When I bought my 1st P6B three weeks ago the speedo was not working,so I thought it must be the cable,took the cable out sure enough broken at the g/box end,fitted a new cable still no drive from the g/box,cable doe's not turn so I can only suspect that the drive in the g/box is at fault though the cable will not turn by hand when connected to the box.Now the thing is where can i get a new g/box speedo drive as this is a 5 speed SD1 LT77.I have not yet taken the drive out of the box to examine it as I only have ramps no pit and did not wish to lose all the oil and cannot see it being anything else? unless someone has had this problem before?I am assuming its the nylon cogwheel.
