This Lull 844-C42 was giving the customer a hard time with a brake pedal that would become stiff during operation. Our technician got on-site, inspected the pedal, and found the culprit — corrosion and rust taking their toll! 🦾

Time to get this machine back in fighting shape! 🔥 Our tech disconnected and capped off the hydraulic lines, removed the fittings and mounting hardware, and pulled out the old, corroded pedal. A brand-new pedal was installed and secured with fresh hardware. After reconnecting the hydraulic lines and topping off the hydraulic fluid, our technician tested the pedal to verify proper operation.

✅ Out with the old, corroded pedal!
✅ New pedal installed and secured
✅ Hydraulic lines reconnected and fluid topped off
✅ Function tested and verified

Our tech headed out to get a Komatsu FG25ST back up and running after it refused to start. After diving into the charging system, we discovered the battery was completely dead at just 3.5 volts—and the lift wasn’t charging at all!

We jumped the unit and ran it off a jump box to track down the problem, confirming the alternator wasn’t producing any voltage. With the issue identified, our tech got to work disconnecting the battery, removing the faulty alternator, and sourcing the parts needed to get this machine back in business.

Once back on-site, the new alternator was installed, all connections were secured, and the battery was reconnected. After firing up the unit, we tested the charging system and confirmed a healthy 14.5 volts! ⚡

✅ New alternator installed
✅ Charging system tested and verified
✅ Komatsu FG25ST ready to get back to work!

Our team headed out to service a Komatsu FG25ST after the customer reported a coolant leak and overheating issues. After diagnosing the problem, we found a failed water pump and a cracked radiator causing cooling system trouble.

Our tech got to work removing the failed water pump and installing a new pump with a fresh gasket. Next, we rigged and removed the rear counterweight to gain access to the radiator. After disconnecting the transmission lines, hoses, and heat shielding, we removed the damaged radiator and transferred the necessary fittings to the replacement.

With the new radiator installed, everything was reassembled, the cooling system was refilled and properly bled, and the lift was run to operating temperature to ensure everything was circulating correctly. After checking for leaks and cleaning up, the Komatsu FG25ST was ready to get back to work! 💪

When a customer called in with their CAT DP40 down in the middle of the yard, our tech headed out that same morning to get to the bottom of the issue!

Upon arrival, the unit would start but wouldn’t perform any functions, including travel. Releasing the parking brake also triggered the audible alarm, pointing our tech toward a potential issue with the Operator Presence System (OPS).

After inspecting the OPS fuses and finding no issues, our tech dug deeper into the wiring harness and discovered a wire that had come loose from its connector due to corrosion. The solution? Cut back the corroded wire, re-pin the connector, and get everything back where it belongs! 💪

✅ Problem identified. Repair completed. CAT DP40 back in service!

Another successful onsite repair helping our customer minimize downtime and get back to business. That’s how we get the job done at TCS Mobile Equipment Services! 🔥

Our TCS tech headed out to a customer location to diagnose a no-start issue on this 2015 Freightliner M2. After finding the batteries had dropped to just 3 volts, our tech attempted a jump-start but the truck still wouldn’t crank. Further diagnostics revealed the engine ECM had entered ROM Boot mode due to a corrupted calibration.

With customer approval, we removed the ECM and brought it to a local dealership for recalibration to the latest software. On the way back, we picked up new batteries to get everything taken care of in one trip!

Back onsite, our tech installed the new batteries, reinstalled the recalibrated ECM, and restored the saved ECM image from a previous repair. After clearing the related faults and verifying the system was communicating properly on the data link, the truck fired right up! ✅

💪 Repair verified, no active faults, and this Freightliner M2 is back in service!

Our team headed out to service a 2025 International LT625 after the check engine light came on. After connecting our diagnostic equipment and troubleshooting the active fault codes, our technician identified a failed Variable Geometry Turbocharger (VGT) actuator.

