What I did over the past week XXXVI

Home:

  • Mounted a 44-drawer storage unit above my workbench in the garage, and emptied and sorted over half of my "miscellaneous jars" (and a bunch of other packages of doodads) into properly labeled drawers. Most of what remains is a large pile of loose screws. I have mixed feelings about this; on one hand it's clearly a huge and necessary organizational improvement. On the other hand... this is one of those "I'm officially old" milestones..

Vehicular:

  • Got the WRX's air conditioning system back together, evacuated and recharged it, and now it's blowing properly cold air for the first time in many months. This was just as much of a PITA as it was when I did this about two years ago. While time will tell if there remains a slow leak, it's clear that if I'd used the OEM o-rings the last time this repeat ordeal wouldn't have been necessary. Bleh.
  • While hunting for a dropped o-ring, I discovered one of the WRX's front sub-frame mounting bolts had backed out about 1/4 of an inch.
    Yowza. Checked all the others.
  • Wrangled the rudderless RTV900 into the garage so I could replace the blown high pressure power steering hose. I'll pick up the final hose in the morning, and the plan is to get it back together over the next couple of evenings.

Rockbox

  • Reviewed more patches; I hope this increased pace of contributions continues!
  • Got the xDuoo X3II working with inline remote controls.
  • Consolidated and sped up some battery query code on the Hiby-based players.
  • Made the powersave-disabling workarounds for the FC1307A ATA->SD chipsets (as used by the popular iFlash adapters) more nuanced so that we can properly power down the entire ATA subsystem when idle.
  • Quality-of-life improvements to daily build download page.
  • Key map improvements to the X3ii, X20, and EROS Q/K.

Printing

  • The Kodak 8810 now supports panorama print sizes (8x14 all the way to 8x36). Untested.
  • Added backend support for the new Fujifilm ASK-500. Untested.

Beauty beneath the skin

This is what my Kubota RTV900 looks like under its skin.

Last weekend, when doing yard work, I lost steering control and nearly hit a tree. To make a long story short, the high pressure hose feeding the power steering sprung a major leak. In keeping with the RTV's tractor underpinnings, its steering system is purely hydraulic, so no pressure means no steering.

In the grand scheme of things this is no big deal; the replacement hose was about $40, but it turns out that in order to replace that hose... a lot has to come off:

The roof, auxiliary lights, windshield, front half of the roll cage, hood, front cowling, steering wheel, dashboard (including all of the electrical connections), floor mat, part of the floor, backrest, seat, seat belts, fuel cap, both side covers, center cover, air intake, air filter housing, and another cowling covering the hydraulic pump. Phew.

Given the equal vintage of the other hoses in the steering system, I decided it was prudent to go and replace everything since I had it all apart anyway -- which meant also removing the engine coolant reservoir, power steering reservoir, and finally, the "steering controller" itself, just so I would have enough clearance to access its rearmost fittings.

I took this photo after replacing four of the five hoses, including the one that blew. Once the fifth hose arrives (on Monday) I'll hook it up, refill the hydraulic fluid, hook up enough of the wiring to get it started, and if there are no leaks, put everything back together.

I had a major setback though; after I'd removed the busted hose, I heard a metallic clunk like something had fallen out. I didn't see anything obvious, but looking at the service manual it looked like there was supposed to be a check ball. Two hours later I found the ball bearing on top of the strut tower, but that wouldn't stay in. So after finally hunting down the OE service manual for the controller, I realized the "ball retainer" doodad was also missing, and most likely hidden in the substantial pile of rust, paint flakes, and other detritus around the RTV. After sweeping it all up and carefully sorting through the piles, hours later I decided to take a second look around the strut tower.. and found the missing part peeking out from the front frame rail, visible from only one side. Had I not found it... suffice it to say the PITA factor (and/or outright dollar cost) would have gone way up. I got lucky!

But yeah, there was a lot of rust. The center panel is solid, though one of its bolts had seized and needed to be cut off.. but the panels to either side, especially the driver's, have some major rust holes. There's nothing to be done about this in the short term, but perhaps fabricating some new panels will be the excuse I need to finally buy a welder? Thankfully the frame is sound, so this workhorse still has a long life ahead of it.

EDIT: Rewrote a bit of this to flow a bit better. And to spell 'reservoir' properly.

EDIT2: I fucked up, big time. When reassembling the dash, I forgot to reattach the air filter before cranking the motor and it ingested a nitrile glove. I'm pretty sure the head is toast, but I'm not holding out hope that the bottom end escaped unscathed. I'll know more when I get the head off.
