July 2015 meeting notes and audio

Audio recording of July 2015 meeting available here: http://madhatters4x4.com/blog1/wp-content/uploads/2015/07/July-2015-Meeting.mp3


Highlights from meeting:

  • Trip report from July Lower Fordyce run – the 16 hour ‘day run’ (“The Longest Day” or “The Fordyce Death March”) – in at 9:30am, out at 2am. John & Art highly misjudged the rate of travel with the group and we got to WH2 as the sun was setting. From there to the top of Committee took another 4 hours. Ugh. Mostly minor carnage: Sherry – two tires de-beaded & rocker panel dents. Amber – dented oil pan and shredded front drive shaft boot. Gary – broken front axle.Tony – seized rear locker. Lisa – failed front u-joint by the time she made it home. There was no welding required or any major recovery needed. Ok, Larry needed to be winched off a few tree roots/stump, but its a Bronco thing 🙂
  • Tom isn’t able to make it to Trek to run the raffle – had to go in for emergency surgery for a detached retina.  We got it handled with Dave/Rene/Art/John/Kurt/Terry, etc.
  • Sierra Trek coming up next week. Kurt/Terry, Dave Jones, Rene, etc will be up this Friday/Saturday to tape off our section and set up tents. For folks doing the Thurs run, we have 10 rigs signed up. Plan is to meet at Jones’ cabin Weds nite, grill/bbq dinner there and get a decent nites sleep. For Thurs we will skip staging and head in before the rest of the groups via the Indian Springs entrance. Art is going to do some photography/video  so we need to be out in front to do this.
  • Barrett Lake is open again, so we are going to try to get a weekend in Sept to run it. August looks filled  with other clubs swarming there.
  • Cantina coming up over Labor Day weekend – its a good event to help with the trail.
  • Sept picnic – Deer Valley is still closed. Looks like the plan is going to be to camp at Airport Flats and play on the Rubicon and check out our Adopt-a-Trail section the same weekend.
  • Slick Rock in October is still on. Chris will have final plans for the August meeting.
  • Thanksgiving week trip to the desert – looking at options including Panamint, Calico, Johnson Valley/Stoddard Valley. George inquired about Saline Valley, but the nudity around the hot tubs in Saline might be an issue for folks with kids or weak stomachs.
  • Amber voted in as a member. Welcome Amber!
  • Boner award – where to start with all the ‘fun’ on the July Fordyce run. Nominees: Larry for having his Bronco almost flopped by some tree roots (and roots that even Sherry was able to clear :-), Art&John for really bad trail time planning for the Fordyce run, and Amber for her balancing on a boulder on the WH1 bypass. Larry won it by one vote!
  • Easter Jeep Safari next March – the campground that John & Rene wanted to go back to starts taking reservations Aug 1. Rene will send mail out with the details.
  • Voted on proposal by Art to have the club cover group camping fees for events, including club runs (like Trek and the Chalet rental @ Loon Lake for the Rubicon run), work parties where we have to pay for group camping. It would not cover Larry’s hotel costs or individual camping fees like at Cisco Grove. Motion passed. Treasurer will manage the budgeting of this annually and raise any issues if they come up, but we won’t keep voting on these individual expenditures any longer.
  • Dennis mentioned whether we wanted to try to host a club hospitality room at Convention next year. Cal4 apparently had issues with clubs serving alcohol and that won’t be happening again, so not clear whether we’d get people in the room without booze. In any case, it appears the host hotel is out of suite rooms anyway.

Definitive answer on ARB pressure

from an email by Dennis.
——– ——– ——– ——–

I thought some of you might like to know this.

Here’s a good link to how to rebuild an ARB locker.  The problems they found are exactly what I found in mine.  Parts are on order.

I sent a query to ARB Tech (see below).  I had heard different stories about what pressure range to use with the locker, compared with the instructions I had from 2007.  So their guy gave me an answer I like:

Hey Dennis,

When installing a new bonded seal or O-rings I coat them with gear oil (80/90w).
The pressure for locker activation is good between 85 and 150 psi. For years it was 70-100 but we have found through competition use that they are good up to 150psi. Beyond that the solenoid will start to leak off at about 170-180psi. The higher pressure gives a better “punch” to the clutch gear for engagement and stronger pressure to stay engaged.

Hope this helps

——– Forwarded Message ——–


I find myself rebuilding an RD116 in my Jeep after 8 years of pretty easy usage.  But I have a couple of questions:

1)  What lubricant should I use on the new bonded seal?

2)  The installation instructions (that I saved!) say that the minimum air pressure is 85 psi and the maximum is 105 psi.  But I have found more than one website that says they should use no less than 100 psi, but are OK up to 150 psi.  Can you enlighten me about this?  I have Kilby onboard air that cycles from 140 psi to 120 psi, and have had two regulators fail that were set to 95 psi, so would like to eliminate the regulator.

Thanks, Dennis

Rubicon 2015

Hi Gang,
For those of us that went up Thursday we were greeted with thunder & lightning downpours and an inch of hail. We had no problem getting up on time in the morning after listening to Scott’s snoring all night. By 7am we had 18 rigs all aired down and ready to go ,including a couple from Canada. They found us on facebook . Thanks again for being ready on time. Things were going well until I went up the steps on the other side of the bowl and ripped a motor mount. John and his dad welded straps to fix it. Meanwhile Tom & DD took over to keep the club rolling. Thanks guys! After a loose bolt stop we caught the main group by Ellis. By the time we got to little sluice John developed a leaky hose. A small group waited for John, the others continued with Tom & DD to camp .That was the last we saw of the main group. We all got stuck a little but only Canada needed the wench and straps. We got to the Springs about 4:30 got camp set up without getting wet. The storm was there it just went around us. We had a nice relaxing Saturday. Scott caught a fish. I caught a couple dozen crawdads and a trout. In the afternoon we had a lot of lightning and it poured at dark. John & Tom lead 14 rigs at 7am, I heard Chris got stuck in the mud. The rest of us left at 9:20 moving at a record pace. We caught the main group at Tahoma staging around noon. We had no damage except Canada loss a piece of fender on V rock. We had a great run with 18 rigs and very little problems.

Access alert from Cal4wheel – West Mojave Plan

Deadline is June 4, 2015

The West Mojave Route Management Plan is open for public comments through June 4, 2015. The BLM is proposing to add about 4,500 miles of roads to the legal road network for motorized vehicle travel. The OHV community needs to support this by making positive comments to add the roads to the system as opposed to closing them permanently. The link to the website is below:

set screw: Stainless steel 316 vs. Alloy steel black oil finish

I need to replace a pair of temporary bolts added during last weekend’s emergency mechanical fix with proper set screws.  The set screws are used inside the engine bay to adjust the position of the York air compressor on its mounting plate.  The serpentine belt has no tensioner so shifting the air compressor is the way I have to tension the belt.  I have found set screws online in 2 forms:  “Stainless steel 316” and “Alloy steel black oil finish“.  Should I use stainless steel here or is alloy steel acceptable/preferable?  The stainless set screws are 3 times the price, but the overall price difference of $6 makes price not a factor to me for this job.
