Excellent!! I have taken on the post of 1850 Registrar so i have added your car to my database, and if you would like anything 1850 related popped into Dolly Mixture please get in touch.

Keep up the good work.

Kind Regards

Russell.

Fantastic thats great thank you.

ITS A RUNNER!!!!

Been totally run off my feet with work for the last 3 months so hadnt been able to do a thing with the car finally got the gearbox back in the car and with everything crossed started her up for the first time since June.

Noise issue was much quieter and after warm up disappeared altogether thankfully!

Have now bitten the bullet and booked her in on 30th December at the bodyshop for the following works to be done in January:

Replace near side rear wing full skin.
Repair hole at top of rear near side inner wheel arch.
Repair hole in rear off side inner wheel arch.
Repair off side lower rear wing with club repair panel.
Make good on minor dents imperfections all over body.
Respray woohoo!
New roof lining

Then have the huge battle remembering what goes where to.put it back together!

Shouldnt have got carried away. Noise is still there and remains until fully warmed up then completly vanishes. Tried reswapping the starter motor again back to the original unit but no real difference if anything slightly worse.

Truelly scratching at straws over this noise now. Current best guess is a clearance issue on the starter and wether to use the spacer or not or try shims on top of the spacer getting fed up with it a bit to be honest. Gearbox has been refitted twice now no obvious faulty points of bad contact with the fywheel clutch etc. Everyone whose heard it in the flesh has been mystified Mechanics included.

Sorry to hear this Rob.

Given that we have eliminated box and overdrive now its time to look elsewhere...

Time for another video maybe?

Thanks Jon
appreciate your support.

Will record it again next time im down at the car. Still really busy with work. Im going to try the new starter back in the car minus the the spacer. Looking at the starter shaft on the new one the round disk bearing on the end of the shaft is a couple of mm nearer the gear than the old one. The old one also has a couple of mm travel on the shaft inside the housing which the new one doesnt. Its a guess but if the old starter is worn and the new one doesnt need the spacer it could be the end bearing contacting the flywheel on the gearbox side. Unlikely as all that is dont know what else to try but it seems like something is in contact until it expands through engine warm up and finally has clearance

Why not remove the starter, tape up the leads to stop any shorting and bump start the car. If the noise has gone its definitely starter/ring gear clash.

While that sounds like a possibility I would rather not bump start a car from cold...

Ive seen too many knackered lay shafts in my time....

Bump start a car in top gear only and at trotting pace....I'm not sure Rob can achieve that from his garage. Oh for a starting handle....

Its most unlikely, but if you are looking at starter motor stuff is the starter ring gear coming loose from the flywheel ? And the expansion of the flywheel when hot tightens it ? I would have expected noisy starter problems though. If the flywheel was touching the starter motor drive gear I would expect to be able to feel that at the back end of the motor shaft. ( Remove the rubber sealing grommet to access it perhaps).
Tony.

Hi Tony thanks for your post. REALLY REALLY hope you havent got it right though as the thought of the ring gear coming off while runnimg fills me with dread almost as much as the thought of having to remove the gearbox again!

Always thought you had to heat the ring gear to make it go on a cold flywheel and assume if the ring gear was coming loose it would be either noisy all the time or only when hot???

It certainly starts the engine fine. How risky to the flywheel/transmission would it be to try to start the car in gear and see what happens??

Hi Tony

As Jonners says bit tricky to bump it where it is but its booked in for all its remaining bodywork and respray from 30th December so might get an opportunity to try that then

Thanks for your advice

Hi all

Have a few videos from different aspects with the noise and then it clears after fully warming up just to see if it provides a clue to the knowledgeable dolly community!

Becomes intermittent

Spigot bearing or clutch plate? It sounds quite loud!

Hi Bill

It was doing it before and after replacement of spigot and clutch is new

The sound is coming from the bellhousing which points to the clutch or flywheel so I would be pulling the gearbox off and starting my investigation there. I know what a pig of a job it is (I've had the gearbox off a few times on my Dolomite 1300 and it was bad enough on the non-OD box). It sounds like something's rubbing so there should be some tell tale evidence once you have it all apart. The alternative would be to see if everything beds in once you can start using the car on the road. It would be better to start your investigations while you have the tunnel off. I'm wondering if the clutch plate or release bearing have been fitted the wrong way round. I once fitted a release bearing the wrong way round on an Acclaim which made the clutch heavy. Have you tried to drive the car at all rather than just running the engine with the car stationary?

Edit: Just been going through this thread and I'm wondering if the flywheel is rubbing on the engine backplate bolts or if the engine backplate bolts haven't been fully tightened up. With the gearbox off, you should be able to check for clearance. With it all apart there will be some wear marks if this is indeed the cause of your problem.
