Hi if you have a spare one, I need one please ,I have a 93sl by all accounts they changed around 1994. Thanks for looking.
Thanks for the reply, the helpful chap at protwins said anything post chassis number 12263 is the new type, as you say around 40 quid. Maybe if I get stuck I'll get a new style one and see if I can adapt it, it maybe worth a go,
Well that all sounds quite easy Steve!! I'm sure I can sort something for the summer, if needs be a sat nav will keep it on the road, my last couple of rides without a speedo were amusing sort of.! The 900 is certainly quite different from the 750, I'm not really looking to change it much but the exhaust headers look a bit restrictive especially where they cross over, open pipes I suspect are hard to come by too! Simon.
Steve should have just fitted the later wheel and axle and speedo drive.......... ......much less 'kin around even it didn't save much weight..... Nothing from the later speedo drive will fit the earlier wheel, not even the grease seal........ ........so it isn't just a case of changing the bearings, spacer tube, top hat bush and axle.......
It won't fit..........it will be too large diameter to fit in the wheel hub housing........ The early wheel housing is approx 52mm diameter and the later one is approx 58mm diameter........and they are machined differently in the housings........IE, the 'stepping down' in diameter is in different places. The later drive is approximately 52mm diameter and the earlier one is approx 45mm diameter (haven't had a chance to measure it lately). The driving rings are also not compatible being completely different in diameter and shape......the driving tags don't fit in the wheels the same way. Neither are the grease seals compatible, the later one being larger diameter, but thinner than the earlier one, so trying to swap the drives means they won't fit in them either. Here's chewy's photo of the different drives before I acquired both types..........You can clearly see why they will not swap over. Even the pinion gear appears to be a different length.
