It's on a P reg 1996, Volvo 850 S, with the 5 cyl 2.4l engine.
I was driving home when I started to get a real bad misfire then it spluttered and stalled, got the AA out and after a while of checking spark plugs (Nº1 was firing), master lead (also nice healthy spark) etc. he finally removed the Distributor Cap and the rotor arm fell out in several pieces!
When he checked it he noticed the bolt that went into the end of the Cam was broken.
I can't afford to take it to a garage (would cost more than the car worth!) so wanted to try and do the work myself, so got a guy at work to knock me up a Drill guide to sit in where the Distributor cap fits and have drilled a centre pilot hole through the end of the bolt.
My question is What should the end of that bolt look like? I can't find any pictures of one in the internet and can't find any technical specs as to what size thread it would be (if indeed it's even a threaded bolt?)
Been looking on the net and it keeps showing a Rotor Arm with three screws on it as the one for my car? The AA man took the old one away so I couldn't see it. There's no where to screw them in so how does this work?
Can someone help? I don't want to drill it to 10mm to tap it out then find out it's a 9mm bolt! or that it's part of the cam I'm drilling!
I don't have a driveway or garage to work in so can't strip the engine ad remove the Cam, plus I wouldn't feel confident enough about resetting the cam cog/belts, timing etc.
Some pics of the cam end before drilling pilot hole, I'll try and get some new ones tomorrow.
Any help would be much appreciated!
Many Thanks
Luke.
