Oil Drain Plug Hex Size..?

Discussion in 'Technical Help' started by Monkey, May 18, 2020.

  1. Could anyone tell me what hex size socket I will need to drain the oil from my ST4 2004..
     
  2. I can't recall off the top of my head but (I think it's 14mm:thinkingface:), if you still have the original tool kit there should be a tool in there that fits it.
     
  3. 14mm but it tends to be a sloppy fit. 1/2mm bigger would be better.
     
  4. Thanks for the information .......
     
  5. 9/16" might fit the bill.

  6. I was going to say that but couldn't remember what 9/16 is in metric. I think it's pretty near 14.5mm
     
  7. Just under 14.3
