Delco Remy Ignition Distributor and Governor (Continued). points, and the spring on this arm had weakened to half the poundage of the other one. The other contact-breaker points, bush and spring were in good condition. Considerable lost movement on the automatic advance was due to the governor springs which did not return the cam-piece to zero. This was due to stretched springs, or springs which were too long initially, not to stiffness on the pins, which were in good condition. Wear on the main spindle and bearing was normal and lubrication appears to have been better than usual. Excessive wear had occurred in the alum. base, causing the whole unit to "wobble". (A backwards and forward movement of .025" was obtainable, measurement at the top of the governor body). This point has been raised on previous occasions and requires attention. Flywheel and Clutch LOP.GB.2100. The clutch was in good condition throughout, the compressed thickness of the friction-plate varying from .306 to .315", representing wear of .024" - .015". The friction surfaces of the flywheel and pressure plate were good and wear on the driving lugs of the latter was normal. The flywheel teeth were rather badly damaged by the starter pinion. ----------- E L E C T R I C A L. Coil. Delco Remy coil failure investigated and found to be due to an open circuit in the primary winding, the wire breaking at the joint of the secondary and primary windings. continued. | ||
