Guess what i've been up to this afternoon.....

Suspension rebuild. New seals, springs (both) and oil :rockon:

No turbo :(

Just haven't trouble getting the damper bolt out of the bottom :confused:
 
Air gun and a wooden handle (broom, etc) down the middle of the tube should handle it.

Yamaha does put thread locker on that bolt some some heat might help...

Thanks but i managed with an air gun and compression from the spring.

I must say tho, i am liking the naked look a lot :thumbup:
 
Are you saying you "made some attempt at cleaning that caliper?" :eyebrow:
YIKES!
 
Never said i was cleaning it ;) That's 37k of dirt !!

I only replaced the seals

YIKES!

It's your life man..... Obviously it matters not what I say, but I can't imagine getting that back together WITHOUT KNOCKING the dirt on the outside, into the caliper which ultimately **may** have consequences.

I'm just saying it it were mine, I'd spend some time cleaning them. S1s are cheap on fleebay...
 
Brake parts cleaner is cheap and so is an old tooth brush! I guess you are looking at new calipers anyway though now. Did you drop it? Kinda scary that caliper iron is so brittle.
 
I did give it a little clean with a brush and some brake cleaner.... obviously not enough for some ;) I also cleaned the pistons and gave it a good blow with the air compressor.

Nope, didn't drop it. It just broke as i was tightening it up to 40nm.

I'll play my Mechanical Engineering degree card here...
Looks like there is copper anti-seize on the threads, is that right? Bolt torques are specified based on a certain thread lubrication to get the appropriate loads on the bolts and the threads. The manual specifies 40Nm DRY. So if you use a lubricant such as anti-seize or loctite, that same 40Nm is actually putting a higher stress on the bolts and the threads than if it was dry. To get the same bolt load and stress, you would need to decrease the torque if you're using a lubricant.
 
Odd to break right there.

The threads look fine, looks more like it cracked as if something hit it, was in a vise, or ?

Was the surface (brake bracket) you were bolting it too, nice and clean, no obstructions???

Wtfff.. can't believe that broke like that. I would think something would strip out first

Nope, no vice. I did all the work on my bench while it was loose. No clamps or anything.

It doesn't bolt to anything. Its for the slider pins.
