Fugly Posted December 15, 2009 Share Posted December 15, 2009 The gear selector pedal is jammed in the up position. I dropped the linkage off the gearbox end and the jam is inside the gearbox. I am assuming that i have confused the mechanism and the main spring is applying pressure to the gear selector mechanism. I was going to remove the large plate off the offside of the gearbox, as from the drawings i assumed that might release the spring pressure and allow me to relocate things. However ... I thought i had better ask advice first just incase :-d Quote Link to comment Share on other sites More sharing options...

I thought i had better ask advice first just incase :-d The bus bar has gone "over centre", the pedal needs a hard kick to release it. Select a gear, before you do it. Could be that the bands are out of adjustment. Do not try opening the box up, the pedal has to be released to free the box. Quote Link to comment Share on other sites More sharing options...
Fugly Posted December 15, 2009 Author Share Posted December 15, 2009 OOps.... :??? Patience was never my strong point. Thanks for the reply I removed the plate slowly and carefully releasing the spring pressure - I was expecting a huge bang when the bolt threads ran out but I could feel the tension coming off. I removed the plate and carefully lifted the spring out, followed by the bucket. The busbar shaft was now free, and moving nicely (Hopefully :sweat:) I just need to replace the spring - retension etc. It will probably never work again. What I did achieve though was seeing the sludge that was in the box after draining the old oil out. I measured the oil level before I started and it looked OK (slightly low though). The amount drained out was 7 pints (book says it should be 1.25 imp gall.) I reckon there is at least 1 pint of sludge and rubbish in there that would not drain out. So i need to flush it out somehow. The ferret has stood for many years and there was a lot of moisture in there too. Will post the outcome good or bad. Need some gearbox oil now - what shoudl I use?

Right, first the oil is a SAE30 engine oil. Good job you were aware of procedure for removing the bus bar spring, because it should never be removed under compression, could be lethal if the bolts had run out of thread. You might have got a "false neutral" and now when you put it back, with something like 3rd gear selected it may be alright. You say there is a lot of sludge and moisture, it makes me wonder if the band linings are breaking up or worn. Have you removed the tin cover on the top of the box? If so you will see the five band adjusters at the top, see how far down from the top face of the nut, that the male thread is. Better still, post some photos of these adjusters and bands.

Grasshopper Posted December 15, 2009 Share Posted December 15, 2009 The 2 at the bottom of the picture look a bit worn out as the threads protrude from the top of the nut. I guess the bottom one is 1st gear and the next one up is 2nd. Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted December 15, 2009 Share Posted December 15, 2009 You box needs an overhaul, 1st gear band worn out, 2nd well on its way, and 5th gear is well up on adjustment. I did see a new gearbox for sale on a website a few days ago, could be cheaper than rebuilding as it is a job that needs doing right, ie setting it up.
