702 Roller Stuck In Gear ??

Recommended Posts

squonk

I'm going with the froze bearing. Wheel would still roll if the axle splines were stripped. Unless something "broke" and jammed a differential pinion. The differential action would allow the pinions on the non rolling wheel to "walk around the axle  gear and the large gear would move which is what I think is happening.

Believe me, I'm as stumped and curious as you.  The thing that really gets me, a bearing can freeze, but it usually doesn't freeze up a shaft...especially when it had oil in it and was sitting in a garage.  I'm wondering if the owner before you was in that trans and did something with the differential pinions.  The fact that your differential rotates and doesn't turn the right axle means something is missing or something is broke inside the differential.

   Squonk is correct above.  The right could be jammed or froze and the differential would still function.  The fact that you can turn the left and the right sits there says it is more then a froze bearing.  With a fully functioning differential and one axle froze, you would not be able to rotate the other wheel in neutral.  Welp, open her up and let's see.

What's odd that one wheel rolls free but the other locked up? Points to a differental problem. 

Odd thing is it rolled before it sat. :confusion-confused:

Steve, I believe if the axle is froze, The differential will still function and allow the other side to turn. The pinions will walk around the frozen axle gear. Think of the axle gear as the Sun and the pinion gears are planets. The will rotate around that Sun gear. This is how automatic transmissions in cars work. Planetary gear sets. Also when working on car differentials, I could lock the brake on one wheel and spin the opposite side to get the gear case to rotate to allow access to the pinion shaft bolt. Can't wait to see what he finds! :)

OK...I have a spare 3 speed transmission in the garage and I went out there to see if I knew what I was talking about...  @squonk

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

OK, I was wrong, kind of.  In neutral, spinning one axle...the other goes in the opposite direction (that is internal in the differential).  You can stop one axle and the other can still turn, but instead of spinning pinions, you are turning the whole differential and it is spinning like Mike said.  So, it could very well be the right outer axle bearing is junk and holding the right axle...and that is all that is wrong.  :occasion-xmas:

I don't know, but Mike would want to get it tested for acidity.  It's got to have iron in it. :hilarious:

SOOOOOO , i couldn't stand it and started working on the trans this evening.  I had this metal pan out of an old fridge and used these 2x4's under the trans and the combination worked perfect. 

 

BUT , i can get the half of the case as high as the drive pulley shaft and that is as far as it wanted to go , and i didn't want to try to force it any farther without asking on here. The hub is stuck on the axle but good , i hope that isn't what is keeping the case from coming off because the axle will have to go in the press to get the hub off.

 

The good thing is there was very little water in the oil that was left in the trans and no rust that i can see so far !! Well, no really bad rust.

 

Is the hub holding me up from getting the case off or do i have to get angry with it ???

 

Also , the big bearing in the case on the side that the axle wouldn't turn looks perfect and rolls eeeeeasy. At least that is not the problem.

You will need to get that hub off. A bottle jack, some long bolts and another hub or sheet of 1/4" steel can make a hub behave.

Can you grab that axle and turn it now? Thinking maybe that axle was stuck in the differential carrier.

Yep , the axle will turn now with the cases apart. I guess that is kinda good ??

 

I tried to get the hub off the way 953 Nut has pictured with a two ton bottle jack and the hub is not having it , still won't budge. If there is not a workaround to get the cases apart , I think the only thing I can do is cut a chunk out of the hub or a slot in it and wedge something in the slot ?? I am not an original kind of person , so i do not mind putting newer style hubs on if i can't find a three bolt hub.

 

Wifey says we are mowing today , so that will blow most of my day , UGH. I have a transmission to get apart !!

Since,cents scents I have never been inside one of these transmissions, I a$$umed the axle rode on that outer brg. But I see what I would call the differential carrier rides there. I think the axle is stuck or was stuck in that carrier. That would still allow the other side to rotate when jacked up.

Could be the rust on the axle causing the problem. To the necked eye , it doesn't look bad in there , but the camera sure does see it .

 

I want to take it all apart anyhow and clean everything , no turning back !!

I think there is enough rust in there that you want to check every bearing.

1st, the 1533 ball bearings were never the problem...the differential sets in those bearings and the differential was OK and turned.  2nd, that rust you see on the axle does nothing but look like rust.  That end of the axle rides in the axle gear and is held in place by the pinions.  (and we know the pinions were turning)

  It almost has to be the right side outer needle bearing.

   Can you get the other hub off???  If you can, you can pull off the deep half with the differential stuck in that side.  Another option is to get that differential back in place and try to loosen and take out the 4 bolts holding the differential together...if you can get your hands and a wrench in there.  The 3rd option is to take a 4" grinder and carefully cut 2 slots down the length of the stuck hub.  You do not have to go all the way through, just close.  Take a chisel and hammer and the cast metal will snap apart.  :occasion-xmas:

   On a lighter note, I really understand starting this last night.  These transmissions are so easy to work on (once you get the hubs, & pulleys off) that it can drive you nuts trying to figure out what the heck is wrong.  :USA:

BTW...all of the inside gears look great.  Change the seals, and maybe 1 or 2 bearings, clean it out and put it back together.  :thumbs:
