The end float shim under the torrington bearing will no doubt be changed during case assembly. The complete pump assembly with new bushes, new torrington bearing, intermediate piston assembly, direct drum and forward drum rings, pump gasket and outer pump D ring. The width of the brand new inner and outer pump gears are checked for tolerance after being wet blocked flat. When machining the front pump surface, the rear thrust surface must also be machined for perfect alignment, this must be done without removing the rear pump half from the lathe. This is a perfect example of a pump half that has been so poorly machined from the factory that the large portion shown between the fingers has been completely missed and not machined at all.Īs with all of our Extreme transmissions particular attention is paid to the front surface of the pump ensuring that it is not only perfectly flat but machined 90 degrees to the alignment of the pump. There has been many times that we have found quite large bows within the case, some as large as 40 thou ( 1.00 mm ). The end result of the machine work shows the case now completely flat and free from any distortion it may have received over the years. The machine used was specially built for us as the surface is so large on many transmissions, milling such a large surface area will always distort the case as it builds up heat. This is a T/350 having is lower case machined dead flat as they are NEVER flat. As you can appreciate we tend not to itemise the exact contents of our kits. A lot of extra hard parts go into the Extreme T/350 with the front planetary, reaction bell, center support, rear annulus, TCI outer sprag ring and super wide band all added for extra strength. This shot above shows almost everything that is used to build the EXTREME T/350 with only the converter and rear annulus missing. This photo shows the transmission completely striped and coming out of the hot wash just before being taken to the rebuild room for inspection. The whole process from this stage to the final coat of paint will take three days while a standard unit can be built in one day. This is what the T/350 transmission looks like before we start to dismantle the unit and prepare it for the wash.
