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 [...]

Here's some pics of a 2007 Kawasaki KX450F aluminum cylinder head we rebuilt. The head had some bent valves which cracked the valve guides. We removed the cracked & broken valve guides & installed new valve guides. We then did a three angle valve job on the valve seats. The deck was then surfaced flat [...]

Here's some pics of some small bores of a Caterpillar Grader Axle Spindle Housing after we welded them up with our line bore welder. We first machine the worn bores oversize to clean & true them up as well as make room for the build-up of weld material. The next step after welding the bores [...]
