Buying Guide
Clark Part Sourcing Guide for Forklift Fleets
Source the right Clark part the first time. Cross-reference numbers, verify fitment and cut downtime with BJT's 150,000+ SKU aftermarket catalog.
A Clark part that arrives with the wrong bore, the wrong spline count or the wrong seal profile costs more than the invoice price — it costs the shift. For fleets running Clark trucks alongside Linde, Toyota, Nissan, Doosan, Mitsubishi, Hyundai, HELI, Hyster, Yale, Komatsu and TCM units, the real problem is rarely availability. It is identification. This guide covers how to read a Clark part number, which assemblies fail most often, and how to buy Clark forklift parts online without gambling on fitment.
BJT Forklift Parts stocks more than 150,000 SKUs across engine, transmission, hydraulic, brake, electrical and mast categories, with ISO/CE certified manufacturing and 20 years of export experience to 150+ countries. The catalog is built around the numbers stamped on the components you are actually replacing.

How to Identify a Clark Part Before You Order
Clark equipment spans several decades of production, and the same functional component can carry different numbers depending on the series and build year. Before searching, collect three pieces of data: the truck's model and serial plate, the number cast or stamped on the failed component, and a photograph of the mounting interface.
Reading the number on the component
Most Clark-specification numbers follow a numeric string format, often beginning with zeros. A hydraulic pump may appear as 0009810460-O-1276, 0009812126 or 0009812527 depending on the variant. A diesel filter can be listed as 0009830525 or 0009831660. These are not interchangeable guesses — they are distinct part identities, and ordering the wrong suffix is the single most common cause of a returned shipment.
When the number is illegible
Corrosion and oil film destroy stampings. In that case, work from the assembly outward: identify the parent assembly (for example a brake cylinder 0365042300 or 3355045402), then match by bore diameter, port orientation and stroke. Our technical support team can cross-reference from photographs and dimensions when the number is gone.
High-Failure Clark Part Categories and What to Stock
Downtime clusters in predictable places. Across Clark fleets, the components below account for the majority of unplanned stops. Keeping one or two of each on the shelf is cheaper than an air freight shipment.
- Brake system: brake cylinder, master cylinder, brake cable, brake line, brake pad, brake drum, brake pedal pad and brake potentiometer assembly.
- Transmission and driveline: torque converter oil seal, pressure converter, internal ring gear, V-belt, universal joint and drive shaft flange.
- Hydraulics: hydraulic pump, piston rod assembly, center cylinder repair kit, O-rings and the tandem pump with steering priority valve.
- Cooling and engine support: radiator overflow tank, upper and lower water hose, breather cap, pre-filter and diesel filter.
- Electrical: ignition switch assembly with 2 keys, main harness, LED headlight assembly and LED blue light.
- Mast and attachment: side shift slider, side shift roller, side shift liner, fork pin lever, right and left rings.

Clark Part Cross-Reference Table
The table below maps common functional groups to representative BJT part numbers. Use it as a starting point, then confirm against your truck's serial data. Numbers shown are catalog references, not universal fitments.
| Function | Representative part numbers | Typical failure signal |
|---|---|---|
| Hydraulic pump | 0009810460-O-1276 / 0009812126 / 0009812527 | Slow mast lift, whine under load |
| Brake cylinder | 0365042300 / 3355045402 | Soft pedal, fluid weep at the wheel |
| Master cylinder | 12195101200 / 41585002400 | Pedal sinks to floor, poor hold |
| Diesel filter | 0009830525 / 0009831660 | Hard starting, power loss |
| Air filter | 0009839002-O-350 / 0009839022 | Restricted intake, black smoke |
| Ignition switch | 0009730212 / 7915492601 / 7915492622 / 7915492618 | No crank, intermittent start |
| Side shift cylinder | BZ141030714C | Drift or hesitation in sideshift |
| Steering cylinder seal kit | 0009608030 | External seepage, wander at speed |
OEM-Spec Aftermarket vs Used Clark Forklift Parts
Used Clark forklift parts have a legitimate place — typically for obsolete series where new tooling no longer exists, or for non-critical body panels and brackets. The economics change quickly for wear items. A used hydraulic pump with unknown hours can fail within weeks and take a seal kit and a shift with it.
For anything in the brake, hydraulic or transmission circuit, aftermarket parts manufactured to OEM dimensions are the more defensible choice. The decision criteria are straightforward:
- Wear surface involved? Buy new. Brake drums, cylinders, pumps and bearings fall here.
- Safety-related? Buy new. Brake assembly 61393300200, brake pad 1135040302 and brake cable fall here.
- Cosmetic or structural with no wear interface? Used may be acceptable if inspected.
- Obsolete series with no new supply? Used or custom fabrication, verified dimensionally.
As a parts supplier working across multiple OEM platforms, we see the same pattern in every market: the cost of a premature failure almost always exceeds the saving on a used wear part.

Choosing a Clark Forklift Parts Supplier
Price comparison is the easy part. The harder questions are about identification support, documentation and lead time reliability. A supplier worth keeping should be able to do all of the following:
- Cross-reference from a photograph, a casting number or a measurement set.
- Confirm the exact suffix variant before shipping — for example distinguishing 0009830525 from 0009831660.
- Supply ISO/CE certified components with traceable manufacturing origin.
- Quote consolidated shipments when you are ordering across multiple categories.
- Support special fork requirements, including spark-retardant brass-clad forks, stainless-steel-clad forks and solid stainless-steel forks for hazardous or corrosive environments.

Frequently Asked Questions
How do I find the right Clark part number for my truck?
Start with the model and serial plate, then read the number stamped or cast on the failed component. Where the number is unreadable, measure the mounting interface and bore, and cross-reference through a supplier's technical desk. Numbers such as 0009812126 and 0009812527 look similar but are not interchangeable.
Are aftermarket Clark forklift parts as good as OEM?
A correctly specified aftermarket part manufactured to OEM dimensions performs equivalently in most applications. The critical variables are material grade, heat treatment and dimensional tolerance. BJT components are ISO/CE certified and produced to original specifications, which is why they are used across 150+ countries.
Should I buy used Clark forklift parts to save money?
Only for non-wear, non-safety components or obsolete series where new supply has ended. Used brake, hydraulic and transmission parts carry unknown service hours and frequently fail early, erasing the initial saving through repeat labour and downtime.
Send your Clark part list — numbers, quantities and truck models — to our team through the RFQ form and we will confirm fitment, flag any ambiguous suffixes and quote consolidated shipping. If you are unsure about a number, include a photograph; identification support is part of the service, not an add-on.
