Here at Fisher Power Supply we strive to provide our customers with an amazing engine that is better than the original. Our goal is to get the job done as quickly as possible; we understand that your time is valuable. Just because we are fast does not mean me skip important steps. 

First we disassemble the engine down to the block itself, from there each piece is inspected thoroughly for any cracks or defects. After inspection, all parts are cleaned. Each piece including the block, head(s), and cranks are replaced with new, remanufactured or machined within OE specifications. The injectors are tested and replaced. Once everything meet our standards during the  final inspection, the engine is assembled from the block up. 

Our technicians precision to detail ensure nothing gets overlooked. The engine is then tested and painted. We build our own custom crates for each engine. This ensures safety and security during the shipping process. Our crates are qualified for overseas freight as well. 

We GUARANTEE the satisfaction of our product that we deliver to you! 

We offer Short, Long and Extended Long Blocks for CAT. Our remanufactured long blocks meet or exceed OEM standards. 

A short block includes engine block, crankshaft, connecting rods, cylinder kits, and piston coolers.

A long block includes all of the above plus a cylinder head. An extended long block has everything a short and long black has in addition to a camshaft, front cover, and gear train. (Injectors, rocker arms, push rods, and bridges are additional for a tune-up. Extended long blocks will be timed. We use new or reman parts. Our reman parts are machined to OEM specifications.
