Legacy Equipment Spare Parts
Identify the series, size and chamber before checking parts
Metso states that it has held the original Symons cone crusher drawings and product specifications since 1928 and continues to support 2, 3, 4, 4¼, 5½ and 7 ft installations. Omnicone 937, 1144, 1352 and 1560 are also retained here for spare-part identification on older equipment.

FAQ
Frequently asked questions
What identification information is needed to quote Symons or Omnicone spare parts?
Provide the brand, complete model, standard or short-head type, chamber, serial number, drawing, installation position, used-part photographs and key dimensions.
Are Symons parts interchangeable when the foot size is the same?
Foot size alone is insufficient. Standard or short-head type, chamber, age, assembly configuration and drawing revision can change interfaces and dimensions.
Can technical assessment proceed without an original drawing?
Submit the nameplate, general arrangement, installation position, used-part photographs and key dimensions first. These establish whether dimensional inspection, material assessment and manufacture to drawing are feasible.
