So I m now to the point of bringing out the all bearing Ralmark pulleys I purchased from the Luscome foundation as my new cables should be in this week and fuselage tubes in interior areas about to recieve the final coat of aerothane Sun Valley Ivory. Was surprised to see the new pulleys are not the same width (will require washers) more over the grooves are not as deep. Anyone else used these? The depth or lack there of is really bugging me. It is significant.

Do you mean the groove is not as worn as the old pulleysOriginally posted by Jim Herpst View Post
? Shimming with the washers is not an issue.

I would think doubtfully the groove ALL wore out exactly the same depth and very much deeper . Am I really missing this? If so wow . Those suckers are worn! You probably know better than I do is the truth. As far as adding washers to make up the width not concerned. More worried that the new ones were deep enough.....Last edited by Jim Herpst; 10-22-2022, 20:37.Comment

Ya know in looking closer at the old vs the new it does look like not asmuch difference as I thought. Perhaps 3/16 difference. Your thought is probably spot on.Originally posted by 3Dreaming View Post

I have had to custom build cables as they are installed, some prebuilt just don’t fit in every airplane.N29787

Yes the ones that I had McFarlane make up were from the old ones with that thought...Originally posted by astjp2 View Post

I replaced my originals with those ball bearing ones. Much better control feel. The old 1941 pulleys had grooves worn in them matching the lay of the cable strands, and the bushing to pulley contact was worn-loose. Washers were used as inter-pulley or pulley-bracket shims.
