GEHL HL 3030 Parts Catalog

You’ve got a GEHL HL 3030 Parts Catalog in your hands. That means you’re tired of holding up a job because the part number you ordered doesn’t match the bracket in front of you. This 56-page factory document is the only reliable way to match the metal on your bench to the number in the catalog. Aftermarket reprints blur the lines – this one doesn’t.

Every section is laid out by system, not guesswork. Need the fuel system parts? Page 9. Need the full drive and axle assembly? Pages 12-13. If you’ve ever pulled a HydraCat apart and found two different hydraulic setups between serial numbers, you already know why the “after Serial No. 1110” and “before Serial No. 1111” splits on pages 18-21 matter. Get the wrong pump because you used a generic index, and you’re eating the return shipping. I’ve seen it happen. Don’t be that guy.

56 Pages of Factory Diagrams for the GEHL HL 3030

Thickness doesn’t mean anything if the info is wrong. These 56 pages are the same pages the GEHL dealers used. The exploded views on page 4 (Engine and Pump) show you exactly how the engine mounts line up with the hydraulic pump drive. Page 5 breaks down every component on that engine – injection pump, alternator bracket, the whole deal. You won’t find a single “reference only” mark. Every callout is a live part number you can hand to the counterman. If you are rebuilding a unit that’s been modified, the Introduction on page 2 explains how the serial number plate is located on the right side lifting arm support. Write that number down before you touch anything.

Engine and Pump: Section Breakdown on Page 4

The Yanmar diesel in the HL 3030 is a workhorse, but when the injection pump seal starts leaking, you need the right seal kit, not a universal O-ring assortment. Page 4 shows the pump-to-engine adapter plate with the exact bolt pattern. For a solid background on how these small diesels operate, check out this Wikipedia article on diesel engines. It’s worth reading when you’re waiting for parts. The Battery and Instruments section on page 6 covers the charging circuit and instrument panel – if your gauge cluster is acting up, that page has the wiring callouts.

Why Does OEM Documentation Matter?

I have seen third-party parts books where the illustration was reversed left-to-right because someone scanned the wrong side. That costs you an afternoon. GEHL printed this catalog on their own press. The Decal Locations page 3 alone is worth the access – if you’re replacing safety decals after a repaint, you need the correct placement. Aftermarket catalogs skip that. This one doesn’t. The Numerical Index on page 2 lets you look up any part number directly if you have the old number. Fast turnaround, no cross-referencing.

Hydraulic System Variations: Before and After Serial No. 1110

Two different hydraulic pump setups exist on the HL 3030. Pages 18-19 cover machines built after serial number 1110; pages 20-21 cover earlier units. Miss that split and you’ll order a pump with the wrong mounting flange. The Oil Pump diagram on page 19 shows the gerotor assembly. The Lift and Tilt Valve schematic on page 27 is where you’ll find the relief valve settings – not torque specs (this isn’t a service manual), but the correct rebuild kit part number is right there. If your loader shares a platform with the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual, some attachment components cross over, but always verify against your serial number.

Order the Correct Attachment Parts

The Optional Attachments section starting on page 33 is where most ordering mistakes happen. The Snowblower pages (42-49) are the thickest part of the catalog – auger, fan, gearbox, chute rotator. If you’re mounting a BH3030 Backhoe (pages 50-53), the subframe brackets are listed individually. You need the manual to know which bracket fits your specific frame serial. The Utility Bucket and Pallet Fork page 35 lists the cutting edge part numbers with thickness specs. Don’t guess – measure what you’ve got and match it to the diagram. This is the only way to avoid the wrong bucket pins or missing shims.

The manual also covers the LT3030 Trailer wiring on page 30 and the Actuator on page 31. Two trailer versions exist (before and after serial 1061) – same rule applies. Use the serial number, not the year of manufacture.

Stop ordering parts blind. Access the Factory Manual and keep the PDF on your shop tablet. When the customer is waiting and you need the right hydraulic filter number, you’ll have it.

Frequently Asked Questions

Does this manual include torque specifications?

No, this is a parts catalog, not a service manual.

What is the difference between the two hydraulic system sections?

GEHL changed the hydraulic pump and oil tank layout starting at serial number 1111. Pages 18-19 cover machines after serial number 1110 (the later version), and pages 20-21 cover machines before serial number 1111 (the earlier version). The pump mounting flange, suction line routing, and oil cooler connections differ between the two. Ordering a pump from the wrong section will result in a part that physically does not bolt up. Always verify your machine’s serial number from the plate on the right side lifting arm support before referencing either section. The same split applies to the LT3030 trailer, which uses serial number 1060/1061 as the cutoff.
