Has anyone converted their 455 to a serpentine belt drive? With all of the issues with V-belt fitment and tensioning I am considering the option.
Thanks!

Lee Harrison did oe, and it was not very successful as he put the tensioner
on the wrong side.
We have had few we removed off customers coach we dumped in recycle bins.
My feeling is that it would be better to keep the v belt as I have not seen
that much problems.
I believe Gary Kosier knows how to do one that works.

Yes, I built a "thrifty boy" serpentine for the Olds, using brackets off a
Chevy truck using a modern CS130D alternator and a Sanden
AC compressor. No on showed any interest, so I just left it lay.

Gary,
What would the advantage be?
What does it cost?
How is it working for you?

Gary,
I know that many want to know what you did, how you did it and what parts did you use. I know that you have pictures out there and I will post the link in this Email. Everyone will need to read the explanations under the pictures.

Well, first would be that the serpentine is the modern design. The belt
manufacturers
have mostly converted to metric sizes. And they're not replacing an
equipment as the
V-belt is being phased out. Quality is in the toilet with some brands.
Second, using solid, cast aluminum brackets eliminates that cobbled up mess
of of
brackets, braces, spacers and various hootises that Olds used to attach the
accessories.
And, of course, using a modern alternator and AC compressor is an
advantage.
I forgot to mention that the serpentine belt is always correctly adjusted.
Costwise, It's hard to remember. I got the big brackets and alternator at
the junkyard.
The worst part was Chevy had a brain fart on their design. They put a
mounting bolt
behind the PS pump reservoir. You have to remove the pump to get to it. To
remove
The pump mounting bolts, you have to remove the pressed on pulley.(in the
yard)
I later found another pump with an offset reservoir that gives access to the
bolt.
And I put a hole in the pulley that gives access to the pump mounting bolts.
The Chevy brackets are made for the R4 round AC compressor, but the Sanden
will
fit the same holes. I made brackets to offset the Sanden upwards to clear
the valve cover.
I got the Olds reverse rotation water pump at the deep discount. All of the
head scratching
and measuring and labor were free, of course.
Oh, I forgot, walking out in the yard, I passed a Dodge truck with the nose
off. Realizing
that I needed a long belt for measuring I clipped it and removed it. The
crank pulley
looked handy, so I took it also. Lucky me, it turned out to have the
correct offset for
my needs after redrilling the bolt holes.
How's it working out for me? I took this on as a challenge to see if I
could make it work.
After I did, no one was interested and since I use a Cadillac, it's just
laying there.
Sorry about the long explanation, but that's the way I am.

John,

Kinda' embarrassing, but those pictures are of the Cadillac conversion.
I've got a write up and pictures somewhere, but since there was
ZERO interest in the project, I just tucked it away somewhere.

I was thinking of this http://marchperformance.com/oldsmobile/oldsmobile-455/all-inclusive-kits.html . Fully engineered, equipped with a modern A/C
compressor. It's spendy but I am going to be driving this coach at least 25 years (If I don't kick it first) and I really hate screwing with the
constant adjustment and PITA belt changes of the stock setup.

At one time Jim Bounds said he was negotiating with March for a GMCMH
version without all the "bling". I've heard nothing more for many months;
you might check with him.

Beyond that, after having developed a very satisfactory, inexpensive, dual
serpentine system for my Cad500, I'm convinced that a similar system can be
fitted to the 455. I haven't seen Gary's setup so I can't comment on it.
If I still had a 455 on the floor, I'd be studying it, but I don't have.

My Cad took a couple of days of sitting & pondering, but eventually it all
worked out with only a little machining and welding. It doesn't require a
reverse flow water pump and includes a Sanden A/C compressor and CS-130D
alternator.

I should note that I ran a single serpentine belt (JR Slaten & Bobby Moore
design) for several years before installing the Cad 500, so I'm a firm
believer in them.

Before you get real excited about that March serpentine, think about trying
to hit the crank pulley with a timing light.
It's difficult enough with a stocker, but impossible with that concoction.

The coach has crank triggered ignition and the timing is set on the laptop. I would like a more OEM pulley style setup as appearance is not important
and it would be a heck of a lot cheaper, that's why I asked if anyone had tried it. I figured with all the issues V-belts cause, someone else might
have already solved the issue (don't reinvent the wheel etc etc). I figured this would make a good winter project.

