I typically hear it when. The noise is typically worse when the engine is in between and rpms. I would like to diagnose this problem, but more generally, what are some guidelines for diagnosing bearing problems in the clutch or drivetrain? Throw out bearings TOB usually make noise when only when you press the clutch pedal. The reason for this is, it is the only time it is engaged and actually can make a noise.

If you are hearing this particular noise at rpm when you aren't actuating the clutch, this can be ruled out almost immediately. Input shaft bearing will make noise most of the time at any engine speed, though can be more pronounced at a given engine speed. It can also make more noise under a given load.

A noise from the input shaft bearing will raise and lower with engine speed, and not with vehicle speed. You'll most likely hear it no matter what gear you are in. From your description, this seems most likely your issue.

The drive shaft support bearing will make noises which will raise and fall with vehicle speed.

It will make the noise regardless of engine speed. You can be in 3rd gear going 40 mph or 4th gear at 40 mph and should still be able to hear the same noise it's just an example Considering what you've said, I doubt this is your issue.

It may also be one of the carrier bearings within the transmission.

The thing is, though, whether a carrier bearing or an input shaft bearing, you'll need to have the transmission pulled to fix it. A good transmission shop should be able to give you the proper diagnosis. Sounds like the throwout bearing if you're hearing it mainly when you're operating the clutch pedal.

Throw out bearing, input shaft bearing, or drive shaft support bearing?View Full Version : Pilot Bearing v.

Pilot Bushing. I need some help on the debate listed above. Bushing Pro: Solid, will be "nicer" to the input shaft. Bushing Con: Won't last as long, will need to be replaced before the bearing. Bearing Pro: Will provide longer life, wear less.

Bearing Con: Not as "nice" to the input shaft. This is what my searching has given me I plan on putting about the crank. The trans is built to withstand HP.

I would have thought that too, but my research says that GM switched to a bearing for longer trouble free life. I think that the bushing is made from a softer metal. Pilot Bushings are made from a softer Bronze. They last a long time and are pretty easy on the input shaft of the transmission.

Pilot Bearings are made of steelof course. They theoretically will last longer than a bushingbecause of the material they are made ofand they are greased The later model Tremec transmissions work better with a bearingbecause the bearing supports the input shaft of the transmission with a closer tolerance than a bushing.

Most bushings on the market will allow more runout in the input shaft because the hole in the center is slightly larger. Nowas far as which one will last longer. Because of the very tight fit during assemblyI damaged and had to replace two pilot bearings.

Sothey didn't last very long at all. But that was an installation error on my part.

I've disassembled old Camaros withmiles on them and original GM pilot bushings in themand they weren't worn out. Sothe bushing will last just fine. A least till the next time you re-build the car. Thanks for the info Jeff! I am mating this to an LS6 with the help of an LS7 clutch. A few other manufacrues sell them and there are more rollers in them. It is claimed that the less rollers have longer life and less failures.

I think it works with the bushing. Since it doesn't have a huge effect on a vehicle in less than 20K miles or so I went ahead and put in the bushing. I am going to get the motor installed by the end of march and driving by the end of April at least around the block! I've read that the only modification is some grinding on the interior of the bell housing.

Thanks again for the help! We have a Dodge Cummins truck, the clutch was changed about 30, miles ago, then the pilot bearing fell apart internally, the rollers got bunched up and grabbed the nose of the trans shaft locking it like a roller clutch on a starter bendix.Jump over to the Events Forumto post events -- new ones or the ones we have been enjoying for some time.

It'll be bolted up to the original truck flywheel, bellhousing and granny gear 4 speed.

The donor motor came from a series car with a manual 3 speed. I'm pretty sure that motor originally came with a bronze pilot bushing in the end of the crank but it now has a roller bearing.

I'll be replacing the old bearing before the transplant. My question, is there any advantage to replacing it with another roller bearing, or should I go back in with a bushing? Thanks in advance, Steve. Copy Link to Clipboard. Re: Clutch pilot bushing vs roller bearing.

Dellrose, TN. Hotrod Lincoln. Using a needle bearing in that application is like putting lipstick on a pig- - - - -there's no real reason to do it, and the result might have some real downsides. There are too many moving parts that can fail in a roller bearing setup, so I can't imagine any good reason to substitute it for the old reliable oilite bushing that has worked for decades in untold millions of vehicles.

Even if it does, the needles are going nowhere as the front is sealed. Align the bell-housing and use the roller bearing. Its going to have less friction on the input shaft and improve shifting ability.

Can also cause clutch to hang up. Input issues are more of a vibration under a load. Jul 4, 3. My pilot bearing seized up around K miles and the tip of the input shaft was wearing against the inner diameter of the pilot bearing. I would get a grinding noise when I would release clutch. The trans bearing of the input shaft is pretty forgiving. That was fine upon inspection. Put in new pilot bearing, input shaft and clutch. Clutch was due anyway, had no more adjustment left in it.

Resurfaced flywheel too.

Pilot bushing vs bearing

I think the bushing has the longer longevity, but both can be hard to get out at times. Ive used both and thought the bearing had a smoother response. Badest Bronco in the World, that lives on my Block! Still in project mode. Remember, You can always live in your Bronco, You can never drive your house.

Bushing is cheaper. Bushing wear is gradual. I feel bushing is more tolerant of water. Bearing cost more. Bearing can last longer hold tight tolerance for life If when? Bearing more suspectable to water especially if seal is compromised. Bearing will work perfect up to the day it dies, bushings will gradually wear giving the transmission and clutch a worn feeling over time transmission input shaft misalignment.

Older transmissions have loose tolerances. They will tolerate the wear of a pilot bushing just fine.

Newer transmissions are much finer. The bearing will hold the input shaft truer longer. If the input shaft has a little wear to it common with used bushings I would stick to bushings. But if you had a slick new input shaft that was nice and polished, bearing providing I wasn't planning on drowning it all the time. This would also vary based on if the bearing had an inner race in it or used the input shaft as the inner race.

Mostly my observations at looking at a lot of parts and engineering over time.

What pilot bearing is needed for tko chevy to our amc 72 v-8 engine. Depends on bell housing depth relative to input shaft length. If the pilot on the input shaft engages to the stock pilot bore, a pilot bearing from a Jeep AMC 4. Edit: '89 Jeep Wrangler 4. If pilot on input shaft is further out, Advance Adapters makes a pilot bearing that engages the converter pilot bore.

Bushings are also available, if you prefer a bushing to a needle roller bearing. So I have a genuine bearing for a pilot bearing. No chance of that angry elephant sound in cold weather now.

Somewhere I wrote down all the measurements, but can't recall where I put that paper. I had to measure the input shaft depth into the back of the crank, so I could figure where the bearing needed to ride and so on to make the bushing or spacer to hold the bearing in the right spot in the back of the crank.

To the original question - since this is an AMC forum you aren't always going to find simple fast answers to things that marry non-AMC stuff into an AMC as if "everyone is doing it". You may be the only one who has done what you are doing as far as the people here, or you may be one of ten who has done it. But there's no book on how to adapt other stuff into AMC - it's a figure as you go.

No blueprints. I am NOT the only person to have ever put a 4. I wasn't really adapting anything weird or strange, and yet I had to do all the math and measurements and find a bearing to match my needs - and make the spacer on my lathe.

I even had to find out on my own that the flywheel for the 4. Not saying you won't find help or answers but when doing non-standard stuff - there's no real book on that. It's fabricate and figure as you go. So don't get discouraged or disappointed or think no one is helping - you may be the only one to have done this exact thing, and maybe others have, but don't have the numbers any more Fits the early crank perfectly.
