Ive been wrenching for 30years, but Im no expert at anything, done just about everything once or more in some cases except rebuild a transmission, therefore I know very little about their internals, however I have replaced(swapped out) several...
cutting to the chase, this is my first AOD to handle and I am having one hell of a time trying to get the torque converter(TRQC) seated properly... is there a trick to this? Ive been trying for a week meow, to get this thing seated, trying to find info on the internet, and Im at a loss. Im figured that I need 1" from the face of the bellhousing to the seat around the studs on the torque converter for the flywheel to mount to, Im off about 3/8" to 1/2".
here are the facts: 1: 1990 bronco, originally a 302/AOD, bought without engine, everything else intact...
2: bought 1991 302 out of an f150, replaced flywheel to AOD from e4od... 164 teeth, 50oz external weight
3:I thought maybe the TRQC that came with truck was wrong, bought a new one, exactly the same problem...
4:Measurements- the depth of the TRQC is 6-3/4" from front (goes into flywheel) to end that sinks into pump...
5: end of input shaft to pump is 6-1/2" so a little shorter that the converter depth
6:flywheel face to inspection plate on block is <1" by a couple of butthairs...
7: end of input shaft to face of bellhousing .437" (handy digital micrometer)
8: tip of TRQC(goes into flywheel) to flywheel seat around stud is .866"
9:Inner shaft once pulled out measures 15-7/8" in length, and after I stick it in the TRQC its depth reaches 6-5/8" meaning the front thickness (toward the flywheel) of TRQC is 1/8" which is reasonable to me...
Calculations: 6.5"+.437"= 6.937" for total depth from face of bellhousing to pump face
6.937"-6.75"(depth of TRQC)=.187" is bellhousing face to front of TRQC when installed properly?
.187"+.866"(#8 above)= 1.053" which should be just enough room for the flywheel and allow tranny to seat against block, provided i could get the TRQC all the way seated.
Observations: Ive heard of mushrooming the inner input shaft but mine appears do be fine, no apparent damage to splines on either side... on the input shafts, the middle or inner hollow shaft has a tiny bit of wobble to it... the TRQC has stamped on the side "20g" which i assume is a weight for balance, "58A" stamped near a stud with several what appears to be intentional marks through it "55A" stamped near another stud not crossed out, also "55A" in paint stick on back of TRQC.
anything to help or point me in the right direction? something is wrong here and Im at a loss ... :banghead
