Before you order: confirm fitment

  • Check the engine tag on your Miller Electric machine: it should read CH440-3170 / PA-CH440-3170 or an older spec this engine replaces (CH440-3139).
  • Match crankshaft diameter and length, mounting pattern, PTO/clutch, fuel and wiring connections.
  • Not sure which engine your machine has? Call (646) 666-7225 with your machine model and serial number and we'll confirm the right spec.
