Hi. Would anyone have an Agostini alloy oil pump timing gear they would like to sell ?Regards
An explanation: I recently bought a Centauro bottom end and it came with stock timing gears (steel crank gear and alloy cam and oil pump gears. After seeing that the stock oil pump gears can perhaps fail I figured the Agostini item might be a better option. They will go in a race engine so I'm not concerned about dwarf or longevity 'issues'.
Remember there is bushed oil pump not needle bearings, worth fitting proper one IMHO, OE gear def suss too, they all crack in same place, so Ago one should solve it, permanently.Concern about dwarves in another thread I think, some kind of fetish, vaguely related to timing gear failure maybe.Longevity more important in racebike, failure ruins your weekend but I think your answer is safe, I'd do it but prefer all Ago, as proven by every Guzzi racer since 1975 ish, inc Wittner, of course.
Dunno about the Ago gears but the early Hi-Cam tooth form is some really weird cut that nobody else has used since prior to WWII. I assume you know the tooth form is identical?Pete
Hi Pete. The gear I'm looking for is straight cut.
Yes I realise that, it's not the angle of the gear it's the tooth form.Pete
Well my cunning plan has hit a snag :-\. Removed the oil pump gear today and there is a taper on the oil pump shaft so apart from any pitch issues a straight shaft oil pump Ago gear wouldn't work.Time for Plan B.

That's one of Joe Caruso's effortsWon't be cheap and it'll probably be steel as I know Joe had a mod to replace 2 of the alloy gears with steel on the 4V motors and a Dass oil pump.PM me and I'll give you his email of you want, I just don't like posting it up on an open forum. He's very knowledgeable and very honest he will not sell you something you don't need or won't fitHe lives in EnglandJohn
Sean Fader can bush the oil pump for you.
I'll give him a call. Thank you.
