Asian-Warner’s popularity grows
By now most rebuilders are presented with a task of rebuilding the Isuzu Asian-Warner torque converter. This converter is plagued with many problems. Factory bearings are inadequate, as with most foreign-made large diameter truck converters.
The front cover thrust washer is also a major concern of redesign. From the factory, this converter contains a plastic thrust washer that is prone to breakage even under the slightest drop to the floor. You MUST replace this washer with a new OEM brass washer, available in March from Sonnax.
The second area of concern is the pilot, shown in the bottom photo to the right. Both wear and complete breakage of this pilot are quite common. Replacement pilots are available and considered a necessary replacement.
Finally, replacement bearings are the last area of concern. Bearing failure is almost guaranteed if you do not replace them at the time of rebuild. Bearings are available and can be retrofitted with a small amount of machine work.
