Telehandler Hydraulic Pump Replacement Cost: JLG, Manitou, Cat, Genie

When a telehandler boom slows down mid-lift, the machine overheats during normal work cycles, or you start hearing a whine from the pump compartment, the hydraulic pump is the likely source. A pump replacement on a telehandler runs $2,000 to $9,500 all in, depending on pump type, machine size, and parts source. Here is what drives that range and what the job actually involves.

What the Hydraulic Pump Does on a Telehandler

Telehandlers use a variable-displacement piston pump as the main hydraulic source on most mid-range and full-size machines. This pump feeds all working functions from one output: boom lift, boom extend, tilt, fork leveling, auxiliary attachments, and on many models the four-wheel steering and differential lock circuits as well. A failing main pump affects all of these simultaneously, which is why the symptom pattern (everything slow at once, not one function) points upstream to the pump rather than to a specific valve or cylinder.

Smaller telehandlers and some compact models use a gear pump instead of a piston pump. Gear pumps are simpler and cheaper to replace, but less efficient at varying flow under different load conditions. The pump type determines the cost tier.

Telehandler Hydraulic Pump Replacement Cost

Pump Type	Parts Cost (Reman)	Parts Cost (OEM New)	Total with Labor
Gear pump (compact/light telehandlers)	$800-$1,800	$1,400-$2,800	$2,000-$5,000
Variable piston pump (mid-size, 6,000-9,000 lb capacity)	$2,200-$4,500	$4,000-$7,500	$3,800-$9,500
Variable piston pump (full-size, 10,000+ lb capacity)	$2,800-$5,500	$5,000-$9,000	$4,800-$10,500

Ranges assume shop rates of $95-$145/hr and 5-10 hours labor. Add $500-$1,500 for system flush and downstream contamination inspection if internal pump failure is confirmed.

Cost by Brand and Model

• JLG G6-42A / G9-43A / G10-55A: $2,500-$7,000 total. JLG telehandlers are the most common brand on North American sites, and the service market is well established. The G-series uses variable-displacement piston pumps from major suppliers with solid reman availability. JLG's mid-size machines (G6 and G9) sit toward the lower end of the piston pump range; the G10-55A runs higher due to larger pump displacement.
• Manitou MT625 / MT732 / MT1030: $2,800-$8,000 total. Manitou piston pump replacements run 10-20% above JLG comparables in North America due to longer parts lead times on European-spec components. The MT1030 and larger Manitou models use higher-displacement pumps that carry a parts premium. Confirm availability before scheduling the job.
• Caterpillar TH255 / TH414 / TH514: $3,500-$9,500 total. Cat telehandlers carry the Cat parts premium across all components. OEM Cat piston pumps are among the most expensive in the class, but the Cat dealer network makes reman units available with reasonable lead times. A reman pump from a Cat dealer is typically the right call over aftermarket on a Cat TH series machine.
• Genie GTH-636 / GTH-844 / GTH-1056: $2,500-$8,000 total. Genie telehandlers (part of Terex) use piston pump configurations with decent aftermarket reman supply. The GTH-844 is one of the most common rental telehandlers in North America, so parts availability is better than less common machines in this class. Gear pump compact Genie models run considerably less.

Signs Your Telehandler Hydraulic Pump Is Failing

• All boom functions are slow at the same time. If lift, extend, and tilt are all sluggish rather than one specific circuit, the main pump is losing output. A single slow function points to a valve, cylinder, or line issue downstream of the pump.
• High-pitched whine or moaning at the pump. Normal pump noise is a steady background hum. A whine that increases under load or when operating the boom at height is cavitation or internal wear. Cavitation (vapor bubbles collapsing inside the pump) sounds like fine gravel and causes pitting on the valve plate and piston bores.
• Hydraulic fluid overheating during normal work cycles. A pump that is losing volumetric efficiency works harder to maintain pressure, generating excess heat. If the machine is hitting its thermal warning sensor on jobs that did not cause overheating before, the pump is the first place to look after ruling out cooler blockage and low fluid level.
• Boom creep or drift under load. If the boom slowly descends on its own after you release the control, the first suspect is the counterbalance valve, not the pump. But if boom creep accompanies general hydraulic weakness across all functions, the pump output pressure has dropped below the point where the counterbalance valve can hold load.
• Error codes related to hydraulic pressure. Most modern JLG, Manitou, and Cat telehandlers (2015+) log fault codes for low hydraulic pressure at the main circuit. Pull the codes before ordering parts. A pump pressure code confirms the pump is below spec; a flow code versus a pressure code can help identify whether the issue is the pump, the relief valve, or a downstream restriction.

What to Check Before You Approve the Job

Three checks matter before you commit to a pump replacement.

First, check the hydraulic fluid and return filter. A clogged return filter starves the pump of return flow and causes cavitation. Check the filter indicator and pull the filter element before condemning the pump. Dirty or water-contaminated fluid is also a pump killer and means the system needs a flush regardless of whether the pump is replaced.

Second, have the shop test system relief pressure and pump output flow. Low system pressure with normal flow indicates a relief valve problem, not a pump. Low flow with normal pressure indicates the pump is worn. Getting the pump test data before ordering parts avoids replacing the wrong component.

Third, know your machine's value. A $4,500 pump replacement on a 2021 JLG G10-55A worth $85,000-$100,000 repaired is an easy yes. The same job on a 2010 Manitou MT732 at 10,000 hours, with a list of other deferred items, requires a clear-eyed look at repair-versus-replace. EquipBook's free valuation tool gives you a market value in under 60 seconds. Then use the repair cost estimator to price the pump job on your specific machine. Those two numbers make the decision straightforward.

OEM vs. Remanufactured vs. Aftermarket

• OEM new pump: Correct specs from day one, factory warranty, longest lead time and highest cost. Right for low-hour machines, machines still under warranty, or situations where machine availability during repair time justifies the premium.
• Remanufactured pump: The standard call for out-of-warranty machines. 30-50% below OEM, rebuilt to original pressure and flow tolerances, typically carries a 6-12 month warranty. Confirm the reman unit is rated to your exact pump part number, not just machine weight class. Variable-piston pumps vary meaningfully by displacement and pressure setting within the same model line.
• Aftermarket pump: Budget option, highest risk. Quality varies. On a telehandler where the pump feeds both the boom circuit (safety-critical at height) and the steering circuit, a pump that is close-but-wrong on pressure settings or seal materials is a liability. Use an aftermarket pump only from a supplier that cross-references your specific OEM part number and carries a warranty on the unit.
