The factory pilot bearing is a needle bearing with grease seals at both ends. It costs about $10 and works very well as long as the lubrication is there, the transmission is aligned correctly from the factory to the flywheel, and most importantly, the driver does not ride the clutch pedal at stops, etc.

If one of the above is a problem and the input shaft has gotten scored, polish it with smooth aluminum oxide paper (best to end up with 600 and 800 grit, oiled). You can buy an oilite bronze bushing for about $3 from a bearing house. A standard size that works for 1994-up diesel Rams is 3/4" ID, 1" OD, 1. 125" long.

If you suspect the transmission is not aligned properly by the dowels, check it with a dial indicator attached to the crankshaft. Fix it with offset dowels--see the factory Service Manual.

JOE.
I HAVE'NT CHECKED THE YOU VEH SPEC'S BUT MY 96 HAD A ROLLER BEARING HELD TOGETHER WITH A WIRE CAGE AS DO THE OTHER'S OF THIS VINTAGE.
NOW WITH YOUR DIMENSION'S LETS DO THE MATH. 1. 25 OD. -. 75 ID.
THAT LEAVES . 50 NOW, WITH A ROLLER BEARING ON THE TOP SIDE AND ONE ON THE BOTTOM SIDE WE MUST DIVIDE THIS FACTOR BY TWO (2) THIS GIVES US ROOM FOR A NEEDLE BEARING OF . 25 RIGHT??? THE ONE'S I PUT IN MY RIG FROM THE MOPAR PARTS,HAD NO ROOM FOR A SEAL,AND WITH OUT CHECKING MY SERV. BOOK I REMEMBER IT SAYING TO APPLY A SMALL AMOUNT OF GREASE TO EASE transmission INSTULATION. RIGHT??
THAT IS THE SECOND TIME SOMEONE TRIE'D TO TELL ME THE HOLE WAS OFF CENTER,AND THE OTHER GUY WASN'T THE ONE THAT ENLARGED THE HOLE FOR A BIGGER BEARING ,AND I CHECKED THE FLYWHEEL BEFORE I GAVE IT TO HIM AND AFTER I GOT IT BACK,AFTER ALL WE ALL HAVE THOSE BRAIN GAP'S. THERE MAY HAVE BEEN A FACTORY GOOF IN THIS AREA BUT IN MY CASE NOT.
I JUST WISH I HAD HAD THE COMPOSITE THEN IN STEAD OF TRYING THE ROLLER BEARING SET UP A JAYCO FLEET MECH,SAID HE HAD LUCK WITH,I RAN ACROSS IT QUITE BY ACCIDENT,WHEN I WAS PICKING UP A CLUTCH DISC FOR A FRIEND.
AS FOR CLUTCH USEAGE,WHAT'S YOUR GUESS?
AS A MECH,IN TRK LEASING,HAVING TO R & R 13-10-18 SPD'S,AND THE 14-15 CLUTCH'S TO SAY NOTHING OF THE FLY WHEEL. NOT AN ISSUE.
ON ANOTHER NOTE I CAN SAY DC KNOWS OF THE COMPOSITE BUSHING AND SEEMED INTERESTED!!
WITH YOUR POST AND MINE MAYBE MORE WON'T USE THAT PEDAL FOR A FOOT REST.

forgot the 0's
should have beey . 500 & . 250 what can i say it's late !!!
yes i do have e-mail you haven't found it??
have a good evening.
OH YES check this out if the is any kind of a std trans in your drive,yard, shop.

If you recheck my post, the OD is 1". The factory needle bearing comes greased and has rubber lip seals on both ends. Each time I put in a clutch I wonder whether to use a new factory bearing or the oilite bronze bushing. The former should last longer with proper treatment, and not sling grease onto the flywheel pocket. However, if it fails, it will damage the transmission input shaft. Regardless, your emphasis not to ride the clutch needs to be carefully considered by all. I have seen too many cases where an owner does not think he rides the clutch "too much. " The best training device is a clutch with so much pedal pressure that you _can't_ hold it down very long. That teaches you not to ride the clutch, ever.

Joseph,

There is another thing to consider about a needle bearing failure. If it fails it can collapse and jam so that it siezes the transmission input shaft. Some years ago my daughter's car did this and she could not shift it. It was a real bear to get the transmission out of it without breaking anything. I don't think this could happen with the oilite bearing.

stand corrected i miss stated 1. 25" BUT as i stated and the math is correct that little steel needle bearing is still only 1/4 " in dia. and if you go to your local d/c dealer and order a input shaft bearing it is a wire cage containing steel roller bearing's and not a drop of grease and if you roll up the outer end of the steel cage there is no room to install a seal lip. keep in mind the lip of the cage has to be rolled up atleast half the . 250th's which is approx. . 125 th's
which leaves . 125 for a non supported lip to hold grease in ??????????????????????????????
also if you think the bushing you stated is the answer. to a point your are correct. no cage to break and no needle's crawling up on each other locking the input shaft to the crank shaft. these were used in the early years and were beat out and the new design as stated above came in to use.
and still get beat out. cage failure. you have to ask your self if the bushing you stated is the answer why did dodge go to the roller bearing & quit using it.
NOW. before i tryed this composite bushing i had the flywheel bore'd and installed a roller ball bearing and being the input shaft of a size to small to accept a standard pilot bearing you have to install a bushing which due to the torque and vib's will and did get beat out,as did many others -of owners that tryed this before me.
Also. . if you are one that insists on using the clutch pedal as a foot stool you are going to cause premature throw out bearing failure--but the clutch & throw-out
bearing are not connected to the pilot shaft and would be a streach to say the operator is puting a load on the pilot shaft bearing. That will only occure when you are engaging and dis-engaging the clutch by puting a load on the transmission with torque fron the eng.
Where is this composite used?? brake pads-clutch faceing,--and where so. bend clutch found it used(by doing some machine work for a local mfg.co. found it used in industrial machines for bearings). and the rest of the story-- you will have to ask them i thought it was rather funny my self.
I DON'T care if you use it or not,i'm not in the bussiness and get no benfits from it sale or use,just passing on the info. and if you ever experance the lock-up as you are enterering a toll booth & are cut of by another vehicle and have to disengage as you dive side ways and no clutch you better be able to think fast.
WE DON'T have to get our backs up or be defencive because we own dodges because the chevy"s and ford's sticks have the same proplem.
If you ever have the transmission out as i said it is the is the best safty up-date ,& money you can invest,the wife or kid could be behind the wheel.

Thank you tdrmbramr, for using mixed case letters in your posts. It makes reading posts using only upper cased letters very time consuming to read. Usually I will just bypass them. Thanks again. John

The pilot bearing needles are smaller than 1/8" diameter. 1" od - 3/4" id = 1/8" per side for cage and needle. I haven't measured them but they are in the range of 0. 06-0. 09" diameter.

There is a load on the pilot bearing when you are at a stoplight with the clutch depressed, in that the bearing is spinning at engine speed and the input shaft of the transmission is not turning (transmission is in gear, rear wheels are not turning). Those little needles are spinning around the input shaft, and the captured grease supply is pretty small to dissipate heat (Mopar does supply it greased and with lip seals in the ends of the cage or housing). The Mopar number for the bearing is 52107562AB. I haven't personally tried anything but this bearing in the 94 up Rams, so cannot comment on the lifetime of the bronze or composite bushings.
