•
The Dodge Ram 3500/4500/5500 Chassis cab models equipped with diesel engines that have the
PTO prep option (LBN) have the capability of mounting and controlling a PTO.
•
The gasoline powered models do not have PTO capability.
•
The Aisin AS68RC Automatic transmission can use devices up to 35 HP and 130 ft‐lbs torque.
Chelsea 270 or 252 series fit this transmission. Muncie CS6 series fit this transmission. There is
no difference in how PTO and pump mount between 4x2 and 4x4 automatic models.
•
The G56 manual transmissions are limited in power output only by the PTO manufacturers'
maximums. Chelsea 442 (deep mount) series fit this transmission, however on 4x4 models this
PTO is very close to the front driveshaft . Muncie Alpha series fits this transmission.
•
The automatic transmission models have been test fit with 17 GPM rated size single pumps and
tandem 11 GPM rated pumps. While these larger pumps have limited clearance to the exhaust
system and many people have mentioned this as a concern, it should be noted that the exhaust
pipe in the PTO area is a double walled pipe which provides significant heat insulation
properties. In fact, in our extreme heat PTO testing in over 100 degree F Fahrenheit
temperature we never exceeded 200 degree F on the PTO, pump or hoses.
•
The manual transmission models are as follows: The 4x2 models have no particular packaging
limitations with respect to direct mount pumps. The 4x4 models are limited by the location of
the front driveshaft to approximately a standard 11 GPM rated pump (although larger pumps
may have been successfully fitted in the field). However, some customers have had success
using bent axis piston pumps (mounted forward) to get substantially higher flows.
•
If you have specific PTO and pump fitment questions and can provide the actual PTO and pump
combination, we can test fit it and provide pictures and instructions on how to install your
specific combination.
Please read this information carefully and call us with any questions before you order a vehicle so you
understand the specific capabilities of our PTO system.
•
The Automatic transmission PTO is turbine driven not engine driven. What this means is that
the PTO will work only with the stationary mode in park, or in mobile mode with the vehicle
moving at approximately 7 mph and above or in neutral. Because of this the PTO system is not a
suitable system for vehicles like: snow plows, autoloader wreckers, or dump trucks if they are
used to dump and spread at a crawling speed. These vehicles are more effective with an
engine driven 'clutch pump' type hydraulic pump. Alternatively, Parker‐Chelsea makes a
product called Stored Energy Management System (SEMS) that allows such applications to
function.
•
The size and package space do not allow for components driven by a driveshaft from a PTO on
our trucks. The automatic transmission models have exhaust system components in the way
that cannot be relocated because it will effect emissions compliance. The manual transmission
models have either the transfer case (4x4) or the transmission crossmember in the way.
•
The manual transmission has the capability to support a split shaft PTO. The automatic
transmission model does not support a split shaft PTO because the transmission cannot be held
in direct drive gear.
