Blades?

less than 2"" (50mm) from the blade bar to the trailing

 

edge, combo blades should measure no less that 3.5""

 

 

 

 

(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

 

Spider?

as measured at the spider. A fi eld adjustment tool is

 

available for height adjustment of the trowel arms (see

 

 

 

 

Optional Equipment)..

 

 

 

 

Bent trowel arms?

Check the spider assembly for bent trowel arms. If one

 

of the arms is even slightly bent, replace it immediately.

If trowel “bounces, rolls concrete, or makes uneven

 

be done by moving the trowel arms up and down. If

swirls in concrete”..

Trowel arm bushings?

there is more than 1/8"" (3.2 mm) of travel at the tip of

should be replaced at the same time.

 

 

 

 

 

Check the fl atness of the thrust collar by rotating it on

 

Thrust collar?

the spider. If it varies by more than 0.02"" (0.5 mm)

 

 

replace the thrust collar.

 

 

 

 

 

Check the thrust collar by rocking it on the spider. If it

 

Thrust collar bushing?

can tilt more than 1/16"" (1.6 mm) [as measured at the

 

thrust collar O.D.], replace the bushing in the thrust

 

 

 

 

collar.

 

 

 

 

Thrust bearing worn?

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

 

Replace if necessary.

 

 

 

 

 

 

Blade pitch?

Check blades for consistent pitch. Adjust per

 

Maintenance Section instructions if necessary.

 

 

 

Spider Finger Screws?

Adjust per procedure in Maintenance Section.

 

 

 

 

Yoke?

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

Machine has a perceptible rolling motion while

evenly on the wear cap. Replace yoke as necessary.
