Durant all Models 1928-29.--To check the valve timing set the tappet clearance of No. 1 cylinder exhaust valve at .008". Crank the motor until No. I exhaust valve just closes. At this point, the flywheel mark EC-1 should appear at the indicator of the peek hole in the flywheel housing. On models not equipped with an enclosed flywheel, indicator for valve timing is the centerline of the last cylinder. Durant Models 6-14 and 6-17 1930.--To check the valve timing use the procedure given above for previous models with the exception that the tappet clearance for checking timing should be set at .012" for Model 6-14 and .010" for Model 6-17 (see valve tinting table for timing data).

Durant Model 407 1930.--To cheek the valve timing set the tappet clearance of the intake valve for No. 1 cylinder at .012". Crank the motor until No. 1 intake valve just starts to open. At this point, the flywheel mark indicating top dead center of pistons 1 and 4 should register with the pointer of the peek hole in the flywheel housing.
