[E-Type] IRS Cage Installation

I removed the Independent Rear Suspension assembly and replaced
bearings, seals and brakes. I also replaced the IRS mounts with
seemingly identical mounts from XK’s. (one was broken) I am now
unable to get the bolt holes in the new mounts to align with the
corresponding holes in the body. It’s as though the mounts need to
be compressed in order to align. Is this a common problem? Is
there an established technique to solve it?–

All the bolts need to be loose enough that you can wiggle the mounts. That way you can lign them up.

When I put my IRS into the tub, after reading some stuff on
here, I loosely bolted up the rear mounting blocks to the
car, and loosely affixed the front blocks to the IRS. I then
offered it up to the tub using a motor cycle lift. To get
all the bolts in I had to use a tapered pry in the hole to
get full alignment for the bolt to slide in. I also needed a
jack under the radius arm to get it high enough up to the
mount for bolt to be inserted.–

This is an area where a ‘drift pin’ is invaluable. In fact, an old, large screwdriver works just fine. Use the drift pin to help position bolt holes then fit the bolt loosely, as Lloyd recommends.

In reply to a message from etype63 sent Wed 22 Dec 2010:

The first time I did mine, with new mounts, I thought I
would never get things lined up. As others have pointed
out, use of drift pins are invaluable. Since that time I
have dropped the IRS 3 more times. It was much easier the
2nd time. Probably due to experience but I also suspect
some subtle realignment of the mounts occurred as I drove
the car. As others have said, leave all bolts loose but,
that said, they are a pretty tight fit through the holes so
I don’t know if that buys you much. I pre-attach the mounts
to the body and the follow up with the attachment to the
cage. On mine, the rearward holes seem to line up best,
first. Once I make these bolts, I shift my jack to put more
force on the front of the cage and jam it upward until the
front mounts are close enough to start a small drift pin.
Then I go to the adjacent hole, and drive a pin that centers
that hole, then pull the small pin, insert a bolt, then pull
the big pin and insert the final bolt.

I also had to put a come-along from the bottom of the IRS
cage way forward to the front axle area and pull like hell
to get the radius arm mounts to line up.–

Thanks for the advice from all. I also found that the rear mounts
had to be installed on the body and the fronts on the IRS. Even
loose bolts did not provide enough play, however, to get a tapered
pry into the holes. The 5/16’’ holes are 3/8’’+ from aligning. A
jack under the IRS and a 300 lb guy in the car still aren’t enough
to get a pry into the holes. I even tried greasing the ramp.–

Hello John - it is a while since I reattached an IRS but, with
a bit of luck, I will be faced with the same task sometime
soon.

Just a question - does the hole spacing on your new mounts
match with the old broken one?–

A few of mine didn’t line-up so I took it for a gentle drive and
that soon got everything in the right place!–

In reply to a message from David Lacey sent Thu 23 Dec 2010:

I am trying to re-install the suspension cage after buying new
rubber mounts. It is an impossible task as holes for horizontal
pins do no align. And it was already difficult to get the cage
through the mounting screws (had to cut them about 4 mm so they
have the lenght of the original ones)!

However I discovered that the original mounts have 72 mm from the
base of the screw (plate) to the top of the mount while the new
ones (supplied through a known JAguar specialist but made in India)
are 82 m high .

The 10 mm difference does not allow mounts and IRS holes to align !
So now I am faced with:

  1. using the original ones, ‘fixing’ them somehow: one had the
    rubber detached from the metal V. This will make fitting
    straightforward.

  2. Buy some ‘improved methalastic’ ones whose measure above is 77
    mm and hope I will be able to align the holes.

In conclusion: MAKE IT SURE THAT THE HEIGHT OF YOUR NEW MOUNTS (as
measured above) IS NOT MUCH MORE THAN 72mm !!!

If you have other hints please let me know.

Are you using the procedure described in the manual? Because
otherwise you won’t get it on.

You need to have two of the mounts fitted on the cage and
two on the body, then it goes on easily.–

…and since you’ve changed them…
all 4 probably have to be bolted on loosely so they can move around.

In reply to a message from Clive Wilkinson sent Thu 16 Jun 2011:

When Clive says ‘‘goes on easily’’ he means ‘‘goes on eventually with
a lot of grunting and moving the jack around until you can get the
holes to line up’’. This are not metal pieces and so the rubber has
to be manhandled into place. Get a pointy metal drift that you can
use to finally align the holes. Not all that hard if you use the
factory procedure, but you may have a few broken fingernails
afterward.

On an E Type, at any rate – you are doing an XJ6? Maybe somebody
on that forum will have ideas that directly relate to that
situation.

Your description of the measurements does not get across to me.
Specifically what is ‘‘top of the mount’’?

Please post a photo to clarify. You may be pointing out a
