I accidently broke the bolt that holds the speed sensor in its place :o| . I ordered the new plate and two rivits. How difficult is ths going to be to replace? I assume the driveshaft needs to be removed to repair. Any help will be greatly appreciated.
 
Try a reverse twist (LH) drill bit. They turn counter-clockwise as they drill into the work piece. Center punch the remainder of the bolt and have at it.

If the bolt hole in the drive shaft is deeper than the threaded portion of the orginal bolt is long, and the threads are free of threadlocker or corrosion it shouldn't give you much of a hard time. It should spin out without much torque applied.

I had this type of approach work excellent with broken strater mounting bolts on my both I/O boat motor and on my wife's touring sled.

If you have threadlocker on that bolt, I'd reccomend drilling it and utilizing a fluted pound-in EZ out or a reverse threaded type EZ out.
 
These bolts are tack welded to a plate. The replacement plate comes with four new bolts already in place. I was thinking I may be able to drill out the hole and just replace with another bolt. It only has to hold the top porton of the speed sensor. The speed sensor has two bolts that hold it in place.
 
Did you break one of these bolts?

That would be correct snowmobileaddict. The two rivits hold that plate on. Wow that sled looks clean in that photo. My 09 looks like that with 1200mi on it, My 06 not so much.
 
You do have to remove the driveshaft.

That means, the entire chancase has to be pulled. Get a block of 3-4 hours, some cold beverages and get to work. You shouldn't need many specialized tools.

The big nut on the jackshaft on the chancase side takes a 36 MM deep socket. I'm pretty sure that was the only tool that I didn't have on hand when I helped my riding buddy tear his down.

Thats what I was afraid of. You dont think I can drill it out? Thanks for the info.

I'm confused on what you ultimately want to accomplish. You said that that you bought a new plate with the 4 studs attached to it. See photo below.

In order to replace that assembly, you will need to removed the driveshaft.

If you want to perform a creative repair, you may chose to drill out all the remnants of the broken stud and install a bolt and nut at the that location. I'm not sure how much clearance there is between the outer-most track driver and the side of the tunnel to fit a bolt into that hole with the driveshaft in place.

You might have to place the nut on the inside of the tunnel and have the bolt head on the outside of the tunnel.

I purchased the part just in case. I think there is enough clearance behind the tunnel to install another (I believe it's a 6mm) bolt. If not I will need to go 36mm deep socket shopping. Thanks again for the assistance.
