MAINTENANCE

Tapflo LPX series

7.3.1.

Inspection of shaft

Visually inspect the shaft for twists or bends; replace it as necessary.

7.3.2.

Inspection of hub end

Visually inspect the rotor hub end for excessive wear; replace it as necessary. Each time the

rotors are removed, replace the O-rings on the hub.

7.3.3.

Inspection of shaft shoulder

Visually inspect the shaft shoulder for excessive wear and replace it as necessary. If the shaft

shoulder has a sharp edge, remove the edge with a file to prevent cutting the shaft O-ring on

installation.

7.3.4.

Inspection of gears and bearings

NOTE!

The rotor hub and shaft shoulder wear are caused by operating with a loose rotor

lug screw(s) for extended periods.

Fig. 28:

Backslash check

Gear backlash

With the fluid head and seals removed, feel for gear backlash by rotating either shaft by hand.

The other shaft must engage immediately. Perform this check three times at 60-degree

intervals.

If play (backlash) is evident, remove the gear case cover, check the gear teeth for wear and

ensure that the gear is not loose on the shaft. If the gear teeth are worn, replace the gears.

If the gear is loose on the shaft, inspect the shaft key and keyway; replace as necessary.
