Dear EditoR
Any mechanic who's had to
replace the shuttle and check
valves on the ML±S²s elevation
hydraulic valve module assem-
bly knows just how frustrating it
can be.
When you try to remove the
valves, the cap comes apart,
leaving the plugs stuck in the
module. Then you have to dis³
connect the module and tap the
plugs out´a very long process.
Weµve develoPed a simp¶e tool
that pulls the plugs out every
time· Jus¸ take the cap From a
discarded valve and grind o¹
the outer threads· Then screw it
back onto tHe stuck plug·
Afer
GRind oF outE± Th²eads
on Old sc³ew c´p
With the outer threads goneº
the cap connects to the plug
without attaching to the module.
Then you simply pull the plug
out· If it's jammed too tightº just
use the tip oF a screwdriver to
gently p» it out.
