All weather drive
roller installation instructions
All parts included for change-out including 3/16" drill
Remove tug handle with drill from
transmission receiver. It is easiest to perform the installation with the
transmission clamped securely up-side down on a work bench.
Rotate existing drive roller and
sprocket as necessary using a 3/8” ratchet in the tug drive socket before
removing split pins. BE SURE THAT YOU HAVE
AT LEAST 2" CLEARANCE ON OPPOSITE
SIDE for removal of
pins. Note position of all components before removal.
Remove existing drive
roller and sprocket by driving out split pins using a 5/32" hardened drift
pin at least 3" long. Tap drive
axle out, discard.
Re-install new drive axle, new drive
roller and existing sprocket and chain. Use a screwdriver between drive roller
and sprocket gently pressing sprocket and drive roller against bearings. Align axle ends flush with bushings.
The pre-drilled holes in both drive
roller and sprocket provide proper alignment for drilling holes through the new
axle. We advise using the high speed
setting on your drill and the use of cutting oil for drilling these holes.
Drill a 3/16" hole through new
axle for drive roller first. Double
check that it is flush to the bushing and that the axle is flush to the outside
of the bushing. Install split pin fully
using a hammer and punch.
Drill a 3/16" hole through new drive
axle for sprocket. Double check that it
is flush to bushing. Install split pin fully using hammer and punch. If you have a 9
tooth drive sprocket, bore a fresh hole at 90˚ from existing hole.
Drill holes slowly and
maintain a firm grip on your drill. As the drill bit breaks through drilling
the hole in the drive axle it will want to suddenly pull down. A broken drill
bit is extremely difficult to remove.
