I'm considering buying a John Deere 770 grader with an unknown year and 11,000 hours showing on the meter. The engine reportedly had a connecting rod failure, but it starts well when hot or cold, with slight blow-by and no unusual noises. Could the hour meter be accurate, and what should I check...

Has anyone operated a scraper equipped with a rolling push block? I saw a new design at CONEXPO and would love to hear how smoothly it works on-site, especially during pushing and loading operations.

I recently bought a used paver and need to release the hydraulic pressure on the conveyor drag chain tensioner. The system pressurizes when the engine starts. Does anyone know the correct procedure for safely releasing the pressure?

My 1976 Terex S7 scraper with a Detroit 471 engine overheated recently. Now the coolant keeps disappearing, and the engine oil has white slime. I also drained 2-3 litres of coolant from the oil pan. Could a head gasket, a cracked head, or another engine problem be causing this?

My Case 580C has a new battery and starter but won’t crank. I hear one click when turning the key, then nothing until I disconnect and reconnect the battery. Could a starter solenoid, ignition switch, or safety switch be causing this Case 580C no-start issue?

My Komatsu D37EX-21A starts and the blade works, but the dozer has no travel at all. It shows a DAFRKR E03 communication error, while the HST controller, instrument cluster, wiring harness, powers, grounds, and 120-ohm resistors have been checked or replaced. What else should I check for this...

I need to replace the brake band on a John Deere 400G. Can it be accessed through the topside cover, or does the final drive need to be removed?

I'm tired of replacing the rubber straps on my CAT 140H steps. Has anyone tried using CAT 140G cable steps on a 140H, and do they fit properly?

Our Volvo A35D loses rear brake pressure after a few hours of work. Revving the engine brings the pressure back up, while the front brakes hold pressure fine. What should I check first?

My Cat 950G wheel loader has weak power when lifting a loaded bucket. The HEUI pump was replaced, and the injectors are being checked. Could the torque converter or magnetic screen also be causing the problem?

I'd check the brake linkage and adjustment first, then look at the hydraulic system if the pedal travel is still too long.

They've helped reduce downtime and keep our equipment working more efficiently.

The left screed heater and extension heater on my Weiler P385B are not working. Does anyone know what voltage the generator supplies to the heaters? Any help would be appreciated.

Check turbo boost pressure too.

I'm looking into lift options for servicing large wheel loaders and wanted to hear what others are using. What type of lift do you find works best for handling the weight, clearance, and maintenance needs of larger loaders? Have you found any specific brands or lift systems that offer the best...