With customer approval, we sourced the necessary parts and returned the following day to get the truck back on track! 💪

Our technician drained the engine coolant, removed the failed actuator, cleaned the mounting surface, and inspected the sector gear to ensure smooth, unrestricted movement. A new VGT actuator and gaskets were installed, followed by the required installation procedure and calibration using our diagnostic tools.

After completing the repair, we refilled the cooling system, brought the engine up to operating temperature, topped off the coolant, cleared the fault codes, and verified the fault was no longer active.

✅ Repair complete. Diagnostics passed. Back in service!

At TCS Mobile Equipment Services, we’re committed to reliable repairs, quality workmanship, and keeping our customers’ equipment running strong with minimal downtime!

Our TCS tech headed out to the customer to tackle an overheating issue on a Yale GLP060 forklift. After diagnosing the unit, we found a failed water pump and a thermostat stuck closed, preventing the cooling system from operating properly.

Our tech got to work removing the necessary components to access the timing system, replacing the water pump, timing belt, and tensioners, and setting the engine timing to ensure everything was running as it should. We also replaced the thermostat, installed new hoses, and replaced the valve cover gasket. During the repair, we discovered both spark plugs were loose, allowing combustion gases to escape, so those were tightened down as well.

After reassembly, our tech refilled the cooling system, properly bled it, and ran the forklift to verify proper operation and confirm there were no leaks or further overheating issues. The unit was cleaned up, fluids were topped off, and the Yale GLP060 was officially released back to service! 💪

Our team headed out to a customer to get their Doosan GC55C-9 back in working order after a snapped tilt cylinder ear brought the machine to a halt.

Once onsite, our technician secured a safe work area and got straight to work removing the necessary panels and disconnecting the hydraulic lines. With the cylinder pins seized in place, some extra heat and persistence were needed to get them out. After removing the tilt cylinder and damaged ear, the area was thoroughly cleaned, and a new ear was installed.

Our technician then reinstalled the cylinder, reconnected the hydraulic lines, secured and torqued all hardware to spec, and greased the assembly. After testing the unit and verifying everything was operating properly, the work area was cleaned up and the machine was returned to the operator. ✅

Our tech headed out to the customer to get their Caterpillar NRR40 back up and running after the mast cable twisted and derailed from the roller, causing damage to the cable.

Safety first! The unit was properly set up and the platform was blocked before our tech got to work. Panels were removed to access the mast cable running across the platform and up over the mast pulley. The damaged cable was disconnected from both ends, routed out of the pulley, and replaced with a new length of cable.

Once the new cable was routed back through the mast and secured, the tensioning springs were reattached and adjusted to ensure the cable maintained the proper tension and stayed seated correctly on the pulley. One of the springs had also come loose, allowing the cable to lose tension, so that was secured as well to help prevent further damage.

After everything was back in place, the panels were reinstalled and the Caterpillar NRR40 was powered up and thoroughly tested. All functions were operating properly, and the unit was returned to service! 💪🔧

Another repair completed and another customer back to work with minimal downtime! 🚧⚙️

🌡️ Keeping the 2021 International HV607 Cool & Comfortable! ❄️🔧

Our customer called in with an A/C system that was no longer blowing cold air, and TCS got right on it!

After diagnosing the system, our tech found that the A/C compressor had failed internally, causing the clutch to seize and come apart. We also found excessive play in the belt tensioner. After getting customer approval, we returned to the site the following day and got to work.

The system was safely recovered, and our tech replaced the A/C compressor, HVAC filter, belt tensioner, and receiver dryer desiccant bag. The belt was reinstalled, the proper oil was added for the component replacements, and the A/C system was pulled into a vacuum before being charged back to specification.

After everything was back together, we thoroughly tested the system and verified proper operation. ❄️✅

Another 2021 International HV607 back in service and ready to keep working — with a properly functioning A/C system for the next job! 💪🔧
