Multione GT45 Swivel Joint Modification

[Dean Lofthouse]

GT45/50 centre swivel modification. Been meaning to do this for some time and finally got round to doing it.

 

This joint allows the two halves of the machine to rotate a certain amount to follow the ground and keep all four wheels in contact.

 

A common fault was there were only three bolts holding the swivel stop plate, which would shear allowing the plate to come loose and the machine could very easily tip over.

 

My mod was to machine another three bolt holes to share the load and so strengthen it. It has solved the problem.

 

My other main aim was to check the pivot bushings and pins, couldnt believe the hardened steel bushing weren't worn at all, just the pins showing slight wear. The machine is 16 years old with 942hrs and has worked hard.
