Re: [Amc-list] Trunnions for Tom Jennings

[tom jennings <tomj@xxxxxxx>]

YEah, those are trashed. Years of grinding parts without lube did that. And
all they need is lube every 30,000!

Were the caps tight in the arms? If so, you're up one, it's tough to find
arms.

I would NOT re-use the caps, I'd replace caps and trunnions. The worn caps
will eat good trunnions. Used is fine; mine have 300,000 miles and I lube
'em every year, last time I had them apart they were like new.

Grease seals: Most of the AMC parts guys have 'em, but these days, I'm using
generic O-rings. There's nothing fancy about the seals; they just keep crap
out. They should be close fitting but not tight. When you grease things
normally, then wipe it off with your finger, that's all that's needed to
keep crap out.

NOS trunnions (!$$$!) will come with "new" caps,  but all that old rubber is
old and stiff... hence my using O-rings. they're cheap enough to buy a size
above and below and just leave the extras in the junkbox!
