GEHL 1648 Parts Catalog – Factory Specs for Asphalt Paver

If you’ve ever ordered a hydraulic seal kit for a paver and ended up with the wrong size because some aftermarket parts list skipped a revision letter, you know the frustration. That’s why this GEHL 1648 Parts Catalog is worth having on the bench. It’s the factory document – Form 908481, Revision C, dated 01/07 – covering serial number 13100 and before. No reprints, no third-party transcription errors. Just the part numbers and diagrams GEHL used when the machine left the plant.

What You Get in This 80-Page Parts Catalog

Eighty pages of exploded-view illustrations and indented parts lists. The table of contents on page 3 breaks it into sections: Decals, Chassis, Hydraulic Assemblies, Hydraulic Components, and Miscellaneous. Each section shows the assembly and then lists every nut, bolt, and seal underneath it – even those that are not illustrated (like common attaching hardware) are indented below the parent part. Page 2 tells you how to read the serial number plate: stamped on the battery support tray and on the left top backwall plate. Right and left are determined from behind the screed facing the direction of travel – GEHL spells that out so you don’t order a left-hand part for the right side.

Decals and Chassis – Why OEM Part Numbers Matter

Decals get overlooked until a safety symbol peels off or a control label fades. The Decals section lists each decal part number – no guessing which warning label goes where. The Chassis section covers the frame, undercarriage, and mounting hardware. If you need a replacement bolt or bracket, the parts list shows the grade (Grade 5 cap screws unless noted) and finish (cadmium or zinc plated). The inside back cover holds the Hardware Torque Specifications – standard torque values for those fasteners. You do not want to guess torque on a paver chassis; that’s how things come loose on a job site.

How to Use the Filter Reference Chart

Page 3 includes a Filter Reference chart – oil, fuel, air, and hydraulic filter part numbers. For example, engine oil filter is P700113; hydraulic oil filter is 074830. When you call a parts counter, you need those exact numbers. The chart saves you the trip of pulling the old filter and matching it. Keep a copy in your service truck. For more background on engine filtration, check this Wikipedia article on diesel engines – but for real part numbers, use the factory chart.

Hydraulic Assemblies and Components – Get the Right Seal Kit

Hydraulics is where aftermarket catalogs fail most often. The Hydraulic Assemblies section shows the pump, motor, and valve groupings as they come off the machine. The Hydraulic Components subsection lists individual cylinders and their seal kits. Because parts are indented, you can see which seals go with which cylinder in the same exploded view. If the manual lists “Not Sold Separately” (NSS) on a component, don’t try to order it alone – you’ll get the assembly. That’s factory-specific info you won’t find in a generic binder. this Wikipedia article on diesel engines covers engine theory, but this catalog covers what bolts to what.

Torque Values You Can Trust – Inside Back Cover

The inside back cover of the manual lists standard attaching hardware torque values for Grade 5 cap screws. No need to flip to a separate torque chart or guess. For example, a 5/16-inch Grade 5 bolt gets [DATA NEEDED] ft-lb – but the manual gives the exact number. If your application calls for a specific torque not on that chart, the manual notes it in the individual assembly. Safety warning: always use a calibrated torque wrench. I’ve seen guys use a “click-and-hope” and then wonder why the hydraulic flange leaks.

Who Needs This 80-Page OEM Parts Catalog

Owners of GEHL 1648 asphalt pavers – especially small contractors or municipal shops that do their own maintenance. It also helps mechanics who work on multiple pavers and need a reliable reference for part numbers. If you are a home garage enthusiast with a paver, this catalog is the difference between buying the right $8 seal and buying the wrong $80 assembly because you guessed the part number. The manual uses imperial units for all dimensions and torque – consistent with North American equipment.

Source Validity: OEM vs. Aftermarket Parts Lists

This is a GEHL factory document, revision C, printed in the USA. The Table of Contents on page 1, the list of abbreviations on page 2 – all original scans. Aftermarket parts catalogs sometimes re-draw illustrations and drop hardware details. Not here. Every indented part, every “AR” (as required) notation, and every filter reference came from the original GEHL engineering files. If you need to order parts for your 1648 serial number 13100 or before, this is the source. No reprints, no copy-paste errors.

Does this parts catalog include torque specs?

Yes. The inside back cover lists standard attaching hardware torque values for Grade 5 fasteners. Also, any special torques are noted in the individual assembly illustrations.

What serial numbers does this cover?

Serial number 13100 and before. The serial number plate is on the battery support tray and stamped on the left top backwall plate. Page 2 explains how to decode the serial number – the unit number, month, engine, and year code.

Stop hunting through three different websites for a part number that might be correct. Access the Factory Manual and have the GEHL 1648 parts catalog on your tablet or printed out next time you need a seal or a decal. You’ll get the part right the first time.
