The Thunder Stroke 111 uses a single cam chain
system to drive a centrally located camshaft (intake).
The central camshaft uses a gear drive to turn two
outer camshafts (exhaust). Each cylinder is equipped
with two valves that are opened and closed via self-
adjusting hydraulic lifters and pushrods.

SSEERRVVIICCEE NNOOTTEESS

• This chapter covers service of the cylinder heads,

camshafts, cam chain and tensioner, cam chain
guide and roller / rocker arms.

• Refer to Engine / Cooling / Exhaust chapter for

engine removal and installation.

• If cylinder heads are removed the cylinder base

gasket must be replaced also.

• Mark and store all mating parts for correct engine

assembly.

• Use Moly Assembly Paste - P/N: 2871460 or Indian

Motorcycle Synthetic 20W/40 Engine Oil to
lubricate parts where indicated.

• Handle and store all parts in such a way that they

will not be damaged or contaminated.

• Some fasteners have a pre-applied locking agent,

and must be replaced if loosened or removed.
Always replace fasteners that have a pre-applied
locking agent or as directed in this service manual.

• There are some precision machining steps to be

performed in this section. If you are not sure of your
capabilities in these areas, have a competent
machinist perform these operations.

• Valve guide and seat reconditioning should be

performed by a technician proficient in cylinder
head reconditioning techniques using high quality
equipment with grinding stones. Do not attempt
cylinder head repair without the proper equipment
or experience in cylinder head reconditioning
techniques.

• The intake and exhaust valves cannot be re-faced.
• Cleanliness of parts is critical to engine life and

accurate parts inspection. Use clean solvent to clean
all disassembled parts. Dry parts with compressed
air and lubricate before engine inspection and
engine assembly.
