FE-FC Holden Discussion Forum

when mounting the hr front, (I bought the rares kit) there isn't a square rubber that goes under the front end itself like on the FC. Do I use the one from an FC and modify?

You can, but you also have to drill out the HR crossmember as well. Better to use the bolts and rubbers out of the HR if you have them.

Ken the bolts I had fitted, I bought the kit it came with the inner and outer insulators but not the square insulator from under xmember. Any ideas where I can source one its not listed at rares.

PS V6 conversions say use engine mount "A1005" is this the 186  engine mount?

It's not the bolts that have to fit through the holes, its the spacers. Check out the size of the holes in the FC crossmember.
A rather lengthy explanation follows :P

FC mounting consists of 3 rubbers and 2 spacers (the various colours & lengths have been discussed on numerous occasions). Suffice to say it is not the easiest thing to put together right, because the principal idea is that the crossmember "floats" between the lower 2 rubbers, but the retaining plate is held firm by the spacers in the middle. Check out figures 3-5 and 3-6 in the workshop manual for a clear picture of how the thing is supposed to work. Torquing the nuts up correctly also takes lots of effort & is fiddly.
If you do not drill out the crossmember the spacers lock on the crossmember and the rubbers are virtually useless. The results will be that road shock and noise is transferred from the crossmember into the body of the car which is undesireable.

HR mounting consists of 2 rubbers and 1 spacer - very easy to put together and now the crossmember simply has a rubber sandwiched between it and the subframe.

You can see why the HR mounting system is desireable, it is much simpler and easily assembled and tightened.
Every HR front end I have put on an FE or FC I have used the HR mounting system.

Answers to your questions;
You probably have to buy the FC kit to get the lower rubber insulator new, or use a second hand one.
I don't know the code A1005 - It may be their own code or maybe a Bursons/Repco code or something else again.

try these but you probably know of them already.

This is the rubber kit (mounting system) that Ken is refering to:

I have installed 2 HR Front Ends into my Ute & Sedan using this kit as per Ken's instructions and it works perfectly.

Yes Trevor that is the kit I bought. Do I use the FC bolts or try and source HR bolts??? YES I am an idiot

The FC bolts are too long - you really need HR bolts

Ken

any one got HR bolts they want to part with

6.008 MEMBER, BOLT, SHIM SPACER, INSULATOR – Front Suspension Cross (cont’d) (Page 387)

Description                                         Part Number
Bolt-Hex.hd. ½”-20x 5”                        126038     (4 of)
Washer- Spring lock ½” – medium          120384     (4 of)
Nut – Hex ½”-20                                120371     ( 4 of)

I think these are the part numbers for the HD HR Cross Member mounting bolts. The parts book is not that easy for me to read. If they were the parts (someone please confirm) could you not buy them from a reputable bolt shop if not available through Rares.

I have assumed the 20 referred to in the description is the height of the head  ???

es they would be available through a bolt shop - the 20 refers to threads per inch - in this case UNF

Ken

Hi Fred,
Have you found any HR front end bolts yet?
These look like the ones you want.    Ebay Item #150733804878


Cheers Stewy   8)

sourced the right bolts from a bolt shop borrowed a sample, thanks for your help everyone

Fred is the above the right description for the bolts?

Regards

Wayne b

Yep - I had a quick look through the parts book and FE up to EJ used a 5 1/2 inch bolt, then EH to HR used the 5 inch bolt as described.

Ken

Thanks Ken. The thread looks about an 1 &1/2 " long.
