bag pinning...re-dux
place the bags on the bike, observe the location I showed with relation to the "ribs" on the bag lower yoke, spot the position. pre-drill the first hole using a 1/8" dia bit, this allows you to spot the hole, drill the guide hole, and remove the bags for drilling thru the mount easily with the correct bit.
I'll say right now, if you have a huge drill, you may have a problem getting the hole that spot.... I used my air powered drill, it's very compact, and small, and allowed me to drill this with the bags in place without a problem...My electric drils would not be able to drill that hole beacause they are just to clunky and big...solution? maybe a reallly long drill bit? Or, use a dremel with a 1/8' bit to do the initial locatin and spotting holes (you'll never drill thru the tough aluminum of the bracket with a dremel, that stuff is TOUGH...) Use new, sharp bits for precision, ......
before you drill anything insure the 2 screws that hold the plastick "puck" onto the mount are securely tightened, this insures a good and consistant assembly.
Drill to final diameter using a 3/16" diameter bit, do not get "sloppy" and rotate the bit and drill around, drill straight thru, this insures a tight interface to keep the pin in it's happy spot. The pins have a ball detent to reduce the chance of backing out, but after hours of banging around they do move...just check them occasionally, and push them back in firmly if they move.
I got these pins from McMaster-Carr, a great source for "stuff" you may need to fix a bike, modify anything, or get any freaking tool you need....they ship fast, cheap, and sometimes for free...I have had parts from them delivered within 36 hours of ordering...they rock!
I ordered 4, just because I wanted spares.....
http://www.mcmaster.com/#98320a020/=ci7v7g98320A020 4 Each Zinc-plated Steel Ring-grip Quick-release Pin, 3/16" Diameter, 2.0" Usable Length
they are now $1.47 each, if you buy 2, shipping is the same as if you buy 4....
I got these for IIRC $8 delivered, within 40 hours of calling.
