Machining the flywheel on clutch replacement ???

[kraiye]

Hi all,
My friend took her '90 barina in to ultratune (thats where it broke down, lol) to get a new clutch and the guy said u'r supposed to machine the flywheel when replacing the clutch as this makes it last longer. I haven't heard of this before and was wondering if it's really necessary?
She plans to keep the car for maybe 2 more years.
Cheers.

Yes, its a good idea to machine the Fly at the same time. :thumbsup:

Depends on inspection and how long the old clutch has been there.

The Fly will be worn from the old plate. Machining the Fly flat will match it to the new plate.

[destrukshn]

yes.
definately machine the flywheel, as it may ahve a uneven surface, and may damge your new clutch.

sweet
wil giv the go ahead
thanks guys :thumbsup:

[destrukshn]

only a extra $30 or $40 isn't it?

[kraiye]

dunno. i didnt ask 'cause he knocked about $150 off the price seemingly simply 'cause I rang up.
if i get to see the receipt i'll update

Should be pretty cheap, here we do it for like $20USD so $40AUD sounds about right. If there are cracks or dark spots defiantly get it machined, if not, you're more than likely to be ok not getting it done. It's still a good idea though. Also just like brake rotors do not touch the surface when you go to assemble it, the oil can damage the pads and cause slipping. Make sure to use some brake cleaner and clean the flywheel before placing the clutch plate on.

Remember to change the small bearing as well. (Inside the flywheel)

spigot bearing.

Thanks for info.


spigot bearing.

cool i'll have to remember that when i go to do my clutch. her car is getting done at ultratune.
anyone seen a clutch DIY floating around?

[JasonGilholme]

Theres a tranny removal DIY that wyn did.

Very detailed. Definately possible for the experienced DIY'er. Aligning the clutch is the hard part tho. It doesn't just bolt up all nice and dandy unfortuantely.

I have just finished doing a DIY clutch replacement, and yes you need the clutch aligning tool. The hardest part of the whole job was getting the gearbox back into place and aligning the bolt holes. It took about 3 hours by myself to get the gearbox back in, all lined up and bolted back together.

[kraiye]

linkage?
;)
i wanna do a tranny swap down the track so this will be dam usefull

[muhhan]

Is transmission removal and clutch/fly replacement possible to do on jack stands? Or do you need a hoist/bend pak?

Will definitely get the tools. Saving on the labour for install so why not spend it on the tools to do the job right!

[destrukshn]

yeah you can do on jack stands.

An OLD trick to get the transmission lined up is to get some bolts the same size as the transmission bolts but a little longer say 1/2 inch.

Use two of the and cut the bolt heads off and then cut a screwdriver sized slot into the bolt where the heads used to be.

Screw the now headless bolts like studs into the block finger tight and then line the transmission up on the studs sticking out of the block and slide the transmission now on the studs that are taking the weight of the transmission and it SHOULD go right in maybe with a little wiggling.

Put one of the old bolts into a hole and get it semi tight then unscrew one of the studs and replace it with a good bolt and then the other stud and other remaining bolts. If you can't get the studs out by hand that's what the slot is for just use a screwdriver to get it out.

The threads on our honda blocks are really long; conveniently similar in size to the length of the spline on the input shaft.

Just need to get it "close" and get a two bolts threaded then just tighten the bastard.

I thought it was going to be a nightmare doing mine on my own but took about 5 minutes. 3 hours.. you poor thing haha

Edit: It will be MUCH more difficult to put the gearbox back on with the engine in the car. Any time I need to do gearbox work, or similar, the engine comes out; saves a lot of headache in the end.

[JasonGilholme]

I've never done it but from reading a few tutorials it seems pretty straight forward. Hard in places, but thats to be expected.

Nothin that can't be DIY'd!

Yeah, Jackstands + engine still in car = 3 hours, but I did buy the longer bolts to get the gearbox in when it was close. The drama I had was getting the gearbox back under the car while on the jack, and when it didn't fit, having to lift up the gearbox and then slide the jack under. Quite awkward by ones self.
