HYDRAULIC TORQUE CONVERTERS
To meet the requirements of diesel installations from 30 to 3500 hp, Twin Disc offers
a complete line of Single-Stage Hydraulic Torque converters of both the stationary
and rotating housing type and Three-Stage Hydraulic Torque converters in a wide
range of types, sizes and capacities with a broad variety of input and output combinations.
Twin Disc torque converters minimize engine lugging and stalling, permit engines
to operate within their most efficient speed range, producing rated horsepower regardless
of load demand. By transmitting torque entirely through fluid mass in motion, mechanical
connection is eliminated. Twin Disc torque converters minimize or eliminate entirely
the need for shifting, clutching or declutching. The result is more accurate control.
Sumpless Single-Stage Converters with PTO Drives
For vehicle applications with power-shift transmissions. Available in 11, 13, 14,
14.5, 16, 17.5, 18.5, 21, and 23" sizes. Capacities range from 40 to 1350 hp. Power
take-off points provided for driving auxiliary hydraulic pumps. A modulating clutch
to provide power dividing capability is available in most sizes.
Twin Disc builds a complete line of Single-Stage Torque Converters including the
1100, 1300, 1400, 1450, 1500, 1600, 1700, 1750, 1800, 1850, 2100 and 2300 Series.
The first two digits in the series number indicate the approximate circuit size
in inches. Bulletin 510.
"Stripped" Units for OEM In-line Design
Available to manufacturers who want to incorporate a torque converter into their
own drive line arrangement. Designed to run in SAE 1OW heavy-duty motor oil, they
are furnished less outer housing. Available in all circuit sizes. Free-wheeling
stator and lock-up clutch are optional features on the 16" and larger sizes. Modulated
input clutch available to divide power between PTO drives and torque converter.
Twin Disc Single-Stage Hydraulic Torque Converter Renewal Parts Kits
Twin Disc Single-Stage Hydraulic Torque Converter Renewal Parts Kits contain items
such as bearings, shims, gaskets, clutch driving plates, gauges, "O" rings, seals,
snap rings, piston rings, filer service kits, springs and miscellaneous small parts
in one complete package. Twin Disc has four basic Single-Stage Torque Converter
Overhaul Kits for Models 6-CO-1504 equipped with an SP-111 Clutch; 6-CO-1512 equipped
with an SP-211 Clutch, and 6-C-1309 and 6-CO-1309 equipped with an SP-111 Clutch.
INDUSTRIAL SINGLE-STAGE TORQUE CONVERTERS - STATIONARY HOUSING TYPE
These units are available in 16, 20, 22, 26 and 34" TYPE FOUR circuit sizes and
they are custom-built for specific requirements. The TYPE FOUR torque converter's
features affirm it is a torque converter representative of the highest degree in
the state of the art. Stationary housing, high torque ratio torque converters have
exceptional capability for hoisting and lowering from light to heavy loads over
extreme speed ranges. A wide variety of input adapters and clutches, gear boxes,
output shaft configurations, and the optional 2800 Series Power-Shift Transmission
make the TYPE FOUR torque converters a highly versatile series.
TYPE FOUR HYDRAULIC TORQUE CONVERTERS
Designed specifically for the oil and gas industries, these units transfer power
from diesel engines and electric motors up to 2610 kW (3500 hp). Offered in 20,
22, 26 and 34" circuit sizes, these converters provide higher torque multiplication
and utilize prime mover power over a greater operating range than previous torque
converters used in oil field applications. Request Bulletin 850.
THREE-STAGE HYDRAULIC TORQUE CONVERTERS
The Twin Disc Three-Stage Torque Converter design-incorporating three rings of turbine
blades and two sets of reactor or stator blades-develops a very high torque factor-up
to five times engine output torque when at stall. Three series of Twin Disc Three-Stage
Torque Converters are offered. The 10,000 Series is rated for applications up to
335 hp at 2400 rpm; the Standard-Duty 11,500 Series to 420 hp at 2200 rpm; the Heavy-Duty
11,500 Series to 580 hp at 2200 rpm. Bulletin 135.
MODEL F UNITS
Bolts directly to the engine flywheel housing. A positive gear-tooth drive transmits
power from fly-wheel with no clutch. Model F input drive is available on all sizes.
MODEL CF UNITS
Also bolts to engine flywheel housing, but has a clutch between engine flywheel
and converter pump wheel. Available in all sizes.
MODEL CO AND FO UNITS
Model CO units are equipped with front-end disconnect clutch and overspeed or boom-lowering
freewheel. Model FO units are open-end, flywheel-mounted torque converters with
overspeed or boom-lowering freewheel. Units are available in the 10,000 Series.
INPUT AND OUTPUT COMBINATIONS
A variety of output combinations is available with various three-stage converters.
Type B is a chain housing. This is available with both the 10,000 and the Standard-Duty
11,500 Series. Type C-1 output is a straight shaft for direct connection to the
driven load; the Type C-2 is a flanged shaft for universal joint connection; Type
C-3 is similar to the Type C-1 with extra-heavy bearings for side loads. The Heavy-Duty
11,500 Series converters offered with a heavy-duty Type C-3 output. This series
adaptable to all applications required to withstand heavy side-pull loads.
