Telehandler Hydraulic Repair Cost: Full System Guide (2026)

Real cost ranges for every hydraulic repair on a telehandler: boom cylinders, carriage tilt, outriggers, steering, and pump. Covers JLG, Manitou, Cat, and Genie. Know the number before you call the shop.

A telehandler's hydraulic system handles boom extension, boom lift, carriage tilt, fork positioning, outrigger deployment, and steering. When any part of that system fails, the whole machine slows down or stops. Here is what each repair actually costs in 2026, by system and machine size.

Boom Cylinder Repair: Lift and Extension

The boom cylinder takes the most abuse on a telehandler. It lifts and extends under load, thousands of cycles a day on active job sites. Cylinder seal failure is the most common hydraulic problem on telehandlers with 3,000 or more hours.

Symptoms: oil weeping from the cylinder rod, slow or uneven boom extension, boom drift under load (the load slowly drops without touching the controls).

Repair	Typical Cost Range
Boom lift cylinder seal replacement	$600-$2,200
Boom extension cylinder seal replacement	$700-$2,500
Cylinder rod replacement (bent or scored)	$900-$3,500
Full cylinder rebuild (rod, seals, guide bushing)	$1,200-$4,000

Cylinder work on a JLG G-series or Genie GTH typically falls toward the middle of these ranges. Cat TH series cylinders carry the Cat parts premium and sit at the top. Manitou cylinders have reasonable aftermarket supply and often come in under JLG OEM pricing.

A scored rod is the most expensive outcome. If the rod wears through the chrome surface, the seals fail repeatedly until the rod is replaced or re-chromed. Catch cylinder weeps early. A small seal job at 3,200 hours beats a rod replacement at 4,500.

Carriage Tilt Cylinder

The carriage tilt cylinder levels the forks as the boom raises. On telescoping handlers used in rough terrain or farm applications, this cylinder gets more use than on a job site telehandler held at one height for most of its work.

Repair	Typical Cost Range
Carriage tilt cylinder seal replacement	$400-$1,400
Tilt cylinder full rebuild	$700-$2,000
Tilt cylinder replacement (OEM new)	$1,200-$3,200

On farm and ag telehandlers (Manitou MLT series, JCB Loadall), the carriage tilt cylinder sees heavy use and is worth inspecting at every 500-hour service interval. The seal kits are inexpensive; catching a weep before the rod scores keeps the job under $800 most of the time.

Outrigger Cylinders

Telehandlers rated for lift heights above 40 feet use outrigger cylinders to stabilize the machine. Seal failure on outriggers is a safety issue: a leaking outrigger cylinder can collapse under load during a high reach lift.

Repair	Typical Cost Range
Outrigger cylinder seal replacement (per cylinder)	$350-$1,100
Outrigger cylinder full rebuild (per cylinder)	$600-$1,800

Most machines with outriggers have four. A full set of outrigger seal replacements runs $1,400-$4,400 parts and labor. If you see drift in one outrigger during a static load hold test, inspect all four and rebuild them as a set.

Steering Cylinder

Four-wheel steer telehandlers use hydraulic steering cylinders on the rear axle and sometimes the front. A steer cylinder leak is usually visible as oil on the inside of the wheel or on the axle housing.

Repair	Typical Cost Range
Steering cylinder seal replacement (per axle)	$300-$950
Steering cylinder full replacement	$700-$2,100

Hydraulic Pump Replacement

The hydraulic pump powers all of the circuits above. When the pump fails, nothing works. Pump replacement on a telehandler runs $2,000 to $9,500 all in, depending on pump type and machine size. The detailed telehandler pump replacement cost guide breaks this down by brand and pump type. The short version:

Gear pump (compact telehandlers): $2,000-$5,000
Piston pump (mid and full-size): $4,500-$9,500
JLG G9-43A / G10-55A: $2,500-$7,000
Cat TH414 / TH514: $3,500-$9,500
Genie GTH-844 / GTH-1056: $2,500-$8,000
Manitou MRT 2150: $3,000-$8,500

Hydraulic Fluid and Filter Service

Contaminated fluid is the most common cause of premature hydraulic failure on telehandlers. Most manufacturers call for a fluid and filter change at 1,000-2,000 hours. A full hydraulic fluid flush and filter service runs $250-$700 depending on machine size and fluid capacity.

If you are seeing cloudy or foamy fluid, or the fluid smells burnt, do not wait for the scheduled interval. Those are signs of internal contamination or overheating that will damage cylinders and the pump if they keep running in dirty fluid.

When to Repair vs. Replace

A 5-year-old JLG G10-55A in good condition is worth $65,000-$90,000 today. A $2,200 boom cylinder seal job is an easy yes. A $7,500 pump replacement is around 8-11% of machine value on that machine. Still worth doing if the rest of the machine is in good shape.

The harder call comes when the hydraulic repair arrives alongside high-hour engine concerns or significant structural wear. Before you authorize a repair bill over 20% of machine value, know what your specific machine is worth right now.
