VICKERS MK6B's resto

[colin jones]

The gear that fits into the housing here must be some kind of support idler, as it has a small gear that runs of the main bottom shaft but does not move and only ever runs on half the idler gear. I assume it served some purpose.

The housing is complete and the gear fits really nice and spins well. I just need to get it to fit into the jigsaw and remain aligned. Matt,, sorry I never answered your question of why I'm using steel. There is a few reasons. First is I have lots of different sized on hand, I find it easier to work with than alloy. It doesn't damage in the lathe chuck and you can give it a hammer with out distorting it. Welding is so mush easier as is shaping and I'm much better at welding steel than aluminium.

Colin, it looks to me that the little gear is the oil pump???
Great work sir!

[David Herbert]

I agree with Lynn, almost certainly to throw oil up onto the rest of the gears when first starting and if the tank is at an extreme angle. This gearbox is going to be a thing of beauty when finnished, I hope the front of the tank can be opened up easily so you can show it off. Oh - sorry - it's Bitish so almost certainly no access at all !

Are you going to have to make another one of these for the other Vickers ?

I continue to be very impressed, great work, David

[David Herbert]

Just been looking at the earlier photos of the gearbox again. Is this gear not the reverse idler gear? Half meshing with a gear on the output shaft and half with a gear on the layshaft? If not, where is the reverse idler gear as I can only see one provision for a third shaft ?

Lynn, I think you hit the nail on the head. There is no other gear that slides onto it, so Dave, it can't be the reverse idler. It is not at the lowest point of the transmission so I would agree Lynn, that it is just there to throw oil around. Dave, yes you are right that there is little to no access and the other Vickers will be all Hydraulic drive. Because I have no drive train at all, I just thought It would make sense to have hydraulic drive like a skid steer and I have a little bit of an idea about that. (Not a lot, but enough) I am very happy the way it is coming along.

This thread is a real inferiority maker for me.

Excelent job, thank you for sharing!

Hi Colin,
The gear in the bottom is the reverse gear, the sliding gear above it on the mainshaft is 1st and Reverse so slides along to engage the reverse gear. See the picture attached.

cheers Richard
