See the forum member comment about MTC.

iPd has the MTC version:

Amazon sells the MTC version.

Amazon sells this from brand name Hamburg-Technic. Appears better than an MTC.

See the comment about Hamburg-Technic.

FCP sells this from Corteco(?). Looks like MTC:

The assembly is pressed together. Probably when rather warm.



Volvo Genuine Classic Parts in the 240 catalogue, lists two harmoic oscillator crank pulleys for B230/B200:

For all redblock 4-cylinder models, we have two different dampening crank pulleys?

Up to 1992 is Volvo PN 3514089-6.


1993- is PN 3507751-0 (tasca calls this an intermediate cam t-belt gear)

The final 1997 GCP 940 catalogue lists PN 9135194-0. NLA says Tasca and Volvo part webstore. GCP parts are warehoused in Sweden.

Yet at Tasca and aftermarket elsewhere is PN 9135194.



Doubtful you want this on your driver daily:

I've grabbed spare harmonic oscillator crank pulleys from salvage yards.

On my 1991 kittys grey Volvo 240, I installed a new Volvo blue box crank pulley maybe a decade ago. With freely spinning alternator, (non working) AC pulley, and power steering, with headlights on, there is a screech. The alternator, AC, and power steering accessory belts show proper deflection tension when pressed with a thumb. Screeeeeeeeeeech.

Owning these cars continues to be less and less fun. No fun in the prior 20 years anyhoo.

Fabulous Volvo and there crappy documentation, part number method, and terrible documentation.

cheers,

dud.
