O.E.M. = “Original Equipment Manufacturer”
In this video we looked at the D540 & D545 torque converters, which is found in large GM trucks with an Allison 400 transmission.
As a result of heavy torque loads in these converters, the turbine fins can become loose; causing noise and stress cracks to the turbine body.
To fix this problem, we furnace-braze each individual turbine, which keeps the fins from becoming loose. Then we weld an additional support ring to the crown of the turbine to provide even greater support.
These are just some of the ways DACCO is making OEM converters better.
