Hi, I am new to this forum, thanks in advance for any help that can be offered.
I am helping my neighbor out with a gearbox problem on his 7341. After he lost all drive through the gearbox a few days ago, we pulled the top of the gearbox off and found that the 3 bolts holding the bearing housing for the input shaft were broken. Subsequently we have now split the tractor and found that it is the main input shaft (not pto input shaft ) that has broken.
So the questions I have are:
1- Dose the gearbox have to be removed from the differential/final drive housing to be stripped for repair or can it be stripped in-situ?
2- if it has to be removed is the gearbox output just splined onto the diff pinion? the owner seems to think that the pinion has to be removed first before the gearbox can come forward and away from the diff/final drive housing.
3- if the gearbox has to be removed, can it be removed with out taking the whole cab off? The front mounts of the cab are bolted to the gearbox case.
4- what is the normal procedure for removing the gearbox? I was thinking if we could rotate the back half the tractor on its wheels 90 degrees so the gearbox is sitting vertical and the cab laying back horizontal it may be easier to remove the gearbox due to the vertical lift for its removal.
We don't have a workshop manual for this tractor and I haven't been able to find a downloadable one online.
Again any help will be much appreciated.
Regards
Ben
