Sabroe Replacing cast iron clutch between oil pump and crankshaft on Installation guide

  • Hello! I'm your chat assistant. I have reviewed the mounting instructions for replacing the clutch on (T)SMC 100 and HPC Mk4 reciprocating compressors. The document provides detailed steps for dismantling the old clutch and mounting the new polymer one. I'm familiar with the provided parts list and torque specifications. Feel free to ask me any questions about this device.
  • What is the purpose of this document?
    Do I need to remove motor fuse before start work?
    What is the tightening torque for the screws, pos. 7C-1?
    Which Loctite is recommended in this document?
    What is the tightening torque for the screws, pos. 11C-1?
