9. Install retaining ring onto mounting base making certain dust seal is in place on
filter base. Hand tighten ring (about 1/3 turn) until it "snaps" into the detent. DO
NOT overtighten retaining ring.
NOTE:
The proper installation is indicated when a "click" is heard and a release
of the retaining ring is felt. A plug is provided with the new element for plugging
the used element.

11. Open fuel shut-off valve and bleed the fuel system.
Checking Belt Tensioner Spring Tension and Belt Wear (Automatic Tensioner)
Belt drive systems equipped with automatic (spring) belt tensioners cannot be adjusted or
repaired. The automatic belt tensioner is designed to maintain proper belt tension over the life
of the belt. If tensioner spring tension is not within specification, replace tensioner assembly.
Checking Belt Wear
The belt tensioner is designed to operate within the limit of arm movement provided by the
case stops when correct belt length and geometry is used.
Visually inspect cast stops on belt tensioner assembly.
If the tensioner stop on swing arm is hitting the fixed stop, check mounting brackets (alternator,
belt tensioner, idler pulley, etc.) and the belt length. Replace belt as needed
Checking Tensioner Spring Tension
A belt tension gauge will not give an accurate measure of the belt tension when automatic
spring tensioner is used. Measure tensioner spring tension using a torque wrench and
procedure outlined below:
1. Release tension on belt using a breaker bar and socket on tension arm.
Remove belt from pulleys.
2. Release tension on tension arm and remove breaker bar.
3. Put a mark on swing arm of tensioner as shown.
4. Measure 21 mm (0.83 in.) and put a mark on tensioner mounting base.
5. Install torque wrench so that it is aligned with centers of pulley and tensioner.
Rotate the swing arm using a torque wrench until marks are aligned.
6. Record torque wrench measurement and compare with specification below.
Replace tensioner assembly as required.
