Componentsthataretobelubricatedandtoolsusedforlubricationmustbefreeofoilandgrease.
Tools
In addition to the standard tool, special tools are required to assemble and remove some
parts (see Table 15-3). Use adjustable torque wrenches with a stop signal or that indicate the
torquebeingappliedtoachievetherighttighteningtorques.Valvesinlargevalvesizesoften
require tightening torques that can only be achieved through additional torque multiplication
by using a torque multiplier or hydraulic power tool. The required special tools can be pur-
chased from SAMSON.
