Gradall 534B (9020-7317) Service Manual - Manual (Page 212)

NOTE: Clutch return disc spring packs are certified according to compression weight
specifications and are pre-packed in quantities to repair one (1) specific clutch.
The disc spring packs are to be used as complete assemblies and care should be taken not to
intermix the individual disc springs with disc springs in another clutch or disc spring pack.
Each disc spring assembly is made up of selected springs to precisely match each part within
this assembly. Failure to replace all piston return springs can result in unequal deflection
within the spring pack. The result of this imbalance may adversely affect overall life of springs.
