Harrier 56 PRO

[JimE]

Does anyone know if it is possible to convert Harrier 56 varidrive machines into harrier 56pro with the fixed speed system?

I have several customers with varidrives which just don't stand up to commercial use.

The Hayter 56 v/s is indeed pretty feeble in the transmission department. It is not at all unusual to have to replace the gearboxes, but to be fair the first thing to check are the drive belts. They do wear very quickly and the slip is often due to the belts rather than the box. Belts are cheap and easy to replace.

 

As to coverting to the Pro transmission, I have not tried but it looks feasable. You would need at the very least,

new gearbox

new belts

new centre double pulley

all the pivots and equaliser for the centre pulley, as well as the tension spring.

 

This would not be a cheap exercise and would require more research first to ensure that the roller bracket and the under chassis are the same.

 

Better IMO to sell the 56 v/s on the bay and buy a new 56Pro or similar.
