Ford 6700 Dual Power Transmission

[Marius47]

The dual power gearbox is limited to 25 km as I can increase it to 30 km ?

Wide 38” tyres would give a larger circumference, and a higher road speed.

[Marius47]

Yes, but the ones made for Europe are limited to 25 in the rear differential from what I heard.
That's why if he could change that limit to the original 30 km.

Hi,

Rev it up to 2400. And enjoy the time in the tractor seat instead of driving faster and having less time to enjoy.

There were these differential differences through the whole range from the 6X 1000 series onwards, tractors built at Basildon for the UK market had a diff that gave higher road speeds whereas any Basildon built tractors that went to Europe had the diffs that restricted speeds to 25 kph. You will be able to fit a UK diff in your tractor to increase road speeds.

A friend has done a great conversion of a Belgium built pre-force 5000 by fitting the UK diff and a 7840 engine modified with a Bosch inline pump and turbos, large diameter rear tyres - see it go on road runs!
