Replacing top motor mount [850][97]... posted by Dave  on Wednesday, 14 March 2001, at 4:47 p.m.
 

                      The rubber in my top (upper?) motor mount is kaput. Local dealer wants $100 for parts/labor, $12 for
                      just parts. I like the second option.

                      Anyone have any experience replacing this? Any tips before I dive in?

                      Am I going to need to support the engine in any way, or is this part just to dampen vibration and not a
                      structural member?

                      Any help is appreciated...

                      that is good price... I just replace mine 2 months ago it was not that hard
                      to remove the bushing... all you do is just hack saw the bushing out

                      Hard part is to press in the new on extremly difficult...
                      you can not press it in it a tight fit...

                      My friend come up with a idea ..

                      2 round plate like a big washer one on each side..little bigger than the bushing itself.. over side..
                      and in center off that big washer we have a long rod with threat

                      we put 2 nuts one on each end..

                      Item that you need:

                      1. 2 big over side plate with hole in the center
                      2. 2 nuts
                      3. Long rod about 12 inch

                      So now the new bushing is in the center and lining up with bracket...
                      and 2 big washer sandwich them together...

                      as you tight the nut on one end this will compress the new bushing into place..

                      The more you turn the nut on the rod the bushing will go into place..

                      it take me 4 hours I can not get the new bushing in place..

                      With this new idea I install it less than 10 minutes...

                      My english is poor hope this will help..

                      Yes you can do it yourself...

                      Great - thanks!

                      I knew someone out there had some good tips.

                      Your english is pretty good too

                      Hey Dave,

                      I have had good luck with the IPD replacement for the top motor mount.

                      I had gone thru oem volvo parts in less than 47,000 miles.

                      The IPD part is very simple to install and hopefully will last much longer.

                      Good Luck !

850 Top Motor mount[850][95]   [post reply]

 I need to replace the top motor mount, not much of it left. Can I hurt anything by driving the car ?
 Recommendations in replacements ? Does anyone know if the aftermarket urethane mounts are any
 good ? Where to purchase same ? Thanks

 Part I think cost $16.00 at dealer...

 driving the car as it is I don't think it will hurt any thing....
 all 850 seem to have a same problem weak mounted.

 To replace it use a hack saw and cut out the old bushing...

 hard part is to press in the new one...

 If you need detail how to do it let me know I just done mine 6 months ago....

 good luck...

 KG- the "poly" should not break; so put it and forget it. Now, the easiest way is to use a chisel and
 hammer to hit out the old mount. I started to saw it out but realised I had to saw in 2-3 different spots and
 it is very messy. all that rubbber all over my engine was not good; with the chisel it was out in 2 mins. then
 you just push in the new 2-piece set up.Note: it will not fit perfect until you insert the bolt and start to
 thighten.
 PS-use a vice-grip and socket wrench to make removal and install eaiser.
 Oh, I paid $20 for mine from easternaerospace.com;IPD is about the same.
 good luck,BD

 From what I've read on this board about the polyurethane engine bushings, they transmit more engine
 vibration to the cabin.

 Yes, the polyurethane bushings shuld last longer, but be prepared for an increase in engine vibration in
 the engine compartment.

 To be totally honest, besides longevity, I don't see why someone would want to replace the stock rubber
 bushing with a polyurethane bushing for the engine mount. Yes, on suspension parts, it will make a
 difference in steering feel, but on a part set more for isolation over connectedness, I don't think it's the
 greatest idea.

 Think about it, your car is 6 years old now. Isn't 6 six years long enough? My engine mount is 7 years old,
 and not a single crack is visible.

 I agree with Sin, there really is no benefit to getting a poly engine mount as opposed to the Volvo-issue
 rubber one. I've heard similar complaints concerning the IPD poly bushing as well. For the record, my top
 bushing is 6 years old and is still holding up well, just a minor crack but no noticeable play or slop in the
 bushing when the engine is running. This is in contrast to my friend's 1998 S70 T5, his rubber mount was
 completely ripped apart and the whole steel arm wobbled like a guitar string! I'd stick with the Volvo
 bushing and leave it at that.

 Thanks, I'll go with the OEM rubber mount. - KG

 FWIW - I don't know about you all, but I'm trying the IPD bushing this time. In the last 4 years this is the
 3rd time the stock Volvo bushing has broken. It is cracked all the way through and I can wiggle the entire
 mount. And that was Volvo replacing it, so it should have been a genuine Volvo part. I hope I don't feel
 too much vibration from inside...

 After going thru 2 oem bushings in less than 50k miles I installed the IPD mount.

 2 years later - no problems and no noticeable vibration to my 1995 850 Turbo.

 Some of you guys have gone through 2 or 3 top mounts which is kind of odd to me. My friend's S70
 mount lasted about 80,000 kms. before it started to break whereas mine is still fine with almost 100,000
 kms. Maybe you guys should check into some of the other mounts for the engine, perhaps those are
 weak and/or broken as well causing you to go through top mounts like crazy. Just a thought...

 Old one came out quickly. I've spent about an hour trying to get the new one in - maybe this is why many
 choose to use the two piece mounts. Anyway I've attempted to rig a press with a long bolt but the mount
 keeps tilting to one side as I tighten it down. Any suggestions ? Thanks, Kevin

 We just did this job on my son's car. I used a threaded rod and for the washers, used a couple of
 threaded pipe flanges, normally used to mount the end of a pipe to a surface, ( one for each end) which
 had enough clearance to allow the protruding center of the rubber bushing to fit in the recess in the flange
 and the flange was able to apply pressure directly on the edge of the bushing. Lubricated with soapy
 water, and it self straightened as it went in past the slight taper on the bushing. With this setup, we were
 able to get the far side flush with the bushing holder, and not beyond as it was originally, but there is
 enough flexibility in the design that it functions perfectly.

 Thanks the threaded pipe flange worked great. Took five minutes. My first 'press' was a real Rube
 Goldberg. Thanks again - Kevin
