b44 gearboxs

[petti7676]

hi all ive just built my 3rd new b44 and ive come across a minor issue that ive never had before the crown wheel to diff meshing seems very tight and notchy as ive built 2 of these cars before and in the same way could anybody shed some light on what if anything ive done wrong or have i just not notice'd this on the other 1s . Dont wont to strip my gearboxs as soon as i run the car lol:cry:

[Team No Idea]

Im just building i new kit today, again i have built a few of these cars now and in this particular kit the diffs do seem to have a very tight mesh.....i have removed 4 shims from one side where the instructions say fit 6 and although it feels looser it is still very notchy.....anyone had any ideas with this one???:confused:

this is because the production tolerance of these gearboxes is very bad. u shouldnt build a gear like shown in the manual (with the number of shims). Try to build it, that there is no axial run-out of the diff...
