Skid!! I need your help!! I've got a lovely vintage Fox, problem is it has gearbox troubles!! When I bought it the diff was not quite working correctly, so I replaced all the gears with a very costly vintage gear set I found on the bay (but not the drive shafts coz I was lazy and the C/E clips are fiddly and the old hex drive shafts seemed ok). I'm running a 23 x 2 motor in it. All was well on my first test run for about three minutes at which point I lost all drive, and the new diff was no longer working whatsoever! Opened it up and found that one of the plastic bevel gears had split in two clean down the middle! Assuming that the old plastics were brittle and with the Novafox coming out I then replaced all of the gears with a new plastic gear set. First test drive went fine and I ran it for half a pack on short grass with no troubles at all. Thinking my gearbox problems were over I then took the car out yesterday with my nephew and the first few minutes on gravel it ran fine but once we went into the woods and drove on dirt/loose mud and the diff had to really do some work (i.e got stuck a few times with gear diff just spinning one wheel) my lovely vintage Fox started crunching and grinding and it seems we have the same problem again!! aaaarrrgghhh!!! I've another new gear set on order, and fully expect to find the same bevel gear snapped in two when I open up the gear box again......
Any clues at all??
Please!!!
p.s. I've got some unused NOS hex driveshafts I'll install this time round but any advice or Stig wisdom would be greatly appreciated as I want my lovely vintage Fox to be a happy healthy gentle runner not a broken shelf queen!!
Almost wish I'd just bought a Novafox - but as you know vintage is king!!! |
