[Healeys] Another O/D issue

[m.g.sharp at sympatico.ca]

Thanks Mike,  I might take the switch off the other g’box first and try it.  However, given that the switch has a steel ball on the end which engages onto the brass shift fork, I suspect it is the brass that wears.  So unless the replacement switches are a smidgen longer, I don’t see how that would change things.  Anyhow, I know what the problem is, so when I have it apart I will figure out a solution.

 

Thanks,  Mirek

Hi Mirek, normally there are thin fiber washers under the switch which are used for adjustment. 

Most are fitted with 1 washer but occasionally you will find 2.

Removing a washer will effectively move the switch further into the gearbox which should resolve your issue.

If there are no washers it's probably best to buy a replacement switch. The switches available from the usual suspects seem to be quite reliable.

Hi listers, I am finding that my BT7 (i.e. sideshifter) is dropping out of overdrive if I wiggle the shift lever to the left.  This is without doubt opening the contact in the gearbox switch that only permits the O/D to operate in 3rd and 4th thus causing the O/D to disengage.  Pushing the lever to the right re-engages it. I do not recall any adjustment on the switch to screw it in further, in fact I think it is a pipe thread and will only go in so far.  I am not sure what part of the shift lever actually bears on the end of the switch to engage it.  The workshop manual is not much help in figuring it out.  Is it the switch or is it what ever it bears on when in 3rd or 4th?   I have not had the g’box cover off to look at it yet but thought I’d ask the list if anyone had encountered this.  

 

Thoughts and ideas?
