FridgeFreezer Posted July 29, 2009 Share Posted July 29, 2009 Not that I'm aware of, I believe the thread on the output shaft is to do with the build process of the gearbox. Quote Link to comment Share on other sites More sharing options...
reb78 Posted July 29, 2009 Share Posted July 29, 2009 Nope. No Nut. The input gear is held in place as its bearings sit in races at wither end and the race at the rear of the input gear is in the bearing carrier which is initially held in place with to recessed torx screws. This it then secured properly when the PTO cover plate is bolted in place. The preload that holds the input gear and bearings is set by the thickness of shims in the bearing carrier - this determines the 'tightness' of the bearings in their races once everything is torqued up.

ped Posted July 30, 2009 Author Share Posted July 30, 2009 cheers lads when transfer box was replaced last year with a range rover auto one ,discovered that some kind soul had welded a nut on the end of the main shaft(4 hours of extra pleasure laid on my back in the rain) as the range rover didn't have a nut on(auto box)and no thread i put it back on the same as it came off and thought it must be lt77 boxes that had a nut now due to alot off towing i need to go back to a 1.4 t/box and just wanted to make 100% sure that there is no nut many thanks ped Quote Link to comment Share on other sites More sharing options...
