A big thankyou to everyone who offered help :D
I sorted it this morning!

It turned out to be the 125 tooth belt that I needed.

I hadn't realised quite how tight it fits, and thought that the belt that I had bought was too short, coupled with a bad count of the teeth on the existing belt!

Thanks ...

Blueline...
Hmm, mine has a blue coachline down each side. Does that count?

By the way, as I'm new to Volvo ownership, what do "Snowcap", "Redline" and "Blueline" refer to?

Many thanks, to each and all of you!

All help is greatly appreciated.

Adam,
No, the log book says DL.
My alternator is driven by a separate belt altogether! This runs from the crankshaft pulley to the alternator, via an idler, but is fitted after the camshaft drivebelt, which runs from a much smaller crankshaft pulley.

Adam, just a though, following your comment about DLs being 1.4....
Could it be that mine is not "standard"? How could I check?

Hi Adam,
No, no power steering mod/conversion. I'm darned sure of that, the steering is definitely manual! My biceps can testify to that! :lol:
Interesting idea, 440/460 engine parts. I'll look into that avenue of exploration....
However, I've just been to Ultra-Parts web-site, and they still quote ...

Hi Adam,

No, no power steering, or any other "bells and whistles"! It's a 340DL, 1991, 5 doors, manual, with B172K engine.

Hi Steve, ta for quick response.
I tried Johnsons, on a Saturday as that's the only day I'm not at work, but their spares guy "hasn't come in today".
I live in Solihull Lodge, so Henley is quite close.
I also tried the Volve spares guy in Stoney Lane, but he came up with the same 125 teeth!
My local ...

I have a 1991 340 DL, with B172K engine, and 106,000 miles.
I want to replace the camshaft drivebelt, but cannot find the correct replacement part! :?
The Volvo dealers, etc, here in Birmingham, UK, say a 125 tooth belt is correct, but they are too short! The one on the car has 133 teeth, or ...

106010 miles currently.
1991 340 DL 1.7.
Replaced brake pads and shoes, repaired exhaust down-pipe by welding, sorted right-side headlamp wiper by opening the motor and re-seating the rectifier disc. Replaced distributor cap with one from scrapped 440, including HT leads, for £5.
Car runs well ...
