Here’s some pics of a couple of Mitsubishi diesel cylinder heads off of a Caterpillar DP40 forklift we're rebuilding. The head gaskets were blown so we gave the heads a complete valve job & surface. The deck surfaces of both heads have hardened pre-chamber inserts which require special attention to detail for the surfacing process. [...]

Here’s some pics of a 5.9 liter B-series Cummins head out of a Dodge truck. The engine overheated which caused the head gasket to embed itself into the deck of the head. After magnafluxing the head & no cracks were detected we mounted it on our Rottler CNC machine to mill the surface. The deck [...]

This is a couple of aluminum 5.3 Chevy LS cylinder heads that came in for inspection & surfacing. We hot tanked both heads to remove the oil & dirt from them so we could dye check them for cracks. After no visual cracks were detected we pressure tested the heads to ensure they have no [...]

This is a Yamaha cylinder head off of an Arctic Wildcat XX that came in needing some machining due to being overheated. The surface, or deck, of the head was warped & twisted. We surfaced the deck flat & smooth for a good seal to the new head gasket. The engine in the Wildcat XX's [...]

Here's a couple pics of a driveshaft we made for an ice plant. The original shaft was broken so we were given a drawing with dimensions & specs to machine to. This driveshaft is what we ended up with after machining a solid steel bar stock to the specifications of the drawing. Motor Mission Machine [...]

Here’s some pics of a cylinder head & cylinder block for a Polaris RZR XP1000 UTV side-by-side. We performed a three angle valve job & surface on the cylinder head to bring it back up to snuff. The cylinders were good enough to get by with a quick brush up with our diamond stones in [...]

Here's some pics of an engine block while we were honing the cylinders to size. We have a torque plate installed & torqued to the deck to simulate the cylinder head being installed. The torque plate distorts the cylinders as the cylinder heads would when they are installed. This allows us to hone the cylinders [...]

Here’s some engine rebuild parts we ordered in for an engine build. The parts are for a 2019 Kawasaki 450 dirt bike that suffered internal damage due to a loss of oil. The cases & cylinder head luckily lived with no damage but the crankshaft, connecting rod & cylinder need to be replaced. The piston [...]

Here's some custom machined tubular bushings we made for one of our customers. They call these dog bone bushings which are used on the Caterpillar haul trucks. We make them out of a high grade steel material which yields a higher hardness than typical off the shelf steel material does. This is a batch of [...]

Here's a couple of trailer hubs that came in with the bores worn & damaged where the races are supposed to press in place. We machined the bores true, round & on center. We then machined some sleeves which we pressed into the reconditioned bores. After the sleeves were pressed in place we machined the [...]
