CAT 3054 Engines For Sale

Caterpillar 3054 Engine

The CAT 3054 engine is a powerful piece of machinery capable of producing between 70 – 130 hp. The 3054 is a highly versatile engine with a fairly simple design. It boasts low maintenance costs and can be fitted with a turbocharger when needed. This engine is commonly seen in small skid steers, but it's also utilized in agricultural equipment, chippers, grinders, compactors, rollers, compressors, cranes crushers, forklifts, harvesters, hydraulic pumps, irrigation equipment, loaders, mining, earth movers, sprayers, trenchers, and even landscaping equipment.

The Cat 3054 engine’s design was influenced by Perkins. From the mid 1970s until finally being purchased by Caterpillar (for the sum of $1.325 billion), the UK-based Perkins previously supplied the 3054 to CAT. Consequently, after acquiring Perkins in 1998, Caterpillar became the world’s largest diesel engine manufacturing company.

Caterpillar 3054 Engine Replacement Options

There are a host of issues that can harm your 3054, but not all of them mean the engine is dead in the water. While certain failures often do determine that the engine is beyond saving, at times some engines juse need a few replacement parts or a simple refresh. We at Big Bear Engine Company understand that factors such as time, money, and availability factor into your decision when it comes to buying a new engine, and that’s exactly why we provide remanufactured long block options. They represent an affordable solution with quick turnaround.

The Big Bear Remanufacturing Process

A remanufactured Caterpillar 3054 long block is a wise choice for anyone who has had the misfortune of suffering a severe breakdown, especially if there are reusable external parts on the old engine. Perhaps more importantly, our reman long blocks are a great option if you’re trying to work on a budget.

Our team of dedicated machinists and engine builders will execute a full core tear down, cleaning, inspection, and machining of your 3054 before it leaves our facility. The ability to remanufacture the engine completely in-house ensures the highest quality possible, each and every time. We follow the same process with every engine we build.

Our method of remanufacturing Cat 3054 engines means they're constructed using both reman and new parts. We do not recondition or refurbish old engine parts. Instead, we completely rebuild your old Caterpillar 3045 engine back to OEM specs.

Thorough Cleaning

A comprehensive cleaning is vital in the engine rebuilding process. Our goal is to spot any impurities or potential structural flaws that could contribute to component failure or engine failure. This is performed by stripping the 3054 and then putting the block, head, rods, crankshaft, and camshaft through a chemical jet wash or hot tank.


The Cat 3054 crankshaft is precision machined to exact tolerances, polished, and then magnafluxed. The crankshaft then undergoes a thorough inspection, performed by our quality control department, to ensure quality is maintained.

Cylinder Head

It is imperative that the final product is compatible with modern gasket materials. For this reason, the head is resurfaced to both guarantee a proper sealing surface with the block and a finish that works harmoniously with modern head gasket materials. Valve height is mic’d and every head is vacuum-tested to assure correct valve seating.


The block is carefully inspected using magnetic particle to pinpoint any cracks or imperfections. The cylinders are then bored, honed, and inspected for precise tolerances. Torque plate honing is performed on some engines to eliminate the chance of cylinder distortion occurring after the head is installed and torqued to the block. This process serves to eliminate a major cause of engine blow-by. All block surfaces are machined and then inspected to ensure proper finish.


The camshaft is examined and precisely machined to provide correct lift. Lobes are measured with a micrometer to make certain all OEM tolerances are met.

Connecting Rods

Each connecting rod is thoroughly cleaned, machined to OEM specifications, and then honed to the standard diameter of original equipment for even distribution of stress across the bearings. New bushings are also fitted and machined in all bushed rods. Every connecting rod is carefully inspected for any bend and/or twist.

New Parts

All Cat 3054 long blocks receive a set of new parts as standard equipment. These include: pistons and rings, bearings, gaskets and seals, and liners. New parts assure dependable performance and reliability throughout the life of your engine. All new parts are a combination of OEM and aftermarket components, when available.

Remanufactured Engines Standards

For the best possible result, our remanufacturing process aims to make the engine as close to new as possible. All wearable parts are automatically replaced, and all Caterpillar 3054 core material is thoroughly inspected and examined against original equipment specifications for correct dimensional tolerances. Replacement parts are either new or requalified. We also mirror the same production process(es) as the original equipment if or when new parts are required. Testing on all of our Cat 3054 engines is then performed according to manufacturer specifications and original production standards.
