Clutch Replaced
 

I had my clutch replaced today by Toyota and after I picked it up and drove it home I noticed a few things I wasn't used to. I'm not sure if what I am going to describe is normal operation after a clutch replacement or something I should be concerned about...

When I shift into different gears I can hear and feel the gears changing as I shift. Specifically, below my right forearm as I shift I kept feeling a faint noise like something was hitting the armrest underneath my arm. I had never felt or heard anything prior to the replacement and prior to repair it was smooth shifting through all gears. Do I need to allow the car to go through a break-in period?

Also, as the car was idling the RPMS would bounce from the idle point of 600 RPMS then up to 7-800 RPMs and then dip down to 480 RPMS and back to 600 RPMS every 15 seconds or so - the AC was on. When I have the AC off it holds at 600 RPMS which is normal from previous operation. The RPM fluctuations would happen every now and again before when my AC was on, but it has me concerned as I just picked up the car up and I'm experiencing these different things.

Should I give it a fee days for the car to adjust to the new clutch? I'm not tech savy enough to know if that has anything to do with it, but any feedback is appreciated.

The car has about 53500 miles - 2013.

Thanks.

When doing a clutch job they typically drain the trans fluid and refill it after. Changing it from factory fill changes the shift feel and gearbox sound, maybe because it's a bit slicker.

RPM fluctuations are normal even if A/C isn't on it will fluctuate if you roll both windows down for instance.

Oh, I'd give it a few miles for the car to get used to the new clutch and for you to get used to the new clutch.

Why do you figure your old clutch went out .. ?? Boosted, tracked, new driver, don't know ....??

Why do they do that..?? Just curious.

500 mile break in period on any new clutch that ive ever seen. Its normal to smell a little burn on the initial few miles. Its gonna be a lot more notchy shifting especially is they used some rlly gewd trans fluids. Also Rpms sound normal for me with the AC on. Try cranking the ac fan to full with the temp on lo and see if it dips alot less. Not sure what if any sensor has to be removed when doing the job but I know i had a clutch job on a FWD car that has some sensors removed and they forgot to hook one back up. That threw a CEL though so its probably nothing to worry about.

I hope this is a serious question and ur not trollin because im about to answer it lol. The drive shaft has to come out first so trans fluid will pour out of that end and then you got a mess.

One of the throwout bearings went and it happened to be covered under warranty. They said it wouldn't be a bad idea to just replace the entire clutch since everything has to come out just to replace the bearings. I said why not and all I paid for was parts instead of getting charged $1500 with labor all I paid was $587 including tax.

Man, they did you a solid. Some people here are being told the TOB is a wear item. :/

Just curious as to what happens when the tob fails

They don't go all at once. First they get noisy and if you're in tune with it, you'll feel it rumble in the pedal.

They screech when they start seizing. Don't wait that long.

I have determined my idle noise is the flywheel chattering because it goes away when car heats up or clutch pedal is depressed. Guess if something brakes we will know then LOL

Oh,.... well, I'll be darned ........ ol @tofurun learnt me something today ......:thumbsup:

I didn't realize the tail shaft had to come out of the transmission on the FR-S.

I'm stuck in the 50's again ...... :sigh: We used to take apart the universal joint and then drop the driveshaft. Or, at least I did ...... yep, those "C" clips were a butch to get off of the universal joint without messing them up ..... :mad0259:

Thanks again fer the edumacation. I'm going to add you to my consulting staff, along with @Ultramaroon.

No, that's called "neutral rollover." It's the freewheeling gears rattling around in the transmission. Nothing to worry about. I've driven/worked on many friends' 86s. They all do it.

Stock lube does a better job of hiding it at the expense of being tougher to shift when cold.

When did I get promoted? You said it was an unpaid internship.

Yea I noticed it after one piece drive shaft and stupid expensive motul fluid.

:bellyroll:It's a lot easier to just unbolt the 4 bolts in the rear of drive shaft lol. Idk nothing about 50s cars lol I thought they drove Fred flintstone cars back in your day. This position I get a monthly r&d stipend?

