Track with Manual Tensioner
The manual tensioning block is an optional component for tensioning the track belt manually using a
tensioning screw instead of springs. This is sometimes required to prevent belt skipping when the track is
operated at full power in the reverse direction. Typically, the manual tensioning block is ordered with the
track from the factory but may also be ordered separately.
To remove the belt, do the following as shown below:
1. Remove the plastic cover plates and completely loosen the M6 x 40 mm SHCS to release the belt
tension.
2. The idler wheel will slide inward enabling the track belt to slip off the rear drive wheel.
3. Belts are installed again by placing the belt over the loose idler wheel, then slipping it onto the
rear drive wheel. Adjustment of the track belt tension and idler wheel alignment is described in
the next section.
Block Tension and Alignment
Before tensioning the track belt, ensure the track is clean underneath the belt.
1. Belt tension and idler wheel alignment are adjusted using the M6 x 40 mm SHCS located in the
end of the side plates near the idler wheel. Rotate the screws clockwise to tension and
counterclockwise to slacken. Apply Loctite 243 to the tensioning screws to prevent loosening and
stainless-stainless thread galling in the idler shaft.
2. Belt tension should be adjusted evenly with each adjustment screw until there is no obvious slack
in the belt between the idler wheel and the drive wheel. When this is achieved, check the belt
tension (see next section).
