It's coming along! Had to extract 3 bolts tonight and they all went pretty smoothly; no broken drill bits.
I found out what the plastic piece I was questioning was for. It goes on the shift shaft as a spacer. I just sheared off the bolt that holds the chain tensioner lever in place on the metal spacer. Can anyone explain to me why a bolt will continue to torque until it snaps when you have the proper torque set? Is it just worn? Luckily I got it out and I'll just head to the hardware store tomorrow to get a replacement. Glad my threads weren't damaged because that's the whole reason I'm in this predicament in the first place! Does anyone know what kind of metal I need when buying the replacements? I need bolts for the head that hold the top bearings of the camshafts on and the silver bolt I just sheared which held the tensioner lever in place. Still curious why the engine was overheating in the first place as all the passages have been fine... Perhaps it was the oil itself? I do drive the bike very hard so who knows.... I'll be sure to order a new thermo switch this time as that is suspect in my eyes.

Also, how do I re-torque that bolt that is on the alternator side of the crankshaft? The one you use to turn the engine over manually....??

I'm not sure why you are breaking off bolts. The bolts they use are special in that they break before damaging threads. So whatever bolt you replace it with needs to be soft steel. Don't use a hardened bolt.
Sometimes the bolts are damaged by overtorquing but don't break until later. It could also be that you are using the wrong scale on the torque wrench (ft-lbs instead of in-lbs, etc.). Or you are using the wrong torque value. Or the wrench isn't accurate. The alternator bolt is only 50 ft-lbs and is pretty easy to torque. Just make sure the key is in place and all the starter gear stuff is there too.

I believe this is due to "necking" of the bolt, where the threaded area literally stretches and arches. Furthermore, i wouldn't buy anything from the hardware store to replace internal engine bolts. I got all my bolts from the dealer, yes it was a wait, but i can trust that when i put it back together, it was to manufacturer spec. |

I know to keep spare bolts on hand from now on at least. It's coming along quite well I'm currently just extracting ANOTHER screw. This time it is out of the water pipe where it attaches to the impeller housing. Got the head all together for the most part with valve clearances done. So much easier when the engine is in your bedroom instead of out on the street might I add. I just need to throw the shift shaft in and connect it to the gear drum and re assemble the clutch.

Just wanna verify the thrust spacer part no. 92026 is facing the right direction. It's larger side is supposed to face outboard correct? Almost like if it was an arrow it would be pointing inwards towards the bike? I don't have enough room to thread this nut on all the way onto the hub.... Not sure if that's just how it is.. 2013-10-05 15.51.39.jpg Edit: Nevermind the nut the oil pump gears weren't meshing. I still need confirmation on the thrust spacer sticking out all weird though.

Just broke the clutch hub trying to torque the nut on. Anyone got a spare for sale?
part no. 13087 Does this piece spin freely in gear or does it lock? Is it safe to torque it with the bike in gear?

Your picture doesn't look right. Starting with nothing but the engine, you want to install...
1. Beveled washer with small end pointing into engine. 2. Cylinder shaped bushing with a snap ring. 3. roller bearings over that. 4. Clutch basket over that. 5. Rear clutch hub. 6. Washer 7. big nut. The big nut is supposed to be replaced every time you remove it. Make sure the cylinder bushing thing with the snap ring is pointed the right way.

The internal hub goes to the transmission and the outer clutch basket goes to the crankshaft. Also be careful not to misalign the clutch basket gear with the oil pump gear or else you'll bend the oil pump shaft and need a new one of those too.

if it doesn't go down all the way the washer behind the hub is backwards or the oil pump isn't lined up

Is it safe to torque with the bike in gear or should I just buy the tool?

100# is more than enough to move the engine (trust me i know this from trying it)
get the clutch hub vice ($10) and get an impact wrench ($25)

Actually, an impact wrench is good for removing it, but not putting it back. You need a torque wrench for that.
If you had it on the bike and had some way to put the brakes on, you could use the transmission to hold it. When I do it, I use my tool I made and then use a flat screwdriver wedged in between the crank and clutch basket gears to keep it from moving. The main thing is that you need something to keep the engine stable. If you are not in a hurry, I could come over some time with my tool. OR you could just buy one. Clutch Tool

Use the clutch hub tool to hold your stator/flywheel/magnet thing. Expand the tool and have the tool hold it against the projections on the outside of that thing.

Ok I have no idea how to use that clutch holder tool. I'm researching it online right now. Not very intuitive.
I didn't get your idea either @cuong-nutz

Justin, I'm pretty sure that tool goes on the clutch hub side and not the stator. Holding the stator would not accomplish anything. It holds just the inner teeth and not the outer if I am not mistaken.
I plan to be near your neighborhood on Monday afternoon-evening. I can bring mine if you don't have it by then. Mine is different. Its the same one we used to get it off.

Pic is too small haha.
Is one lip on the outer basket and one lip on the actualy hub? If so I probably would have taken a while to figure that out....

Once you clamp it down on the hub, you hold the clutch tool or brace it against something to hold it still while you torque the nut down. if that doesn't help I don't know what else will. lol

I thought I posted this before, but it must have been in another thread.
This is the one I made which closely mimics the EBC one. It was made from a spare steel plate and the extra parts are attached with aircraft rivets not welds. Its perfectly acceptable to use little nuts and bolts too. Its function is to lock the inner and out clutch hubs. Then all you have to do is lock the crank with a screwdriver and torque away. Justin, did you already buy the cycle gear one?

From reading this thread and others. Should have purchased a rebuilt exchange motor.
When people say that the motor has overheated and only replacing one or two parts in the first few posts. You quickly realise not going to end well. Guess not everyone has the skill and a family of engineers and an engine builder. |

For some reason I thought yours was welded together. I don't have a spare metal plate anyhow.

That tool I have is plenty strong and big enough. Unless you're clamping down very tight or have to cocked at an angle, I can't see how you would break anything.
How is the tool not big enough? Can you elaborate?
