I just had a 2 hour epic battle with the four bolts on the motor mount
The two M8 x 23.5 987496 into the engine had severe corrosion in the boss in the mount. The M12s had severe corrosion in the threads in the subframe, probably because the bottom gets salt exposure.
The rearward ( car orientation ) M12x40 982841 is the real bad boy as access is hindered by the fuel one and axle shaft on the 1999. I managed to get two thread turns up then sprinkled holy water from the PBB church , and still was working full shoulder muscles on a 8 inch wrench
Pictures of the nasty boys to come
They cleaned with a Dremel and pick, and I antiseized them well.
Doing the timing belt job, I noticed with the balancer off, you get a good straight shot down at those nasty M10. With a good six point impact socket I could have made short work on those

View and access looking down during timing job
I cracked these easily with an impact an extension, greased them up, and reinstalled.

Chassis break on this part in 1999
ALTER 2 FC1; S70 CH -565000. FC2; S70 CH-566268, V70 CH -540000. (9209869)(9141257)
You can get a FEBI or Rein aftermarket for about $30 on the earlier part, the later part was Volvo only When I checked in 2019
The M10x 35 in to the block also show a chassis break at engine 1634069. Hmmm, part change but same size!

Re: P80 front motor mount hardware tip 8631698
I'm confused. The four corroded bolts with the new Febi mount look like they're the same size. They all look like M8's to my eyeball.
I think I undid the bolts on this mount that go in the engine and shoved it over a little to get more room when I last did the timing belt on mine. Or maybe I've got that wrong. I've remembered a lot of stuff since then.

M8s go horizontally into the bracket and also from bracket into the block
M10s go vertically through the mount into inserts in the subframe

Re: P80 front motor mount hardware tip 8631698
Are you recommending a preventive maintenance step of removing and apply anti-sieze to these bolts during a timing belt job?

Absolutely. It might be easier on -1998 but 1999- it’s really tight to access these.volvolugnut wrote: ↑Mon Oct 19, 2020 5:29 pm Are you recommending a preventive maintenance step of removing and apply anti-sieze to these bolts during a timing belt job?

I just did this on the Grunhilde build as I had it all apart. It was real easy access with the belt and water pump out. Bolt out, grease up, bolt back in.
