7441 upgrade

[johfit]

is it true that the 7441 model can have the pump turned up to give it the same horsepower as the 8441 and is there any problem with this .......how is it done

if you have TIER II engine, 8441 has got small intercooler, 7441 don't.

But you can still easily twick 7441 to give 100 hp from PTO. Just increase fuel injection and modify that pressure indicator which is mounted in pump. Open cup with 22mm wrench and loose that spring with 10mm wrench.
