I have a quick way to test the integral fuel lines in diesel heads such as the C15 Caterpillar. I install the fuel injectors to block the ports and attached an air chuck to the fuel inlet. Next, fill the exhaust ports with water and pressurize…

Leveling a head on our surfacing machines can test our patience at times. We are placing a perfectly flat level on a surface that may be anything but flat. Sometimes the solution for a really twisted head is to place precision parallels on each end of the head and level…

Mounting certain heads in a seat and guide machine can be difficult. This is especially true if the heads are uneven or the head bolt holes aren't at the same height. I have a few pieces that came with the machine but they don't solve all the problems.…

Sometimes it’s hard to get a caliper in to get a quick spring installed height. Machine a piece of tubing or rod with a 3/4” I.D. and approx. 1.25” O.D. Make it exactly 1” long. Install a valve, drop in your bushing, a retainer and a…

When cutting in valve seats with a single, multi angle blade, especially new ones, try to do the least amount of work with the profile tool as possible. For instance, if the bottom angle is 75°, cut as much of the seat away as you can with…
