AUSA C 300 H Parts Catalog – Factory OEM Parts Breakdown

I’ve lost count of how many times I’ve seen a mechanic order the wrong coupling because he used a third‑party parts list. That mistake costs time, money, and sometimes a safety hazard when a brake line fitting doesn’t match. The AUSA C 300 H Parts Catalog stops that guessing cold. This is factory‑original documentation – not a reprint, not a scan of a scan. It comes straight from AUSA’s own parts database, with the same exploded diagrams and part numbers their dealers use. 148 pages of clear, numbered views that show you exactly which bolt, seal, or filter goes where. If you work on this forklift, you need this book on your bench or tablet.

Engine Section: USA Version and Standard – Exploded Views

The manual splits the engine into two complete subsections: “Engine (USA Version)” and the standard “Engine” section. That’s not a typo – AUSA ran different emission setups, and the parts differ. On page 3 you’ll see the USA Version with a V3300 – E2B – AUSA complete diesel engine, turbo, fan, heater, and all the fasteners. Every item has a reference number and a part number like 57.02100.00. No more hunting through vague diagrams. The standard engine section (page 5) uses a Kubota V2003-TE diesel. Both include the stop solenoid, oil filter cartridge, V‑belt, alternator, and starter. If your customer’s C 300 H has the USA package, you won’t accidentally order the wrong coupling or gasket.

What Part Numbers Are Listed for the Transmission?

This catalog covers the transmission in fine detail: reduction box, inching pedal, front axle differential, casings, reduction, brakes, and steering drive axle (two parts). Each subsection gives you the factory reference number next to the component. For example, the reduction box has its own exploded view with part numbers like 51401. The brake section lists shoes, springs, cylinders – everything. If you’re rebuilding a C 300 H axle, you can literally point to the diagram and say “I need that bearing.” No cross‑referencing a dozen aftermarket catalogs. The Fuel section is treated the same way – tank, lines, and components are broken out clearly.

5 Major System Groups You Can Navigate Fast

The AUSA C 300 H Parts Catalog is organized into logical groups: Engine, Transmission, Chassis, Hydraulics, and Machine Operation Tools. Under each group are sub‑sections for every assembly. The bookmarks in the PDF mirror the print layout – you click “Transmission – Reduction box” and you’re there. This matters when a customer is waiting and you need a part number for a leaking reduction box seal. You won’t flip through 148 pages blind. The index at the back lists every component alphabetically. I’ve used parts catalogs where the indexing is a joke – this one works.

Use the Filters Kit Section for Routine Maintenance

Page 2 shows the entire filters kit for the C 300 H – one reference number: KF.57000RE00. That’s it. You order that kit and you get every filter, gasket, and seal needed for a full service. No separate listings for oil, fuel, and hydraulic filters. AUSA packs it all into a single kit. If you’re running a shop that does PM on these forklifts, you should stock this kit. The manual gives you the exact kit number so you don’t have to guess which aftermarket cross‑reference works. And the tool bag and decal sections (page 148) tell you exactly which plates and decals go on the machine for compliance. Safety first – wrong decal can mean OSHA trouble.

Fuel System: Tank, Lines, and Components

The Fuel tank section under “Engine” gives you the tank itself, sending unit, cap, and all attaching hardware. Part numbers are listed with exploded views. If you’ve ever had a fuel leak on a C 300 H and wasted an afternoon finding the correct hose, you’ll appreciate having the factory diagram. The same thoroughness applies to the hydraulic diagram installation – oil pump, valves, filters in line, transmission hydraulics, and controls. The manual even includes the electric installation: lights, acoustic alarm, battery, and switches. All with part numbers. That’s what you get when a manufacturer publishes a real parts catalog, not a generic binder.

Source Authenticity: OEM vs Aftermarket

I’ve been burned by aftermarket parts catalogs that list a “compatible” part that doesn’t fit the AUSA C 300 H. This manual is factory OEM. It was produced by AUSA for their own dealer network. The part numbers in this catalog match the numbers stamped on the original components. If you call AUSA and give them a number from this book, they’ll sell you the correct piece. No cross‑reference noise. I don’t trust anything else for critical parts like brake components or steering assemblies. You shouldn’t either.

Frequently Asked Questions

Does this manual cover the DUPLEX and TRIPLEX mast assemblies?

Yes. The Machine Operation Tools section includes separate exploded views for DUPLEX and TRIPLEX masts – internal mast, port‑forks, pipes, external mast, side shift carriage, and cylinders. Each has part numbers unique to the mast type. The TOC lists them clearly.

Are the USA version parts separate from the standard version?

Yes. AUSA split the engine section specifically because the USA emission package uses different turbo, filter, and coupling parts. Same for exhaust, air filter, and some front axle components. The catalog treats them as distinct subsections so you don’t mix them up.

Can I use this to order the filters kit?

Yes. Page 2 shows the complete filters kit with one reference number KF.57000RE00. Order that and you get all service filters in one box.

What about the hydraulic diagram – are part numbers included for the pumps and valves?

Yes. The Hydraulic diagram installation section covers the oil pump, hydraulic pump, distributor, valves, filters in line, and transmission hydraulics. Every component is listed with its factory part number. If you need a new pump for the C 300 H, this manual gives you the exact number.
