JETStream TwinForce Series - Changing PTO Oil; Checking Belt Tension

Operation Manual
Changing PTO Oil
1. Place a container below the PTO large
enough to capture the oil in the PTO case
(26 oz) (0.77 L).
2. Remove the drain plug (Figure 135) and
allow the oil to fully drain from the case.
3. When the oil has drained, install the drain
plug.
4. Remove the breather and ll with 10W40
synthetic oil until it begins to show in
the site gauge. Continue adding oil slowly
once visible in the site gauge so as not
to overll. The oil is slow to drain into the
reservoir.
5. Install the ll plug.
Checking Belt Tension
1. Disengage the clutch and stop the engine.
2. Open the access cover on the belt guard.
3. Locate the decal on the cover to nd the
correct belt tension specication.
4. Adjust the deection O-ring (Figure
137) on a belt tension tool for the proper
deection as specied on the decal.
Slide the force O-ring to the bottom of
the scale. Use a ve barrel tension tool if
power bands are used on your unit (Figure
138).
5. Position the tension tool in the middle
of one of the belts mid-way between belt
pulleys. Press on the tool until the deec-
tion O-ring is even with the adjacent belt.
On ve barrel tensioners, press until the
gauge plate (Figure 138) touches the adja-
cent belt.
Note: Power bands are ve times the
single belt force.
6. Release pressure and inspect the reading
at the bottom edge of the force O-ring(s)
(Figure 137) on the tension tool. Adjust the
!!
CAUTION
Belts must be adjusted properly. Improper
adjustment can lead to belt slippage and failure,
or PTO bearing damage caused by excessive belt
tension.
