Hi guys.
I´m in the middle of rebuilding M5R2 transmission of my ´89 F150.

I got it disassembled and noticed that all my outer bearing races slips in and out really easily from casings bearing bores. ALL of them,input shaft,output and both countershaft bearings. It seems like the outer races have spin on the bores? So the main question is,is my transmission case ruined??? How tight they should fit in there? Is there anything i could do about it if they should fit tightly or should i try to find another case? Is it possible to use somekind if bearing mount liquid or something?

I´ll hope that´s not the case because these trannys are nonexistent in my country, and it would cost pretty much to buy another case and rebuild kit AND some other parts that i noticed were worn out.
If i need another case,i think it´ll be easier just to buy rebuilt tranny from US.

If the aluminum isn't chewed up badly, you might be able to secure them with a small amount of red Locktite. The races are pressed into place against the retainer plates as well under load. The real concern is getting them in the right place since once that stuff cures there won't be any moving them.
If the aluminum is chewed up and you need a case, there are people on here who have spare empty cases and other parts.

 

Hi,and thanks for answering.

Here´s a couple of pictures of my parts.

Here is picture of rear bearing retainer plate,you can see that there´s a mark left by mainshaft bearings outer race.



This is rear mainshaft bearings outer race.



Rear bores.



Front bores.



Countershaft front bore looks most damaged when you look at it but it was tightest of them all to get out. Input bearing and mainshaft bearing races just fell off when i took retainer plates off? I did not have to use anykind of force to get them out.

Any idea how much people are asking of empty case?

Those don't look all that bad. Looks more like machining marks rather than spin marks. There will be a difference in the color of staining where something was pressed against the plates, so that's pretty normal.
As far as cost, that varies depending on condition. Shipping would probably be the killer though.

 

I think the case looks normal to me too, the bearings are not press fit in that case, they will just fall out. The rear bearing retainer has typical wear too, you can buy that piece if needed, sometimes I use a shim from a rear end bearing kit to shim it back tight.
