Bobcat Forklift Inching Valve A373593 — D20GP / D25GP / D30GP Powershift Transmission
The A373593 inching valve (also cross-referenced as 410116-01577) is the clutch modulation valve for Bobcat D20GP, D25GP, and D30GP powershift transmission forklifts. This spool-type valve controls the hydraulic pressure applied to the forward clutch pack through the inching pedal circuit — when the operator depresses the inching pedal, the valve progressively bleeds clutch pressure, allowing the forklift to creep at extremely low speed for precision positioning. The A373593 is a direct bolt-on replacement for the Bobcat D-GP series transmission control valve body and does not require adapter fittings or hydraulic circuit modifications.
This valve fits all three D-GP models (2-ton D20GP, 2.5-ton D25GP, and 3-ton D30GP) in both diesel and LPG configurations — the transmission control valve body is identical across the series. The A373593 uses a hardened alloy steel spool in a cast iron body with precision-lapped bore clearance to maintain consistent pressure modulation across the full pedal travel range. The valve’s internal return spring provides positive spool return when the inching pedal is released, ensuring the clutch pack re-engages fully without residual drag. Unlike the mechanically simpler inching valves on manual-transmission forklifts, the A373593 must maintain a precise pressure curve to prevent clutch chatter during low-speed maneuvering with heavy loads.
Installation requires draining the transmission fluid, removing the control valve cover plate, and replacing the valve as a complete cartridge — the internal spool and seals are not separately serviceable. Always flush the transmission cooler circuit and replace the filter when replacing an inching valve, as spool wear debris circulates through the hydraulic system.
