I have cleaned and assembled all the components on my 4r100 as per the rebuild manual. My question is, i have set up the output shaft with the rear planetary ring gear and installed the snap ring. the output shaft has slight play when i move it forward and backward, and more play from side to side. should it be pretty snug against the park gear? does the shaft make contact with the case bushing? or does the output shaft get firm as the components are installed?

Also, I know there are no stack up clearance on the reverse clutches but i`m looking for some sort of guide. My clearance on the revers clutches are
0.056 in, does this seem good?
thanks for your reply

 

Output shaft movement at this stage is normal, the extension housing bushing or transfer case will help support the end of the shaft and the other components will support it from the front. It is always a good idea to replace the case bushings along with most of the others during a rebuild as well, they do like to wear

Rule of thumb is about .010 per clutch.

I think your clearance is acceptable.

 

thanks. I have changed out all the bushings in the trany. My kit is a heavy duty kit with extra clutches and frictions however, I dont want to dump too much in the rebuild and order different snap ring to meet the necessary clearance so i just went with the amount the stock was. the trany was ok except for the park gear bearing blowing out. It didnt damage anything. I did however use the trans go kit on the oil pump. Would this be a problem seeing i used the stock # of clutches? I will also be using the kit on the valve body.
I also changed all the bearings except for the forward planetary needle bearing. For the life of me I cant get it out and I dont want to damage anything so I left it alone. The bearing seems to be in good shape.
Just a note, my Reverse Planetary only has 3 gears where I have read it to be 4 or 6.
This van is a 1999 ford e250 (CNG) model, so I wonder if the trany was built differently.

 

Jk080, my friend was helping me rebuild the tranny but he removed the bushings in the pump without making note of their position. I have the debt of how far in the bushings go. Could you tell me which direction the bushings with the oil grove go on the front pump bushing? And which direction the stator bushing with the oil grove is to be installed in the stator? Also do I have to worry about the front pump bushing spinning when the converter is turning. I seen where 2 notch is made in the front pump bushing to avoid this. Thanks

 

Hope this answers your questions.








Sorry for the blurry pics. They are the best ones I have right now.

 

They help a lot. Thank you.

 

the info you sent helped me somewhat. its been some time since i worked on the trany. everything have been installed except for the oil pump. I have installed the bushings to the spec you gave me, but me input shaft wont go past the inner bushing. I have removed the bushing and pressed new ones in but still the same. before the bushing is pressed in, i put it over the shaft and it is OK, but once i press the bushing in the pump, it become smaller somehow and the shaft wont past it. I have replaced several bushing but the same thing. the outer bushing is fine,just the inner bushing
