Re: CAM pulley markings

I have new CAM pulleys and noticed the alignment dots are not aligned. One is half a tooth out. Are these purely a visual aid and it's the keyway that does all the important stuff? Where did you buy the pulleys? A friend recently purchased similar looking pulleys from (?) either SJ Sportscars, or L...

Re: Another timing belt question

In people's experience, once the timing belt tension is set how many miles does it stay within spec? Pete, A little redundant to my first long reply, but... Getting back to your original question, if you use a Gates Racing Blue belt, either trapezoidal or HTD, it's very likely that you'll never hav...

Re: Another timing belt question

I feel that is sound advice. The 2 year rule was based (I feel) on old technology. Modern materials makes belts today far superior. I have just changed my belt after 5 years in situ. And I do above average miles for an Excel owner. Most will scoff at my insanity but the old belt was like new still....

Re: Another timing belt question

Pete, The 907's design work started in the late 1960s. While it wasn't the first engine to use a timing belt, it was very early in the belt industry's learning curve. In hindsight, some things should have been done differently, especially the belt's path round the engine. Especially the placement an...

Re: Another timing belt question

The black belt tension evolved through the years, and finally settled on 95 Burroughs. Consider 90 as a minimum due to belt stretch over time, and time to re-tension the belt. Don't let the tenson go below 90. If you tension a new black belt to 95, "initial stretch" will cause the tension to drop of...

Re: Borroughs gauge for sale.

Actually, thinking about it, for the mechanical gauge they are both the same setting, it's different settings if using the resonant frequency method. Sorry, I'm late to this thread... Yes, when using a Borroughs gauge, use the same '95' tension for both the trapezoidal and HTD round tooth BLACK bel...

I'll just give a simple "no" to this!
Right on.
It's either remove the engine & transmission from the car, or
remove the car from the engine & transmission.
The choice is yours.

Re: Gearbox Rebuild

Richard,
In message #5, there are 3 images that failed to upload. At least I can't view them, but all other images show up. Is there something in those photos that is worth an effort to try posting them again.

I wouldn't doubt that she had more than one. Colin certainly did. One of the benefits of being in charge.

Re: Where Can I find the Engine Number???

Brian,
I don't know what's going on with the engine having two numbers... unless, of course, that has something to do with being the original development 912HC engine. Do look into that with Lotus and let us know the story.

Re: Cambelt Pulley Wear

The tensioner bearing got lost in all the pulley load debate... how long and how many miles has the bearing been in service? The rule of thumb is that the bearing should be replaced with every other belt change, presuming the car gets driven to the limits of the prescribed service intervals. Or, rep...

Re: Is this the last Excel?

I do not believe it to be the last car by chassis number but it might have been the last car signed off. More to that point... The "Build Date" incorporated into the VIN number, and stamped on various number plates was the date the paperwork was 'pulled' to start the build process. No car existed t...

Re: Where Can I find the Engine Number???

Brian, The Excel was never sold in North America, so I'm on this forum because I have two Eclats. Lotus did touch the world, so ask a question on the internet, and answers could come from anywhere. You're playing in a larger pool than the puddle in your driveway. Winters here do tend to be cold, sno...
