I used the auto supply stuff - “weapons-grade” is not so available up here in Canada! 😉. I brushed a thin film of the compound (basically grit in grease) onto the mating surfaces, mated them, and rotated the cone back and forth. Did not do complete rotations only because Mr. Robinson told me not to in shop class back in ’78. (lawn mower valves – different thing as they don’t rotate in use.) Again, make sure you reassemble the parts as they were removed, (mark with a punch) and be really careful to clean away the compound. A solvent wash will show you how much grit there is, and how gritty is that grit.
Here is a pretty decent link on this, one of the posts refers to a site with photos, where you can see the various parts. You will need a gear puller. http://forums.sailinganarchy.com/index.php?showtopic=154931 Dave Message: 1 Date: Tue, 10 May 2016 09:07:32 -0400 From: "Rick Brass" <rickbr...@earthlink.net> To: <cnc-list@cnc-list.com> Subject: Re: Stus-List Soft thumping/banging when in gear at low-rpm?
