Inspecting a Vintage Liebherr Dozer: Checks, Startup, and Potential Issues

Initial Inspection and Fluid Checks

• 🔍 Checking the oil on the Liebherr dozer, finding the level to be slightly above the line and good.
• 💧 The splitter box dipstick was located behind the fuel tube, and the oil level was confirmed to be good.
• 🌡️ Coolant levels were checked and found to be good, as was the air filter.
• ⚠️ A leaky cylinder was identified, with a leaking hose dripping hydraulic fluid onto the track, explaining low fluid levels.

Dozer Startup and Operation

• 🔑 The dozer was started with keys in the ignition, and the batteries held up despite the machine sitting for a while.
• ⚙️ Initial startup revealed the throttle wasn't immediately engaging, but it was resolved shortly after.
• 💨 The dozer's engine ran clean, though it rattled, consistent with its age.
• 💨 High speed was engaged, and the dozer was able to move, though it felt sluggish when pushing uphill.

Identified Issues and Potential Repairs

• 💧 A leaking hose on one of the cylinders was noted as a recurring issue that needs attention.
• ⚙️ Sprockets were found to be brand new, but the pins had not been changed.
• 🛠️ Potential repairs include repacking cylinders, replacing cutting edges, and investigating the sluggish pushing performance.
• 💨 The steering was noted to be better after some wiggling but still favored one direction.

Mechanical History and Parts

• 💰 The dozer was rebuilt on the farm for $3800 in parts.
• 🚪 The cab doors were removed and painted earlier in the year, and their location in the barn was confirmed.
• 🔩 Spare hydraulic hoses (one long, one short) are available in the barn for potential replacements.
• 💧 A large amount of hydraulic fluid was released when a hose was removed, but very little was spilled on the ground.

Future Plans and Considerations

• 🤝 The goal is to work out a deal for the dozer and potentially transport it to the steam show in Pennsylvania.
• 🔋 Batteries were removed for storage, as the dozer won't be started again until warmer weather.
• ⚠️ A fire extinguisher was recommended to be kept nearby due to potential heat issues.
