Norgren relay/valves

[robertglines1]

To those of you with tag lift using norgren relay/valves. Just wanted to say before you lay out 180$ for a new one .  take it apart it is very simple spool system with o rings. There is one that is 3/16th wide on most of the spools that is a little more pricey than the rest at  45 cents. Total parts cost to rebuild. $1 or less. I use lithum grease when reassembling. The o rings get brittle after years and start to leak or break and really leak or send false signals.  Just thought I would mention this while it is fresh in my thoughts.     Bob
