Rear bushes

[claypole1360]

Ok, how do you get the rear bushes in the trailing arms without mangling them up in the press? They are uprated harder rubber and keep getting turned back on themselves as they clear the lip of the hole.
Thanks Clayps

The common solution - when you've given up on an impossible task
is to swap them out and fit equally hard polyurethane bushes instead
since they are fitted from both sides (whithout any press, just finger force)... [:D]

Hi Clayps,

I had the same problem and had a few helpful replies to my post,

http://www.forum.triumphtr7.com/topic.a ... ing,bushes

In the end I got a 'sleeve' and put the bush into that and put the sleeve up against the trailing arm, then using a vice and some large sockets pushed the bush from the sleeve into the trailing arm. The sleeve stopped the bush from expanding outwards. (I had a bit of pipe that was just the right size to use as a sleeve.)

Not an easy job and with the trailing arms you have to carry it out 4 times!!!

Cheers, Dave

One of those things, if your going to have to take them out for any reason, put in the poly as it's easy, last longer, better control. There are two basic types. Hard black poly that you typically find from US suppliers and soft(er) poly that you typically find from UK suppliers which comes in orange, blue, yellow and possibly other colours. The hard black is good for racing but too hard for general driving. I have the black up front and coloured in rear. I had black in the rear but found it too rough and it transfered too much differential noise to the interior.

Thanks guys, we are persisting with the tube technique although they are a pig to do. Polyurothane is a bit of a confusing issue, so many people sell them and they range from really expensive to dirt cheap, when S and S suggested these ones at a reasonable price, I jumped at it.
Hohum, perseverance it is.

Well, we lunched one of the bushes trying to put it in (it is a hardened bush after all)so we gave the job to my local trusted mechanic and he has managed to get three of them in the trailing arms but I now have to get another replacement bush as he has also lunched one.
These had better be worth the hassle!

Still not sure if you have poly or not. I thought all poly comes as a two part bush. It's so easy I wouldn't consider any thing else. First you put a slight angle on the stainless metal insert to allow it to slide easier onto second half of the bush.




Then you drill a small hole into one of the bushes so it allows the air to esacpe when you push the bushes together (one from each side.





Then you push the bushes in from each side and use a vise to compress the last little bit so it slides nicely into the bracket on the body/axle.

Apart from the drilled hole - my view exactly.

And with all the pro's for polyurethane as compared to rubber based elastomers
I personally would never go another route as long as a poly version is to be had.
Poly is:
usually much easier to fit
by virtue of its chemistry impervious to ozone, petrol, grease and oil(s)
usually fitted with a stainless insert tube
usually nicely coloured (which is a bonus when looking at the finally finished restoration you've accomplished)
usually more costly

Rubber is:
none of the above, especially that last line.
(But if it gets soaked in oil or petrol or ozone - or time - it will need to be prematurely changed out,
long before the polyurethane version would.) YMMV of course. [:D]
I know lots of people who prefer rubber "because that's what British Leyland, or whatever, specified"...

Yep, they are hardened rubber bushes, they were initially cheap and for the ammount of mileage my car will do, mainly dry and a spot of hillclimbing/sprinting, they should last well.
That said, I hope I have saved enough moolah to buy proper poly bushes by the time these wear out as I am still recovering from the hit of buying a house and having two other Triumphs requiring "work",

Well thanks for the help guys, I have my bushes fitted, I took them to the chap who does my MOT test. Picked them up today and am still reeling from not being charged for the work. He made me promise not to reveal his name because it would be bad for business[:D].
He is armed with a massive hydraulic press and all the associate tubes and compression tubes.

It sort of reaffirms my faith in humanity.

That said, as he does the MOT on the TR, he may well have ended up fitting them after the failure anyway!!!

I had a set of Triumphtune hardened rubber bushes on my rear suspension for over 20 years. Limited mileage maybe, but most of them were under V8 power............

I think they'll last a while.

I put the uprated Triumph tune bushes in my first TR7 many moons ago and they were fine even with high mileages.
I hadn't even heard of poly bushes at that time.
But it seems that current rubber bushes have a much shorter life expectancy [B)]

Glad to hear there's real progress Calvin.

Mine got taxed last week, and I'm working my way around the issues (there seem to be more now than there were when it went into the garage last winter).

Hope both 7s can catch up soon!

Hi Simon, if not a sunday cafe meet then certainly the open weekend, hopefully with a confident 7 v8, cheers Clayps

If you put the poly bushing in first with grease, then bevel one end of the metal bushing, you can push it into place beveled end first.
