What if, Why and How? Various Qs

[mocchi]

Q: Why do piston #1 needs to be set @TDC while changing timing belt?
If I change the timing belt without moving camgear/crankshaft then it should be fine? plus theres woodruff key in crankshaft pulley.
A: ?

Q: What if pilot bearing in flywheel is loose?.
tried fitting a new flywheel. the pilot bearing sits flush in the flywheel but i can spin the whole pilot bearing in the flywheel (not talking abt the inner race, but the whole bearing spinning). its not tight like oem.
can this be a problem? service manual doesn't say anything about this..
A: after leaving it for a day, its gone tight now... lol maybe cos its hotter today.

ps. can be moved to noob section if this is inappropriate technical question.

[bennjamin]

it needs to be soild and firm in the flywheel . It is TAPPED in with a socket piece or oft hammer - it cant be loose. It means you have the incorrect sized bearing.

[mocchi]

forgot to say, in the flywheel, there is a ridge where it holds the pilot bearing from slipping to the other end.

how tight?
i have to use hammer to push it in, but i can take it out with my index.

the pilot bearing comes with the clutch kit i bought.

btw, how heavy is oem ek d16y4 flywheel anyway?

thanks

[bennjamin]

yup i know there is a ridge - I cant say the proper OD of the pilot bearing for all D series. But the standard flywheel would be heavy. Like 8-9kgs probably

[mocchi]

... damn it. fkn ebay shiet. the ad says "much greater weight reduction over oem flywheel" my ass.

its weighs exactly the same then if its 8-9kg. i thought the old one was already light flywheel.

back to original question.. would the 'not too tight, not too loose' pilot bearing in the flywheel produce problem?

thanks ben. fast help.

[bennjamin]

not sure dude sorry. but a "lightweight" flywheel is about 3.9 to 4.5kgs or so (both D and B series). Standard is around double that.
As for the pilot ,its possible the flywheel is slightly larger than standard (dam ebay stuff) i doubt the bearing is slightly off. Check with your OLD flywheel that the new pilot bearing fits. No need to tap it all teh way in , just place it flat with your fingers , if it wont go in at all or just catch the lip its fine.

[mocchi]

so the ID should be the same like oem one yeah?

[bennjamin]

ID = for inputshaft spline
OD = for flywheel mounting....
so yes the OD (outer diameter) should be the same as the old pilot bearing off your old flywheel.

[mocchi]

eh? why would the od matter? to make sure that its just the flywheel that might be slightly bigger?

[bennjamin]

*slaps* lol
The OD is the problem. You stated it is loose ( the OD is alittle loose) yeah? I want you to compare both the ID and OD of the new pilot bearing , on the OLD flywheel. See if its the same as the old flywheel and old pilot. If it is , you know the flywheel possibly has a manufacturing defect. Or requires a bearing with a tiny bit bigger OD

[mocchi]

oh haha.. yeah i will post it soon. thanks ben hehe :D

[TODA AU]

Are you using a new 6002 bearing?

[mocchi]

ID: 1.5mm
OD: 3.4mm

both old and new are the same.. old is japan made, new is china made. soon... EVERYthing will be made in... ?

@TODA AU, will confirm tomorrow. just got back home :|

[bennjamin]

did you measure with a proper veneer caliper ? or just a tape measure ?

if the pilots are the same , you can assume the flywheel is slightly larger ID (for the pilot). Rectify by a larger OD'd pilot bearing or perhaps get another one/trade/refund

[mocchi]

use ruler lol the steel one.

[bennjamin]

not accurate enough. Grab a veneer caliper and measure the exact ID and OD of both dude. You could be .5-1mm out

[mocchi]

hmm. dont have one, i guess i gotta buy one. the plastic one will do the job just fine eh?
no need to buy sumitomo ones or something high quality like that..

[bennjamin]

yeah a plastic one from supercheap is fine. more accurate than using your thumb lol.
grab it from supercheap auto etc - or even take it to a local mech they should have one to borrow

[mocchi]

okie dokie benjie, thanks heaps for your help.
ill give you an invite if you want :D

[Slaz]

That ebay flywheel looks like it will be upsetting you tomorrow! :p

[mocchi]

That ebay flywheel looks like it will be upsetting you tomorrow! :p

they even advertise the flywheel as exedy flywheel, but cant see any exedy engraving or part number watsoever on the damned flywheel :(

im gonna give neg feedback harrrrrrr!!

[bennjamin]

i think its probably a metal cast of an OEM flywheel , with a few extra holes drilled in it. Hence the problems with workmanship.

It pays to buy known japanese and US parts imo

[mocchi]

it was advertised as exedy flywheell!! i thought i was getting branded flywheel!! LOL i got jibbed!!
T___T" so sad... damn uncle sam.. so so sad... (http://www.youtube.com/watch?v=AE1OUF6Mrdk&feature=PlayList&p=AE88DC1A81A28665&playnext=1&index=8)

Cmon Oscar, we all know you love a bargin! :p

[mocchi]

@TODA AU: yeah the pilot bearing is 6002RS, made in china.
care to share your thoughts?

[TODA AU]

Get a vernier & check the dimensions.
http://www.thebigbearingstore.com/images/InitialSet/SINGLERADIALDRAW.bmp
A = 15mm
B = 32mm
C = 9mm

Then check the ID of the flywheel, it should also be 32mm for a light press fit.
(So 31.95mm to 31.98mm is good)

[u mad?]
