When your 26MRT is stuck at half height waiting on a part, the 130 pages of this JLG 26MRT parts manual PDF (OEM catalog 3120893) put the exact part number in your hand before the dealer picks up the phone. Exploded views break the drive motor, piston pump, and lift cylinder assemblies down fastener by fastener, each callout keyed to an itemized list so the seal kit you order is the one that fits. Serial number breaks separate early and late arm guards, controllers, and cylinders, and dedicated schematics cover both the Vanguard gas and Yanmar diesel electrical systems along with the standard hydraulic diagram. Ordering harness components, match the 16/3 electrical cable at 6 ft (1.8 m) or the 2.4k ohm, quarter watt resistor straight off the diagram list. Wrong part in the box, another day the lift sits. Download the bookmarked, keyword-searchable file and put the 26MRT back in the air.

JLG 26MRT Common Problems This Manual Covers
JLG 26MRT won't drive until hydraulics warm up, need part numbers for drive circuit valves and motor
Check the hydraulic schematic on page 100 and identify each valve and drive component in the circuit, then match those callouts against the hydraulic parts diagram on page 46 for part numbers. Verify serial number ranges in the parts list before ordering; if you also need the drive enable wiring, the 16/3 cable on page 19 runs 6ft/1.8m.
Manual Section: Hydraulic p. 100Machine powers up but won't move, can't identify the drive and steer switch part numbers
Check the wiring diagram on page 108 and trace the drive enable circuit to the switch that's dropped out, then pull the matching part number from the electrical parts lists. Measure your existing cable run before ordering: the 16/2 electrical cable on page 20 is listed at 9ft/2.74m, and the 16/3 on page 19 at 6ft/1.8m.
Manual Section: Electrical p. 108Intermittent lift and drive functions, need replacement controller connector and wiring harness part numbers
Verify the component values on page 116 before ordering controller harness parts: the capacitor is 100mf/25V and the resistor is 2.4k Ohms 1/4 Watt. Match connector part numbers from the harness and cable assemblies listings, and inspect your existing harness pins for corrosion so you replace the right leg of the circuit.
Manual Section: Harness and Cable Assemblies p. 116Not sure which service parts to stock on the shelf for a rental fleet scissor lift
Check the recommended service parts stock lists on page 125 for the standard and variable parts the factory expects you to keep on hand. Stock hydraulic oil, drive and steer switches, and common cables; the Flex-Trim on page 24 comes in a 9ft/2.7m length, so one piece covers most edge repairs.
