ProTorque

The "one size fits all" theory doesn't work for performance torque converters. Many companies erroneously advertise 2500rpm or 3500rpm stall-speed torque converters. As we mentioned earlier in "Torque Converter Fact and Function," stall speed is determined by several factors such as engine torque, weight of vehicle, and gear ratio-so how do they know they are selling you a 3500rpm torque converter? Pro-Torque has the ability to consider the specifications of your vehicle and the driving characteristics that you desire and build a custom torque converter that will meet your requirements. By filling out the Pro-Torque specification sheet we will be able to determine which core style to use,

what overall diameter torque converter would be best, what stator modifications are needed, and which impeller and turbine fin angle to use for the desired result. High stall speed race units may get a special billet front cover and anti-ballooning plates as well. Pro-Torque's 25-years-plus experience assure that you will get the best converter. Shown below are just a few of the steps Pro-Torque uses to build a high performance, custom torque converter. Our custom purpose-built machines ensure precise machining and assembly. Pro-Torque uses only the highest materials and components in our torque converters. Remember- Quality Doesn't Cost, It Pays!

ProTorque Overview

Cores are received

The first step in custom building any torque converter is to cut the core assembly apart. Pro-Torque is one of the few companies that has the precision tooling to keep everything concentric (aligned) throughout the process.

The original drive hub is machined off. It will be replaced with a custom billet-steel hub that provides a perfect transmission seal surface and is made out of tougher alloy.

Pro-Torque makes as many of our own components as possible to ensure quality control. Here a billet drive hub is being machined for the transmission pump engagement tang.

On lock up converters, the front clutch apply surface is inspected, machined if necessary, and polished for a smooth finish. A wider-than stock clutch surface will be used for increased holding capacity.

The stator assembly partially determines the stall speed and the driving characteristics of a converter. Pro-Torque custom machines each stator for a given application.

Changing the angle of the impeller fins by bending with a special tool also determines stall speed and drive ability.

Before assembly takes place the impeller and turbine have the fins furnace brazed in place for strength and to prevent the fin angle from changing.

ProTorque cuts the original lock up clutch lining off of the damper assembly and bonds a wider, ceramic-impregnated clutch material in it's place. The special bonding press used is just one of ProTorque's custom built machines.

Components are inspected and carefully assembled.

This pneumatic press fixture precisely sets the "stack height" of the internal converter components while the outside housing is tack-welded in place. These internal clearances and the concentricity of the housing is critical to torque converter durability.

Each converter is finally finish welded in the Auto Weld computer controlled welding machine, then 100-percent leak checked with compressed air in a water tank.

Converters are then painted prior to packaging and shipment
