Here's some before & after pics of a set of inline six cylinder John Deere 744E diesel engine connecting rods. The big ends of the rods were out-of-round & required resizing, or reconditioning. The small ends are tapered with bronze tapered wrist pin bushings & they were scored & worn. We pressed the old bushings [...]
Here’s some before & after pics of a pair of Caterpillar D11R Dozer hydraulic cylinder blade lift yokes we repaired. We turned the inner & outer shafts of the 4390693 yokes on our Monarch lathe. We then welded the shafts back up & then turned them back down to the OE specs. Both yokes are [...]
Here’s some before & after pics of an Arctic Cat Wildcat XX 1000 side-by-side UTV cylinder head that we surfaced. The cylinder head came in with some warpage on the deck surface from overheating due to a water pump failure. We leveled & secured the head to our Rottler CNC boring & milling machine & [...]
Here’s some pics of a bracket, or blade hanger, on our CNC boring & milling machine. This piece attaches to the underside of the drawbar on a 16G Caterpillar grader. The blade, or moldboard, hangs from & slides side-to-side on the bottom of this bracket. The bores where the blade hanger pins up to the [...]
Here’s some pics of a compact diesel engine out of a Caterpillar mini excavator that came in for cleaning, inspecting & machine work. The engine is labeled under the Mitsubishi brand but it is ultimately manufactured by Perkins. It is a three cylinder model S3Q2. The block was machined for cylinder sleeves which were bored [...]
Here’s some pics of an International, or Navistar, Maxxforce 13 diesel engine cylinder head that came in for repairing & rebuilding. The head is off of a piece of Caterpillar equipment. At least two of the cylinders are damaged with burnt & broken valves. There are also numerous cracks in the deck of the head [...]
Here’s some pics of an International, or Navistar, Maxxforce diesel cylinder head we did a valve job & surface rebuild to. The original head had multiple cracks in most of the cylinders. We ended up exchanging the head with this one. This head has some dings on the surface which are due to some valves [...]
Here's some pics of a 3406 Caterpillar cylinder head we rebuilt. The 3406 is one of the most popular diesel engines we've done machine work to over the years. The cylinder head was disassembled, cleaned, magnafluxed for cracks, fully inspected & pressure tested before any machine work was done. After everything checked out okay the [...]
Here’s some pics of an industrial size two step flywheel we surfaced. We didn't get any pics of it beforehand but someone tried machining it on a lathe which left not only an extremely rough finish but also some deep grooves which we had to grind out. The flywheel bolts to the back of the [...]
Here’s some pics of a set of 4.0 Ford V6 aluminum cylinder heads we had in for machining. The surfaces of both heads were warped which called for milling the decks, or surfaces, for mating to some new head gaskets. Each head ended up requiring seventeen thousands (.017) of material removal from their surfaces in [...]
