wimpus Posted December 20, 2021 Report Share Posted December 20, 2021 Hi, Im in search of another flywheel for my Spitfire 1500. Now .. mine measures from teeth to teeth (diameter) 30,1cm. But it has 200.000miles Friend of mine had one, but ringgear had a number on it.. Dolomite 1500 flywheel and measured 30,5cm Ive had 2 guys that sell 1500 flywheels not sure if dolly or spitfire. But also measure 30,4 / 30,5cm. Also.. Dolomite 1500 was never sold here ! So whats really the difference between them ? Link to comment Share on other sites More sharing options...
Colin Lindsay Posted December 20, 2021 Report Share Posted December 20, 2021 Easiest thing is to just search for Triumph Spitfire flywheel and see what options come up. Rimmers show two; one with a 7/16 bolt to crank for the UK market and one with a 3/8 bolt fitting for the USA. They don't mention any difference in diameter, though. I know the ring gear differs between inertia starters and pre-engaged starters; I wonder if that includes the thickness? Link to comment Share on other sites More sharing options...
Anglefire Posted December 20, 2021 Report Share Posted December 20, 2021 Mine has a Dolly flywheel and pre-engaged starter - that was a nightware when it packed up! Anyway. I do also have a spitfire flywheel in the garage - but it would cost a fortune to send to Belguim. But can measure it up easily enough. Link to comment Share on other sites More sharing options...

Anglefire Posted December 20, 2021 Report Share Posted December 20, 2021 If I haven't done it by this time tomorrow, give me a poke - I will have forgotten! I know exactly where it is - just couldn't get to it today for several reasons! Link to comment Share on other sites More sharing options...
Nick Jones Posted December 20, 2021 Report Share Posted December 20, 2021 I think the flywheel is the same but the ring gear is different. The Spitty starter really doesn’t work with the Dolly ring gear. The Dolly starter is unique to the Dolly 1500 and thus nearly extinct. IIRC the easy “tell” is that the chamfer on the teeth faces backwards on the Spit and forward on the Dolly. Nick Yes, bigger bolts, but also the “pot clutch” with the ring that makes refacing bloody awkward. Genius design. Link to comment Share on other sites More sharing options...

It is and I had a right game getting a new one sorted - they had to fit a new gear to mine to get it to fit correctly - They being Powerlite in Brierly hill. Luckily not too far from me. Interestingly, they do show the RAC801 as being suitable for many Triumphs - but I suspect its not correct.....

wimpus Posted December 21, 2021 Author Report Share Posted December 21, 2021 Had anothet look and a few guys i know had a look. But bought a flywheel in the Netherlands, 35 euro and looked good (he seemed to have many). Will see ! But will not trow the old one away.. you never know 😂. 1 Link to comment Share on other sites More sharing options...
Ian Smith Posted December 22, 2021 Report Share Posted December 22, 2021 Just a really long shot.... Really looooong........ Allegro-Maxi 1500-1750? I don't know why, just something at the back of the head. Not a flywheel, but a ring-gear. Link to comment Share on other sites More sharing options...

wimpus Posted December 27, 2021 Author Report Share Posted December 27, 2021 It was indeed the pic. The teeth are good. But... can you spot the problemo ? My original vs the 'new' one.. Link to comment Share on other sites More sharing options...
wimpus Posted December 27, 2021 Author Report Share Posted December 27, 2021 Ok.. will tell you. One is euro spec, the 'new' USA. European used 7/16 bolts Usa 3/8. So drilled the holes bigger on the 'new' flywheel. Link to comment Share on other sites More sharing options...

I had to do that on mine, too, but in my case it was because I have a 1300 flywheel (and clutch and gearbox) on a 1500 engine. 1 Link to comment Share on other sites More sharing options...
