Starter motors: changing from pre-engaged to inertia type?

[triumphdolomiteuk]

I've just compared the new starter against the original, the teeth look about the same on both. It has a spacer fitted already. I'm baffled now.

To be making so much noise, can you see where it has been catching/grinding?

Yes, just on the very end of the teeth, on the corners. It made a right racket whilst it was spinning, then the screech after it fired. Switched off straight away to avoid any more damage.

Automatic or manual? Have heard such noises before after people fitting high torques on automatics. The flexplate is not as rigid as a flywheel and can cause more noise.

I wonder with it being the ends of the teeth wether to try it without the spacer? It sounds as though the teeth are only just touching the ring gear?

Tony.

[triumphdolomiteuk]

It's a manual gearbox. I reckon what's happening is that after the engine has fired, the starter teeth are still in contact with the ring gear. I'm not sure how it could fit without the spacer, it locates the unit in position. I'm going to give the manufacturer a call in the morning and see if they can offer some more advice, they were very helpful last time.

Sounds like you need a thicker spacer...

[TrustNo1]

IIRC I had to fit about six of the spacer shims before it stopped grinding.

[TrustNo1]

The listing says it has 9 teeth which is correct, maybe as trustno1 says it might need a spacer? The GT6 has one standard, not sure about the 1500?

Similar to these.

I was talking about the thinner shims part number UKC1770.

[dollyman]

I forgot about those type

I would add some washers to space it off. one at a time per bolt hole. If the noise goes away you'll know the space you need.

Eurolec were very helpful indeed, the starter is definately a pre-engaged type, so that clears up that confusion. I'm going to measure the distance from the flywheel to the bellhousing and report back to them Also I'll give them the part number for the original one which came off so that they can identify it. If the new unit has a design flaw, they will modify it, but options on putting shims/washers in remain on the table. Thanks all

Eurolec, in Brierley Hill, ie just up the road from here?

Any benefit in me taking a 1500 standard unit into them for comparison purposes?

[triumphdolomiteuk]

Yes indeed, that would save me some crawling about with a tape measure....

[xvivalve]

It has always been said that the 1500 Dolomite starter is unique to the model, but I've never understood how/why it differs from the 1500 Spitfire and Midget starters; I suspect this exercise will identify why...

I'll try to get up there tomorrow or Wednesday...
