Need a little help in defining the gearbox on my Thwaites Nimbus Dumper as the output shaft oil seal is totally shot (see photos). Looks like it has also had some rework as the upper casing has been welded in the past. Also need a service / parts manual for this gearbox as the gearstick cover is missing so would like to get a new part (if possible) plus it’s jumping out of gear or sticks in gear. So I think I need to strip it down to check the selector shaft / springs
Any help or advice would be appreciated, once the gearbox is done need to fix the Salisbury axle hub oil seals
