Fiat Lifters?

[geodoc]

Seems that I heard one time from someplace I can't remember, that Guzzi lifters of the kind found on round-barrels were common to some sort of Fiat. Seems sensible enough - not having to source a special part & reduce production costs, etc.

Anybody know if this is actually the case and if so, what model they're from exactly? Now with (1) new lifter being $75 a $15 one for a Fiat would be rather welcome.

Hi George,
Given that the original big block was designed to fit into the Cinquecento - my understanding is that it was designed as a hi po option - that would be my guess. I'd like to know if the bell housing/clutch is the same as well

I did find a picture of the cinquecento lifters and they at least look the same:

they seem similar.

The good news is they are cheap as chips as you suggest.

You can of course have them reground - most cam grinders will do it. In toronto Canada Chrome and Crankshaft used to do it. From what I know the chill is deep enough to take at least one regrind. I have found an awful lot of used lifters - at least in my fairly small sample size - 5/6 motors - that have pits.

No doubt Pete could give us a better idea of how often this happens.

In the cases I looked at the pits did not cause any cam failures but who knows what the long term would be - I just replace them. Whether these are inclusions or flaws in the chilling process I don't know. I suspect inclusions as the chill should be consistent.

Heh Chris,

Excellent! I'll be calling up the local Fiat guy or maybe one in Seattle to ask about getting a sample to check out. If they're a cheap as the ones on the web page, it would be a reasonable replacement ~equal in cost to a re-grind. Assuming the Fiat ones are not made in place with a reputation inconsistent quality (ah-hum .....).

Colt Cams does the grinding work here:

They are the ones that do the B10 regrinds from the stock cores for MG Cycle. He does lifter regrinds for $10 ea. w/ harness test before & after.

Ordered one here to inspect and after I do, I'll let the forum know if the spec is the same:

Eager to hear the news!

Got a lifter from a Fiat 126 and discovered that though the outer dimensions are exactly the same as the Guzzi lifter, the radius for the pushrod ball-end is much larger even than the one for the later style push rod. You could get custom push rods from Smith Bros. with the appropriate ends, but then that kind of defeats the cost-saving purpose.

Oh well ..........................

Thanks so much for the effort anyway!
