Trowel Gearboxes
See Graphic: wc_gr000156
Check the gearboxes for the correct oil level after every 20 hours of
operation. Change the gearbox oil every 300 hours.
To check the oil level:
Each CRT gearbox is equipped with two oil fill plugs. Remove one
gearbox oil fill plug
(b)
. If the level is below the threads of the oil fill plug
hole, add synthetic gear oil through the opening. DO NOT overfill.
Wipe the threads dry on both the gearbox and the oil fill plug, apply
Loctite 545 or equivalent to the oil fill plug threads, replace the oil fill
plug and torque to 16–20 Nm (12–15 ft.lbs.).
NOTICE
: DO NOT
mix types of gear oil.
DO NOT
overfill the gearbox
with oil. Damage to the gearbox may occur if oils are mixed, or if the
gearbox is overfilled. See
Technical Data
for oil quantity and type.
To change gearbox oil:
5.2.1
Place a container of sufficient capacity (approximately 3.8 l [1 gallon])
under each gearbox.
5.2.2
Remove the gearbox oil drain plug
(c)
and allow the oil to drain out. It
may be necessary to remove the gearbox oil fill plug(s) to facilitate
draining. After most of the oil has drained out, tip the back of the trowel
upwards to allow the remaining oil to drain out.
5.2.3
After all the oil has drained out, wipe the threads dry on both the
gearbox and the oil drain plug, apply Loctite 545 or equivalent to the oil
drain plug threads, and replace the gearbox oil drain plug.
Note:
Dispose of used gear oil in accordance with environmental
protection legislation.
5.2.4
With the trowel level, fill the gearbox with approximately 1.83 l (62 oz.)
synthetic gear oil through the oil fill plug as described above.
5.2.5
Wipe the threads dry on both the gearbox and the oil fill plug, apply
Loctite 545 or equivalent to the oil fill plug threads, replace the oil fill
plug(s), and torque all plugs to 16-20Nm (12–15 ft.lbs.).
Each gearbox has a pressure relief valve
(a)
which can become
clogged over time and should be replaced every 300 hours. Failure to
replace the valve can result in oil leakage from the gearbox shaft seals.
