Greetings,

I got a Simplicity sno-away 8HP 2-stage snowblower and try to open the plug on its gearbox to check its gear oil level. I used a open wrench to turn it counter-clockwise and the plug wouldn't move at all....used W40 and tried again...same thing. Is there anyway or any tool someone can suggest?

btw,the plug is in square shape and approx. 9mm.

Thanks in advance.

 

Someone suggested to use LiquidWrench and I will give it a try tonight.

 

WD40 isn't very good on loosening things. LW or a product called PB Blaster (supposed to be even better than LW). May take multiple applications. Don't forget to tap the parts after application.

 

GunGuy is right on with the PB Blaster.I used it on a piston with a stuck ring, Put the piston all the way down and shot the cylinder full of it. Let is set a few days and machine (Generator that had set for 3 years)was up and running. Great stuff.

 

In any business, tools are the key to effective service; you need a square or double square socket. If you've rounded the plug you will now want to file it back to square so the socket will engage it well.

 

I tried the LiquidWrench but didn't work. I will give it little time to soak and try it again tomorrow.
By the way, where can I find the square/double square socket?
thanks.

 

Just about any autoparts or Sears store, but you sort of have to know the size of the square on the plug. Sometimes you can use an extension for a socket set, usually a 1/2" set that might fit the plug, if not I go with what was previously suggested. Maybe a vice grip might work.

after let LiquidWrench soaking for 24 hrs, I was able to loosen the plug by an adjustable wrench.
Thanks!
