combo blades should measure no less that 3.5 inches

 

 

 

 

 

 

(89mm). Trailing edge of blade should be straight and

 

 

 

parallel to the blade bar.

 

 

 

 

 

 

 

Check that all blades are set at the same pitch angle

 

 

Pitch Adjustment?

as measured at the spider. A fi eld adjustment tool

 

 

is available for height adjustment of the trowel arms

 

 

 

 

 

 

(contact Parts Department).

Thrust bearing worn?

Check the thrust bearing to see that it is spinning freely.

 

 

Replace if necessary.

 

 

 

 

 

 

 

 

 

 

The main output shaft of the gearbox assembly should

 

 

Main shaft?

be checked for straightness. The main shaft must run

 

 

straight and cannot be more than 0.003 inch (0.08 mm)

 

 

 

Machine has a perceptible rolling motion while

 

 

out of round at the spider attachment point.

 

 

 

 

 

Check to make sure that both fi ngers of the yoke press

running.

 

Yoke?

 

evenly on the wear cap. Replace yoke as necessary.
