t-90 problems

still...t-90 problems

So I adjusted the shift rods because I was unable to depress the clutch and shift through gears. That didnt work so I removed the inspection plate to ensure free movement of the throwout bearing and clutch. I do have free movement of those plus, I turned the engine over by hand and the gears only move when the clutch is depressed. what I had noticed at first before adjusting shift rods, was that the shift rod ends would not move freely. I removed the cover plate from atop of the tranny, and tried using a pry bar with minimal force to see if something was binding and nothing was. I couldnt find any information in the pubs. I think this might end up in a recycling yard.:?

 

Jack up the rear of the Jeep and put on Blocks One wheel off the ground if you have a regular diff-- both with a locker.
With the cover off, manually place the gears in neutral
Turn the wheels--- the gears in the trans should turn in neutral.

Look and see if you have a broken gear

if so


Drain the oil out of the tranny and remove the broken parts that may be jamming the gears

if not

Consider draining the oil to inspect the tranny guts.


T-90s are very simple transmissions and easy to understand and rebuild--
You will get it fixed eventually.

However maybe your clutch is just not releasing.

 

your t-90 is sad send it to me and it will be happy/i will not charge you

 

Did you replace the pilot bearing recently?

 

I have not changed out the pilot bearing Im thinking I should have. To further inform, I have the body off and driveshafts were allready removed. I did though just install the new clutch and assy. It was working fine b-4 I reinstalled the enigne. I had drained th efluid about 2 weeks ago, and wiped the inside sup woth lint-free rags and such, I did not see any metal particals at the time. I refilled it with synthetic oil, and was turnign throught the gears. So it has to be something I had just done. I am in the process of removing the enigne again to investigate.

 

Well I have the engine out, and I went ahead and drained the fluid out of the transmission to see if maybe something was stuck between the gears. I see nothing. I am still not being able to spin the transmission, or move the forks. the tnxfr moves freely in neut.

 

It looks as if that is what it might be, im trying to upload the pictures...if that is what it is, what is the cure?

 

picture is from camera phone

 

Looks like it's in two gears to me - though I'm not the most expert per T-90s. Neutral is both shift collars in the middle; one or the other shift collar slides over to go into gear, not both.

 

here's a view of the shift forks and mechanisms
lots of little parts in there

 

the FSM goes into detail about the shift interlock assy; since you didn't disassemble the trans, I doubt anything has changed there.
could it be one of the levers got bumped and put it into both gears ?
I wonder if playing/depressing one side or the other of the interlock will free up the fork(s) for shifting ?
pressure applied to the lever as well as the collar at the same time may jar it free

 

thanx fellas, Ill see what I can do.

 

Push reverse gear toward the neutral position while working the shift lever into neutral for that gear.


btw-

Why don't you convert to a top shifter housing?

 

Is there some literature or something on the procedures of switching to top mounted?

update= well I got it lose, and it spins freely, I have it in neutrual( i think ) i can hold on to the input shaft and spin the e-brake drum and the input dont move. So gotta lube it up and install the engine.

 

not really
you remove the side shift forks and linkage; plug the holes in the case.
The top shift tower/cover w/forks slides right down over and into the trans. You would need the floor tower cover, lots of those around.
The shift lever on the column should prob be removed as well.
If you do remove the side shift/column shift linkage, don't toss it, someone will want/need it.
