245 mm Identification

245 mm IDENTIFICATION




The 245 mm dia torque converter I.D. code works the same way as the 298 mm converters, but with different meanings.

The first digit of a 245 mm converter refers to the application.

F = Front wheel drive
H = Rear wheel drive (except THM 180's)
S = THM 180

The second digit is the "K" factor. The chart shows the "K" factor for each code along with the stall speed. Note: The "K" factor on a 245 mm torque converter is multiplied by 11.6438 to get the stall speed.

CODE "K" FACTOR STALL SPEED

A = 240 -2795
B = 220 -2560
C = 205 -2385
D = 180 -2095
E = 160 -1860
F = 148 -1720
G = 140 -1630
H = 130 -1514
J = 177 -2061
K = 237 -2760
L = 163 -1897
M = 131 -1525
N = 218 -2538
Y = 122 -1420
Z = 203 -2363

The third digit refers to the clutch type.

CODE DAMPER TYPE

0 = No converter clutch
1 = 12O ft/lb
2 = 104 ft/lb
3 = 170 ft/lb
4 = 215 ft/lb Heavy Duty
5 = 215 ft/lb *RTC
6 = 170 ft/lb Heavy Duty
7 = 215 ft/lb *RTC Heavy Duty
8 = Viscous Clutch
9 = 240 ft/lb
A = 215 ft/lb
B = 215 ft/lb *RTC

* RTC = Reverse Torque Control (poppet valve)

The fourth digit (optional) refers to the type of cover used.

CODE COVER TYPE (APPLICATION)

A = FWD 208.2 mm Bolt Circle
B = FWD 237.0 mm Bolt Circle
C = FWD 237.0 mm Bolt Circle (viscous Clutch)
D = RWD 247.65 mm Bolt Circle
E = RWD 237.0 mm Bolt Circle, No Converter Clutch *
F = RWD 237.0 mm Bolt Circle *
G = RWD 247.65 mm Bolt Circle *
H = RWD 247.65 mm Bolt Circle, No Converter Clutch *
K = RWD 237.0 mm Bolt Circle, No Converter Clutch *
P = THM 180 ISUZU
R = THM 180 Opel
S = THM 180 BMW

* 180 degree weld on each lug

Look at the code on the torque converter in figure 6 page 5. You can easily identify it as a front wheel drive model. (The first code is an "F"). The stall speed is 2760 (the second code is a "K"), and it has a damper assembly rated at 120 ft/lb's (the third code is a "1". Notice that the fourth code has been omitted.
