===T-350 Pump assembly=== '''Notice''' the scraped and split T-350 low reverse friction in the intermediate piston cavity. This slightly tightens the intermediate clutch clearance to achieve cleaner 1-2 shift.

[[File:T-350_pump_n_piston.jpg|thumb|300px|left|T-350 pump with intermediate piston installed]]<br style="clear:both"/> Sealing rings on the T-350 pump stator. Remove the second ring from the bottom if dual feeding. [[File:T-350_stator_rings.jpg|thumb|300px|left|Sealing rings on pump]] <br style="clear:both"/> Pump gear install. Note the orientation of the tangs on the inner gear. They are offset. They should face away from the seal. Incorrect installation will result in pump failure and converter damage. [[File:T-350_pump_half.jpg|thumb|300px|left|Notice the T-350 inner pump gear tangs, they must be '''up''' as seen here]] <br style="clear:both"/> Notice the dowel pins threaded into the case, you use these and the case to align the pump halves. [[File:T-350_pump_alignment.jpg|thumb|300px|left|One method to align the T-350 pump halves shown]] <br style="clear:both"/> This is an example of to air check the T-350 forward and direct drum. After everything is assembled, I place the T-350 drums on the pump (above a hole in the bench) with all sealing rings in place, thrust washers or bearings. Use a rubber tipped air nozzle to apply air to the passages around the pump circumference. As you apply air to the correct passages, you will see and hear the drums apply the clutches. Be sure there are no leaks from the lip seals. There will usually be some minor leakage at the sealing rings. Iron rings air check better than teflon on the bench. [[File:T-350_air_check_pump.jpg|thumb|300px|left|One method to air check T-350 clutch drums in the pump shown. Refer to build manual for locations]] <br style="clear:both"/> T-350 Drums installed in the transmission case. Ready for intermediate pressure plate install. Ensure the lugs of the direct drum are engaged with the sun shell. They should be slightly below the top edge of the sun shell. If you do not get complete engagement, the input shaft will not turn when you install the pump and begin to tighten it. You can also see the braking band installed.
