Day 2 - Gearbox Out

After getting the bench out yesterday, the next big job was to take the box out.

First was to take the props off (you can just see the rear one is off). This revealed another possible head-ache. When the last bolt was taken out a large glug of transmission fluid followed, could be a knackered oil seal on the output shaft....



With the props off we could start unbolting the bell-housing and mounts. Everything unbolted easily and the box seperated from the engine without to much fuss, what did slow us down was one of the mounts not wanting to seperate, we ended up taking the whole mount off the chassis.

And out it comes....



With the box out of the way we could see that the diaphragm 'fingers' were badly worn, you can see the wear ring in the centre. This was caused but a worn thrust bearing (pictured below)




And all that is left is a large hole....


With the box safely on the ground we will be able to investigate the cause of the problems. We have already noticed that the input shaft has a little to much play in it so who knows what else we might find, lets hope nothing to scary!
