Adjustments - H&S 4142 Operator's Manual

HORIZONTAL BEATER DRIVE CHAINS
Both beater drive chains can be adjusted by loosening bolts
(A) and sliding the poly tensioners toward the chain until
1/2" of deflection can be obtained on the opposite side (B).
Retighten the bolts (A) when deflection is obtained.
VERTICAL BEATER DRIVE CHAINS
Vertical beater drive chains have a spring loaded tightener
system. If chains become loose, replace the worn chains
or check if the springs are stretched out or worn, replace.

TIMING OF BEATERS
The beaters must be timed so the flighting of the
opposite beater is about half-way between the beater
being timed. To time the beaters, remove the top
shield and remove the chain coupling so the beater
can be turned to the proper position. Re-connect
the chain and re-install the shield.
WHEEL HUBS
To adjust the wheel hubs, tighten the castellated nut on the spindle to the point where there is no
end-play and a slight drag on the bearings. Replace the cotter key with a new one of the correct size.
