Assembly Instructions
NOTE: If there is a gap between the rear
upright mount and the chassis frame, install the
optional shim (P/N 8400-39) for best t.
NOTE: For Model T25i only, reinstall the fuel
pump module at the same time.
23. Using the tapered punch align the front holes
of the right rear mount holes and install a bolt
(from the inside to outside) through the rear
precleaner mount, Hi-Dump
®
and chassis. Install
nut nger tight. Remove the tapered punch and
install a bolt (from outside to inside) through the
front mount holes of the chassis, Hi-Dump
®
and
rear precleaner mount and install nut nger tight
(using existing hardware removed earlier).
24. Using the tapered punch, align the holes where
the two (2) bumper upright supports connect
to the chassis and install existing hardware, as
shown in Align Bumper Upright Supports to
Chassis photo.
IMPORTANT: A production change was made
at tractor S/N 2018-151222, and A21 S/N 2018-
5402 that enlarged the hole from 3/8 in. to 7/16
in. It is possible that the Hi-Dump
®
kit bumper
and the tractor chassis could have differing hole
dimensions. If hole dimensions are different,
drill the smaller hole to 7/16 in.
