I have taken apart the sled to do the donuts and the 2 bolts holding the Y pipes on 5mm allen are seized/rusted. The heads were cut off and now I need ti get the bolts out. Any suggestions? Thanks

Mine are also seized up. I tried heating them up first and then spraying PB Blaster on them and then heated up again and when I tried to loosen them they just stripped out the head. Mine are not moving at all and I fear if I try to drill them out or use an easy out I'll end up breaking that off in the screw as that always seems to happen to me. There is not enough room to get a cut off tool in there so does anyone have a good way of removing these? I usually pound the next closest size allen in there but that is not working either.

When I replaced mine , I sprayed PB blaster on them then stripped the head out, so took a 3/8 drill and drilled the head of the bolt off, once I drilled them they released and turned the stud out by hand. There is enough thread to double nut on the bottom side if you pull suspension out, also after you remove headers try welding a nut to the top of thread, this will put heat on it and also something to put a wrench on.When I put the new bolts in I used the bolts off the old style brake caliper on the proaction chassis, 8mm stud with a 10mm head. So now you can use a 6 pt socket to remove them rather than a small allen wrench.

sometimes you can soak over night, then when you get ready just don't try to turn them, snap real hard fast.

One other trick, if you have a mig welder. Take a 3/8" or 1/2" nut and weld through the center of it to the allen bolt then loosen it right away. The heat from welding and the use of the nut works for me, most of the time.

Next time you have a rusted nut or bolt take a propane torch, adjust the flame to a small point and heat up the bolt for a few minutes and wah lah, the bolt comes loose. I fought with those same Allen bolts on my sled for 20 minutes and after heating them up they came right off.

Yep, same with me. stripped mine, drilled it out, heated it up and easy out worked real well. Must use heat! couldn't move without it.

Thanks for all the tips guys, but if you read my post I did heat them up then I let them cool off and sprayed with PB Blaster then I heated them up again before even attempting to loosen them and they just stripped right out. They are seized up tight and I tried my Grab it tool which is a tool that is like a counter sink on one end and the other end is like an easy out and it will not even make a dent in the bolt. But at least I can see all 4 of my donuts are pretty much shot. I started hearing them on my last trip about the second day and rode over 850 miles after hearing them leaking. It still ran good no back firing at all but I could hear the leak under the gas tank. Any way thanks again for the tips.

Use a 6.8 mm drill and drill the bolts out and run a 8mm tap in the holes,

I just did mine on my 05 RX1. I heated one at a time and used a air chisel with a regular chisel bit and broke them loose. Then they came out with a left handed drill.
Did any of you have a problem pulling your exhaust pipes off of the bac of the Y pipes? I had to heat and pry and hammer to get mine off. The pipes are very strong and it did not hurt them but it was a real pain. Then getting them back on was no fun either. I think I should have expanded them first.

Had the same problem on both my 06 Apex machines. Drilled out the 10 rivets which hold the bracket for the pipes, slid back the exhaust/muffler, replaced the donuts pushed back the pipes, reclamped, and re-revited. Works just fine.

Re: Exhaust
Had to do the same thing. Not a hard job. Took the bracket right out, put it in vise and heated and removed bolts. Riveted bracket back in place and reassembled using hexhead bolts.yamadooski said:

I'm with PolarisConvert on this one. Never underestimate the power of an air hammer. A pointed chisel bit will easily dislodge rusted in bolts, spin seized bearings on shafts etc etc. You may have to replace the bolts when done but often they can be reused provided they're not already stripped. Just carefully hammer on the top edge in direction of rotation with a pointed bit to get it spinning. It'll turn right out.
Often this will save you a ton of work. Most air hammers have an air adjustment so start on the lowest setting. You have to use some finesse as you can easily over do it but with a little care they are an invaluable tool.
