Tiger BENGAL BRUTE JD 62-6420 - Manual (Page 35)

ASSEMBLY
Assembly Section 2-3
FRONT CRANKSHAFT PULLEY
Tiger has found that the front crankshaft pulley used by JD will not allow for the installation of a
front drive system. You will need to order a different pulley, washer and bolt from John Deere to allow
for a front drive to be installed on your tractor.
Inspect the front pulley on your tractor to verify you have the correct pulley needed to mount
the spacer plate. If your pulley has the (4) four holes needed to mount the spacer, your pulley is
the correct one needed. If your pulley does not have the (4) four holes in the pulley, you will need
to order the correct pulley, washer and bolt from John Deere.
PARTS REQUIRED TO PURCHASE FROM JOHN DEERE:
Pulley from JD - R516320
Washer from JD - R517237
Bolt from JD - R516648
Torque on the pulley bolt with locktite is 369 lb-ft.
Solution:
1. Clean nose of crankshaft using TY16285 clean and cure primer.
2. Apply a light 2-3mm bead of TY15969 retaining compound around the leading edge of the
crankshaft nose.
3. Dip damper mounting capscrew in clean SAE30 engine oil (Always use a new capscrew).
4. Position damper/pulley on the crankshaft and thread capscrew up tight (do not rely on the
capscrew to pull the pulley straight onto the taper).
5. Tighten capscrew to specification 500Nm (369lb-ft) (the engine will most likely have to be
pinned).
6. Measure run-out on the pulley, spec is 0.003” or less.
