Does anyone happen to know the size (and pitch) of the oil drain plug on a Harbor Freight blue 6.5hp clone motor?
Are you talking about the plastic drain plug, with the filler/dipstick type cap?
Or the one further down that looks like a 10MM hex socket, or bolt at the bottom of base?
I should ask. What are you trying to do? May be I can help.
It’s a straight thread 10mm x ?. Probably 1.5mm, I’d have to check.
