7-8. Adjustment of the neutral position of piston pump
A. Adjustment of neutral position
. When the machine will not stop even if the traveling lever is released, adjust the neutral position in the manner shown below.
Secure the machine so that the rubber crawlers at right and left will be lifted above the ground, and release the side
brake. (When the rubber crawler is out of place, lift the sprocket above the ground.)
After loosening the mounting bolts (Fig.B), start the engine and move the neutral lever right and left to find the neutral
position.
The engine is running. Be careful of the rotating parts and hot parts.
When the neutral position is found, tighten the mounting bolts, and recheck that the machine is in the neutral position.
Adjustment of the neutral position is finished.
Then while keeping the machine in the neutral position, pull the side brake and make adjustment so that the lock shaft of
the traveling lever is set in the grooves of the neutral stopper. (Fig.A)
Loosen the lock nuts of the M10 rods at right and left. (Fig.A: 4 locations in total)
Rotate the rods to adjust the length of them and make adjustment so that the lock shaft will be set naturally in the
grooves.
Confirm appropriate setting of the lock shaft and grooves by repeat of lock and unlock of the side brake several time.
After adjustment, tighten the lock nuts and check again the locational relationship between the lock shaft and grooves.
Now all the processes are finished.
. If the side brake cannot be pulled (the lock shaft and grooves are not in position) although the machine is at rest when the
traveling lever is released, continue operations from .
B. Q&A about neutral position
Q : What will happen when the neutral position is not correct?
A : Even if the operation lever is released in an emergency, the machine will not stop, which is very dangerous.
Q : What will happen when the lock shaft and groove are not in position.
A : You cannot pull the side brake, and you cannot park the machine correctly. When you pull the side brake forcibly and
align the lock shaft with the grooves by force, the traveling machine will be forcibly stopped by the brake; therefore, the
relief valve will be activated, raising the oil temperature suddenly.
When the oil temperature rises, the hydraulic equipment will be damaged.
