Car Forum / Volvo Cars / January 2007Torx rotors screws stuck on 96 Volvo 850
In trying to replace the distributor cap and rotor I ran into a problem getting the torx screws out that hold the rotor on. They won't budge. I'm pretty sure it's the original rotor on there because it's really worn out so I'm confident that it's causing my gas mileage problem. I tried using a torx rachet socket and a torx screwdriver and they both feel like there are a little too small for the bolts. I'm afraid of stripping the screws if I try too hard. I sprayed some bolt lossener on them but this didn't help. What else can I do? Thanks, Bill > In trying to replace the distributor cap and rotor I ran into a problem > getting the torx screws out that hold the rotor on. They won't budge.

(2)If the screwheads are accessible, it'd be wise time to purchase a tiny, but GOOD pair of vice grips (I have a pair ~3 1/2 inches long made by ViceGrip)--I've used them for such many times over the years. You'll wonder how you ever got by w/out them. s My 98 V70 came with a few Torx screwdrivers in the toolkit. Have you checked around the spare tire to see if the proper size is there? > > In trying to replace the distributor cap and rotor I ran into a problem > > getting the torx screws out that hold the rotor on.

A piece of plumber's putty pressed lightly against the head will show which it is for sure, but I think Glenn already knows :-) Mike In an earlier contribution to this discussion, >> Torx heads come in several different sizes, and you need the correct >> bit to fit a particular one.

However, I've just looked at a photo of a rotor arm in my Haynes 70-series manual, and the screws look distinctly like Allen screws - so I guess the 850 had those too.

That, or Haynes is using the same picture they have used for the last 20 years...... ..........or a generic picture from another car entirely. > Roger Mills <watt.tyler@googlemail.com> wrote in article > <50d60aF1dm1ksU1@mid.individual.net>...

Not that its the same, but i have seen both hex head and torx head caliper pins on taurus of the same vintage. I about got caught using the wrong tool for the job because of this. DOn't know if it was a factory thing or after market parts. It pays to check Bob Volvo uses 'torx' screws??? I have a feeling they are allen head, could be wrong though. Non of the older Volvos I used to own were cursed with torx.

And for that application, are they right hand or left hand threads? Just a thought. I know little or nothing about Volvos... (Friend of mine met an old acquaintance on the plane, who wanted him to come home with him, have a drink,and take a look at his wife's 'Vulva'. Friend was excited until he saw that darn little Swedish car parked in the driveway;>) ((a true story, mostly)) > Volvo uses 'torx' screws??? > > I have a feeling they are allen head, could be wrong though. Non of the > older Volvos I used to own were cursed with torx. I haven't seen them on a Volvo yet, Saabs are full of them though. So long as you have the right bits they're actually great, I have yet to ever strip one out and the screw will usually stay on the end of the bit well enough to feed it into a tight space. > > Volvo uses 'torx' screws??? > > [quoted text clipped - 5 lines] > ever strip one out and the screw will usually stay on the end of the bit > well enough to feed it into a tight space. Jeeps are full of them. The teeth rot on them with the slightest bit of a paint chip so once used, they strip out extremely easily. Same for sizing. The paint thickness won't allow the proper sized bit to fit, so folks use one size too big, the paint just crushes and bingo, another one stripped. So to use them you have to chip the paint out which rots them.... At least they do drill out easily because the hole centers the drill bit nicely...

(Whether they use them in the distributor, I don't know yet, though.) JRE Bill, I take off the cap & rotor every year to clean the points of carbon deposits on my '95 850 an the rotor is held on by 3 mm. Allen head bolts, not torx.

So I figure it might be either, depending on the manufacturer of the rotor. |
