Installation Instructions
9-3145B Hex-A-Just® True Roller Timing Set
BEFORE YOU BEGIN: READ ALL OF THESE INSTRUCTIONS FIRST !!!
Note: The installation procedures which follow assume 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 (LockTite® #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 depend 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. Make sure that the number one piston is at top dead center.
