Beckett CG10 manual Propane Restrictors, Replacement Part Numbers

Section: Maintenance and Service

Use authorized replacement parts Figure 17 – Gas Gun Assembly Installation only. Restrictors are precision-

machined parts and O-rings are rated for fuel contact. Do not attempt to replicate or modify any parts. Refer to Table 3.

The gun assembly is secured inside the air tube by a spring-loaded

jacking screw. It is spring loaded in order to control the force it can impose on the gun assembly. When installing the jacking screw look inside the air tube to verify that the pointed tip of the jacking screw pin is seated into the small slot on the locating pad on top of the gun. There is also an external verification of correct assembly: when the screw is fully tightened, the e-clip on the top of the center pin should come flush with the top of the screw. Refer to Figure 17.

Refer to Figures 15 and 16 when performing the following steps.
