The Taos Box

Life has been super hectic lately so Jo and I decided to get away last weekend. We had the outdoors to ourselves because most of the world was working hard and staying home so they could go away on Memorial Day weekend - suckers! I was just coming off a head cold and Jo had been working all week, we were both exhausted and run ragged. After much thought and consideration we decided on Taos, New Mexico. It offered paddling, biking, and a different vibe than most of Colorado's high brow mountain towns. John was headed there from Albuquerque and invited us to raft and camp with him.

We didn't get headed south on I-25 until 8:00pm Friday night. Not wanting to push my luck with the cold we stopped after 3 hours for the night in Raton, NM. We were supposed to meet the Known River Guides rafting bus at 9:00am Saturday morning in Pilar, just south of Taos. We didn't make it to the rendezvous spot until 9:30 after being delayed by a huge POW / MIA motorcycle rally and a warning for speeding (I was only going 9 over). We spotted the Known River bus just as it was pulling out of the lot. John recognized my truck and made the driver pull over. I downshifted into second gear and broke the rear end allowing me to bust a drifting U turn across the two lane road. As I pulled up on the dirt next to the bus the doors opened and the driver yelled at us to "grab your shit and get the hell on the %$! dam bus!" I busted another drifting U turn to the parking lot and we made the quickest egress from a vehicle I've done since I crashed into a gasoline truck as a teenager. In the rush I left my camera, our food, and my dry top all of which I would miss later on. After the adrenaline wore off the entire bus shared a laugh at our dramatic entrance.

The Taos Box is an 17 mile stretch of class III and IV rapids on the Rio Grande river that runs through the 800 foot deep Rio Grande Gorge. The Rio Grande Gorge and Rio Grande Gorge Bridge is the dramatic canyon and arch bridge featured in the recently released movie Terminator Salvation. Once you enter the Box there is no way out, the canyon walls are so steep that even a helicopter evac is out of the question. The water isn't as big as the class V riddled Cheat River I usually do, but it was big enough. After dipping a neoprene booty covered foot into the freezing snow-melt fed water I decided that I did not want take a swim that day.

Jo, John, and I put in in an 8 man boat with the rest of the ABQ crew. Stacy and I were in the front with John and Jo in the "swimmers slot" directly behind us. I've been rafting enough to know if a guide is good by the first rapid and after a few commands in an easy class II I felt confident that ours was dialed. The first half of the Box was pretty mellow with just a few Class III's between long stretches of flat water. The canyon was spectacular with dark lava rock walls that towered from the water's edge straight up to the sky. Lush sage and junipers populated even the narrowest of shelves in the walls with shades of green that can only be seen for a few short weeks in late spring. The desert is magical this time of year and we soaked it in as we drifted in the gentle water between rapids. It was a stark contrast to what lay ahead.

After about 3 miles the a strange linear shadow came into view. It started at the top of the west canyon wall and cascaded down the ledges towards the river as we drifted closer. It was the Rio Grande Gorge Bridge. A huge arch of white steel stretched from an apex of 650 feet down into the black canyon walls. I have been on top of the bridge before, but it was years earlier. Viewing the bridge from the bottom of the canyon, with the distant roar of rapids and occasional arctic water splash brought a realism to the scene worlds away from the sterile abstract view from the road deck. Just downstream of the bridge was Trash Rapid, a solid class III that was littered with junk, cars, and debris that has been thrown, crashed, or dropped off the road above over the years. The rapid itself wasn't anything spectacular, but our guide assured us that this was the least desirable place to take a swim on the river. Just under the surface was a mine field of tetanus filled rusty metal. As we passed under the bridge into the rapid I wedged my foot a little deeper under the side of the boat.

After Trash Rapid we stopped for lunch. I was cold and hungry from leaving my dry top and food during the quick vehicle egress, the latter was soon remedied by the the best food I've ever had on a river. Kudos to the guides for a gourmet lunch of peanut butter and apples, chips, and turkey sandwiches. After lunch the tone of the river changed dramatically. We entered what's called the Power Hour, which is a steady stream (no pun intended) of class IV's caused by much steeper drop in elevation per mile. The river was flowing at 3500 CFS (cubic feet per second), which made the Power Hour more of a power 45 minutes. An ancient F14 (jet in Top Gun) wreckage littered that the west canyon wall was a good metaphor of the carnage of the gravity (also no pun intended) of the canyon. One huge drop after another treated us to thrills and laughter. Each wave felt like a someone throwing a 5 gallon bucket of ice water on my head, but my fear and adrenalin kept me warm. After all my rafting and kayaking over the years I still get scared when I see a horizon line (indicating an upcoming drop) and hear the ominous deep rumble of a rapid on the river.

The Power Hour








Power Line Rapid was the last class IV of the Box. A huge cell that had been following us down the river had matured into full blown thunderstorm, so I was fine with getting off the river. At the takeout our efforts were rushed by lightning strikes getting closer and closer. The bus pulled up just in time. The ride back to the truck was short and the thunderstorm would later dump over 2 inches of gumball sized hail along a swath of New Mexico highway 64. It looked like fresh snow when we drove into to town later adding to the desert magic. The Box proved to be as epic as the rumors I've heard over the years. We had a strong boat with a good guide and no one took a swim, although both Jo and I made a few dives toward the middle of the boat.

