Shocker NXT not firing

[Cdn_Cuda]

Rebuilding a Shocker NXT, o-rings have been replaced, everything seems happy, solenoid goes click but the bolt doesn’t move forward. It shoots a small amount of air. HPR is set to just over 200. Has an HE bolt if they helps.

Any ideas? This is my first time touching a classic Shocker.

check the solenoid insert is not dirty.

the classic shocker resource has a few more ideas.

Solenoid clicks, but bolt doesn't fire.
· Replace the battery (common).
· Verify that your dwell isn't set too low.
· Clean and regrease the firing assembly and solenoid.
· Verify that the solenoid endcap is installed correctly. Parker solenoid endcap has a line that must face the body; Humphrey solenoid has a dot that must face away from the body.

· Verify that the solenoid inserts aren't screwed in too far or too short.
· Replace the solenoid (spool problem).

Thanks! I followed that down the solenoid rebuild and took the bolt assembly out and removed excess lube. Will test again later.

They can be sticky after a rebuild. Try to use a q tip, and really coat/pack everything with grease.

It's easy to miss the inside front can lip oring to.

Also can try to cycle the bolt system assembly outside the body to help lube it.

double check the daughter board on the solenoid and make sure it hasn't been punctured by screws.
