In response to Nige, James Sorochan expressed his gratitude and mentioned plans to contact them for more information about the unit. Specifically, the engine serial number for a 3306 DI engine should either be a 7JB or a 13Z. Bob also added some insights to the conversation.
I have obtained the serial numbers for the two units up for sale: 9YC00844 and 9YC00736. After consulting with a mechanic, they mentioned that both units are in good condition but one of them may have a slipping transmission between 2nd and 3rd gear. To identify which unit has this issue, the mechanic suggested checking the transmission strainer for any contaminants. I will be speaking to the auction representative to arrange a test drive of the units before the late November auction. Any assistance or advice on this matter would be highly appreciated. Thank you to everyone who has provided their support thus far.

Interestingly enough, a prominent local highway contractor relies heavily on their D25D for various highway projects. Despite having the resources to choose any equipment they desire, they continue to use the reliable machine. Finding a well-maintained D25D at an affordable price may be a challenge, but good luck in your search!
Back in the early 1980s, a small coal mine where I was employed made a groundbreaking purchase - one of the earliest units of its kind in the state. At that time, it was a basic DJB model, not a Cat. This innovative machine revolutionized our mining operations, allowing us to work year-round. Despite being able to haul the same amount of material as a highway truck, its all-wheel drive, large tires, and power shift transmission ensured seamless operation on steep slopes without breaking down. While the maintenance learning curve was steep, the machine's impressive performance made it worthwhile. It was the brainchild of an outsider to the Cat system who recognized the design's potential and bravely brought it to life. Eventually, Cat acquired the company.
According to John C., the success of the Cat ADT machines was made possible by an outside visionary who recognized their potential and took a chance on the design. Eventually, Cat acquired the company behind the innovative product line. This strategic partnership allowed DJB to supply components for ADTs equipped with 100% Cat power trains, which became their top selling point. As DJB's success grew, Cat took notice and acquired the rights to their product line. Today, all Cat ADT machines are still produced at the original site where DJB first started in the 1970s. Similar success stories can be found with Elphinstone and Tiger, whose products designed alongside Cat equipment also became part of the Cat family.

We currently offer two durable D25d trucks, which are ideal for navigating through the woods due to their short wheel bases. These reliable units, as noted by John, share a power train with the popular 966d wheel loader, ensuring easy access to parts and maintenance. Keep a close eye on a few key areas, but overall, these trucks are known for their toughness and dependability.
Hey there JPV! I'm curious, what are the key elements you recommend monitoring closely, and how can we ensure they are on track? Appreciate your insights.

When inspecting a machine, it is important to pay attention to the typical signs of wear and tear. One of the most common issues we address is with the brakes. The brakes are operated by air over hydraulic actuators, with one in the front and one in the rear. Regularly checking the reservoirs is crucial, as a loss of fluid can go unnoticed for a while. While the brakes are designed to adjust automatically, manual adjustment of the backing plates may be necessary at times. Failure to do so can lead to excessive wear on the brake shoes. One challenging aspect of brake maintenance is removing and reinstalling the hub and wheel.
Operators should be mindful of a few key points. Always ensure the parking brake is fully released before driving off, and run with the dump lever in the float position. Leaving the parking brake engaged while driving can cause damage. The shaft brake at the back of the transmission is strong when the truck is stationary, but not when in motion. Replacing it can be costly and complicated. Running in the float position also helps protect the dump valve from potential leaks caused by oil shockwaves.
Lastly, maintaining the torque converter locked up as much as possible by running at the appropriate RPM can prevent overheating. Downshifting before the transmission gets hot from the torque converter slipping is recommended, especially when climbing hills. Keeping an eye on the dashboard indicator for the locked and unlocked position of the torque converter is crucial. By following these guidelines, potential issues can be minimized.
I traveled to the west of Edmonton to inspect the rock trucks. Despite being promised a meeting at the auction site, no one appeared. I thoroughly examined both units, started them up, and tested their movements. It was evident that one of the trucks was in better condition than the other. I also observed that one of the rear wheel brakes was leaking oil. Check out the pictures below for a closer look.

Check out these additional images, focusing on the weld in the third picture and the leak on the back wheel track line. Any thoughts on this issue? Perhaps you're familiar with JPV.

The substance that appears to be leaking is most likely brake fluid, which is fortunate as it is much simpler to replace the wheel cylinder than the wheel seal. A quick sniff or taste test can confirm this. The wheel cylinder can be easily screwed into the axle housing, with rear axle cylinders being more accessible than front axle ones. I even created a custom socket to help remove the front ones. It's worth noting that they are typically secured with Loctite, so some heat may be needed if they prove difficult to remove.
It's important to keep an eye on the welds, although we haven't experienced any cracking issues with ours so far (fingers crossed!). From the pictures you've shared, everything looks good. If they were closer, my boss would likely be interested in bidding for them! These items are not commonly available for sale in our area, with one of ours actually coming from Texas.
I believe you are correct regarding the brake fluid. While conducting a test on the torque converter by keeping the brake on for a few minutes to monitor heat levels, the machine's water temperature began to rise. I stopped the test and discovered that the radiator was low on antifreeze. The equipment was obtained from an estate auction and appears to have been idle for an extended period.
