Here's some pics of an inline six cylinder head going through the valve job & surface process. After we machine the intake & exhaust valve seats on our Tobin Arp seat and guide machine the surface needs milling. For machining the surface we mount the head on our Rottler EM105H multipurpose CNC milling & boring [...]
Here's some pics of the main bores of an 855 Cummins diesel engine block getting bored. The block is setup on our Rottler EM105H CNC machine with the RAD (Right Angle Drive) for the horizontal cutting. These pics are after the first pass of machining.

This is a Caterpillar 16G grader axle spindle housing we're repairing. This surface was worn down quite a bit which required a lot of build up. The next step is to mount the spindle housing in our CNC mill & begin the machining & counterboring back to spec. Motor Mission Machine & Radiator 5435 Desert [...]
This is a 7.8 liter Ford diesel engine out of a 1989 Ford F800 boom truck. The engine had been overheated & needed some cylinder head work performed. After we got the engine all together we test ran it multiple times to heat cycle it & make sure it all checked out good. After setting [...]
Here's some random engine projects going on in the machine shop. Various machining operations are happening from cylinder boring & honing, deck milling & surfacing, rotating assembly balancing along with complete engine assembly.

Here are some before & after pics of a flywheel that came in that was badly worn with hot spots. The hot spots on this one looked like they were caused from riding the clutch too much. Gotta keep your foot completely off the clutch pedal as just the weight of your foot will cause [...]
This is a set of Sealed Power Forged pistons. The part number is an L2300NF. These are .060 over pistons for a 427 Big Block Chevy that we are building. These were scarce & a challenge to find. Motor Mission Machine & Radiator 5435 Desert Point Dr. Las Vegas, Nv. 89118 Ph: (702) 649-2366 or [...]
This is a Cummins camshaft that we cleaned & inspected before micro polishing the journals & lobes. Most diesel engines utilize roller followers, or lifters, so the camshaft isn't normally replaced during a rebuild if there isn't any damage. We have this cam shined up & ready for another service life. Motor Mission Machine & [...]
This is a Green Diamond 233 cubic inch inline six cylinder engine block out of a 1949 International KB-5 truck. The four housing bores are all a different size so line boring is necessary in order to get the main bores trued up for the new main bearings. Our newer Rottler cnc machine is down [...]
This is an 855 Cummins Big Cam diesel engine block. The housing bore was damaged so it needed a line bore. The upper counterbores were machined to the proper depths after the deck was surfaced flat & square. A new set of cam bearings were installed after all the machining operations were completed. Motor Mission [...]
