Walkinshaw Toothed Supercharger Belts ( 2 Belts on back )
Discussion
Evening All,
Question:- Will driving my car without the belts on the back of the supercharger do any damage ?
Basically been out for a drive today,in & about around blackpool and back home and not spirited in the least (Had the family in the car)
Just coming out of Blackpool town centre and car didn't feel to right, in terms of power. The short story is I pulled over only to find both toothed HI Boost belts had come off, the back of the supercharger. They are in one piece but worse for wear and not reuseable. (They were only fitted 10 months ago/7000 miles)
From my small test of looking at the 1 belt original, and it's size, compared to the 2 new toothed belts in it's place, the 2 smaller toothed belts take up more room on the pulley, and the tensioner pulley ran over the top of the two belts leaving wear on the outer edges, could this be the reason they came off ?
So any ideas what I should try to do next, very much welcome.
Here are pictures of the belts
This one shows the original belt height vs the two belts height, as you can clearly see the 2 belts stack higher than the original.
This picture shows how the 2 belts were sitting beside each other, and note how the outer edges how worn marks in them. (From been cut/worn against the tension pulley, as the belts are wider than, the pulleys guide)
This is a close up of the outer edges on both belts
This shows the worst belt damage. ( I think this belt slipped under the other belt )
So can you get one belt that is the correct size, to do the job ?
Belts are just belts, quite generic in most cases.
Does seem a bit crazy they'd place two belts like that side by side. It was bound to fail prematurely.
Contact the likes or Erik's or Hayley Bearings.
They should be able to get you a belt the correct size. You'd need to tell them the length you need and tooth pitch, and of course width.
Maybe best if you can call into one of their dealers with the original belt and hopefully it will still have some numbers on it.
Are there any markings on either of the two toothed belts ?

Yes I have found the belts that were used, and the original belt has all it's markings clearly on it.
The 2 belts are 450-5M-15 Timing BeltThe Medway HTP (High Torque Power) timing belt (synchronous) has a curved tooth profile providing a positive drive by the meshing of belt teeth with the grooves of a relating timing belt pulley.

That'll be 450mm long, 5M tooth pitch and 15mm wide.
So if you wanted double width, that would be 30mm wide
ie 450-5M-30
Hayley will be able to get you that cut in any width you want from a sleeve with the Gates GT3 profile ( or GT2 etc )
Erik's seem to use Fenner, their equivalent is the Torque Drive Plus.
They'll all pretty much use the same part number structure, and likewise Erik's will have them cut from a sleeve any width you want.
The belts I was using for a while with my blower were 1600mm 8M 50 and cost around £60-70 each.
Erik's were slightly dearer than Hayley bearings.
But basically anywhere that specialises in bearings or belt drive systems will be able to get you the belts.
There are other brands I'm sure too.

Interesting to note the original belt was 457mm and the other two are 450mm.
Thanks for the information, I have Gates PDF up with all the details and designs.
