Please give me some help.

I was changing the timing belt on the 740. I was also replacing the cam seal.

When I immobolized the cam gear and removed the pulley, I found that instead of a cast nub in the key of the cam wheel there was just a rolled piece of metal.

In other words, there was a key on the pulley. The key is used to allign the pulley to the cam. But jammed in mine was a little piece of rolled metal. It looked like a spring. Is this what is supposed to be there? There are signs that my cam has rolled 180 degrees off. Wouldn't this totally mess up my timing? Maybe the scratch was there before and it's correct now. But I don't know.

ANYWAY....do I need to replace my entire cam now? Am I totally screwed? Or can I just put a new bolt like piece of metal in there to lock the cam to the pulley?


PLease help!!!!

the pin belongs there, pull the aux gear and see. there's 1 there, also. good luck, chuck.

Ok, now that I've calmed down, I relize it's a roll pin used to key the gear. I spent about an hour earlier, picking out what was left of it from my Cam.

Now the question is where can I get one?

Is it something I can replace with any pin of equal diameter, or is it something special?

Anyone know the part #?


Many thanks....I was panicking earlier.

Roll pins are common, though not in Volvo.


Take whatever bits and pieces you have of the old one to a parts house, NAPA, AutoZone, et al, and they should have one close enough in length and diameter to work for you. Get a spread of sizes, one should be OK. They are cheap.

Good Luck,

Bob

Thanks Bob, that's exactly what I did. After looking on McMaster Carr, I went to NAPA and bought a roll pin or pressure dowel, or whatever. McMaster had the high strength pins, exactly like volvo. They are made from steel rolled over several times. The NAPA ones are only rolled once.

The heavy duty ones have 40% more shear strength.
