7.4 Check hydraulic oil level: see 5.1.3
7.5 Replenish hydraulic oil: Take precautions to prevent oil spills.
Carefully remove the oil drain plug from the bottom of the hydraulic by
using an Allen wrench. Remove the red top cover of the STrac 700 by
removing 6 bolts. Remove the plastic cap off the top of the hydraulic
tank. This can be done by removing three bolts. Now the hydraulic return
filter can be removed and replaced by a new filter. Mount the cover back
on the filter housing and mount the red STrac 700 cover back in place.
Let all oil drain from the tank into an oil pan. Re-insert the drain plug. Fill
the tank to a level just below the top mark on the oil level stick. Start the
engine and check for leaks. Let the engine run for 1 – 2 minutes and then
stop the engine and check the hydraulic oil level again. If necessary, add
more oil.
7.6 Grease PTO: use a grease gun filled with EP2 grease. Turn the PTO
covers in a way that the grease nipple can be reached through this hole.
Grease 1 x grease nipple of the joint and 1 x grease nipple for the PTO
cover per side. Do not over grease!
7.7 Grease steering pin: Turn the steering boom all the way left or
right. Look straight from the front into the gap between the front wheel
frame and central frame. Here you can see the grease nipple positioned
on a bushing. Grease this nipple. Do not over grease!
7.8 Check and tension V-belts: There are in total 5 V-belts in the drive
lines of the STrac: three for the PTO clutch and two for the side drive.
7.8.1 Check the triple PTO clutch V-belts: Remove the red top cover
of the STrac 700. The three clutch V-belts can be found next to the
engine. If these V-belts start slipping, all V-belts need to be replaced.
This can easily be done by removing the engine. Take out the four bolts
and nuts and bend the motor over forwards to get the pulleys away from
under the V-belts and pump-chain. Replace the three V-belts and re
position the engine again in the opposite way. Make sure the drive line of
the chain and V-belts is aligned. Place the red top cover back in place.
7.8.2: Check the STrac 700 double side V-belt drive: Remove the
black side cover on the opposite side of the engine. It is held in place with
four nuts. Check the V-belt tension and re-tension if necessary. Re-
tensioning can be done on the bottom. Loosen up the two bolts that hold
the lower bearing house. Next use the tensioning nut on the STrac to
tighten V-belts. Re-tighten the bolts which hold the bearing house and
check if the V-belts are not adjusted too tight. Do not over tension the V-
belts as this may seriously damage the bearings.
7.9 Check and re-adjust cables: Cables control the throttle, the
hydrostatic forward-backward movements, and the hydraulic control
valve. It might be necessary to re-adjust these cables. These cables can
only be adjusted under the steering boom. Make sure to make small
changes at a time when adjusting the cable. When these controls have
