For the trapezoidal tooth belt, the blue Gates Racing belt part number is T104RB. They are slightly narrower (as are the later Esprit's Gates belts) but they work well.

For the eccentric type tensioner bearing, a good brand Flennor FS03299

 

 

Didn’t realise you can get hold of the blue belt in trapezoidal. 

I also am changing to essentric tensioner. I’m doing all this in the name of reliability. Hoping my faith is not misplaced.😎✌️😮

Changing to the eccentric tensioner from the spring one involves drilling and tapping a hole in the block for the tensioner bolt which is a bit drastic. It would need to be drilled exactly square onto the block face.

The very first versions of the 907 which were supplied to Jensen had the eccentric tensioner I believe and the belts would jump teeth, so they had to quickly design the spring one and add two belt snubbers.

I am assuming (could be wrong) that the reason they went back to the eccentric tensioner was because the round tooth belts are less critical on tension.

I didnt either. The pictures of this belt on the Gates site all show round tooth but the pictures on the Lotustalk link clearly show the trapezoidal teeth and the part number on the belt.

So this is very interesting. Off topic it would be a huge bonus to us Ferrari V8 owners if Gates make a blue belt which fits those, the tooth profile is the same but they are shorter belts. Unfortunately the data on the Gates site is pretty much non existent. I will be in contact with them though!

 

Edit:

I received a very rapid reply to my email to Gates:

"

Hello – we are not authorized to provide that information because there are too many variables involved and we cannot risk a failed engine event.

 

Sorry for any inconvenience "

Given a cost of £500 for a belt change with standard belt, and the blue belt being c£100 more, in theory, even if it only pushed out the interval by 5 months it would be worth if financially (£250/yr on standard), so pushing to 3yrs or more using blue belt seems like an easy choice to make, let alone if you go to 4 years or more.

Against the run of views on this, my (standard) belt normally gets changed every 4 years and has been fine on that frequency for decades.  The car goes in for service and MOT together once a year and follows the specified A B A C schedule - so a C (and belt change) every 4th year.  Obviously twice a long as recommended, but I only do 1 to 2k miles a year... sometimes less! 

Having said that .... the last belt has moved on the pulley and rubbed on the guide fraying the edge so will be changed again after only a few hundred miles.  Hopefully after we work out why it happened....since it never has before.

£500 seems a lot to pay for a cam belt change. I reckon @Sparkydoes the job cheaper than that.

At £495 - you are spot on @Sparky is indeed significantly cheaper than any of the specialists. And he’s more special 👍

I do 5 years on the Esprit and F328 (same types of belts on both).

The mileage is so low that there wont be any belt wear so its only down to the life of the rubber.
