SUBJECT: TORQUE CONVERTER (LPG AND GAS ONLY)

A new serviceable torque converter is available. The new converter offers the following advantages:

1. The new converter is a serviceable unit. It may be disassembled to check for wear and only the

worn or failed parts need to be replaced.

2. The turbine spline area is increased to give significantly longer life to the splines on the single

speed transmission.

3. The stator spline area is increased to give significantly longer life to the splines on the two speed

transmission.

4. The new torque converter provides better cooling characteristics reducing transmission operating

temperatures.

Units with the sealed converter may be altered with a 236344 conversion kit. In addition to the kit a
new engine crankshaft seal and oil pan gasket should be ordered. The flywheel is eliminated in the
change. On units with timing marks on the flywheel a crankshaft pulley and timing indicator are
required. The old crankshaft pulley may also be marked according to Figure 3. On the S30-50C and
S60-100B the flywheel housing must be altered to Figure 2 specifications.

Parts Involved:

Refer to Figure 1.

236340 housing. Install the new or altered housing.

12. Reconnect the engine and transmission by carefully slipping the transmission input shaft into the

converter and bolting the converter housing to the engine adapter plate.

13. Remove and disassemble the starter. Replace the original starter drive assembly with the new

one. Reassemble and reinstall the starter using the new adapter plate and capscrews and the
original lockwashers.

14. Reinstall the engine and transmission.
