Here’s some pics of a Mopar crankshaft & harmonic balancer for a supercharged engine. In order to strengthen the balancer on the snout of the crankshaft for the extra pressure from driving the blower an extra keyway & woodruff key are needed. To do this we machine a slot in the snout of the crank [...]

Here’s some pics of some custom parts machining we did. We started with some solid rounds of plastic delrin material. We first cut the solid rounds into smaller pieces close to the dimensions of the final part. We then chucked each piece up in the lathe & machined them to match the dimensions on the [...]

Here's some pics of an old cast iron water pump that came in for repairing & rebuilding. It's off of an older forklift that is powered by a four cylinder Continental gasoline engine. The housing was corroded away internally along with the shaft & impeller. We had to get creative with the repair to the [...]

Here’s some pics of a custom water pump pulley we machined out of a solid round piece of aluminum. The larger pulley was shipped to us to use as a pattern for machining the smaller diameter pulley. We made the new water pump pulley as small as possible in order to clear the housing of [...]

Here’s some pics of a set of Caterpillar 16M Grader Axle lean arms 2641150 & 2641153 on our Rottler CNC machine. These lean arms came in on an axle assembly that was worn to the extreme. Both lean arms were completely worn on all surfaces & bores. To get the lean arms back to spec [...]

Here’s some before & after pics of an older cast iron water pump off of a Hercules model JXLD engine that was shipped to us for repairing & rebuilding. We completely disassembled the pump & performed all necessary machining to the cast iron housing, the shaft & seal areas. We also custom machine any of [...]

Here’s some pics of a Caterpillar Grader Axle on our Rottler Multipurpose CNC boring & milling machine. The surfaces on each side of the center support bore were badly worn so we welded them up & then machined them flat, square & back to the correct thickness spec. The surfaces that retain the lean arms [...]

Here are some before & after pics of an industrial 2-step flywheel we surfaced. The flywheel is off of a Kenworth semi truck with a manual transmission. We first machine the larger lower surface on our Winona Flywheel Grinding machine & measure how much material is removed. We then setup on the narrower upper surface [...]

Here's some pics of an aluminum Mendeola transmission housing that came in for machining. The housing is used as a jig during transmission servicing & the bore needed to be bored larger for its intended purpose. We set the housing up on our boring mill & machined the bore to the spec provided by our [...]

Here’s some pics of the cylinder heads on a Mitsubishi S6 inline six cylinder diesel engine in a Caterpillar DP40 forklift. We removed both cylinder heads due to blown head gaskets. We gave both heads a thorough cleaning, inspection for cracks & a complete valve job & surface. The heads were reinstalled with new head [...]
