Chelsea P.T.O. Model Numbering System

Chelsea P.T.O. Model
Numbering System
Objectives
• To acquaint users with the Chelsea model numbering system
• To make users aware of the different models and options that are available with Chelsea P.T.O.s
Features of the Numbering System
• Constant 13 digits for all models
• Each digit represents a particular option
• Consistent from model to model
Features of the Numbering System
Examples
442XQAHX-W3XD
The first 3 digits represent the model number.
• 442, 447, 489 & 880 Series are examples of mechanical shift model numbers
• 230/231, 270/271 and 277/278 Series are examples of Powershift models
• 941 Series is an example of a split shaft model
• 626/645 Series are examples of geared adapters
• CAT-D and 541 Series are examples of rear mounts
Features of the Numbering System
Examples – Mechanical Shift
442XQAHX-W3XD
• The 4th digit signifies the case style
• There are 5 possible case options for mechanically
shifted P.T.O.s
- X signifies the standard housing for the 442 and
447 models
- Z signifies the deep mount housing for the 442
and 447
- G signifies the standard housing w/ metric stud kit
for the 442, 447, and 489 models
- K stands for a standard housing less the stud kit
- L means deep mount housing less the stud kit
Features of the Numbering System
Examples – Mechanical Shift
442XQAHX-W3XD
• The 5th digit signifies the Speed Ratio of the P.T.O.
• The closer to the end of the alphabet the 5th digit is, the FASTER the P.T.O. output shaft will turn
• For specific speeds, consult the Chelsea HY25-3000/US Applications catalog
442XQAHX-W3XD
• The 6th and 7th digits are the input gear designators
• These digits are the key that will tell you if a particular input gear will mesh with the driver gear in a
specific transmission
NOTE: The General Information section in the HY25-3000/US catalog contains a breakdown of all the 2
digit gear designators. This breakdown includes info on Make(s) of transmission each designator is
typically found on.
Features of the Numbering System
Examples – Mechanical Shift
442XQAHX-W3XD
• The 8th digit calls out the lubrication option
- This digit can only be either an X (standard) or a P (pressure lube)
- Pressure lubrication must be specified whenever the P.T.O. aperture is higher than the oil level of
the transmission
• All Allison transmissions have the P.T.O. aperture above the oil level of the transmission
• Therefore the pressure lubrication option is required for any P.T.O. that is going to be installed on
an Allison
442XQAHX-W3XD
• The 9th digit is a dash and must be present
Features of the Numbering System
Examples – Mechanical Shift
442XQAHX-W3XD
• The 10th digit signifies the type of shifter that is mounted on this P.T.O.
• The most popular shifter is wire, signified by the letter W
• Other shifter types are:
- A = Air
- V = Air less installation
- W = Cable shift
- M = Constant mesh
- P = Electric over air (12 volt)
Features of the Numbering System
Examples – Mechanical Shift
-
Q = Electric over air (24 volt)
H = No shifter cover
X = Wire (less cable and knob)
S = P.T.O./Dump Pump combo valve
T = P.T.O. & Combo Valve less kick out & neutral return
Features of the Numbering System
Examples – Mechanical Shift
442XQAHX-W3XD
• The 11th digit signifies the assembly arrangement, or the relative positions of the P.T.O. input gear and
output shaft when the P.T.O. is mounted on the transmission and the P.T.O. is engaged
• Which assembly arrangement you need is determined by:
- Where the P.T.O. driver gear is located - towards the front or towards the rear of the transmission
- Which way the P.T.O. output shaft must point - to the front or rear of the vehicle
• The 3 assembly arrangement is the most commonly used
• When a different arrangement is called for, it’s possible to change any arrangement into any other in
just a few minutes by changing the positions of the internal components
Features of the Numbering System
Examples – Mechanical Shift
442XQAHX-W3XD

Features of the Numbering System
Examples – 890 Family
• The 890 family of Power Take-Offs (P.T.O.) all
install in the same manner to the transmission.
The main difference will be the mounting plate
that is used to attach the P.T.O. output section to
the rear of the transmission case. Refer to the
chart below for P.T.O. Series and Mounting
Codes for information on your P.T.O.
• Several important things to remember
- Mounting Options (Brackets) are Unique to
Transmissions
- Output Flanges are Dependent on mounting
location of P.T.O. and transmission model
