Hi
I have just ordered some of Steve Maneys rubber crankshaft oil seals for the race bike. This runs a belt drive & guard only, I know Steves seals work but it got me to wondering.
I have a list on my old file with peoples suggestions for a variety of alternatives. ie gearchange & kickstart "square o rings"
Any chance of us updating this list? please?.
Thanks Chris

You can buy the rubber seals at any bearing shop. I forget the dimensions but take your old seal with you and you will find that they are a fraction of the price Maney charges.
(and they won't have his name in big letters stamped on them like most of his stuff does)

Oil seals

Hi John
Nice to hear from you.
Steve was down your way Phillip Island I believe. He didnt say how well he got on but I saw him at Snet in August getting a ride in. He said its nearly 3 years since he last raced.
I purchased a couple of crankshaft seals as I heard that his are really good with an open primary case. I have the codes written down now.
I really needed a set of his curved 34mm inlet manifolds for Amal Mk2 carbs & they are sweet but as you say expensive. Then again if I could make anything this good I would want my name on it!!!
I also got a cover & bearing for his clutch outrigger bearing system that I picked up a while ago.
I am slowley building up a 750 but accomplished nothing over the winter. I have the big bore maney alloy barrel MK3 engine but I think I would have to alter the engine plates & possible the exhaust which touches 750 primary cases. The extra length of the crank & the cases on a MK3 electric start engine might make it a no no.
I am going to Donnington for the Norton day which is on the friday of the classic race weekend, so might pop it in my 750 flat tracker & get a run out on the track friday. As its all set up with alternator etc I might as well use it.
Let me know if you are out this season.
all the best Chris

Inlet manifolds are easy to make. I did my own ( sort of). I had a machinist make two cylindrical stubs that the carb rubbers went on and welded them to a pair of standard inlet stubs after I'd cut the ears off. Finally smoothed out the insides. Easy, cheap.

I ran 36mm Mk2s on it. Good for top end, but a bit flat below 4000rpm.

Maney was at Phillip Island. I'm not surprised he didn't say how he did. My mate beat him riding a 500 Triumph against Maney's 1000cc Norton ( did they make 1000cc Nortons in the early 60s, which was the class he entered?)
