    Howdy,
    ina a bit of trouble with my bogballe spreader. Anyone have any experience with a bogballe gearbox? The selector between forward and reverse spreading is letting the gearbox slip. I am wondering what is the correct position for the selector and its spring?
    Thanks

    If its the older type bogballe, the slip clutch on pto might be ceased which in turn will cause the main shaft going into grarbox to strain from the initial stresses of pto starting off. There is a collar on this shaft that slides back and forth on a keyway which is part of changeover mechanism, and because of strain in shaft is not sliding properly and is catching inbetween changeover. quick solution is to open top of gearbox and tap collar into place and not use changeover again until you change shaft. Either way cleaning slip clutch is a must as next thing to go will be roll pins in gearbox under discs.

    Its the newer type. The shaft in the gearbox broke and got that sorted I thought. Worked fine for a few hours and then stopped. It just would not stay in gear. The collar keeps sliding out, I think because I do not have the selector in position correctly allowing the collar to slip out of gear. I am curious as to what position the selector spring should be to keep pressure on the collar. I just cant get it to keep tight.

    I think the slip clutch must be shagged causing the shaft to go in the first place. Ill order a new one in the am anyway.

    What I have learned for anyone else in this situation,

    the gearbox covers must be spotless when being put back together and its a hard job to clean off all the glue.
    the gearbox takes 750 grammes of grease. use a soft grease. MP grease is too thick.
    the gearbox must be level so try avoid taking the box off altogether, just try open the top.
    use locktight on the rear allen screw and make sure its VERY tightly screwed.
    The gear selector spring must be sprung back onto itself and then replaced onto its lever with the small metal piece sliding into the overlapped spring. this is hard to do and be careful when replacing the cover that it does not fall back off again.
    check the pto shaft and make sure its very free because it can cause small vibrations which can do damage.
    keep the slipclutch loose. it should turn a couple of times before engaging.
    Try not to break it in the first place as its a nightmare to fix.
