Fan Transmission Pressure Adjustment - Hardi COMMANDER TWIN FORCE Instruction Book

Fan transmission pressure adjustment

Fan transmission ports and connectors are:
A = Pressure port
B = Return port
D = Drain port
P1 = Connector for working pressure measurement
P2 = Connector for feed pressure
R = Adjustment screw for feed pressure
S = Suction port
The transmission feed and working pressure are checked as follows:
1. Connect a 40 bar pressure gauge to the feed pressure connector P2, and a 400 bar pressure gauge at the working
pressure connector P1.
2. Set the tractor P.T.O. at 540/1000 r.p.m. - check with tachometer.
3. Set the blower at max. speed.
4. Check the feed and working pressure:
Feed pressure P2: 15-20 bar
Boom width
Working pressure P1 (approximately)
5. Adjust feed pressure if necessary.
ATTENTION! Failure to reach feed and working pressure indicates that the transmission needs overhauling.