Tacoma Mx

The Tacoma is getting close to 200,000 miles. None of the things I blog about (hang gliding, mountain biking, photography, etc) would happen without the Tacoma so I figured it deserved some attention. I have abused it in conditions ranging from aggressive city driving, sweltering desert heat, Arctic alpine blizzards, to 4x4 "roads" to hang gliding sites that a battle tank couldn't get up. I thought a good use of my downtime following my PRP injection (see PRP Injection Post) would be to do a 100,o00 mile service. The list included replacing:

Timing Belt
Water Pump
Thermostat
Power Steering Belt
AC Belt
Alternator Belt
Oil and Filter
Transmission Oil
Transfer Oil
Front Differential Oil
Rear Differential Oil
Brake Fluid
Clutch Fluid
Coolant
Radiator Hoses

After that I installed my freshly powder coated bull bar, front hang glider rack, and driving lights.

My Dad used to say that with the proper instructions, the right tools, and a little confidence you can do any mechanical job. I had never dug that deep into the Tacoma engine before and was a little nervous, but the $2000 Boulder Toyota wanted to do the job was good motivation. I time budgeted a day to complete the job and 6 short days later with Jonny V's help it was done!

Part of the delay was making constant trips to the hardware or auto parts store for everything from replacement bolts, new crush washers, random sockets that I didn't have, etc. Every bolt and nut was seized from a 100,000 miles of heat, cold, and hard use making simple steps take
hours to accomplish.

When I got to the crank shaft pulley I ran into problems. The Factory Service Manual calls for a special tool to hold the crank shaft pulley while you loosen the pulley nut. 4x4 Wire forums shows how to weld the tool up yourself, but I didn't have a welder so I tried to make one out of laminated wood and drill bits.

My Homemade Special Tool




The specified torque for this nut is 217 foot pounds, but after 100,000 miles of use it needed much more to break it. The wood just wasn't strong enough and exploded as Jon and I tried to break it. I've never seen wood fail in this way and energy released as it exploded was impressive. Luckily, no one got hurt!

My Tool After the Explosion


I decided to stick to my Dad's words of wisdom and order the Toyota special service tool. It wasn't cheap, but I was still well under what the dealer would have cost. The nut was so tight that I had to use a 6 foot breaker bar on the tool to break the nut. A Thule rack bar fit perfect.

With the crank shaft pulley finally off I could remove the lower timing belt cover and expose the belt. A pair of scissors made quick work of removing the belt and saved me a few more disassembly steps.

And Removed


The thermostat and water pump were next. The water pump is the weak link of the system and main reason to do the service. Tacoma's have a non-interference belt, meaning that if it breaks the engine won't self destruct, so you could feasibly drive until the belt fails with no repercussions other than a tow truck ride home. The water pump isn't has strong, it usually fails way before the belt causing the engine to overheat and flood the belts and accessories with coolant.

New Water Pump and Thermostat



After the water pump, it was time to install the new belt. I used a special tensioning tool to hold the belt tensioner while I installed the belt. It was a bitch, but after much struggling I got it on with all of the alignment marks lined up with the marks on the cam shafts and crank shaft. This is very important because if one of the cams or crank shaft was one tooth off the engine would self destruct. After the belt was on I turned the engine by hand a complete revolution of the belt to make sure it wasn't slipping. Something peculiar happened, the belt marks were all exactly one tooth to the right of the cam shaft marks. It was consistent on each pulley, but it didn't seem right. Was the belt slipping? After much discussion with Jon of the physics of belts and gears a search on the Internet revealed that this is normal.

Next it was time to put it all back together. I needed the 6 foot breaker bar on the special tool to torque the crank shaft pulley to 217 foot pounds. The order of the belts was particularly confusing, it took several tries to get them on in the right order.

With the engine back together the brake and gear oil changes were next. Most people don't bother changing their brake fluid, but it is important. The BMW club won't let cars on the track without fresh brake fluid each day. This is done in about 20 minutes with a pressurized one man bleeder. It screws on to the reservoir and pressurizes the system so that the old fluid can be bled out of the slave cylinders. Since you don't need someone to pump the brake pedal there is no chance of sucking air into the system or damaging the master cylinder seals. I wanted to adapt the bleeder to do the Tacoma, but unlike European cars it doesn't have a threaded reservoir cap. I improvised an adapter out of an old brake reservoir cap and some hose clamps.

My Improvised Toyota Adapter



When I tested it to see how much pressure it would hold, it seemed to work beautifully. Then at about 10 psi the cap exploded off the reservoir showering me with brake fluid. Luckily, I had covered the cap with a towel so none of the corrosive fluid got on my paint. The reason it exploded was that the hose clamp was too narrow to hold the two-piece cap together. After searching for new cap that would work I decided on the simplest solution, another hose clamp. It worked perfect.

Two Hose Clamps


Bleeding the System


The total cost for everything including special tools and $140 worth of Royal Purple Gear oil was just over $600, which put me $1400 under the dealer. Like all new mechanical projects it took way longer than I thought, but now that I know what I'm doing next time it will go much quicker. Jo and I just got back from a road trip to Taos, NM and the Tacoma purred like a kitten the whole time.

Battle of the Bear

As I mentioned in my previous post Jo and I did support last weekend at the Battle of the Bear mountain bike race. Phoenix Multisport had a good showing and some good results. Doug and Jean-Paul had good races too. It was my first time at a race this year and a reunion of sorts. I had a great time catching up with old friends that I haven't seen since the fall. Even if I can't race right now, it was good to take in the scene and an opportunity to dust off my photography skills. Here are some pics.
