Lucky Phil Posted July 31 Share Posted July 31 (edited) Not only the aluminium oil pump gears that fail on the high cam engines. Total rubbish. Edited July 31 by Lucky Phil 3 1 Link to comment Share on other sites More sharing options...

Don't know the image was sent to me from Joe Caruso because we discuss engineering things/designs etc. I have several sets in my workshop with bad drive face wear on the teeth which I don't really trust for the reason shown in the image. Every material has it's place and aluminium for cam gears isn't one of them for mine unless it's some sort of sprint engine and longevity isn't an issue.

pete roper Posted July 31 Share Posted July 31 I have a whole ‘Chamber of Horrors’ file of pics of Alloy timing gears and alloy/steel composite sets. None of them are, or were, ever worth a pinch of shit! Criticising them has led to threats of violence being made against me by mentally unstable and drug-fu*ked individuals so I tend not to say anything about them nowadays beyond just advising strongly against their use. I’ve spoken with Joe about these gear sets though and we’r in complete agreement. You wouldn’t use them in a lawnmower! Much less a motorbike! 3 Link to comment Share on other sites More sharing options...
gstallons Posted July 31 Share Posted July 31 I've seen gear drives , straight-cut gears ,etc. for car engines . They sound righteous . Gear driven camshafts are the norm on diesel engines , The stuff they are peddling for the M/G powerplant ? NO WAY . It is a waste of time to discourage someone from using it , they know it is what they want , let them run it and find out or "you must notta put it in there correctly" .

Weegie Posted July 31 Share Posted July 31 I replaced the OEM alloy gears in my HiCam engine with steel versions from Joe The OEM crank driving gear is steel, but the oil pump and cam were allo I just thought it was prudent, the amount of effort to turn an engine and compress the valve springs said to me that it might not be prudent to have alloy as a suitable material Link to comment Share on other sites More sharing options...
GuzziMoto Posted July 31 Share Posted July 31 Gear cam drive is good, but aluminum gears for that are not a good idea for a street motor, as said. It just isn't what aluminum is good for. Strange that Guzzi went with some of the gears in aluminum for the high cam motor. But they do screw up occasionally. That said, while I would convert a chain drive cam set up to gears, I would only do so if the gears in question were steel or another suitable material. 1 Link to comment Share on other sites More sharing options...
Admin Jaap Posted July 31 Share Posted July 31 I changed my Centauro engine to chain cam drive, because I didn't want to risk exploding gears. Link to comment Share on other sites More sharing options...
