Note: The installation procedures which follow assume that the camshaft has been modified
appropriately and that the engine has been disassembled and cleaned as it would be for a
normal timing set change.
YOU WILL NEED:
TOOLS:
1/4" Hex Bit Socket or Hex Wrench
Torque Wrench
Hammer
Sleeve to fit over crankshaft for installing Crankshaft Sprocket
Degree Wheel (Optional, but Recommended)
SUPPLIES:
Assembly Lube or Camshaft Lube
Thread Locking Compound (LockTite7 #271 or equiv.)
1.
Prepare the Engine. Loosen all rocker arms so that the camshaft can rotate freely.
2.
Clean everything! Make sure that the engine mounting surfaces and timing set
components are as clean as possible. The life of the chain and sprockets depends on it.
3.
Mount the Crankshaft Sprocket. Select the appropriate keyway for the camshaft timing
baseline desired. We recommend the Standard Timing position, which used the round
timing mark and round keyway mark. Carefully tap the sprocket onto the crankshaft using
a sleeve to protect the sprocket. Make sure that the sprocket is fully seated on the
crankshaft. Rotate the crankshaft until the appropriate crankshaft sprocket timing mark is
in the 12:00 position.
4.
Insert the Hex-A-Just
®
Timing Bushing. Insert the offset bushing (with the Hex hole)
into the slot in the camshaft sprocket hub. Rotate it with a 1/4" Hex Wrench so that the
timing mark on the bushing points away from the center of the hub (Figure 1). The
Hex-A-
Just
®
Adjustable Timing Bushing is infinitely
adjustable so you can fine adjust your engine's
CAMSHAFT TIMING to EXACTLY WHERE YOU
WANT IT
.
5.
Mount the Camshaft Sprocket. Loop the chain
over the camshaft sprocket. Align the camshaft and
crankshaft timing marks and loop the chain around
the crankshaft sprocket. Lift the camshaft sprocket
into place on the camshaft, with the
Hex-A-Just
®
Bushing in place. Be sure that the timing mark aligns
