GEHL AWS46, AWS36 2008 Service Manual – Factory OEM Specifications

If you’re working on an AWS36 or AWS46 all-wheel-steer loader and you’re relying on aftermarket specs or old guesses, you’re costing yourself time and risking a comeback. I’ve seen guys snap bolts because they used the wrong torque sequence. This manual is the factory-issued documentation from GEHL, printed in 2008, covering both models across 208 pages. It’s what the dealer techs had open on the bench. The GEHL AWS46, AWS36 2008 Service Manual gives you the real numbers – not some third-party copy.

Hydrostatic Drive and Work Hydraulics: Factory Procedures

Chapter 1 of this manual gets into the hydrostatic drive and the work hydraulics with four-wheel steering. Page 1-1 lays out important information about this manual, but the real meat is in the specifications chapter. For the hydrostatic drive, you get the charge pressure specs and flow rates. No guessing – if the machine won’t move, you go straight to the test points. The hydrostatic drive eliminates the need for a clutch and traditional Manual Transmission, but the service procedures are just as critical.

Specifications Chapter: What You Get on Page 2-0

Page 2-0 lists the frame types and models, engine specs, and power train data. This is where you find the torque values for the wheel lug nuts, the hydraulic pump displacement, and the axle ratios. I’ve had to order parts based on serial numbers from page 1-4, and this manual gives you the component numbers for the engine, hydraulic pump, and motors. Without those numbers, you’re ordering blind. Pair this service manual with the GEHL AWS46 Operator’s Manual 2009 for daily operation checks.

Where Are the Serial Numbers Located?

The manual tells you exactly where to find the serial number on the frame, the cab number, engine number, hydraulic pump number, and both axle numbers. See page 1-4 for the locations. I’ve seen guys chase the wrong machine because they didn’t match the cab number to the service bulletins. This manual stops that. The Gehl AWS36 All-Wheel-Steer Loader Operator’s Manual also references these same locations for routine maintenance.

3 Reasons to Choose OEM Documentation

First, the torque specs come straight from GEHL – no aftermarket guesswork. Second, the wiring diagrams match the actual harness colors – try that with a reprint. Third, the safety decal locations and warnings are included starting on page 1-6. Aftermarket manuals skip that stuff. If you want to keep the loader running and void no warranties, you use the factory book.

Get the Right Torque Data

Page 2-0 of this manual lists the engine torque specs for the mounting bolts and the drive train fasteners. You don’t need to guess between ft-lbs and in-lbs – it’s all there. I always keep a torque wrench calibrated to those numbers. If you’re rebuilding the hydrostatic drive, the charge pump pressures are in the specifications chapter.

Frequently Asked Questions

Does this manual cover the AWS36 only or both models?

Both models. The manual covers AWS36 and AWS46 in one volume.

What torque specs are included for the engine?

The specifications chapter on page 2-0 includes engine mounting bolt torque, wheel lug nut torque, and hydraulic pump flange bolt torque. You also get the charge pressure range for the hydrostatic drive. I’d recommend checking page 2-0 before any major fastener removal.

Are wiring diagrams included for the steering system?

Yes, the manual includes wiring diagrams for the instrument panel, multi-functional lever, and switch panel – see chapter 1 overview on page 1-10. The diagrams show wire colors and connector pin-outs, which is more than aftermarket manuals provide.

How do I jump-start the engine according to the manual?

The jump-starting procedure is on page 1-13. It specifies connecting positive cables first, then negative to a ground point away from the battery to avoid sparks near the terminals. The manual also includes warnings about the backup warning system option and the manual throttle option. If your machine is equipped with the oil and fuel pre-heater option, that’s on page 1-12. I’ve seen battery explosions from improper hookup – this manual gives you the factory-recommended sequence to avoid that. Do not skip reading the safety instructions on page 1-13 before jumping.

Whether you’re a fleet mechanic or a one-man shop, having the factory documentation on hand means faster diagnostics and fewer callbacks. If you’re used to working on a Manual Transmission, the hydrostatic system here works differently, but the manual walks you through every check. Access the Factory Manual from AutoRepairManuals and keep it on your tablet or printed out in the bay.
