To remove NRV 1 unscrew resin recirculation valve swivel fitting and then remove
from top head block. It is not necessary to remove resin pipes. Note, a few drops of
resin will leak out so be prepared with rag. When replacing this fitting, eliminate
traces of resin in fitting with solvent then grease threads before re assembly

Inspect all head block and NRV galleries. If catalysed resin is evident, remove or
replace parts as necessary.


To disassemble all NRV’s, remove spring retaining pin. PTFE cone (0489) can be
replaced by removing spring from seat retainer (0490).

When using a new PTFE cone, press and turn into NRV seat using thumb pressure
only to ensure a good seal. On re-assembly a suitable hook must be used to stretch the
spring sufficiently to enable the retaining pin to be replaced.
