Problems shifting - Lube shifter and brake pivot

Don't use the old Allen wrenches. Very hard to get enough torque to loosen anything, because too short. First thing to try is removing with a proper set of tools. Since the Yamaha uses a lot of hex head bolts, good idea to buy a good quality hex socket set. Impact sockets preferred. May be too late if the head is stripped though, then drilling may be the only option.

Thanks....I was thinking about using a Dremel to carve out a place to use a chisel or a screw driver....but I need to know how that bolt is shaped. I don't want to damage anything.

Get a replacement bolt first, decide how to drill it/notch it, then do the work. You're gonna need that replacement anyway.

Yep... That's the plan. Just gotta find the bolt.

You will need to drill and tap threads into the shifter.
So you don't have to drill such a large hole in the shifter to tap it, they make ones that press in and the hole only needs to be around 1/8 or 3/16 dia.

I think you're making this a lot more complicated than it needs to be. Get a hold of it with a good set of channel locks and it will turn out. If you don't want to make this into a Class A FU, leave the hammer and chisel in the tool box.

Here is your answer -- If more is needed get a helper & a new allen wrench & use channel locks & allen wrench. They make 6mm allen in 1/2" drive - Hard to find but I got one to remove bicycle pedals.

Seems like an EZ Out would be worth trying - Might could put one in a reversible drill.
You will snap the ez out putting it on a drill

Drill the head off, remove shifter then you will have the stud to grab onto.

I think you are right... I just didn't know how that bolt was shaped and I didnt want to break anything besides the bolt. I will give it a go as soon as I have the new bolt.

Do you realize how big the head on that pivot bolt is? It would take a 1/2" drill bit.
you use the same size drill bit as the shaft not the size of the head. I've done this lots at work on the turbines some smaller and some as large as 6 inch bolt.

Even if you did have to go 1/2 inch it's not that difficult, start with a small drill bit and work your way up.

The head is just barely larger than the shaft. I don't have any doubt you can turn it out with a pair of channel locks, plus most people don't have 1/2" drill bits or the drill to put one in.

I'm just trying to help the guy it's been what 2 days now. You do not need a 1/2 inch drill for a 1/2 inch bit you can buy them with the shank turned down to 3/8". Like I said I've done this at work you cant play about trying this and that when your on an outage that is costing the customer a million dollar a day. Useing an ez out might work but probably not and if it snaps off your screwed.

No worries everyone. I did not mean to hijack this sticky. I will try the least invasive first and go from there! Thanks EVERYONE!

A set similar to these https://www.machinemart.co.uk/p/clarke-pro329-9-piece-38-12-drive-screw/ could be the answer, I've used them many times with great success

Wow... That was fun... Finally got it with vise grips a hammer and then channel locks... See if you notice the culprit...
