Serpentine?
- Thread starter Jim Hupy
- Start date
Jim,
For several years, until I installed the Cad500 (with serpentine), I ran a
very reliable serpentine designed and built by JR Slaten and Bobby Moore.
IIRC, they made 3 sets and I wound up with #3. I did make a couple of
changes to it, but it never gave me a moment's trouble. For most of the
miles, I ran a standard water pump, slightly modified to improve water
flow. I never had any overheating. Toward the end of my use of it, I ran
prototype tests for Leigh Harrison on the reverse flow pump he designed
before he discovered the diesel pump.
Currently, the only one I know working with 403/455 serpentines is Gary
Kosier, and I think his is a hybrid with V and Serpentine belts.
I don't have decent photos of the system, but I do have a few parts left
around here. Fact is, if memory serves at all, I still have the whole
thing somewhere since I sold the engine without it. I'll try to put them
all into a decent pile and make photos of that -- in a few days. Hmmm... I
KNOW I've got Leigh's last water pump version hanging on the wall, un-used,
since it arrived after I decided on the Cad 500.
Let me know if you're interested -- despite the shipping distance. You
could just come here and install it -- you DO owe me a visit, you know.
The trip home would be a good test drive.

I believe (hope) Tom Pryor is working on one minus the AC compressor.

Ken,
Last year I obtained all the bits and pieces of both JR / Bobby's system as well as Gary's. When I get a few projects done down here
in Texas I'll take a look at what I've got and figger out how I'll approach making the system.

the only cons I can think of would be the extra weight of the bracketry and the complications it might add to servicing and maintenance of it and
everything near it.
judging by GMs examples, it has to be substantial. some of them are massive one piece, cast iron deals and make it a huge PITA to get to some
components for R&R, the whole thing has to come off sometimes for what would have been a simple deal without it and, as substantial as they are (The
OEM ones) Ive seen one that was broken but I think that was probably due to a previous botched job of something or another by an incompetent monkey.
I wouldnt want to try it unless the v-belts were very problematic.

Again, I see it as an exercise. The ones I've seen work. I'm not up for the time to install. Pryor is in the process of doing one on his coach, I
believe he actually manufactured one or two of the pulleys.

Gene, in my case, I have a 403 with a/c, and I have upgraded my alternator
to 100 amps. I started out with a single pulley driving the alternator, and
the belt squealed, particularly on startup. So I upgraded to tandem belts
with a two belt pulley on the alternator. If you tighten the belts enough,
the squeal is minimized, but still is present at times. Subsequently, belt
life is short. When a belt fails, it frequently takes out stuff like vacuum
lines, wire harness, radiator and heater and a/c hoses and related
fittings.
On the road belt failures are NEVER ANY FUN, and I have had enough of
them to motivate me to seek a more reliable, longer lasting setup.
I guess that is why in my case. Others may have their own reasons.

I am surprised that someone would want to go serpentine. Great that we have iotions.
I also do not understand the bigger alternator in todays world. I just think in today's LED world,
It is easier to set your coach up to be more energy effecient then to find a way to produce more amps. Just seems more amps means more wear and less
life on components.
I have a rebuilt stock alternator, and have never felt a need for any more amps.
See many who have the 100 amp with no problems on a single pully, yet others cant keep a belt. Strange.

I suspect that the belt squealing on startup has to do with the load on the alternator during startup. I had a similar problem with a service vehicle that had a two way radio connected directly to the battery (As suggested by the radio manufacturer). With the radio on, belt squeal, radio off, no squeal.

One answer. Extended dry camping. I live at the 45th parallel, in Oregon,
where the sky is cloudy a great deal of the time, so solar is less
effective here. I still run the 6K onan in my coach. I have changed all the
incandescent bulbs in the coach out to LED. Hard to run Judy's Coffee maker
on solar, though. That baby uses 1500 watts.
Have you ever heard the expression "A happy wife is a happy life!"? It
applies here. We use our coach year round here, and use the furnace in the
winter. It is also a high amp draw device that is hard to operate on solar,
so, it takes good batteries to run all night.
Some people do not like the generators running, and I don't blame
them. So, the best backup for that is a larger engine alternator that will
replenish the batteries more efficiently.
This is what works for us. Your needs might be far different from ours.

Well Johnny B is right, I have been spending entirely too much time on this
Serpentine Modification and not enough time on making my coach ready for
movement!
My approach:
- Make a serpentine system that uses NO new brackets, NO opposite
rotation water pump, and uses current off the shelf pulley components.
- At this stage it is a 455 only modification and does not encompass the
AC drive......it will remain a V belt. (The 403 has an UN-friendly
construction and different offset)
- With appropriate fixtures and tooling remove two of the v-pulley
segments from our OEM water pump and crank pulleys known as the Under
drive pulley.
- recondition the drive face of the each of the OEM donor pulleys.
- Reassemble an off the shelf serpentine segment pulley to the Donor OEM
pulley and achieve less than .010" run out in any direction.
- Work with a known serpentine pulley manufacturer, identify a
alternator pulley size to optimize output for our RPM range. (650rpm idle
/ 3600 max)
I believe that next week (WE 7/20) I can have all the details and images
ready for the tribe to comment on.
FYI, In Sept. I can have two sets ready for install. That means you send
me your OEM pulleys for inspection and measurement. If they meet my
requirements for modification, I will send you set of pulleys with run out
values in both radial and axial positions for the serpentine pulley
segment. You will also receive instructions and parts to purchase, ie,
Power steering Pulley, alternator pulley and belt size, and a strait edge
for pulley alignment.
ONCE YOU START PUTTING A STRAIT EDGE ON YOUR PULLEYS YOU WILL BE AMAZED AT
PULLEY MISALIGNMENT OPPORTUNITIES THAT YOU WILL ENCOUNTER, EVEN WITH THE
V-BELT SYSTEM, JUST SAY'N.

I would be interested in being a system tester. I have a 1975 Eleganza II with a 455 in it.

Hupy, do you know the corrolary to the Happy Wife: 'If Mama ain't happy, ain't NObody happy."
Someone needs to investigate where the A/C compressor might be relocated so it could be spun off a single serpentine belt along with the rest of the
accessories.

Probably due to the brand of the belt and the tension.
I have had a 100 amp alternator for over 20 years and I don’t have an squeal or belt life problem and I have the single groove pulley on the alternator.
Someone with that problem should probably try an industrial belt. They are available in the sizes we need and are a much stronger and better gripping belt. I have not had to use them but I know some that have and they are very happy with them.
