Title: 15+ yrs of sitting..and the Coach made it home :)
Post by: Gerry4104 on March 30, 2012, 07:03:08 AM
She ran smooth as silk..shifted flawlessly ( up and down) shifter assy is nice and tight...clutched perfect...nearly every light worked minus a couple clearance lights..

I have yet to see this engine, blow any smoke....

all the guages worked althought the speedo is off a bit.and the tach is a bit all over the place at times...

all the dash lights work   :)

the brakes worked great...

the rear airbags wouldnt air up, and the valve was seeping some air...

it pulls like a monster to the right, it wants to put you in the wheat, but it was managable..

pulled some big hills without downshifting or lugging the motor...

ran perfect temp at idle an in use..was charging fine right in the 14 range while going down the road...air cycled between 90-1120 while going down the road as well even with the suspension valve seeping air....oil pressure between 40-50 going down the road..about 20 + at idle hot...

Power steering was dry but filled it and so far no leaks and works very well...

trip home was about 60 miles and it made it !  without a hickup

Tires are square and boy can you feel it..

no leaks upon arrival home either..  so far so good....

havent tried reverse yet but later today i will know about that...

now the work begins...soda blasting the bus..PM'ing everything..getting the front end checked out and an allignment..all new wheels an tires..simulators...paint and then on to the interior for a massive updating...

and thanks to everyone that chimed in on my posts here...you guys were a big help !

Gerry

Glad that it made it OK.. I once helped one of my friends start a truck with an 8v71 in it that hadn't ran for that long... and it ran on the old fuel after we changed the filters and used ether... I was really suprised..
Now you have all the normal billion things that have to be attended to... ;D

That's the great thing about Diesels-they can "sleep" for years and just be restarted like it was yesterday they ran.  I have a 6kw air cooled Onan Diesel genset (really loud) that I had in storage for 7 years.  It fired up like it had ran yesterday.  Unlike gasoline that usually have to replace the carb and other fuel system since gasoline mucks up after a few weeks.  Good Luck, TomC

Very Cool Gerry!

We have a 1960 '04 and love it. Enjoy bringing her back to life. Sounds like you got a good one! ;)

Thanks Kev...I'm hard at work already.....  tried reverse gear today, and what do ya know, it worked like a charm....so far so good on the mechanicals....

Started the steam pressure washing today...and the soda blasting will be following here pretty quick....

pulling all the glass and then painting...Champagne top, black in the window area. and Champagne down to cargo bays....

everything below that, polished aluminum to a mirror finish....

then on to the interior..ugh..that will take a bit....

but looking forward to it all....eta 8 weeks from now done !  we will see....  :)

Good to hear. Bought my 91 Prevost Conversion last summer same scenario. Stored 10 years with Fella passing bought from wife. 52,000 on silver Series 8V-92, 5 speed. Installed new Batteries. Had A few issues with ac charge (cruiseairs), frige (installed new one) replaced out dated satellite  system and no problems with drivetrain or engine. Mine was stored in a climate controlled bus barn it's entire life which helped,they say. Texas Custom Coach out of Pipe Creek Texas ran all the systems for checkout and installs. Good Luck on the bus and Happy Motoring.

On the pulling to the right...

Worn suspension parts in the rear can do that, as well as a front alignment problem.

You need a shop that knows about buses, a truck place will declare the front fine and money will have been wasted.

happy coaching!

In the rear suspension area ..what should i be looking at for the usual suspects....

the tires are total crap, and i thought that might have had alot to do with it as well...

the gentleman i got it from is 81 and has no reason to lie, and he said the bus went striaght down the road..always.... but after sitting 15+ anything could be going on now...LOL  :)

I will be checking out everything, but a  bit of guidance would be greatly appreciated...thanks Gerry

Radius rods are frequent suspects, they locate the axle assembly. The rubber donuts in the ends wear out and let the axle move in relation to the body.

Inspect the entire axle assembly for broken or missing fasteners that might allow the axle to move in relation to its proper mounting position.

And as you noted, start with fresh tires, and see if anything changes before messing with things that might not need messing with.

The heart breaker is if you have bulkhead failure, allowing the coach to go banana shaped. Look carefully down the line of both sides, there should be absolutely no curve in or out of the body. Not the end of the world, depending on what has failed. But a lot of work for a busnut.

happy coaching!

First thing i would do is get new tires and see how it drives,.......no sense in spending money on suspension parts first.

Ditto on the tires. Mine were 10 years old (michelins) with 200 miles on them but didn't trust them. I know tires will make a big difference with these heavy coaches.

Roy, the guy i got it from said the bulkhead has been done already..he made a point of mentioning that...so hopefully that is all good to go....

Before putting new tires "I" would take a long hard look (at least a visual inspection) at all rubber bushings, parts, links, etc to make sure they are at least decent. Tires develop wear patterns real fast, you know....

Before you spend a dime on tires, run the coach over a commercial truck scale to find out how much weight you're carrying on each axle.  Divide that number by the number of tires on the axle to get the average weight being carried by each tire.  Add 200 lbs to this number as a "fudge factor" for "stuff." 

Now go to the tire manufacturer's website and find the tire inflation load charts based on your tire size.  Find the pressure that most closely matches the weight you arrived at earlier, and inflate the tires to that psi.  (I personally round UP to the next 5 psi.)

After readjusting the tire pressures properly, take the coach out for another run and see if maybe, just maybe, that was the problem.

Started the steam pressure washing today...and the soda blasting will be following here pretty quick....
Be aware that the soda blasting WILL mar the anodized finish of the aluminum.  I had that done to my 4106 after it got "tagged" in the temporary storage lot.  After that, you could still see the "tags" in the aluminum, even tho the paint was gone.  Only way to remove was to paint it.  And yes, the guy (a colleague) knew what he was doing - he's been blasting for over 20 years - he used the smallest, finest grain soda available for the job.

FYI, polishing the aluminum siding on a GMC has been cussed/discussed on the two big bus bulletin boards numerous times over the years.  Cliff's Notes version: It's a lot more complicated than polishing the stainless on an MCI, plus requires constant repolishing, because of oxidation.  Do a google search on this BBS, plus the Archives over at BNO (www.busnut.com (http://www.busnut.com)) for more info.

So all it took was "knowing the secret," eh?  That's good!

Finally, speaking of tires:

If you're going to be in the market for new, be aware that GM designed the powertrain around tires that turned 495 revs per mile.  So, when shopping, try to find replacements that come as close as possible to the original, for OEM performance.  You can use 22.5 or 24.5 inch rims, that doesn't really matter - it's the tire revs per mile that's the important number.  22.5s are the most popular, btw.

Tires that turn LESS than 495 will give you slightly better fuel mileage, tires that turn MORE than 495 will have the opposite effect.

The HD truck tire market is currently in the middle of converting over to metric sizing, similar to what our autos have used for a decade now.  Thus a 315/80R22.5 is roughly the equivalent of a 12R22.5, an 11R22.5 crosses over to about a 295/75R22.5.  But again, pay attention to the tire revs per mile number while you shop!  (Plus load range, based on the weight you're carrying.)

FWIW & HTH. . .

Well since he said that the tires are "total crap" and need to be replaced anyway, that would be the first thing i would do.....driving it afterwards for a mile or two should tell if it makes a difference or not and should not cause a lot of wear.  Then i would be looking at the suspension to see what kind of shape it is in. :)
