There's Work to Be Done . . .

Oh jeesh . . . OK.  So what's the benefit of having 520 chain and sprocket vs. 525?

Why can't anything in life be as easy as Paris Hilton?

520 is lighter, and won't wear as well as 525 if the bike actually makes enough power to need it, but the real benefit is price.

It is way cheaper than 525.

AHHHHHHH!  Thanks.

I'm guessing my 620 doesn't need a 525

AHHHHHHH!  Thanks.

I'm guessing my 620 doesn't need a 525 

That'd be correct.

[Bendy]

Yar. It'd be overkill, son.

[INFIDEL]

Anyone got a spare 520 master link?  Not sure if it has to be DID or not . . .

[scott_araujo]

Ok, what did you do?

DID is best if you can get it.  The tight tolerances on DID are what make them such high quality and why they last so long.

I dunno.

One pin doesn't look like it's all the way through - or at least not as through as the other.  And then I'm not sure we got them to mushroom enough but can't seem to get them to mushroom more.

I might be just being paranoid since it's the chain and such an important piece.

You want me to return your tools tonight?  I can swing by after 5:30.  Or tomorrow.  Or are you in any rush at all?

Thanks for their use and the hints/tips.  Very helpful! 

[scott_araujo]

No worries, hold on to the tools until your done.  I shouldn't need it for another 9000 miles or so.

So, measuring outside plate to plate, is the master the same width on both ends as the other links?  If so, you've got it together right.

The only other thing I can think of is that maybe one of the pins pushed out the back a little and so now it's not sticking out the front far enough to get a good mushroom.  If that looks like it's the case, press it in to the back again, re-press the front plate back on to correct measurement, and re-mushroom it.

Also, the measurement of the mushroom is REALLY being picky.  Plenty of people just crush it and go with no ill effects.  Don't overthink it.

Ohhhhhhhh . . . I didn't think of trying to push the pin out from the back side!  You so SMART!!! 

I'm not sure about it measuring the same on both sides - I was measuring the middle.  I'll have to do that again.  It looks like it has a pinch point when going over the front sprocket that would/could be alleviated if I push the pin out from the other side.

I'll have to give it another try tomorrow.  I'm kinda frustrated right now and shouldn't go try any more.

Anyone beside me not receive posting announcements.

[GAAN]

I haven't either

I get PM emails but not for posts

[scott_araujo]

Yeah Chuck, measure each side individually.  Otherwise it could be crooked.  And a patient break when you're frustrated is always a good idea.

Scott

[INFIDEL]

I'm good, real good.  Both sides are 16.92.  I got an even press.

The chain links to either side are 17.14. Is a .22 difference acceptable?  After I got the back pin to shroom.  The "catch point" disappeared and the chain rolls smoothly.

Anyone . . . anyone . . . anyone?

[scott_araujo]

Looks like you overpressed just a shade.  It's an x-ring chain (right?) so I wouldn't worry too much if it's not binding so long as you put plenty of grease in there.  If it were me I'd ride it a bit and see how it looks.  If you're paranoid just order another master and install it now that you know what you're doing.

Scott - That is your chain breaker / rivet tool, right? Which brand and where did you get it? It looks like the DID one which is like $150, but there are plenty out there in the $50 range. However, many of them look cheesy or say things like "not for use on bla bla bla type of chain..."  Anyhow, just wondering. Chuck and I were both interested in picking one of some sort up.

[scott_araujo]

Yup, $50 knock off.  Towards the bottom of the page: http://www.mikesxs.net/products-7.html?category_id=7.1

I also got an extra pin just in case it snaps.  I've since found out that if you grind off the rivet head before you press it out that almost never happens.
