A MacPherson Strut Compressor, with which a strut may be safely dismantled for repair, employs a fluid operated piston-cylinder, mounted to an adjustable upper platen to provide compression between a push platen and a lower base platen.
Claims5
Apparatus for use in assembling and disassembling a strut assembly of the type having a shock absorber axially disposed within a coil spring, comprising in combination
- a plurality of upright support rails,
- a first platen fixedly mounted to said support rails,
- a second platen slidably disposed on said support rails,
- a plurality of stand-off members depending from said second platen toward said first platen for engagement with said strut,
- an opening centrally disposed with respect to said stand-off members through which a tool may be inserted for disassembly of said strut,
- said first and second platens including means for holding said coil spring in a compressed condition therebetween,
- a third platen slidably disposed on said support rails,
- a fluid operated piston-cylinder assembly mounted between said second and third platens for moving said platens apart, and
- means for fixedly connecting said second and third platens to said support rails at adjustable positions thereon to restrain said second and third platens against movement relative to said first platen.
