What are my options: cam timing belt and cogs replacement?

I think there is another fchatter here that has made some.
Unfortunately we are currently out of stock on that item.
I'll add my two cents here, do some homework on how the pullies are MFG. As an engineer and due to legal reasons here in the USA we use hob stock that is MFG with hobs that are licensed from Gates for the modern tooth profile. Anything else is a risk, how much of one? Hard to say, premature wear, loose tolerances etc.. just something worth noting.

 

Doug, I have a few sets left of the adjustable round tooth (HTD) pulleys. Check in the for sale section or search cam pulleys for photos and discussions. I also have a couple of sets of the original square tooth adjustable pulleys that I got back from people who switched to round tooth.

The original Uniroyal patent on HTD synchronous drives expired a few years ago so Gates made slight changes and patented their GT2 drive. They made it backwards compatible so they could sell GT2 belts to the installed base of HTD pulleys. Anyone can make HTD pulleys (and everyone does.) My HTD pulleys can use both the GT2 belts, like the Gates racing belts, or any other make/type of 8mm HTD belt (Gates, Contitech, Dayco, etc.)

 

It says on the advert: Gates T201RB or 5352XS (2V) or T288RB or 5441XS (QV, 328). There are lots of other part numbers but those are a start.
