ABSTRACT:
The roller shaft which actuates a pumping element in a fuel injection pump is secured against unintentional release during transport by elastic elements, preferably spring wire parts, whose one end engages a stationary portion of the fuel supply pump and whose other end engages a recess or cutout in the roller shaft and cooperates with a shoulder or stop therein to prevent unintentional drop-out while permitting a normal reciprocating motion after installation. Suitable openings and grooves provided in the roller shaft guide can hold and orient the spring wire.
