Vintage RV & Motorhome restorations - "The GMC Coop"

The Co-op: Trying to get an early start…….

There’s just not enough time in a day to do all the things around here, yesterday went wayyyyy to fast!

The pic of “Larry” yesterday was picking up some long sections of trim.  With the rear door, we can transport 24′ sticks of trim!  Larry runs so good its a pleasure to pick up parts……one of my jobs.  Paints starting to age out but the flames keep Larry look fun.

There’s a good reason Jason is seated in the engine compartmenta’ll this stuff came out with none of it going back inbroken down to the loose timing chain, the rebuild is getting an all new serpentine belt system, no fan, superfat off shelf (not custom) radiator with a double fan box.  Stay tuned and follow this project.

.The 72 Revcon gets final instruction for launch today.  A year and half work, it was worth the hassles

Most of you have heard @ the concave intake manifold and the need to block off the exhaust crossover thru the intake.  Here’s a classic pic to show the issue.   This motor was cleaned and repainted (Krylon rebuild) and the first time it was driven its obvious that hot exhaust is still burning the motor.Git’s really, after 45 years of heavy heat cycles, if your crossovers are not blocked off, this heat evidence thru the middle of the intake MUST convince you! Come on guys, do this.

Another issue many are having trouble with is fuel blowing out of the filler.  There were several comebacks on the thread but the real problem was never discussed.  Our 2 4.5″ deep, 25 gallon steel fuel tanks vent thru a 20′ single 5/16″ vent line running from the vapor separator in the driver rear wheel well all the way forward to the vapor canister under the driver seat.  Can you say …not enough vent?  The tanks then pressurized and pulling off the fuel cap releases the air and fuel out the filler neck.  We add a second vapor separator which adds additional venting to let out the tank pressure while in use.  2 vapor separators guys, if you want to know more give me a call.These flat bottom steel tanks are a serious weak point in our classic coach, fix it!

One big challenge for me in this new video platform networking is the time to produce then download it all.  Late last week we did a definitive video on the 1 wire alternator upgrade.  Our first video was flawed……….a comment was made “hard to back out of internet information.”  Guys, you all aren’t Lemmings are you?  Don’t just do a thing cause other people do it and certainly don’t follow folks who try making themselves look bigger by making others look little!  There MUST be room in this group to discuss things to make them better.  Mistakes need to be made and updated if needed….that’s how things get better!……everyone makes errors.  For the time being, here is the grease board prop I used to explain the wiring mod in the video to accept this updated , stronger alternator.  Stay tuned for the video when it finally gets put together, refer to this pic.  There is also an update being put into the next “Vintage RVing publication.  Please call me if you need input right now.You can use 1 of many combiner/isolator units available.  We use the Samlex ACR-160.  Its solid state, pulls 1.8ma on standby (almost nothing) with 160amp continuous rating with a 480amp peak.  A very nice unit, look it up.  We have them for $125.  Lemme know if you’re interested.

Ok, so I got a little plunked out, fewwwww.  Now its off to the shop for another big day.  Call if I can help you, thanks for your support and remember, Motorhome Rehab Ranch on Patreon.com is making videos, get involved……see ya later

Hey, does YOUR painter have a tat of a spray gun on his arm?  Mine does!…….
