40 THE SHOP OCTOBER 2017 SHOP TOOLS & EQUIPMENT D ynamometer testing a freshly built engine is both exciting and fraught with worry. It's normal to second-guess yourself when preparing for the trip and even during the drive to the dyno shop. Common questions might include con- cerns such as: "Did I torque the crank balancer?" "Did I remember to bring my engine specs?" "Did I pack my EFI con- troller?" "Did I tighten the oil pan drain plug?" "I know my pushrod length is cor- rect, but what if I made a mistake?" "Did I properly tighten my rod bolts?" And on and on. The last thing you want is for the engine to be damaged due to a mistake. You also don't want to be embarrassed at the dyno shop because of a stupid thing you did. Concerns like this are normal, especially if this is your first time taking an engine to a dyno session. To avoid potential mistakes, take the time to methodically make a list of all the items that you need to bring, and per- form a double-check of your engine prep to eliminate—or at least reduce—your worries. Delivering your engine to the dyno facility is only part of the equation. There are other items that you'll need to bring so that the session will go according to plan. You shouldn't need to bring any hand tools. Any competent dyno shop will already have any tools that may be required in order to mount the engine to the stand and to perform checks and adjustments (setting timing, adjusting fuel pressure, fastener torqueing, adjusting a carburetor, rocker arm/valve lash adjustment, checking ignition timing, etc.) However, consider other items as listed here: In order for your dyno session to go smoothly, pre-arrival prepara- tion is vital.

Prepping Your Engine Dyno for the By Mike Mavrigian There's more to it than simply showing up. Always pre-oil any fresh engine prior to the first start. An engine pre- oiling canis- ter provides an efficient method. This Goodson EPL-120 is a good example. Simply add oil to the canister and charge it with compressed air.
