SEE FIGURE 32
If the unit is constantly over stroked or over a period of time, it may be necessary to renew the urethane
springs. REFER TO FIGURE 32. The springs should be checked periodically. (A sure sign of over
stroking is cracking or splitting of the springs.)
1.
Secure the unit in a vise by clamping the bottom plate (14). Loosen and remove both nyloc
nuts (8) & retainers (10). If one or both tie rods (13) become loose when loosening the nyloc nuts,
remove the loose tie rod from the base plate and remove the nuts (8) from the tie rod. Re-tighten
the tie rod into the base plate and lock in place, using a thread locking solution on the set-screws
(15) such as Blue Loctite. ®
2.
Remove items (10) and (8), top plate (1).
3.
Remove both of the urethane springs (11) and spring spacers (12).
4.
Reassemble the unit with new urethane springs
6. Tighten both retaining nuts (8) to achieve the correct setting distance.
