DETROIT DIESEL Series 60 & Series 50 Camshaft Timing Specifications Manual 2008
SERIES 60 DIESEL VALVE LASH, JAKE BRAKE LASH AND CAM TIMING SPECS
Camshaft timing, valve lash, injector height, and Jake Brake® lash are all very important
specifications that must be followed closely in order to optimize the performance and service life
of any Detroit Diesel engine. We have assembled four charts that bring together essential and
current information for servicing the Series 60 and Series 50 diesel and gas engines. Most of
the models listed in the attached charts are on-highway applications, but there are a few listed
for off-highway. The attached camshaft timing charts should prove very helpful when servicing
these engines.
Note: If the valve cover option label is missing, illegible or incorrect you will need to check to
see what camshaft is in the engine. To determine the camshaft that is used in the engine check
the part number stamped on the rear face of the camshaft or use DDCSN to enter the engine
serial number. DDCSN will retrieve the model number which will provide the correct injector and
valve adjustments.
