Bedding clutch in

[Brett_J]

I've seen people mention this, but I have never ever gone through a process to do it ever. I have always driven the car as normal regardless if the clutch is 15 minutes old or 200k's old, they have always lasted a fair amount of time unless they have been not rated for the power.I understand if you are using second hand pressure plates and flywheels that are unmachined it may require some bedding, but apart from that I havent ever heard of it.
People in the know please tell me if Im supposed to or is just another myth.

I purchased a 6 puck Ceramic clutch from Autoclutch this week. I was told by the bloke that a bedding in process of 750km's of easy driving with lots of gear changes should be done. Not sure if this was specific for a ceramic clutch. His reasoning behind it is that it helps the clutch grip and bite better.

I've bought several clutches from him, most custom built setup's and he has never told me to bed them in, hence my asking.

100ks of normal human city driving is plenty .

Install clutch..... Limiter burnout..... Done, Worked for me :)

Was hoping you'd reply

It wore too much off your clutch making the car lighter, thus making in more susceptible to aqua planing........

I did the same as Tyson. But more clutch kick than anything, but it must have been the rad home clutch install I did :P Still goin strong.

[Tocchi]

oh. damn.
Lol my clutch will get its first few KM on a dyno, then at drift practice.
oh well :p

+2

Install, drive to drags, skid, launch on slicks

Loves it:wiggle:

[monk_13]

never had one fail with the "skids leaving the clutch joint/in the shed" method of bedding in.

[Steppo_GT]

the day after i got mine done on the corolla a solid hour of wet laps was what i bedded mine in with. I'm on my second box but the clutch is still going strong as hell :D

[monga]

I find the shit clutches like to break. I got a button one which was rated at 300kw awhile and was easy on it for 500km and it just slipped. Twin plates (2)never fail after a 100km or so easy driving.

[ossie_21]

I got one from autoclutch as well & was told 750ks too, then to bring it back so he could have a look & make sure everything was all sweet with it. It was, then he told me to do as many skids as I liked :D

Never really noticed a difference in feel from when I got my car back to after the bedding in, but just to play it safe I'd get it working just so it knows it's role in your car :p

[DISTRBD]

Keen to pull out box n inspect it ..

[[crooks]]

jus recently got a new clutch... and was advised the same thing... drive it normal for about 750kms and constantly change gears...

doesnt work for syncros......found out the hard way at mv

Dont blame new clutch for shit gearbox ..

[iluv2moan]

was referring to bedding in syncros by means of burnouts....

[Tocchi]

my clutch (well pressure plate) failed on dyno.
no bedding in = fail lol

[Saf]

Agree. Having said that, i launch , burnouts dont do anything for clutches to bed in, they need friction and heat to get up to working temp to cut the skim on the flywheel and pressure plate.

It is the same as a brake setup. Anyone that says "do easy braking, drive gently" isnt the man you want to listen to when it comes to brakes, or frictions of any kind that mate against each other. They need cycling of heat, good launch and slip it out and then cruise about for a min to get air in there and have it circulate, and launch again.

I also BTW cut (even leave out) the inspection covers on clutch bellhousings for added cooling. Makes a massive difference , even drilling holes in it and dropping some mesh in there to stop stones.

Reminds me always of the roadbike crew .... "you need a few hundred slow kms to get the wax off the tyre" .... lmao, that tyre is now 299kms older than when it was at its peak.

[iluv2moan]

whats your tip for syncros then??

[Saf]

ATF

Every gearbox, ATF. And Synchros like piston rings or any wearing part on a engine, will "cut" or "seat", and the rest is history. Abuse will not make them seat better.

Frictions, as in dry clutches, braking systems, need hmmm ..... whats the word, corrective abuse. Rollbacks are not corrective. Wet type frictions, as found in plated diffs and auto trans, dont like heat, and are the same as synchros, rings or main bearings.

[iluv2moan]

after reading that, im still not sure how to bed them in.

i was told u have to manually bed them in - not exactly sure though

my box runs transmax z ATF fluid from factory and its in a car that wont be able to see a few 100ks of gently city driving b4 it sees the strip

I ended up doing 150 kay on the new clutch before power cuise. Then it was 3500/4000 rpm launches in the of street drag racing haha.

[Tocchi]

is it the clutch that usually fails?
or the pressure plate?

my pressure plate failed on the dyno...
it got bedded in on dyno (30mins at under 2000rpm... while Ovaboost fiddled with idle and such... so it wasnt actual intentional bedding in)
5 puck ceramic button, with machined flywheel

so would that be a case of the pressure plate not being bedded in?
or the pressure plate not being up to the task?

[lysdexia]

sounds like it was either not up to the task, of fucked from the outset i reckon matt. quite possibly the latter..

[Tocchi]

ok cool. so its definately a warranty case :)
yay

[Saf]

ok cool. so its definately a warranty case :)
yay

Perf cluthes and warranty is kinda like oil ... and water perhaps.

Its very hard to make em mix.

[SLEEKA]

ok cool. so its definately a warranty case :)
yay

on the dyno didnt it start slipping at something stupid like 160hp? you'd think at a 5puck ceramic kit would do that without sweeting, depending on clamping pressure.

in saying that, what sort of torque where you making when it slipped?

[Tocchi]

LOL well.

i had a little input shaft oil leak, and the national distributer CL**CH IND****IES (guess the *'s) said that was the reason.

i was like, oh ok, so i took it to AUTO CLUTCH to get the clutch re-buttoned, and flywheel machined.
he tested the pressure plate... it was a stock one. not even heavy duty. CI hell scammed me there.
so im getting 25% more clamp put on

[DISTRBD]

Was there oil on the plate ?

[Tocchi]

yeh a little bit of residue. im getting a T5 seal kit this arvo :)

[DISTRBD]

Sounds like they just used as excuse , had some with oil dripping of them before they slip ..

My 3 major clutch suppliers wont warrant ANY performance clutch and what they do warrant they dont pay for labour just replace item :( :( :(

Cant see oil on there , shit pressure plate .. and to think i juststarted dealing with Clutch Industries for heavy duty kits :( might rethink that idea

[Skitzo]

Autoclutch are winners. I highly reccomend them. not that i have done much driving with my new clutch from them. But top bloke and keen to help out.

yeh re-consider it. i really would.

yep. he's very helpful and his turnaround is fast as.
he's probably the Ford owner that wanted to covert his 6spd turbo falcon to 5spd lol

[DISTRBD]

Dont like P/P that been welded back together , weld breaks away n buzz saw spec :uhh:

[Tocchi]

what? on CI clutches?

[DISTRBD]

Fitted ya new P/P yet Tocchi ? if not got a pic of it

[Tocchi]

nah, Auto Clutch will have it ready on Monday
