Input shaft bearing problems....
 

Ok so I have the transmission out of a 86 5-speed. I have replaced the pilot bearing, which was completely gone with not even a single piece to show that it was ever there, the pilot bearing seal, which was also evaporated, throw out bearing and also got the input shaft bearing.

Problem is that they didn't give me any seals for the input shaft bearing and I cannot get them at any local place in town. Does anyone know the part number for the seals so that I can call around and get them. I have been working on this transmission for days now. I thought the pilot bearing and throw out bearing where making the noises from the transmission but after I replaced them and got the transmission in and filled the transmission was worse.

Before the pilot bearing and throw out bearing the car would whine and and once in a while the clutch would lose pressure and the transmission would should like something was about to come through the case.

After the pilot bearing and throw out bearing the clutch is great but any time you hit the gas it bogs down 200-500 rpm and sounds like something is very loose in the transmission and then the rpms will go up and it will sound fine. The whining is still there though.

Am I right that I need to replace the input shaft bearing or is the tranny fried....??

Also it whines in every gear but 4th....

Have you checked the transmission fluid condition and level?

......... You did read that I installed a new pilot bearing, pilot bearing seal, and throw out bearing.

The problem is the seals for the input shaft bearing.....

So anyone have that part number???

I found this part number but it brings up a bearing way smaller at advanced so I am unsure if the part number is correct. The part number is 0603-16-103

I think you have some different problems
A worn Gearbox won’t make the engine bog down
If the whining is there because you need to replace all the bearings in the Box
As you have started the job you need to do it all

that's the front seal for the transmission

I have read on the site that the whining in the transmission is usually the input shaft bearing. Are you saying this is wrong and that I should disregard the search function entirely because of it giving me the wrong information???

I need to know what to do because my car has been taking up a garage bay and is costing me about 100 bux a day that it sits there....

Advance already screwed me over because they didn't tell me I needed the seal so that is 100 more that I wouldn't have had to pay. I am already up to 500 because the shop can't work on it until the parts get in and also they are unsure if they can even get the bearing out. Do you have any idea's on how to remove that? The garage is unsure if they will be able to get it out with any pullers they have. Do I need to take the transmission to a shop to have the input shaft bearing replaced.

Also the garage has called around and tried to find the front cover gasket but no shop around here carries it. What kind of other materials can I use to make a gasket for that???

I am not saying the post your reading is not correct
What I am saying is have the box overhauled with a specialist as it will be cheaper in the long run
Why are they charging you for the ramp? Can’t they take it off and then put it back on when the box is ready?

The transmission and drivetrain will be replaced completely within 5 years so I am just trying to fix it to the point that it will last that long. In 5 years the entire car will be stripped, painted, rebuilt, and modded. I am mainly just wanting the whining to go away and I think the bogging down that happens is because the transmission did not have a pilot bearing for at least a year. In that year around 5k miles were put on the car.

I would need to pay a garage around 1300+ to rebuild the tranny in my area.

Due to the pilot bearing being non existent is it possible that it wore the input shaft bearing so that it it wore the front bearing so that it whined???

(yes as it was wobbling around and punting presser on the shaft hence the bearing being bugged
there should be a No on the bearing and you should be able to get it local and also you should get a seal as well
in the UK we would get one over night

I did get a bearing but the local auto parts store was unable to get a seal. I had to order one about an hour away and getting it tomorrow.

I am also taking the transmission to a transmission shop tomorrow to see if they can replace the input shaft bearing so that we can put the transmission in the car tomorrow and get the car out of the bay so that other work can be done.

Unfortunately I only have 1 seal because I could not find any information on if the bearings are lubed internally by the transmission fluid or if you have to have a seal on each side and pack the bearing with grease. Hopefully it is the first but if it is the second I can have the shop put the bearing in with the seal on the inside...

Thanks for the help btw. If the transmission still whines I guess I will be putting in a s5 transmission....

Quick question....

I did not think the input shaft bearing would need to be changed so I never ordered a front cover gasket...

Can I use permatex or should I order one and just wait for it???

i would just use instant gasket i assume you call it permatex
but we have sheets of Gasket paper so we can make them
but as you need it on the road and it is being refurbed later just go with what you have

check the transmission mounts, the center mount(unservicable) usually deteriorates and the transmission sags down and sits on the metal crossmember which transmits all the transmission noise into the cabin. new puck mounts help, for a period of time.

Guess I am lucky that I have access to one of the center ones that is used but not completely deteriorated. Taking the transmission to a shop tomarrow to have the main shaft bearing and counter-shaft bearings pulled and hopefully installed as well. Will let you guys know how it goes....

Also for some reason my transmission goes in very easily..... like just jack it up and move it forward.... Either my engine mounts are going and that makes the engine sit back farther than normal or my transmission just likes me....

I am going with the engine mounts on that one though lol. :P

Permatex is a silicon gasket maker. Unfortunately where I live the different gaskets are either unavailable or I have to wait 3+ days to get :S

Also Karack, Nice site btw. Who designed it???

i threw it together in a couple hours myself one evening, i still have some redesigning to do on some of the pages though but thank you, i have no webdesign experience so i really take that as a compliment. :)

OK so paid a shop 50 bux to replace the main shaft bearing. They couldn't replace the counter shaft bearing without taking the entire transmission apart so I said the main shaft bearing would be fine. I get it home and put it in and still the same thing.

The engine still has the noise so I am assuming that the transmission needs to be rebuilt. I am going to go get my s5 transmission and since the rx7 that needs the transmission is street ported the additional horsepower should make it so it doesn't slow it down too much due to the different gearing ratio...

Anyone have any info on how to wire up the s5 tranny so that backup lights work or should I just swap out the reverse/ 5th gear switch from the s4 since it is already wired for it???

Also will the s5 hold up better???

any word on if the 5th/reverse switch from a s4 transmission will work in a s5 transmission???

Oh also was coming back to my house from getting my transmission and my car started stumbling while I was driving. Ended up taking me 2 1/2 hours to go miles because it was stumbling so bad. Did a compression check and the engine is fine. I am thinking that I have water in the engine which is giving me a check engine light every so often. Problem with checking the codes is that my emissions weren't eliminated correctly so it takes me like 20 mins to get my codes. Anyone know if water in your tank will put your CEL light on and also make the can stumble when driving???

Also it doesn't stumble when sitting level. It only does it on hills....

There is a check valve in the fuel line that is supposed to shut off fuel to the engine when the car flips over. Maybe it's bad?

try pulling up on the shifter while the clutch is out and the tranny is idling and see if the noise changes tone or goes away, this indicates worn tranny mounts.

Would it be able to activate and deactivate if it is bad or just shut off the fuel and keep it shut off???

I am thinking water because now that the tank is down to 1/4 it is starting to do it while you are on flat ground. Still hasn't started to do it while idling though....

the rollover valve keeps the gas in the TANK when the car flips over, it doesn't do anything to fuel supply to the engine.

check all your general tune up items like fuel filter, spark plugs and plug wires. if everything is fine check the catalytic converters, "reeding" sounds can come from the exhaust system when the exhaust is restricted (the same as when you used to blow grass as a kid) which can cause transmission misdiagnosis.

goto a mazda dealership and just go into their parts store and order one.
