7.13A CHANGING THE URETHANE SPRINGS
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 27 ON PAGE 61. The springs should be checked periodically. (A sure
sign of over stroking is cracking or splitting of the springs.)
Secure the unit in a vise by clamping the bottom plate (item 11).
Loosen and remove both nyloc nuts (6). When loosening the nyloc nuts (6), if one or both tie rods
become loose, remove the loose tie rod(s) from the base plate and remove the nut(s) from the tie
rod(s). Re-tighten the tie rod(s) into the base plate and lock in place, using a thread locking
solution such as Nutloc.
Remove items 1 and 7, top plate and spring spacers.
Remove item 3, urethane springs.
Re-assemble the unit with new urethane springs and finger tighten both nyloc nuts.
Tighten both retaining nuts to achieve the correct setting distance.
