3l74 YAMAHA PHAZER STD START ENGINE TENSIONER
INSTALLATION INSTRUCTIONS
This engine tensioner is designed to keep the engine from twisting under power, causing misalignment of the clutch sheaves. By keeping the engine from twisting, the clutches stay aligned, belt life and efficiency are improved.
Remove clutch guard.
Align clutches to factory specifications and tighten motor mount bolts.
Install hook around back of LH front motor mount on the clutch side.
Turn the jam nuts on each side of the compression bushing washers to align tensioner bracket to the frame in front of the motor mount.
Note: ‘84 uses 2 mounting bolts.
‘85 uses 1 nut and 2 bolts.
‘86 and newer uses 3 nuts.
On 84 models we recommend installing a bolt in the top hole through the frame. Also on 84—85 models you will have to remove the spark plug holder and put the tool kit in the trunk.
Tighten the front nylock nut until the tensioner hook is snug and then turn approximately 1/2 turn tighter. Then tighten the rear jam nut securely.A sleeve inside prevents over tightening. Check that the tensioner hook is snug and readjust as necessary.
