Broken/stripped cam gear

Hiya All,

So, I'm looking at the Brad Penn website and I run across this line in the SAE 30 wt page...........

"Excellent oil for vintage and air-cooled applications requiring a straight grade oil."

Question here being............Do any of the PDX contingent know if this stuff is avalable in the Portland area?

So is your builder suggesting the lack of zinc caused wear only in one area on the cam gear? And left the other areas alone? That's....interesting.

I agree with Colin: the cam gear mesh wasn't good from the beginning.

That's what he said. And being the person who he is I was very surprise he would say some B.S. like that. And he knows that I am a field technician for Caterpillar.

That's freaky. I've never heard of that before. What would cause a shear of 1/3 of your cogs?

It is available but I can't remember who I found carries it right now. It was a shop down off of Columbia I think. I think there is a spot somewhere on their site to look up local suppliers.

Hiya Jasan,

I tried their website. No retail locater there.

Looks like I just may have to zap an e-mail their way for specifics.

That cam gear looks exactly like the one I had mentioned in an earlier post.

I'd like to understand the failure mode....

I know this is old but I thought I would mention that I too had an AVP cam strip out on me.

Was it a bolt-on? Was it magnesium? Did it have my favorite cause of failure, non-concentricity where a tight spot causes destruction of oil film/galling?

What ever happened here? Was the engine rebuilt? Did the guy stand behind his work? From your location, i suspect I know who the rebuilder is, and he is doing a 2L engine for me, as we speak, with a Schneider cam. Do I begin to pace now?

I don't think it would be taboo to just say the guys name. were talking about headflowmasters right?

Yes. I'm not really concerned, though. Things are always happening, and risk is inherent in about everything you do. I guess I'll just get very good messing with these engines, over the long haul.

Are you asking about the resolution of RZAR's engine from 2009? Shoot him an email and ask him where he has been, that we all have been waiting and WAITING . . .

Shame that he left, but in a 2009 thread, he did say:

I had my engine rebuilt by Adrian at Headflowmaters

This is the first time I've heard something negative about him. Just last week he spotted a weld on my core cylinder head that two other shops missed.

Whoa! Guess I missed that one. Nothing that paying attention in middle school English class couldn't have resolved. Or picking up some books over the course of years and reading them, and looking up the words you don't quite get. But wait! We are in the Land of Today, in which dummies run amock, Judge Judy rules by sarcasm, and daytime TV spreads brain death quicker than runny noses in daycare. I'm lamenting that I have so few opportunities to use the word, "niggardly" in the course of daily affairs. Those who have used it in public speech in recent years have paid a price for being, well...educated. I take serious offense with those who mess with my language, as in the following:
