Hi Gang, I need a suggestion for getting out the right front hub oil screw (Allen wrench style) on an old 93 Polaris Trialboss 350L. This looks like a big set screw and I keep rounding off my Allen Wrenches trying to get it out.
I do know it has that magnet on the bottom, so I don't want to ruin it. I've let it set for weeks with a break-free compound on it, but nothing yet. How would YOU get this out without ruining it?
thanks!

I might try a screwdriver type allen wrench( not the angled type) and bang on the handle with a hammer while un-screwing it to help break it free. Or maybe an impact wrench- would act about the same way- but more risk of stripping the screw. Good luck.

 

Use a easyout and buy a new plug.

 

If you can't break it free with a wrench- an easy out will never work.

 

I figured he stripped out the plug, thats why I said to use a easyout. If it's just stuck, take a little heat and put it on the housing just around the plug. That should do it.

 

I have had to drive a small chissle in the rounded out hole cutting into the screw and use vise grips to back it out.Then get a new plug.You may have to run a tap through the threads afterwards.

 

Like I said before. Use a little heat and a easyout should do the trick. Just don't get crazy with the heat.

 

What are you using on it? Liquid wrench works good. So does BP blaster
Try also using a small hammer and a metric allen key. If it stripped already a metric might just fit.

 

Thanks Guys, I have tried to be careful not to round out the inside of the allen type screw, but it has rounded off my hex heads, and I can't get anything to fit it right.... nor the metric size to fit where I can get sufficient torque on it.
I was using liquid wrench on it. I'll clean that off now, and add a little heat around the outside of the hole, but I don't want to strip thread. If push comes to shove, then I'll just use an easy out and get a new plug.
thanks guys!

You might want to buy (or borrow) a hand impact tool. You put the proper size hex head socket on the end of the tool. As you hit it with a hammer, it automatically turns the fastener. Works well.
