SOME OUTSTANDING POSTS



DIP STICK REPLACEMENT
Pinkerton


Most of you recall I lost my tranny due to a fluid leak that I missed.  My hatch has a console sitting on it that must be moved before it can be
raised.  This is not conducive to frequent fluid checking.

At the Wisconsin rally I purchased a long shaft tranny tube.  I also took a look at Ken Henderson's.  He uses a 3/8 brake line for the tube to the
front and brazed it into the original tube.  He uses a piece of 1/8" wire rope for the dipstick and both the original and new dipsticks both are in
their tubes and work.  That is, he can use either one.  The newer long wire rope dipstick was 'calibrated' to match the fluid level as show on the
original tube.  Clever guy our Mr. Henderson is.  :d

I had a couple goals:

1- Allow flex between the motor and the hard mount of the long tube.  Manny doesn't like long tubes because as the motor moves, it causes the dipstick
tube to rock in the differential hole and damage the O-ring.  Don't want that to happen....again....  8o :blush:

2- Contrary to what Ken did, I want to be able to add fluid without lifting the hatch.

Ok, here we go.  I'm not saying this is THE way to do this, it might not work well but this time, I've got better temp gauges on the tranny fluid and
a pressure gauge as well so, hopefully, I'll be able to spot any problems before any damage is done.

I fit the original dipstick in place and determined where any branch off had to be to clear the half shaft.  I then bought some 3/4" hard copper tube.
 A piece of steel electrical conduit (EMT) would have worked fine also but I don't like welding galvanized or cleaning the galvanization off so copper
it was.  I cut a fishmouth at the desired angle and the marked where the cutout would be on the original tube.  This was then cut out and the edges
cleaned up.

I used a TIG welder with silicone bronze rod.  I could have just as easily brazed it with a torch or probably a MAPP gas unit or even propane torch
but I've got the TIG so...

To ensure no pinholes weeped, I painted the weld area with epoxy.

The LONG tube was painted and turned around so I could use the bracket to mount it.

This is the modified original tube in place with a NEW O-ring.  :blush:

http://www.gmcmhphotos.com/photos/front-transmission-dipstick/p56610-toranado-long-dipstick.html


Below you can see the new long tube inserted through the congestion of the under hood area and front of the engine.  It is currently BESIDE the new
"Y".

http://www.gmcmhphotos.com/photos/front-transmission-dipstick/p56611-modified-original-dipstick.html


Here is the long tube inside the "Y".  It slips in about an inch and a half.  There is enough 'slop' so that as the engine moves it will allow the
long tube to flex at this joint.  It's mounted hard up front.

http://www.gmcmhphotos.com/photos/front-transmission-dipstick/p56612-the-two-dipsticks-slip-together-the-long-dipstick-is-used-backward.html


And here is the joint with a hose clamped over each end to keep 'stuff' out and fluid in.

http://www.gmcmhphotos.com/photos/front-transmission-dipstick/p56614-some-3-4-hose-and-clamps-keeps-things-leak-free-but-will-allow-the-motor-to.html


On the front end, I cut off the long dipstick.  When I get the transmission fluid level correct, I'll calibrate the new wire rope for the correct
fluid level and weld it to the end of the fancy dipstick.  The business end of the rope is welded solid so it won't catch on anything or unwind.  I'll
do something similar to mark the desired fluid levels.

http://www.gmcmhphotos.com/photos/front-transmission-dipstick/p56613-the-old-bottom-bolts-to-my-electric-windshield-wiper-bracket.html


That's it.  I'm planning on checking my fluid quite frequently.  Changing these transmissions is not much fun. :lol:  :lol:  :lol:

NEW TORSION BARS

PETER HUBER

  a1huber@prodigy.net

 1

I have received quite a few commitments from my GMC friends to purchase the
new Torsion Bar set. However I could not come up to the value of 40 sets as
of today. If any of you are still interested to commit to a set of new,
stronger Torsion bars I might be able to negotiate with the manufacturer a
deal with lower amounts of production for the same price. The price will be
$ 800.00 plus shipping cost.

I had nothing but good satisfactory replies who bought the previous 30 set
of T.Bs.

The present T.B. will be the same as before, stronger by 19% and the hex
will be extended 1" per Ken Henderson's recommendation..

There will be no sales tax, since Jim Hupy will take over and drop ship out
of Oregon.

If you want a set of new Torsion Bars let me know now. Contact me directly
for your commitment on or before October 10, 2014.

I will participate at the GMCWS Fall Rally in Manteca, CA (Oct. 1-6, 2014)
And you can also talk to me regarding the new stronger Torsion Bars.

This will be my the final attempt to round up GMC friends with Torsion Bar
problems.

Greeting to all you great GMCers.
Best regards

MSD's Atomic EFI Receives Distinctive CARB Exemption Status

(AT LEAST ONE GMCer HAS CHECKED)

(AND FOUND THE GMC MOTORHOME

 DOES NOT QUALIFY)




MSD, Atomic EFI
MSD Performance's Atomic Fuel Injection System.


MSD Performance's Atomic Fuel Injection System was granted an Executive Order Number from the California Air Resources Board. The E.O. Number signifies that the Atomic aftermarket EFI system is legal on ’87-and-older GM vehicles in California.
The Atomic EFI system received E.O. Number D-722 which permits the system to be installed in place of the factory carburetor on ’87-and-older GM passenger cars and trucks originally powered by a V8 engine. This Executive Order also means the Atomic EFI system provides "reasonable basis" for satisfying the anti-tampering requirements of the Federal Clean Air Act, thus allowing its use in all other states.
During thorough testing it was confirmed that the Atomic system did not reduce the effectiveness of the applicable vehicle pollution control systems and therefore was granted an exemption from the prohibitions of Section 27156 of the California Vehicle Code for ’87-and-older General Motors passenger cars and pickups originally equipped with a V8 engine and carburetor. MSD will supply an information label with the E.O. Number and details that must be affixed on the vehicle for inspection purposes.


Thanks,

Gary and Joanne Worobec

* measure the starting battery (12.58 volts or so)
* press the boost switch 
* you should hear it click
* voltage measured will change 
  - go down if house battery is low
  - will go up if house charger is on
* you know
  - the boost switch is controlling the boost relay

  - if no change - boost relay is not working
  - 





-------------------------
CHECK YOUR HOUSE CHARGER
* DO YOU HAVE A HOUSE CHARGER
* IS IT A BUZZ BOX
* WHAT IS A  BUZZ BOX
* IS IT CHARGING ALL YOUR BATTERY BANKS
* WHAT VOLTAGE IS IT CHARGING

* #! TURN EVERYTHING OFF- (over night)
* UNPLUG THE GMC ( TURNS OFF THE CHARGER)
*  READ METER - JOT DOWN THE ENGINE BATTERY VOLTAGE
* PUSH THE "BOOST" SWITCH TO READ THE HOUSE AND ENGINE BATTERY VOLTAGE
* PLUG IN THE GMC
* THE VOLTAGE SHOULD CLIMB TO THE "CHARGER VOLTAGE" (about 13.25 volts)
