sorry for slow response (3) Using the crank shaft bearing tool #7471-B (recommended by Cummins), rotate crankshaft to align damper TDC mark to 12:00 o’clock position. a. If both number 1 cylinder rocker levers are loose, continue to next step. b. If both number one rocker levers are not loose, rotate crankshaft 360 degrees. (4) With the engine in this position, valve lash can be measured at the following rocker arms: Intake 1-2-4 / Exhaust 1-3-5. Measure the valve lash by inserting a feeler gauge between the rocker arm socket and crosshead. Refer to VALVE LASH LIMIT CHART for the correct specifications. If the measurement falls within the limits, adjustment/resetting is not necessary. If measurement finds the lash outside of the limits, adjustment is required. (6) Using the crankshaft bearing tool, rotate the crankshaft one revolution to align the damper TDC mark to the 12:00 o’clock position. (7) With the engine in this position, valve lash can be measured at the remaining rocker arms: Intake 3-5-6 / Exhaust 2-4-6. Use the same method as above for determining whether adjustment is necessary, and adjust those that are found to be outside of the limits.
Like that you actually gave the gap sizes and the sequence! That blue color 05 is a classic, nice rig! Thanks for the vid.
Tanks for the feedback hope it helped
Nice man. First video that actually helped
You answered the important questions for me. Thanks man
Cummins has companion cylinders, that's why it's weird which ones you adjust
Good job you gave me Confidence on doing it myself
Thanks appreciate the feedback
Thanks for taking the time to make this video 👍
Your welcome thanks for watching
Also note... it's not "bottom dead center", it's top dead center on the exhaust stroke, versus top dead center intake stroke.
which valves can be done at tdc and which at bdc?
sorry for slow response
