Reinsralling tranny

[AZ75CJ5]

Ok, got the new bell housing and going to be putting it back together. Taking a trip to napa to get all misc items. Can you all help with things I'm going to need to get. Im really excited to move onto this next step. Thanks again for all the help.


Want to send out a shout out to Willy's works down in Tucson, AZ. Good people and very knowledgeable. Thanks Rob

Am I missing something here or does this slide straight in?

What about these wires attatched to tranny. Which wires connect where? Any ideas?

 

[caveman]

Yes, It is suposed to slide straight in. If not, Then check to make sure the clutch plate splines are centered in the preasure plate. Sometimes you have to wiggle it and turn the input shaft to get it to line up. The wires go to the back up lights.

 

[AZ75CJ5]

Is there supposed to be a bearing at the end of tranny where goes into motor?

 

[hdgapeach]

The main shaft that sticks out the front of the Transmission will go through the clutch plate/pressure plate assembly. The nose of that shaft will actually stick in the back of the flywheel. The hole that the shaft fits in should have a pilot bushing (or pilot bearing, whichever is appropriate for your application) in there to center the shaft. That needed to be replaced while you had the bell housing off. I think this is what you're asking about.

Other than that bushing/bearing, the only other bearings at the front or in front of the Transmission is; the clutch disc throw out bearing that attaches to the shift fork in the bell housing, and the main shaft bearing in the front of the Transmission case.

Bell housing still off, havent started putting it back together. I did not take off the clutch or or pressure plate. Only tranny and bell housing. So I need to purchase a pilot bearing correct?

what about addtl things I am going to need? Right now on my list I have gasket for top of tranny (shifter), sealant, grease, spray paint (gonna paint tranny before I put it back in. What else do I need to get before I begin this job? Thanks again.

 

[hdgapeach]

Yep, a pilot bushing.

I'd go ahead and pull the pressure plate and check the condition of it and the clutch disc unless you know they are in good shape. Easier to check and see rather than having to pull it all back out to replace a burned out clutch in the near future. Besides, it makes it easier to get to the bushing you're intending to replace.

Rent or purchase a puller to get the present bushing out of the flywheel. If you have a Harbor Freight nearby, go ahead and buy one. Theirs is cheap and works just fine. If not, several of the auto parts chains rent the puller and reimburse you when you bring the tool back to the store. I tried several of the home remedy methods to get my bushing out and ended up renting the tool the first time. None of the "free" methods would work for me. Then I ordered one from HF and had it shipped so I have one when I need it now (lot more vehicles than just the CJ).

Check the throw out bearing also. Personally, I'd just get a new one and install it. Cheap insurance that you shouldn't have to go back in sometime soon just to replace that (kinda like mentioned above about the clutch disc and pressure plate).

Aside from those items, I'd check the condition of the clutch pedal linkage to the Transmission . It's a lot easier to access and replace what's worn out while you have the Transmission out of the way.

Clutch and pressuer plate was just replaced less than a month ago from my step dad, before he gave me the jeep. But when he put it back together I dont know why he didnt replace the bell housing (which had a bigger hole around where for goes in at), so I've had to go pull it off and put it all back together the right way.

This is what I've done thus far. I removed starter, removed bell housing from engine and pulled back the tranny. Purchased new bellhousing, fork, inner/outer springs, fork book, pivot ball and plates that cover bell housing. When I pulled tranny back there was no pivot bearing on the end of the main shaft. Should it have slid off with it when pulled tranny and bell housing off? Is it still in there and no need to buy new one? Guess I'm kinda confused now, lol...

 

[hdgapeach]

No. The pilot bushing is a friction fit inside the hole in the rear of the flywheel. That's why most of the time, it takes a puller to get it out of the flywheel. You'll have to tap the new one in the hole till it bottoms out. Similar to installing a wheel bearing outer race in an axle hub. Just be sure to go easy with the new one. Don't want to booger it up trying to drive it in the hole. When it hits bottom, it'll be further in than the outer surface of the flywheel. Dab some grease in the bushing before sending the Transmission shaft in the hole.

