Hi
I own a Zennoh ZB6000 which is supposed to be identical to the locally delivered Kubota B6000.... well this proves otherwise
I broke a gear a few months ago when I accidentally dropped the clutch with the PTO engaged. orangetractortalks.com/I broke a gear
It smashed 1st speed /PTO low driving gear into 4 pieces so with the help of the parts manual I ordered a replacement only to find it has one less tooth (13 instead of 14) and is 2mm longer... WTF!!!
Back to the dealership we double check the part numbers and its the right part. So whats going on.
I go home and count the number of teeth on the gears in my gearbox and compare them to the parts manual... The other gears are different too. Back at the dealership we come to the realisation that Jap market tractors have different gear ratios to suit the tilling machines they are permanently attached to.
Luckily the 2 gear that this gear meshes with have 29 teeth in both my tractor and the parts manual so theoretically it should work.
So the solution... put the gear on the lathe and take 4mm off it and make a new spacer 2mm longer. The reason for the -4mm +2mm was to make the teeth line up with the meshing gear and allow enough room for neutral
The result
I still havent finished putting it back together but I'll let you know how it goes.
As it sits as of this afternoon
