Cheers all.

I have a pair of Engine Mounts and Insulators from a 2004 HZJ79 that had 2200 hours logged. I have checked toyodiy and they are compatible across all 70 series platforms.

I am looking for 80 series of the same items if anyone can source them, or want to trade, if you are lucky to be building a 7X....:grinpimp:

$120?

Chris, since you have so much more experience than i do, it would silly of me to assume you are incorrect. And although part numbers are not definitive for fitment, the iron mount numbers are different for 70 & 80

12311 BRACKET, ENGINE MOUNTING, FRONT NO.1 RH
12311‑17021 1H*..HDJ7*, HZJ7* 1 $108.85
12315 BRACKET, ENGINE MOUNTING, FRONT NO.1 LH
12315‑17021 1H*..HDJ7*, HZJ7* 1 $108.85

12311 BRACKET, ENGINE MOUNTING, FRONT NO.1 RH
12311‑17010 1HDT, 1HZ..HDJ80, HZJ80 1 $109.79
12315 BRACKET, ENGINE MOUNTING, FRONT NO.1 LH
12315‑17010 1HDT, 1HZ..HDJ80, HZJ80

I've mocked up the mounts together on the frame, but the opening created by them, doesn't sit center of the body, or center where the gearbox sits, and therefore, the crank isn't centered. Please correct me if i am wrong. I've checked that the crank is center with the block, if the space created by the mounts isn't centered, then the block has to be shifted to one side of crank more than the other. Sorry for using 'center' so many times........

The engine does not sit center to the body or the frame. The long mount goes on the passenger(right) and the short mount goes on the left.

No idea what year 80 you are working on. If its 93-94 the engine will drop in . If its a 3F 80 you will need to make your own mounts anyway so the mounts used are less relevant.

Your best bet is to mock up your engine and trans fit by relating the outputs of the transfer case to the flanges on the front/ rear pinion as well as the cooling fan to the radiator and a stock diesel fan shroud, not by trying locate the engine in the center .
 
Thats the problem, an engine mock up isn't possible due to current space.

You have me questioning my measurements now, as i did it the middle of last year. I know the iron mounts are 35 degrees from horizontal, or 55 from vertical/block side. The surfaces on the block where the mounts are bolted to, are parallel to each other. However, when i mocked up the iron mount and insulators to the frame mount, one isn't vertical, and leans towards the other mount, which means the iron piece will have to be less than 55 degrees to reach vertical.

Looking bird's eye view, the mounts don't line up, they are 3.5inches apart, so my 97's frame mounts are correct.

I am going to the garage where all my stuff is at to double check tomorrow, but most likely the mounts will be yours.

My guess is you mocked up the mounts on the wrong side when you matched up to the frame. The mounts do have a different angle from side to side and the frame side mounts (at least on a 94) do as well. I am 100% certain that I used the same mounts as what you have pictured.

Maybe the locating pins on the mount are in a different position since those are 70 series isolators? There should be a pin next to the mounting stud that is supposed to line up with a hole in the frame mount as well as one one the engine side. Was the pin in the way when you held it in place?

Good luck
 
Well there is a "L" and "R" stamped on the iron mounts. Also, the bolt pattern to the block is different for each side's iron mounts, so unless that day i did the mock up was opposite day :D, certain i didn't mess up. Oh, actually, i did swap sides, but the setup that looked correct was actually reversed (respective of the block bolt pattern). Plus, that right, the passenger side's iron mounts is longer, and thats the side that is off angle.

The surfaces of the insulator where the pins are connected to, engine side and frame side, as long as those surfaces are parallel between the 70 & 80 insulators, the angle where the iron mount meets the block shouldn't change.

Sorry fellas, this is turning into a compatiblity thread.....

Pictures coming tomorrow........

Maybe this thread should be moved.

For one thing the bolt pattern on those iron mounts you pictured is the same for the block side. You can actually swap them side to side.
Second. The block mount surface where the iron mount bolts to the block is parallel on between each side. Its the same hole pattern on all the HZ/HD/HD-FT etc.

I have a set of much later mounts from an FTE engine and they are the same length and angle on the insulator end as every other set of HZ/HD mounts I have had. The angle is different between the left and right just like all other mounts I have seen (70 and 80 series). The difference with the FTE mounts is that the short side uses the wider mounting holes in the block (which exist in the earlier blocks as well).

If you are finding that the passenger side appears to be the right length and the angle is off then you will most likely need to create your own frame mount or at a minimum make a wedge to correct the angle on the frame side of the insulator.
