Maintenance Instructions T27i
Adjustments
Blade Clutch (PTO)
Clutch Engagement/Belt Tension
The clutch engagement and PTO belt tension are
adjusted using the clutch actuator rod. Initially,
after installing a new PTO belt, after 10 hours and
every 100 hours thereafter, check and adjust for
the two dimensions in the clutch actuator rod as
shown in the PTO Clutch Engaged and PTO
Clutch Disengaged illustrations.
Adjust the bolt head clearance [1/4 to 3/8 in. (6.35
to 9.53 mm)] rst (clutch engaged), then adjust
uncompressed spring length (clutch disengaged).
The spring must be adjusted to an uncompressed
overall length of 2-1/8 in. (54 mm). If adjustments
are needed more frequently than every 100 hours
to maintain the linkage dimensions, it may suggest
problems with pulley wear or belt misalignment.