 

[AZ75CJ5]

So, if it didnt pull out when i pulled tranny it is still in there and doesnt need to be replaced. Correct? I for some reason, thought maybe it was supposed to be on the end of main shaft when I pulled tranny out and for some reason either lost it or was missing one in the first place.

If you have the tools to check it, measure the inside diameter of the pilot bushing and the outside diameter of the main shaft where it'll contact the bushing. If the bushing isn't wore out, give it a visual check for damage with a light and mirror so you can eyeball it. If it ain't damaged or wore out, grease it and reuse it.

Awesome.. That answers that question.

Don't forget a clutch plate alignment tool or you will never get the tranny all the way in. That bushing/bearing is actually pressed into the end of the crankshaft and is soft brass and will mushroom inward easily if you are not very careful installing it. If the one in there now is in good shape then grease it and leave it in there. A pair of long bolts with the heads cut off installed into the bell housing will go a long ways toward getting it in alignment for getting the tranny back in place. Saw a screwdriver slot in the end of those bolts for easy removal.

What about addtional things that I am going to need. Such as sealant, grease, etc. Is there as gasket or seal that goes from tranny to bell housing?

Nope No sealant...........One other bearing..........The throw out bearing should be hanging off your clutch or throughout fork that's attached to the inside of the bell housing. The Bearing rides on the candlestick housing that is attached to the front of the Transmission . This part surrounds the input shaft from the Tranny. A little anti-sezze on the OD of the housing where the bearing slides is a good idea. Once that's all in place the Transmission slides into the bell housing through the clutch throw out bearing and through the splines on your clutch disc and pilot bushing that is in the back of the crank...........the tranny will bottom out up against the face of the bell housing..........as mentioned two blind studs screwed into the two bottom holes of the bell housing will help hold and align the Tranny into the Bell Housing.............Good Luck!

Was told to use sealant on top bolts where shifter goes into tranny to avoid any possible leaking. Waste of money or good idea?

You first asked about Tranny to Bell housing and that's a "NO"

On the Shifter housing that complete flat surface can use a sealant including the bolts...........make sure the vent in the tranny that should be mounted somewhere in that housing is clear and free of any dirt & debris.......the only reason the shifter housing would ever leak up there is if the tranny case became pressurized from a plugged vent.........it your planning on running through deep water a vent with and extension like a hose to a higher elevation would be a good Idea..........

When you are sticking a threaded bolt (not a pipe thread) into an oil filled cavity to prevent seapage you should use an automotive thread sealer, that is exactly what it's made for. The stuff looks a lot like regular old pipe dope to me, but it must be made to take engine heat. It is inexpensive insurance too.

The bell housing isn't ful of oil so no gasket is required between the Transmission and bell housing.

Before you left Willys we did talk about the need or no need for a pilot bushing. Remember we talked about soaking the bushing in oil for at least 24 hours before installing the bushing. Also, if you pull your pressure plate you will need an AMC spline/clutch alignment tool to reinstall it. Rob offered to let you barrow the imput shaft rather than buying the tool. If I were you I'd get a flash light and get up there for a look. to inspect your bushing. The clutch is supposed to have only a few miles on it and pilot bushings are usually changed when a clutch is installed ..... but as we know a clutch installer doesn't usually use a pair of pliers to nibble out a hole in the clutch fork opening.

X2 on oil only with s bronze bushing. Never grease-
A real input shaft for the clutch disc alignment, is a much better tool than the wood or plastic so-called alignment tools out there.

I really would rather not pull pressure plate. Have looked in there with flashlight and everything looks brand new. Do I need a clutch alignement tool I do not pull pressure plate? If I have not removed anything other than bell housing I do not need to purchase a pilot bushing, correct?