Just now ...... by @tofurun being added ...... that bumped you up a level .....:D


humfrz

Output shaft of the trans used to look more like the input of the diff. Unbolt both ends.

Actually, my automotive expertise is/was with the 1930s and 1940s cars and trucks.

I started losing out in the 50s, when they came out with automatic transmissions and fuel injection and fancy stuff like that ...... :sigh:

No, your position is the unpaid intern position that @Ultramaroon got bumped up from........:)


humfrz

Apparently, their are two bearings? Forgive me for my lack of knowledge.

Anyways, the one that went was covered and wasn't considered to them as a "wear" item, but the other one was so I was going to have to pay $36 for it. I could of been fine just replacing the 2 throw outs for another 15-20k or longer per the dealer, but as I said, paying what I paid for a new clutch and not getting charged the labor due to that one bearing being covered I felt was a decent deal.

I just hope I can get used to the new feel of the shifting through gears.

Also... Is there a way for me to adjust the catch point of the clutch? It seems I have to let the pedal out further before it catches.

My mechanic was the one that told me that. Maybe he changes the fluid out because it's a good practice anyway. Or maybe some subaru wrx gearboxes will leak out a bit at the seal when you remove the driveshaft, and he doesn't want to get smelly transmission fluid all over his clothes and his shop.

Yes and this is a pretty important adjustment to make after a clutch install.

Here's the DIY guide for easy clutch grab adjustment: http://www.ft86club.com/forums/showthread.php?t=8040

I'd take it to a shop to do the adjustment if you don't know what you're doing. A good tuner / installer shop can get that done for you.

How about those torque-tube Ford drivelines?:mad0260:

Actually, there is only one TOB (Throw Out Bearing) or release bearing per car .....;)


humfrz

Forgiven. :thumbsup:

There's a heluva lot more that we all don't know than what we do. Some of the folks here are amazing experts. I'm not one.

I never had one of those apart ...... I was a chevy man ...... :D


humfrz

Amen to that!

This thread is so civil.... where did all the angry board members go??? I think i need to subscribe to more discussion that Tcoat and humfrz participate in...

@Ben_G I have a theory that @Tcoat and @humfrz are really just forum AI built to pacify us with stories about the moon landings

LOL Check through and find a thread where some dumbass pissed me off though!

Hum, not so much.




They landed where????????

Ya, I reckon the topic of "clutches" doesn't bring out the bad in us ...... :iono:


humfrz

I ain't got no beef with clutches.

Another thing I have noticed since I had my clutch replaced is when I turn my key two times before I turn the engine on I noticed my RPM needle doesn't move anymore. It used to go up to 7500 RPMs or so then come back down. Was my rev indicator turned off or something?

They may have disconnected the battery during the install which would cause you to lose that information IIRC.

Yep, just re-set it (refer to the drivers manual).


humfrz

I think something is wrong...

Yesterday when I was driving it sounded like a piece of metal fell out of the bottom of the car. Now it's making these noises on top of the issues I was having before. I already called Toyota and I'm bringing it back in tomorrow.

Based on the videos below what do you guys think?

Please help.

Well, darn, StOpNGOx ....... that's a shame you are having such a go around with your car's clutch ...... :(

Yep, it does sound a bit like a thrashing machine!

I think it is beyond .....newness, gear rollover, flywheel chatter or a bad TOB.

It does sound like something is lose fer sure .......... damn, it could be several things, none of which are "normal".

I wouldn't drive it too far until you can get it back to the dealer.

Then again, maybe they just didn't tighten up one of those underneath panels and it flapping around.....??

I hope you (or they) can get it sorted out soon.


humfrz

Wow, something came loose under that bell housing. Second clip shows that.

The third clip sounds like the driveshaft is rubbing against something.

I'll let you know what those clowns at Toyota say tomorrow. If they begin to tell me this is normal I'll lose it on them.
