Today was used to attack the center compensator casting....specifically the thrust washers in the center of the unit where the axle stub gears are located...
I did some snooping and then frequented the local tranny shop.....
Picked up a pair of washers from a FORD....84GT7D428AA thrust washers
"Front drum to direct drum thrust washer" These are a 4 tang thrust washer that fits the inner gears sweeeeeeet....
I put the stack together and measured the clearance with feeler gauges.
The assembly is worn a bit off from side to side.....so the amount of metal to be cut off the center casting was not the same on both sides.
I WANTED .010" CLEARANCE....BUT WE ARE CLOSE
Milled the one side .022" and the other .037" to get things happy
Set things up to cut 4 little notches for the thrust bearing tangs to fit.
Got this all done....feeling real smug....then it happened.
Stacked everything together and dropped the thin washer between the inner gears and things are off by 1/4" or so.
OMG.....WTF
Day started way too early....
Not paying close enough attention and dropped the one center gear into the compensator outer case and put it in with the long hub to the center.....
THIS WILL NOT WORK
After looking at it and thinking OMG ...this is gonna hurt.
Then it dawned on me what I had done.
The total material removed was only ..059"....you can't make this into 1/4"
Swapped the gear position and life is good.
Arrrrrgh....time to put the toys away for the night.....
Looking good....I want to bolt the cases all together with 3 bolts to be sure the inner clearances are where I want them....
The little Ford washers really spiff up that area...
Plenty of bearing area, and these washers are meant to be rubbed on....
No mods needed to be done on these washers....right out of the box...good to go.
They are .062" thick....
Pics of the machining of the hub area as well as the tang notches.....
Almost looks factory...
I wonder why the factory used such crappy washers.
Tomorrow it's gear deburing time..... This old girl may not be the prettiest one at the ball....but it is gonna be just fine......
Bunches of pix
See the one gear on edge.....put it in backwards and you will wonder wassssssssup ....:th_lmao:
