2. Move the piston rod up and down to check its operates smoothly without any binding.
3. Play of piston rod
^
Measure the play as follows:
Fix outer shell and fully extend the rod. Set a dial gauge at the end of the rod: L [10 mm (0.39 inch)], then apply a force of: W [±20 N (±2 kgf,
±4 lb)] to threaded portion. With the force of ±20 N (±2 kgf, ±4 lb) applied, read both dial gauge readings, P1 and P2.
The free play is determined by the following equation:
Limit of play. Less than 0.8 mm (0.031 inch)
If the play is greater, replace the strut.
