Rear prop shaft installation
We got our repaired rear prop
shaft installed on the ATV today.
I decided to replace the pin
with a bolt and locking nut.
Next up is to figure out why
it won't start.

Thank you David and Jim, your comments really help me when I'm trying to figure out these things.
I think it might be wise to get a higher grade bolt. The one I got at the hardware store is clearly cheap and low grade.
Mark,
The best bolt for this is a shoulder bolt that is slightly smaller than the hole.
The splines will carry the torque load, but the pin has to carry any loads along the axis of the shaft. That shouldn't be all that much (otherwise a spring pin would not be sufficient) but the round shoulder of the bolt is much better at carrying shear loads without deforming than the thread surface.
Do the cross-pieces in the universal joints have a grease nipple?
If not, you can get aftermarket ones that do. Instead of disassembling the joints to lube it you than just give it a squirt with a grease gun.
