ESCO 10839 Yellow Jackit Combi Bead Breaker Kit

The ESCO 10101 "Combi" Bead Breaker in this kit is designed for 1-piece, 2-piece, and 3-piece truck tires and rims, including many agricultural and newly styled wheels. It is the most widely used bead breaker for agricultural wheel applications. It is not compatible with 5-piece Earthmover giant wheel/rims - for those applications, ESCO's Model 10100 or Model 10105 is required. The tool clamps hydraulically onto the wheel assembly, making rim type compatibility a key factor before purchase.

The ESCO 10101 Combi Bead Breaker generates 13.8 tons of hydraulic force with a maximum stroke of 3.75 inches (95 mm) at a maximum operating pressure of 10,000 PSI. This level of force is sufficient to break even heavily corroded or rust-bonded beads on heavy truck and agricultural tires in seconds, significantly reducing operator effort compared to manual or mechanical bead breaking methods.

The primary difference is the pump included with each kit. The 10839 kit includes the ESCO 10877 pump with a rugged metal reservoir, while the economy 10820 kit uses the 10875 pump with a plastic reservoir. Both pumps are rated to 10,000 PSI and share the same core features, but the metal reservoir is more durable under heavy field and shop use. Both kits include the same hose assembly (Model 10604) and air reducer (Model 10601K), but the 10820 uses the 10895 bead breaker tool rather than the 10101.

The ESCO 10877 Yellow Jackit pump requires 5-10 CFM of air flow at 100 PSI inlet pressure for proper operation. The pump operates on a 100:1 hydraulic ratio - 100 PSI of inlet air pressure produces 10,000 PSI of hydraulic output pressure. The included 10601K air reducer regulates inlet air pressure to protect the pump from over-supply. A standard shop compressor capable of sustaining 100 PSI at 5-10 CFM will operate this kit effectively.

ESCO recommends using AW-32 weight hydraulic jack oil in the 10877 pump. The pump ships with some oil installed but may need topping off before first use - always check the oil level before operating. Do not use automotive engine oil, brake fluid, or other non-compatible fluids, as they can damage internal seals and void the warranty. The metal reservoir holds 5 quarts of hydraulic fluid. Use the vented oil filler plug when refilling and wipe the pump clean before storage.

Yes - the 10839 kit includes the four components needed for a complete bead breaking setup: the ESCO 10101 Combi Bead Breaker Tool, the 10877 Yellow Jackit 5 Qt Metal Pump, the 10604 8-foot hose assembly with coupler, and the 10601K 6-inch whip-hose air reducer. You will need to supply a compressed air source capable of 5-10 CFM at 100 PSI and AW-32 hydraulic oil if the pump reservoir is not pre-filled. No additional tools or adapters are required for standard 1-piece, 2-piece, and 3-piece rim applications.

The ESCO 10101 Combi Bead Breaker Tool carries a 3-year warranty against defects in materials and workmanship, valid for the first using purchaser. To qualify for the full 3-year term, the warranty card must be on file or the product must be registered online at esco.net/warranty. The 10877 Yellow Jackit pump and accessory components carry a 1-year warranty from the date of delivery. Warranty is non-transferable and applies only to products purchased through authorized ESCO dealers.

The ESCO 10101 Combi Bead Breaker is designed for field serviceability with replaceable wear parts including the clamping jaw, pushing foot, and teeth. Individual replacement components are available separately from ESCO, so technicians can swap worn parts without replacing the entire tool. The redesigned sequence valve screw also improves long-term serviceability compared to earlier versions, which were prone to damage during normal use and difficult to adjust or replace.

The kit includes the ESCO 10604 8-foot hose assembly with swivel fittings and a hose coupler. The hose is reinforced with two layers of braided steel and rated to 10,000 PSI, matching the maximum operating pressure of the pump and bead breaker. The 3/8 in x 3/8 in male swivel ends connect easily to the pump and tool without tools. An additional 6-inch whip-hose air reducer (Model 10601K) is also included to regulate the air inlet to the pump.

No - the ESCO 10101 "Combi" Bead Breaker is not compatible with 5-piece Earthmover giant wheel/rims. For those applications, ESCO offers the Model 10100 Giant Tire/Earthmover Bead Breaker (also available in kit form as the ESCO 10838) or the Model 10105. The 10100 is specifically engineered for 5-piece rims ranging from 25 to 51 inches and features pry bar/bead loosening pockets designed for that rim type. For mixed shops servicing both standard truck and 5-piece OTR applications, a second bead breaker tool would be required.

Key maintenance steps for the 10877 pump include: checking and maintaining the AW-32 hydraulic oil level before each use, inspecting hoses and connections daily for leaks and tightening as needed, using non-hardening pipe thread compound on any serviced connections, lubricating pivot points and hinges with light machine oil, depressurizing the system before disconnecting hoses, and storing the pump in a clean, dry environment away from temperature extremes. Never operate the pump with the release valve closed and disconnected from the tool - doing so pressurizes the hose and creates a burst hazard.
