48V LiFePO4 Battery Repair, AKA: Something goes right for once this month

Amidst countless failures this month, most of which to do with my VW Golf, and will be saved for another post, I was successful at recommissioning my 48V bike battery.  And I'm pretty psyched about that, since a new one would have been well over $500 shipped.  Let's have a look at the story.

48v Bike battery pack investigations

As I think I mentioned a few posts ago, my 48v bike battery seems to have a problem with cutting out under full throttle.  This is the case even immediately after charging.  I haven't known much about the battery pack, since I bought it used and it came with no documentation, but after reviewing lots of eBay auctions selling similar items, I have a pretty good guess at what I'm dealing with.  I think I've even figured out what happened, and what to do if there's any chance of fixing it.

The Probe awakens early from its winter nap

Well just when I thought I'd finally gotten past this auto maintenance nightmare... What was only supposed to be an exciting couple of weeks in incoming baby-world (my wife is due next weekend), I have spent basically dealing with my cars.  I'll try to summarize the story as simply as possible.

Windows 8 audio clicks and glitches narrowed down to Malwarebytes

Ever since I got my Windows 8 PC, I have been having serious problems with audio.  Basically all sound playback on my system experiences a brief  but frequent click, skip, glitch, stutter, whatever you prefer.  I can reproduce the issue on any sound card or firewire sound interface (devices tested include the onboard Conexant SmartAudio HD, my external Phonic Helix 12, and my Edirol FA-101).  All of them seem to have audio clicks, with the firewire interfaces' clicks seeming more harsh for whatever reason.

Seal replaced, back on the road!

Last night things moved ahead considerably.  I was very happy to see that the replacement seal arrived priority mail (from - they've never done me wrong) on Monday, after I ordered it on Friday night.  I also went out and found a seal puller (similar to the one pictured) at Sears, of all places.  None of the regular auto parts stores carry this thing for some reason. The elusive seal puller I finally obtained.

Gears replaced, leak found!

Well, I was going to update this the other night, but sometimes there's only enough time to work on the car.  So a few things have happened since my last post: for one thing, I got the old gears off.   

Torn up gears, and a dead end for now

Well today I got the transmission cover off.  There were two gears in here (5th gear and the selector gear) that were totally rounded (all teeth were sheared off).
