Maintenance Instructions ADJUSTMENTS75Forward Speed Control Stopand Steering Lever AdjustmentSteering Lever End Play Adjustment - Step 21. Position the FSC lever to the most FORWARDposition.2. Loosen the adjustment nut on each steering le-ver actuator until end play develops betweenthe lever actuator and the adjustment nut (slid-ing on transmission control rod).3. Hold the actuator back as shown (against thespring pressure) and tighten the nut to the pointwhere the end play is removed and then tight-en two additional turns.IMPORTANT: If the adjustment nut is too loose(end play exists) excessive loads are placed ontransmission internal control stops. If the adjust-ment nut is too tight (preferred condition), the max-imum forward travel speed is reduced.Neutral Function Adjustment - Step 31. Move the FSC lever to the NEUTRAL-PARKposition (rear travel limit).2. Start the engine (operate first at idle and thennormal operating speeds) and check for move-ment of the drive wheels.NOTE: If the engine will not start, check and ad-just the neutral safety switch (see item 4 below).Neutral Function Adjustment3. If drive wheels are moving, stop the engine andadjust the FSC neutral stop by adjusting theFSC actuator clevis (see Neutral Function Ad-justment photo for clevis location). If the drivewheels are moving backward, remove the cotterpin and clevis pin and screw the clevis forward.If the drive wheels are moving forward, screwthe clevis backward. Restart the engine andcheck for wheel movement (several “trial and er-ror” adjustments may be required). At this pointit may not be possible to adjust both wheelsstationary since the differential adjustment hasnot been made. (This is covered by the StraightGround Travel Adjustment - Step 4.) In thiscase, the neutral adjustment should be made forone wheel stationary and the other moving for-ward slightly.4. Check and adjust the neutral safety switchfor closure and function with the FSC in neutral(the engine will not start when the switch isopen). Use panel nuts on the switch body toadjust switch position for closure in neutral.
