V70: Top Engine Mount Rubber

[steelsurgeon]

I have recently bought a v70 classic 140hp i have noticed that the top engine mount rubber looks like it needs changing i have read a few posts on here about it after having a look under the bonnet it looks as though the piece that holds the rubber bush can be removed from the top of the casing tomake it easier like using a vise to push the new one in etc ANY THOUGHTS WOULD BE APPRECIATED

THANKS

Congrats on the new car - an excellent choice!

Getting the old bush out is easy - just cut it out with a hacksaw. To get another in, basically you've two options:

1. Get a Volvo bush - around about £13. You will need to remove the mount though, and have the new bush pressed in. It potentially more fiddly and pricey.

2. Get a poly bush for around £20. It comes in two halves that you can press home yourself, using a big nut and bolt and a couple of washers. There's loads of posts on here about the relative merits of the various after-market bushes.

I did mine a year or two back using on of the bright purple poly bushes. It is an easy job, and the improvement is noticeable.

Some argue there's a bit more vibration on idle, and possibly that's true, but the palpable instability that goes with a knackered bush vanishes with the polybush, and it is a very easy job to do.

Cheers

you can get OE mount it with some modification, if you take a groove out of the outside of the mount, [the width of a hacsaw blade is perfect] it will slip in and be tighter than a dolphins sphincter

tou will see here on mine at around the 1 o clock position the groove, a mechanic friend of mine gave me the trick, it will last just as long like this and was simple to installl

A shop replaced the torn OE bush on my wife's 1996 850 wgn 170 petrol with 4-spd auto. They used a purple colored poly one and we did not detect any increase in vibration in the pass compartment or on the steering wheel.

If I were installing a new OE Volvo bush I'd put it in the same orientation as the original one. I think that Volvo intended for it to be that way. I think there may be a mark on the steel bushing holder that the arrow on the bush is supposed to line up with.

One reported solution is to put the new OE Volvo bush in the freezer for ~6 hrs or overnight. The frozen Volvo bush will reportedly be reduced enough in diamter so as to slip right into the metal bracket. Then wait 'till it warms up and it will be firmly held when it warms up and expands. (Warning: This might only work with the newer V70s with the aluminium bushing bracket which might have a greater relative expansion than the steel one on the older V70.)

I removed the torn orig bush on my 2004 V70 petrol 170 without removing the bracket from the engine. I first disconnected the two side connectors, swung them out of the way, then reinserted the orig bolt in the metal center of the bush and screwed the nut back on. Next I used a pry bar on the nut against a piece of 2 x 4 wood framing and gently tore the aluminium center out of the old bush. This opened the center of the old bush for cutting radially most of the way through the hard plastic edge with a hacksaw blade. Then I inserted a heavy screwdriver between the hard plastic edge of the bush and the circular metal holder near the cut and cracked the hard plastic rim of the old bush. I could then pull it out with pliers.

I replaced the bush with a rather stiff, symmetrical, two-part poly bush in the circ bush holder and tightened everything back up. I immediately got significantly more vibration at idle on the steering wheel, but this has lessened with time. If I had it to do over, I'd try an OE bush using the freezer method.
