Dear Customer:
RVS has put a lot of research into the remanufacturing process and specification
of our 440 Marine and Industrial Engine.
By initial design this engine was used in the Texas and Oklahoma oil fields
and was operated as a stationary assembly.
Later this assembly was offered to motorhome manufacturers, complete with
transmissions as a power package to be utilized in new production.
FMC motorcoach production chose the 440 M & I engine because of its'
tremendous durability and national warranty. Chrusler made these units available
as certified packages hence certain refinements were made in order that
these engines met the California State smog regulations.
Pursuant to the application in the FMC motorhome the engine packages ran
a little hotter than usual thus we were seeing premature failure of valve
seals etc., along with other components within the engine compartment. (hydrovac
hoses, wiring, etc.)
As time went on we saw this high failure combined with, in our eyes a rather
high oil consumption problem; as Chrusler admitted to us in 1975, that 5-800
miles a quart seemed to be standard.
After analyzing the situation; torque curves, BTU rejection rates, horse
power and general performance, specifications were looked at in order to
improve our overall general picture.
Our affiliation with Chryslers after-market rebuilding process gave us the
opportunity to sit down with the technically minded Chrysler Corporation
infividuals, who can analyze these problems and arrive at responsible solutions.
After interjecting our experience through history, discussions with the
Parnelli Jones organizations and Nasa Ames Research at Moffett Field, California,
we arrived at what we feel is a custom designed specification tailored for
the FMC motorhome. Major changes were made to the lower end in the balancing
process, to arrive at a smoother operating assembly. We increased compression
ratio .8; an advance overstock, and custom tailored a cam and distributer
to provide a much needed boost on the upper end. (provides added passing
ability and hill climbing power.)
Naturally all the critical refinements that Chrysler originally built into
the motor were saved, especially relating to the head and valve configuration.
The end result being a more efficient, smoother operating tuned assembly.
The long block as provided by the Chrysler rebuilding process carries a
six month, 6000 mile nationwide warranty, warrantable with any Dodge or
Chrysler dealer.
RVS supplies additional materials necessary in the engine change, herein
listed and will provide customer support over the phone should service or
technical advise become necessary.
