When reassembling the transmission, it needs to be in the verticle position, to make things fit. I have devised a simple stand that does this.
It is made from an old implement disk, a 12" piece of electrical conduit, 10" X 1" x 1/4" flat bar and a 5" piece of 1" X 1" angle.
The internals can be assembled, end play set and then it can be removed from the stand and placed flat on the table for final assembly.
As mentioned previously, a hole must be drilled in the front pump's high pressure port to accept the pre-charge pump output.
"X" marks the spot. (to drill)...Heh...(1/4" NPT for me)
When inspecting your transmission, one place is really very critical.
The front pump bushing contact area, where it rides inside the front planetary hub.
This is a sealing area that holds the high gear apply pressure. This one is too far gone to save....(Crap) It is easy to tell, just place the new bushing over it and it flops around a LOT. NOTE: that small oil hole seen near the copper thrust washer gets drilled out for extra oiling. (More later)
If you place the two gears in mesh, on a flat area and pull the bigger one with the smaller one without unmeshing, they are good to reuse.
Notice how far these get out of contact and barely stay engaged. They are almost out of spec.
A worn bushing contact area, the gear wear and the pump gear cavity side scratches and it all sez I need another pump.....
More tomorrow, (Yes, I am playing sick from work.) Miz
