Gear pumps in single, dual and triple form, tandem pumps, drive motors and the main, auxiliary and self-level valves get broken down part by part in this 210-page Gehl 4625SX parts catalog PDF (form 907263), covering six variants of the 4525 and 4625 skid loader family. Hydraulics fill over a quarter of the book; exploded views then cover the chassis, planetary axles and chain drive, hand/foot and T-Bar controls, the Quick-Tach lift arm, both engine installs and the bucket, fork and grapple attachments. Every callout ties to a Gehl part number, so you can match the worn piece in your hand before ordering. Order 122733 for the axle nut and 651085 for the 1/2 x 1-3/4 cap screw, then check the O-ring table before a seal kit comes up short. Alone with a down loader, you have nobody to ask. Bookmarks and a text layer find any assembly fast, and printed pages can go to your bench and soak up the grease.

Gehl SL4525, SL4625 Common Problems This Manual Covers
Gehl SL4525 hydraulic pump parts list shows three versions and I can't tell which matches my serial number
Check your serial plate first, then pick the matching standard flow pump page. SN 8827 and later SL4525 (SN 19720 and later SL4625) is on page 23 with gear pump 129093; SN 8563 through 8826 (SN 17248 through 19719) is on page 25 with single gear pump 127294; earlier machines use page 27 with gear pump 121100.
Manual Section: Hydraulic Pump p. 23Can't confirm the right hydraulic filter assembly and element part numbers for a 4625SX versus a 4625
Check the standard flow parts list on page 23 for SN 8827 and later SL4525 or SN 19720 and later SL4625. The 4525 and 4625 use filter assembly 074020; the 4625SX uses 096241, which adds sender/filter restriction 127747. All three take element 074830. Earlier machines on page 27 use element 115259.
Manual Section: Hydraulic Pump p. 23Hydrostatic brake, O-ring and brake solenoid valve part numbers needed when replacing parts at the drive motor
Check the Hydrostatics/Brakes list on page 17, which covers SN 8827 and later SL4525 and SN 19720 and later SL4625. Order brake 129061 (two per machine), O-ring 079289 (four per machine) and solenoid valve 129063. Drive motor is 076484. For the internal breakdown of these assemblies, go to the Hydraulic Components pages starting on page 118.
Manual Section: Hydrostatics/Brakes p. 17Axle nut and planetary cap screw part numbers and torque values needed when reinstalling the drive axle
Check the Axles & Drive Components list on page 13. Axle nut 122733 torques to 150 ft-lbs, and planetary cap screw 651085 (1/2 x 1-3/4) torques to 110 ft-lbs. Both values apply to all models in this book. Cross-check other fastener grades against the torque tables on page 209.
Manual Section: Axles & Drive Components p. 13Can't identify the suction hose, strainer and oil cooler part numbers on the standard flow pump
Check page 23 for SN 8827 and later SL4525 or SN 19720 and later SL4625. Suction hose 114415 (1 x 80), strainer 114715 and oil cooler 128315 are common to the 4525, 4625 and 4625SX. Earlier serial ranges on pages 25 and 27 list different oil coolers, so read the footnote letter beside each part number before ordering.
Manual Section: Hydraulic Pump p. 23High flow case drain filter and triple gear pump part numbers missing from the standard flow pump pages
Check the High Flow list on page 31, which covers the 4625DX at SN 19720 and later. Order triple gear pump 129308 and case drain filter assembly 122756. Main filter assembly 096241 takes element 074830 and sender/filter restriction 127747; a second element, 048959, is also listed. DX units from SN 17248 through 19719 start on page 33.
