Hi all, I am in the process of rebuilding the CAV injector pump on my 1974 Ford 2000. All seems to be going well, but I just want to double check on one thing: After disassembling the endplate, cleaning, replacing the screen and gasket, then reassembling it, I can shake it and hear what I assume is the piston (#3) move back and forth inside. Is that normal? I've gone through it twice, and everything seems to be in the proper order, but I cannot rule out a screw up on my part.

Just want to be overly cautious. Thanks!