I've decided to add "hootis" to my vocabulary. So much more elegant than
putter-onner. And it captures the sheer insanity of all the random bits of
mutually interlocking puzzle pieces that attach the power steering bracket.

I never considered a serpentine setup, because each of the 4,576 times I've
had to mess with the belts on my coach, I was convinced it was the last.

The coach has an electromotive Tec2 fuel injection and ignition system. They make an ignition control only box as well, uses a 60-2 crank trigger
wheel. My system runs great but is no longer supported. I am considering my replacement options while it still runs great. This is there ignition

Interesting! Those coils are the GM Waste Coils as used on a bunch of
vehicles. My concoction is based on the ignition control module
with those coils as used on the 93-99 Cadillac Northstar. Since that motor
becomes an unserviceable lump at about 100k miles, the
modules become readily available in the men's mall. It does require a GM
ECM to provide an advance protocol. Obviously, the EBL
conversion normally used in the GMC conversion to EFI. I should add that
one of my sources has it working with MegaSquirt EFI.
I am going to try to have a show-and-tell display at Elkhart if you're going
to be there.

I wish I could go but we can't make it this year. I have been looking at the MegaSquirt, Halltech and even the Fitech port injection. I hate the idea
of going backwards to a throttle body setup. The coach runs great as is but if the ECU takes a dump I will be dead in the water without a replacement.
I like the fact the coils are readily available and the tuning is flexible but frankly electromotive lost some key people and their tech support is
lacking. If I get a newer version of their ECU I can just load up my Bin file and go. I am really looking at all possible options to keep port
injection and run a modern ECU.

If you already have a port injection manifold, I would recommend sticking to
all GM parts, where possible. The advantages are good quality,
ready supply of parts both new and used, cheap prices, and terrific support
from the GMCMH-EFI group. The EBL P4 conversion from
Dynamic EFI gives easy adjustability to your individual combination. And,
of course, it will support my concoction of distributorless ignition.
GM is going to be around for a long time and there is a wealth of
documentation on all their stuff.
More to come!

Trevor,
Bobby was a very creative person and had many different projects on his coach each year. First met him in 1999 and the Myrtle Beach GMCMI spring convention.

It's my understanding that Bobby and JR Slaten developed that serpentine
system together. Bobby gave me the 3rd set they made. There seem to be
some differences between Trevor's set and mine, but then I made some
changes myself so they may have been identical earlier. That engine and
belts are on the engine in my son's coach, so one day maybe I'll get a
chance to make photos of it to post. I must say that it's performed
flawlessly for maybe 70,000 miles, even running the OEM-style Water Pump
backward.

I did have some WP problems not long before I installed the Cad 500, but
they were all occurred while I was testing protypes of Leigh Harrison's
reverse flow design. The final version of that is still hanging on my
storeroom wall, unused. That was before the 350 diesel reverse flow pump
was discovered. When the last prototype failed on me, I installed an Auto
Zone severe duty pump, without even improving the flow pattern as I'd done
previously. My son's probably put 15-20,000 SE USA miles on that with no
overheating problems.

I still think a simpler system, using two serpentine belts, can be made for
very little cost -- I haven't yet seen Gary K's version.

i am discovering how creative bobby moore was there are lots of little extras. when i first got the coach i noticed how all the slots in the screws
are in vertical alignment as well as the crosses in the phillip head screws are all in the same orientation . this indicates to me how much thought he
put into everything

Trevor,

How 'bout that electric parking brake? Previously an electric seat
adjuster, IIRC. :-)

Bobby was the very first GMCer we met in '98. We attended our first GMC
rally at Lake Lanier Islands, GA in our 40' diesel pusher before getting
the GMC road-ready. We were parked well away from the GMC's and
encountered the Moore's enroute to the "rest of the crowd". It took a
couple of hours to get to the "rest of the crowd". Our friendship grew
continuously from then until he passed away; I learned a LOT from him.

unfortunately ken that parking brake was no longer in operation when i got the coach it had standard calipers on the rear wheels and all the parking
brake cable was gone the seat adjuster is still there . this is one of my problems as to register here i need a working park brake i am in the process
of converting the rear wheel set back to drums and Rob . M has brought a handbrake lever and front cable back from the states

Trevor,

You may want to consider keeping the seat adjuster to pull the parking
brake cable. That setup was a lot more effective than the hand lever when
Bobby had it working. I'm sure there are photos somewhere of that, or a
similar, setup if you can't figure out how it worked. That's assuming the
law down there only cares if it works, not how.
