SkyTrak Parts

SkyTrak telehandlers are the definition of rental-fleet workhorses, and their parts situation has one dominating rule: the serial number decides everything. The same steering component can fit an 8042 built before one serial number and not the machine built after it, and SkyTrak parts documentation is written in exactly those terms. This guide covers the model line, why serial breaks matter more here than almost anywhere else, and which components keep these machines working. SkyTrak is a JLG brand, and AirWorx stocks and sources SkyTrak parts from branches in Indianapolis, Fort Wayne, and Warsaw, Indiana, and Flora, Illinois.

Which SkyTrak machines does this guide cover?

The legacy line. The models that built the brand’s reputation and still fill job sites: the 6036, 6042, 8042, 10042, and 10054, named for capacity and reach, so a 10054 lifts 10,000 pounds to a 54 foot boom height. Older 4266, 4270, and 4290 machines are still working too, and parts support for them runs through the same system.

Reading a SkyTrak model number

Model	Capacity	Reach
6036	6,000 lb	36 ft
8042	8,000 lb	42 ft
10054	10,000 lb	54 ft

Current production. JLG continues the SkyTrak line with updated versions of the core sizes. The identification method is identical; only the component revisions change.

Because SkyTrak belongs to JLG, its parts flow through the JLG network, and some components are shared across the wider JLG telehandler family, including legacy Lull machines. If your fleet mixes SkyTrak and Lull, our Lull parts guide covers that side, and one parts call at AirWorx handles both.

Why serial numbers matter more on SkyTrak than almost any machine

Every manufacturer revises machines mid-production, but SkyTrak documentation makes the consequences unusually visible: parts listings routinely specify fitment as “prior to serial number X” or “serial number Y to present,” sometimes with individual serial numbers included or excluded from a range. Axles, steering components, transmission parts, and electrical items all carry these breaks.

The practical rule: never order a SkyTrak part from the model number alone. Two 8042s parked side by side can take different components, and the visible difference may be nothing at all. The complete serial number, read from the machine, is the only reliable key, and with it a parts specialist can resolve most requests in one call.

How do you identify the right SkyTrak part?

The data plate sits in the cab area or on the frame near the cab; record the full model and complete serial number, and if the plate is unreadable, find the serial stamped into the frame. Add the failed component’s own part number when a label or casting shows one, and photos: the component, its connections, its position, and for hoses both end fittings and the routing.

For drivetrain and hydraulic symptoms, note the conditions: does the problem appear loaded or unloaded, in which gear or steer mode, hot or cold. Telehandler diagnosis leans on operating context more than scissors or booms, and a good description shortens it.

Common SkyTrak parts by system

Boom and attachment components. Boom wear pads are the signature consumable, slop, chatter, or noise in the telescope usually means pads, along with boom chains and hoses, quick-attach carriage components, fork pins and hardware, and tilt and extend cylinder parts. Carriage and attachment pins wear on machines that swap attachments often.

Drivetrain and axles. Transmission components and shift selectors, drive shafts, axle assemblies and seals, differentials, and hubs. These machines live on rough ground under load, and the axle and steering end of the machine wears accordingly.

Steering. Tie rods, axial joints, steering cylinders and seal kits, and the components behind multi-mode steering. Steering parts are among the most serial-break-sensitive on the machine, so confirm by serial number every time.

Hydraulics. Pumps, valves, cylinders and seal kits, hoses, and fittings across lift, extend, tilt, and steer circuits. A weeping cylinder often needs seals, not replacement, and a recurring hose failure points at routing or clamping.

Engine and electrical. Filters, belts, alternators, starters, sensors, switches, and gauges for the diesel engines, plus cab components, seats, and glass. Stocking a filter set per machine is the cheapest downtime insurance on a telehandler fleet.

Tires. Foam-filled and pneumatic options in the aggressive treads these machines run. Confirm size and configuration from the machine, and replace in matched sets on drive axles to protect the drivetrain.

Stability and safety systems. Components for the stability systems on larger models, plus alarms, beacons, mirrors, and the full decal set by model and serial range.

Should you use OEM or aftermarket SkyTrak parts?

The serial-break reality pushes hard toward OEM for anything drivetrain, steering, hydraulic, or structural: JLG’s documentation is the only source that tracks those revisions precisely, and a mis-fit axle joint costs far more than the part. Filters, belts, tires, seats, and commodity hardware are reasonable aftermarket territory when specifications match. The AirWorx parts team will tell you which is which for the specific component in front of you.

Local SkyTrak parts support in Indiana and Illinois

AirWorx carries SkyTrak in its rental fleet and sales inventory and services it in the field, so parts requests are backed by technicians who work on these machines weekly. Branches in Indianapolis, Fort Wayne, and Warsaw cover Indiana, and Flora covers southern Illinois, with parts transfer between branches and service trucks available around the clock. If a SkyTrak is down during committed work, telehandler rental coverage from the same branches bridges the repair.

How to order SkyTrak parts from AirWorx

Send the model, the complete serial number, the part number if known, the operating conditions around the symptom, and photos. Once the part is confirmed, ask what should be replaced alongside it, seals, hardware, filters, or the wear item behind the failure, and record the confirmed part number with the machine’s serial in your maintenance file so the next order starts from a known machine.
