I am putting a Nova gearbox in my STD A10, it does not come with the speedometer drive gear. I went down to see Len Haggis to buy a new STD gear and driven gear after trying email, but, I think from his reaction he only orders for the RRT2 boxes. I cannot find other suppliers. I have tried to remove my current gear by drifting with a metal rod, with heat to no avail, the retaining pin has all been drilled and drifted out. The really annoying thing was that I drifted it in.
Has anyone advice on how I can get the speedometer drive gear out from the layshaft and for that matter how to get it in straight when refitting?
Not much help but they usually pull out without much force.
When putting the gear in they often need to be redrilled as the holes dont always line up. I think the shank is soft compared to the worm.
Thank you Julian
In desperation I bought gears from India, only £30 ish delivered. The gears measure up well but as you said the hole in the drive gear is about 40 thou too far back leaving the gear proud. I cannot redrill this as is (the gear will move) but will need to turn 90 degree and drill a new hole, it is possible.
However, the driven gear shaft has not been squared off to take the cable. Is this a heat and hammer or a specialist job. I need to decide whether to return or accept a discount.
It will be difficult to square properly.
If it was mine I would get my money back.
