4600 Engine & Hydraulic Set-Up Procedures
4600 ENGINE & HYDRAULIC SET-UP PROCESS IN TEST & ADJUST POSITION
Step 1. Check fluid levels.
• Engine Oil Capacity: 5 Quarts
• Hydraulic System Capacity: 3 & 1/2 Gallons
• Cooling System Capacity: 2 & 3/4 Gallons of 50-50 mixture ethylene glycol &
water
Step 2. Adjusting the neutral lock switch
• The neutral lock switch (023002) can be damaged if not properly adjusted. To
insure proper adjustment, put the front neutral lock (467811) in the down
position. Check the switch to make sure both switch boot nuts (023044) and
switch boot (023051) are installed. With the switch loosely installed in position,
begin to move it upward until you hear the switch click. Lock the switch boot in
position with switch boot nuts. Continue to hold switch in this position and
tighten the switch mount bolts and nuts. Warning: the switch can be damaged
by overtightening. After tightening the switch mount fasteners, check the
installation by opening and closing the front neutral lock lever several times to
make sure the switch is clicking and that it is not being forced down past its
travel length.
Step 3. Engine speed setting
• Engine speed is pre-set at factory.
• Check throttle control to make sure it is in the correct positions with respect to
the engine speed specifications.
+ Idle = 900-1000 RPM’s
+ Maximum = 3100-3200 RPM’s
• Check speed with pump disengaged.
Step 4. Check the rear neutral lock (483735) to be sure it is free to fall into the down (locked)
position.
Step 5. Fill and Flush the Hydraulic System
Step 6. Steering Lever Adjustment
• Check and set measurement for the neutral positioning linkage. Do not tighten
the two front nuts on the threaded rod (766303).
• After flushing the hydraulic system, the hydraulic oil will be sufficiently warm to
make the final steering lever adjustment.
• Lock the steering lever into position using front neutral lock (467811) and rear
neutral lock (483735).
• If the wheels rotate, loosen the jam nuts on the turnbuckles. Adjust the
turnbuckles until the drive wheels do not rotate either clockwise or counter-
clockwise. Retighten the turnbuckle jam nuts.
• Tighten the two front nuts on the threaded rod (766303) making sure the rod
does not shift position. Warning: make sure all locking nuts and fasteners are
tight on turnbuckles.
