Reconditioning
Note:
Jig details are in accordance with ram sizes.
Procedures for inserting and bedding the seal ring.
Stretch the 'O'-ring by hand and fit it into the piston
groove.
Be sure not to twist the 'O'-ring. A twisted 'O'-ring may
cause oil leakage.
Fit the inner guide jig on the upper section of the piston.
Carefully fit the thinner end of the inner-guide jig on the
upper section of the piston.
Apply a thin coat of lubricant to the inner guide jig
periphery and then set the seal ring on the inner guide jig.
Make sure that any foreign matter like dust, chipped
metal and lint do not adhere to the outer surface of the
inner guide jig.
