I have a j type on the stag and no brackets are in the way. U can get to
it. Oil will come out not sure how much. Change two o rings while u have it
out. Google the no. Of teeth for the 6. I have a j type for a dolomite
sprint and had to swap out the gear. .

 The no. Of teeth were different as well as the length

Just fty. At the end of the OD is a stamped. On the Stag and sprint are 6
start. This is the no. Of threads on the big gear in the OD.
