A transmission could not work without them, even though a few applications have used a bushing to seal oil pressure. These small pieces of metal, or other material, have been part of the automatic-transmission landscape since inception. The output shaft nut socket is available from Ford, part number 307-649, for about 250 to 300. There have been many ways to plug a hole (so to speak), and sealing rings are but one. This nut requires the special tool and lots of heat. The output nut tool is identical to the Torqshift (5R110W) nut just bigger. Off Shore for Bushings, Filters, Metal Clad Seals and Sealing Rings. Transmission model: 5R110W Part type: Sealing Ring Description. This can be corrected easily, as the valve body is on top of the transmission just remove the valve body, index the lever into the pocket and reattach the valve body to the case. You need to remove this nut to service the low/reverse piston assembly and the rear case seal. pan gasket, does not include bonded rubber intermediate piston servos or accumulators >. This transmission element was designed as seals for needle bearings shafts and hubs Hermetic rings also may be reffered to this group of transmission parts. When the valve body is installed so that the lever of the variable-ratio-control valve misses the drive-pulley-follower pocket, the valve is unable to respond to the movement of the ratio-control motor, preventing ratio changes by the pulleys and keeping the transmission in low range. Mercedes recommends replacing the O-Rings and Bushings on the case connector when replacing the valve body or conductor plate in order to avoid future leakage. As a result of this action, it becomes a mechanical sensor influencing the variable-ratio-control valve, tailoring the feed fluid into the drive-pulley piston. With one end of the lever being in the ratio-control motor and the other end being in the drive-pulley follower (refer to Figure 5), the follower acts as a movable pivot point for the lever. complete sealing rings kit solenoid screen & gasket o-rings. This spring-loaded follower rides on the movable drive-pulley half as shown in Figure 4 and reacts to the movement of the drive pulley as it changes ratios. 5r110w transmission overhaul kit by transtec fits 03+ ford super duty (16002a) menu. The opposite end of this lever then sits inside a pocket of the drive-pulley follower, as shown in Figure 3 from the valve-body side of the case with the valve body removed.
The ratio-control motor indexes with a lever that is attached to the variable-ratio-control valve in the valve body (see Figure 2). The ratio-control motor (stepper motor) is a bi-directional device situated on top of the valve body (see Figure 1). A common failure in the Ford 5R110W occurs when the low/reverse retaining ring pops out of the case groove, causing slips in reverse and severe damage to the case lugs. The variable-ratio-control-valve lever has not been indexed correctly into the drive-pulley-follower pocket, or the ratio-control-motor lever has been wedged between the pintle and the housing.
