Just out of curiosity, when/why would you replace this part? I'm about to take out my H55f, should I be replacing this while I'm in there?
 
unless it is separating, or very old and never been replaced, I wouldn't worry about it
 
Thanks for the replies. I'll check it out once I have the tranny out. I'm thinking it might soft given there's been what looks like a rear main seal leak for a while.
 
easy way to check if it is separating is before taking it apart, use a floor jack and jack up on the transfer case and see if the isolator seperates
 
Well, my situation is I am replacing the original 4 speed and transfer case with the H55F and split transfer case. I just ordered an aftermarket crossmember from BTB/manager and it is in a FJ60/62 series frame. They sell the isolator, but it is more than the crossmember and brackets. There part number needs a cross reference.
 
the isolator doesn't matter whether it is on a 4 or 5 speed. the difference is how it mounts to the crossmember
OEM had 2 versions of the crossmember, I saw in other posts your questions on crossmembers.
you need to know which crossmember you have or are using that will determine which isolator you need.
 
I ordered a generic crossmember from BTB that is for 60 series frames and will have to modify it for my FJ40. I did not order there isolator because it was more than the crossmember. I will get it from Valle Hybreds it was the best price I found.

old thread, but ive got a similar situation. 1982 troopy with a h55f that needs a new mount. the PO did the swap and having a hard time getting a hold of him, so I dont know what the cross member is at the moment. the current mount looks like the hj47/early 60 mount you have pictured above. the bottom one. Im willing to bet that is it, but is there a way to confirm? measurements, markings?
 
also, for after market mounts, who do you suggest if you cant find OEM? with my isuzu after market mounts didnt last a month.

Photo?

Also.. given a conversion has been done, its anybody's guess.. I have seen a Troopy that went from 2F to a 2H/H55F that required the 2F mount..
 
heres a pic, but I actually heard back! he said it was the original hj47 4 speed crossmember. so which do I need? heres a pic of whats in there now. has a big H on the right side rubber.

You have the bottom mount which is shaped like a "V".

I understand the bottom is a V, but there are multiple v bottom `mounts. I need to know which V shaped one I need. like that one that @duncanrm posted. is that gonna work? cause the hj47 never came with an h55f, so I need the confirmation from Duncan :) got a homie in OZ thats ready to send me what I need as soon as I got a part number confirmation :)
