Equipment we service

The machines we know, and the problems we fix.

These are the heavy equipment brands we service and the real problems that come up on each one, including cab A/C and heat. The fix starts the same way every time: we find the cause, give you the quote, get the parts, and fix the problem. We come to you and get it back to work ASAP.

Don't see your brand or your problem? It's still something we handle. Request service and tell us what's going on.

John Deere

John DeereExcavators · 333G / 331G track loaders & skid steers · dozers · tractors

Limp mode / DEF fault

Tier 4 machines like the 333G drop into limp mode over a DEF or sensor fault and lock you out. We read the codes, run the regen, and clear the derate on-site.

Cab A/C blows warm or quits in the heat

Common on the cab tractors and excavators: a refrigerant leak, a packed condenser, or a worn compressor. We find the leak, recharge it, and fix the cause on-site.

Final drive whine or a track that won't pull

Common on the track loaders. We check the final drive and undercarriage where it sits.

Caterpillar

Caterpillar (CAT)320 / 330 excavators · D-series dozers · 950 wheel loaders · skid steers

The house keeps swinging on a slope

That's the swing brake or the swing motor, not the bearing. We test both and fix the one that's worn.

Wheel loader slips or overheats when it gets hot

On the 950 that's low charge pressure or a tired torque converter. We test the pressures and tell you which it is.

Cab A/C blows warm

On the excavators, dozers, and loaders it's usually a refrigerant leak, a packed condenser, or a tired compressor, not the whole system. We find the leak, then evacuate and recharge it on-site.

Komatsu

KomatsuPC excavators · dozers

Random fault codes and electrical gremlins

These machines are heavily electronic, and the cause is a chafed harness, a corroded connector, or a bad ground, not the control unit. We chase the wire.

Boom or bucket settles on its own (cylinder drift)

A worn control-valve spool or cylinder seals. We confirm which and rebuild it.

Final drive and travel-motor wear

A whine behind the sprocket or a slow track. Checked and rebuilt on-site.

Hitachi

HitachiExcavators (their specialty) · wheel loaders

Weak or slow hydraulics, worse under load

The main pump, a regulator, or contaminated oil. We test flow and pressure first, so you're not buying a pump you didn't need.

Swing drift and final-drive wear

The high-hour excavator problems. Diagnosed and fixed on-site.

Slow to start or a no-start

A relay, a ground, or a connector. We trace it instead of throwing parts at it.

Volvo

VolvoExcavators · wheel loaders · articulated dump trucks

Cylinder drift on older EC excavators

The boom or bucket creeps down. We pin down whether it's the spool or the cylinder.

DEF / emissions derate on Tier 4 machines

The machine drops into limp mode and won't reset. We clear it on-site.

Articulated truck driveline and hitch wear

Play and noise in the center hitch and driveline. We rebuild the worn joints.

Case

CaseBackhoes · skid steers · excavators

Weak loader lift or a slow hoe

Backhoe hydraulics or the transmission. We test before we touch a part.

Skid steer cuts out or locks the controls in the seat

The seat switch or the interlock connector. We track it down fast.

Pin and bushing slop in the loader and hoe

Worn pins make everything sloppy. We replace them on-site so it tightens back up.

Link-Belt

Link-BeltExcavators · cranes

Weak or slow excavator hydraulics

The main pump, a relief setting, or contaminated oil. We test flow and pressure first.

Final drive and travel-motor wear

A whine behind the sprocket or a track that won't pull. Rebuilt on-site.

Crane load systems, hydraulics, and outriggers

Specialized work a lot of shops won't touch. We do.

Bobcat

BobcatSkid steers · compact track loaders · mini excavators

Drive chains loose and rattling

On chain-drive skid steers there's no way to adjust them, so loose means worn. We check the chaincase too; milky oil means water got in.

Cab A/C blows warm

The enclosed-cab machines lose refrigerant at a vibrated-loose fitting, or the condenser packs with debris. We find the leak, recharge it, and get the cab cold again on-site.

Overheating and seat / lap-bar shutdowns

A debris-packed top radiator, or an interlock switch cutting the machine out. We find which and fix it.

Kubota

KubotaCompact excavators · SVL track loaders · tractors

Small diesel running hot

A packed cooler or a worn water pump. We catch it before it cooks a head gasket.

SVL regen won't complete / DPF fault

The machine needs the right conditions to regen, and a sensor or wire blocks it. We force the regen and find the cause.

Cab A/C won't keep up

On the cab tractors and SVL loaders the small system loses charge or the condenser packs with debris. We find the leak, recharge it, and clean the condenser on-site.

JCB

JCBBackhoes · telehandlers · excavators

Backhoe hydraulics and transmission

Weak lift, slow hoe, or rough shifting. Diagnosed on-site.

Telehandler boom and leveling faults

Sensors and hydraulics on the boom and the frame-level system. We test and fix the fault.

Electrical and emissions faults on newer machines

Fault codes, sensors, and DEF / limp mode. Cleared on-site.

JLG

JLGBoom lifts · scissor lifts · telehandlers

Lift won't raise or won't level

A tilt or level sensor, a hydraulic valve, or a ground/connector fault, not the whole machine. We pull the fault code and find it.

Drift in the boom or platform, and hydraulic leaks

Worn cylinder seals or a leaking valve. Repacked and sealed on-site.

No-start or dead controls

A battery, a ground, or an interlock, not the control board. We trace it.

ASV

ASVPosi-Track compact track loaders · skid steers

Undercarriage wear

The Posi-Track undercarriage runs bogie wheels and bearings that wear and seize. We check the whole undercarriage on-site.

Hydrostat power loss when hot

A worn pump or a plugged cooler. We test it under load.

Drive motor and sprocket wear

Noise and slow drive on one side. We check the drive system and replace what's worn.

BOMAG

BOMAGRollers & compactors · milling machines

Vibration won't work

The exciter / eccentric system or its hydraulics. We diagnose it and fix the cause.

Roller hydraulics, pump cavitation, and drive faults

Weak drive or a noisy pump. Tested and repaired on-site.

Engine and emissions faults on the newer rollers

DEF and regen faults that derate the machine. Cleared on-site.

Wirtgen

WirtgenCold milling machines · recyclers

Conveyor and cutter-drum hydraulics

Specialized road gear that's expensive to truck to a dealer. On-site work saves real downtime.

Cutter-drum picks and the water-spray system

Worn picks and a clogged spray system. We service and replace on-site.

Engine, drive, and grade-control faults

The machine controls and the grade system. We diagnose it where it sits.

Tigercat

TigercatFeller bunchers · skidders · mulchers

Heavy-cycle hydraulics and overheating

These work hard in the woods, and the coolers pack with debris. We come to the wood lot and clean and fix it.

Undercarriage wear and final drives

On the tracked machines. Checked and rebuilt on-site.

Cab A/C buried in debris, blowing warm

Bark and sawdust pack the condenser and the system loses its charge, so the cab cooks. We clean it out, find the leak, and recharge it at the wood lot.

Morbark

MorbarkBrush chippers · horizontal grinders · stump grinders

Wear parts and driveline

Knives, hammers, screens, and the clutch / driveline. We service and replace on-site.

Feed-system hydraulics

Weak or stalling feed rollers under load. Tested and repaired in the field.

Overheating under heavy load

Packed coolers and worn pumps. We clean it out and fix the cause.
