Alloy Timing Wheel fitted

Post by Brucky » Tue Mar 12, 2019 8:53 am

My engine was fitted with a new fibre wheel. When I spoke with the person that rebuilt the engine he considered them a service item! So yesterday a new alloy one was fitted which I got from QRG. It makes a right racket on startup :lol: We tried to do it without removing the sump, but what an awkward bar-steward, we just couldn't get it to seat right, and the sump had to come off.

I am about to change mine ,but have to wait till the weather improves as I work in the street,
Is this a one man job ?
How long will it take me ?
Do I need any special tools to get to my old one off ?
Going to do an oil change as well so may as well drop the sump and clean any crap out
Thanks Richard

For the noise issue, if indeed it is an issue:

Are you using a manual fuel pump?

If you are, then the pump lever might be touching the back of the timing wheel. I had this issue on mine as the pump had a lever was a folder over steel assembly and was too wide.

It was an awful racket though, and obviously wrong, plus creating alloy filings. A new pump with a thinner cast alloy lever resolved this issue.

My alloy timing wheel is actually quite quiet in operation.

Hi Richard,

It is a one man job. I did it with my mechanic as I wanted to learn about my car. It took us (me) about 6hrs but I took my time. I had to remove a few bracing struts/cross members on the Coupe to get decent access. We put a puller into the two opposing holes on the fibre wheel and wound the old fibre wheel off slowly. My engine only has 1000 miles on it so things came apart fairly easily. Taking the sump off also gave me a chance to see a bit of the engine after its recent rebuild, and only speaking personally I wish I had taken the sump off from the get-go as its fiddly. I know for certain that I have a good gasket seals, and no potential future leaks :w . I had a four post lift which made life easy, I am to old and fat to get under the car. A few step-by-step threads are on the site if you do a quick search, which I followed.

Hi Steve,

Its not a manual pump, but thanks for the heads up. I ran the car for 5 min, and it did start to quiet down in that short time. I think it will take a little while to bed in 200 Miles? ish.

I fitted an alloy timing gear and matching steel crank gear 2000 miles ago. It whined to start with, not too unpleasantly, but is now quiet. An easy one man job to change both gears, and I changed the water pump at the same time

It's certainly a one person job. You may get away without dropping the sump, I've done two, once I had to drop the sump, once I didn't. But bear in mind that if you do remove the sump, it's a much easier job than on many cars, as it's a flat joint face and there are few obstructions (eg. no crossmembers), in the way.

Don't be tempted to knock the new wheel onto the camshaft nose with a mallet, use the bolt to wind it on (otherwise you may knock-out the core plug at the back of the block, and turn it into an engine-out job)

My alloy one made a slight noise on first running, but after 100 miles or so it was silent. My steel one was noisy when first fitted, and though quieter, is still noisy after several tens of thousands of miles of vigorous use. I think there's an element of luck with steel ones.

I had heard people say the timing wheel made an awful racket so when i started mine and heard this



this is the sound of the manual pump rubbing on the timing gear
