying the mounts. I just don't want to have to take this engine back out for a stupid motor mount problem.
This shouldn't be this hard. I never should have built a ZJ to begin with - but I'm married to this thing after 22 years.

 No, the driver side of the OEM  looks totally shot, rubber wise. I never figured that new motor mounts were going to be such a headache.

As far as the Omix ones, I was able to force the metal to conform around the frame rails with a very large torque wrench, as the original issue was really bad alignment of the new mounts. After a couple of put it in and take it back out sessions, they fit pretty good.

Now the trouble is that the design of the Omix ones are a bit different from stock and one of the mounts has a support bracket the runs right in front of where the steering shaft goes - so in order to use it, I have to notch it to clear the collapsible shaft.

Also, the rubber in the passenger side mount is pretty darn soft. Nothing like the stock ones. I can move it with one finger. I can't imagine what an engine is going to do to it.

But here is the weird thing. The distance between the holes on the ZJ 4.0 block is around 20.5 inches.
The holes in the Omix mounts are exactly 20.5 inches apart as they sit in the frame rails.
And to top it off they are dead nuts levels across the engine bay when you put a straight edge across the bolts.

I am in a serious dilemma as to how to proceed.

So you'd notch the motor mount to clear the shaft and call it a day?

I just want to do this right the first time - I'm running out of funds for this nightmare.

It's very minimal. A grinder should be enough tool to make enough clearance. I just haven't done it yet so that I can return these things if that is the consensus.

I am very concerned about engine height as well, since everything else about these things has been an issue.

I'll post pics tomorrow. If you look closely at the pic I posted, you can see how seriously close that shaft is going to run to that right hand mount. I even went back to the garage and tried resetting the mount to sit further to the passenger side - but no dice.

Tonight, I've packed it in for the evening. Very freakin frustrated.

Hmm, post a pic of where you need to grind. I've always found stuff just isn't simply plug and play.

Also, keep in mind; 22 year-old-rig that you have wheeled, though nothing intense, wheeled none-the-less, the unibody could be tweaked.

Sounds like grinding may be necessary to fit everything.

I’m not familiar with your build. Are you retrofitting an engine?

Did you loosen the mounts on the engine?  I have to do that when I mess with mine to line up.  Once the bolt is in tighten both mounts, engine and frame.

I meant OEM replacements.

On CJ V8s its actually easier to put in the motor mount in with the engine side mount removed, then attach the engine side to the block last.

 If you only need a minimal amount of clearance I'd just grind the mount down where needed...

 It's not a alcohol funny car, it's a Jeep.  The frame side of the engine mount doesn't move (much, if at all) in relation to the steering shaft, so clearance it, paint it and reassemble.

Just fyi.. level does not mean correct. there are alot of applications where the motor mounts are not symetrical

So here is the update on the mounts. The Crown motor mounts came in today and WOW! The difference between them and the Omix units are night and day. The rubber aligns in the mount correctly, they are stiffer by far, they are heavier, thicker and the welds are far better.

Space Shuttle, you are correct on the level thing.  I did a comprehensive test because I wanted to get to the bottom of this and I could not accept that the Omix mounts were my only option. My gut was screaming at me to take them off and send them back - So...

I installed the OEM mounts and measured center to center, measure for level , or not level and then measure the height from the engine bolts to the ground at the lower edge of the level. Then repeated that for each set of mounts and noted the data.

And the numbers proved it out. The Crown mounts sit exactly where the OEM ones did - the numbers were identical in every aspect to OEM when I corrected for the driver's side torn mount. The Omix parts are pure, plain shit quality - STAY AWAY FROM OMIX!!

Pics attached. Crown on top, Omix on bottom.

I even threw a dial caliper on the metal to measure the thickness. The Crown units are thicker too.
