PhilNW 40 Posted September 25, 2022 Had a previous problem with a Tranx diff which thought I had cured see below, I have not used it much since then. The bad news if that the gearbox whine is still there in 4th and 5th gears, (1st 2nd and 3rd are OK) and a lot of backlash/play Replaced diff bearings and input shaft bearings when it was rebuilt, no obvious problems with 2nd shaft bearings and no metal swarf on magnet when I stripped it. Gearbox was fine for years before the casing got damaged , so is it another problem? I have missed something or put it back together wrong? Any thoughts what I should look at ?

dcc 855 Posted September 25, 2022 Personal experience, whine is a poor mesh between the faces of the gears Share this post Link to post Share on other sites
SRDT 146 Posted September 25, 2022 3rd and 4th are joined on the secondary shaft so if it's a poor mesh it should be from the primary shaft side. When replacing the bearings did you set the preload correctly? Share this post Link to post Share on other sites

When replacing the bearings did you set the preload correctly? I think so, i was checking the preloads when I found out about the damaged diff cover. Cant work out why only 4th and 5th when 3rd is connected to four. As a first step think I will take off the outer cover to check for any mis-meshing on 5th Share this post Link to post Share on other sites
