Unknown rattling noise

[4piknup]

Only way to know is to pull the box to inspect. Usable inspection plates were stopped at the same time mitsubishi phased out the hemi.

Its only a few hrs work and there is about a dozen of guys here that have thrown springs out of plates.
And the plate slips, so something needs doing to it.

I dunno how many clutches your dad has seen, but between briano, jamo, dougmo, khubno, geo, and all the other guys here that cant be assed helping a knowall out, there is probably easy 500 clutches seen and changed.

I will put a stubby on it, there is a problem inside your bellhousing that will only be revealed with gearbox removal.
A second stubby on, that if gearbox had been removed earlier, damage would have been less.

Just seperately tho, have you got the backwards bolt fitted, it is below starter and bolts engine to gearbox.
It wont fix your problem if its there or not, but it is important and needs to be fitted.

Also as brian said, if your clutch is dragging and its baulking between shifts you are destroying synchroes. Those rings are expensive and even dearer to replace than clutches. And you still need to pull the box to fit them

Dont think you are cool and can shift perfectly without the clutch. You are wrecking the box by doing it

Yeh, the slipping needs to be addressed, I agree. And in regards to how you all think the same thing, I know, you guys have been fiddling with these things for far longer than either me or my dad have, I do value your opinions and it's great having a whole bunch of people who know the ins and outs of these things

Sorry, can't take that bet, can't buy stubbies

The backwards bolt, can't recall which bolt exactly your referring to, but the long ones that go through the transfer case are in, and the bracket under the engine is there, pretty sure we didn't miss any bolts, but it won't hurt to check.

Funnily enough it shifts fine and doesn't crunch at all, but It probably isn't fully disengaging like you said, lucky I put redline MT-90 in it, that stuff is worth its weight in gold when it comes to keeping nice shifts.

The above sums it up perfectly for me....but hey...just listen to your Dad mate. We have told you what needs doing. If you choose to just ignore that and keep driving...lets hope your Dad has deep pockets and knows how to fix bigger problems...as we probably wont want to know about it after this thread. Just sayin.

 

[4piknup]

We will want pics regardless.

 

[evo-gsr]

Of his Dad, Jack ?

 

[BMGTZ]

get Dad it the car and go for a drive....find a long hill and drive up in third or fourth while having foot flat. if it slips....its fucked.

 

[khubner1]

Lol Brian when I fried my clutch I didn't need a hill to make it slip just a 3rd gear pull onto boost was enough

 

[3VOLUTIONIST]

Yeh it slips in any gear except first when it boosts above 10 pounds. Which tells me it's pretty stuffed

 

[4piknup]

Mrs friends car couldnt get up my driveway. And I can push a car up there by myself. And im only little.

so what is the issue with changing the plate out?

so what is the issue with changing the plate out?

No issue, pulled the box off this evening. The clutch still has all its springs, although admittedly the long ones are very loose (can be rotated in place) the short ones a firm though, but you can see where they have been wearing against the metal where they sit, possibly causing the shuddering? unsure.

The slipping seems to be the result of crap machining of the flywheel, the outside edge is all shiny and burnt in places because the clutch has only been gripping the outside ten mil of the flywheel, the rest still looks machined and hasn't been touched even after nearly a thousand kilometres. So it looks like I'll put my original flywheel on that was running on the old engine, or have it machined if I buy a new clutch and pressure plate assembly, which I mays well do now it's all disassembled.

Pictures to follow

[4piknup]

Thats good. You had to have a look.

 

[4piknup]

I just looked where you live. Balcatta.
Take all of it to brakebonders in malaga, tell them it slips and shudders. They can test your pressure plate, and sort you out.

Idk why it only catching on the edge of clutch plate. Its like the plate was backward but I know it wont go on at all, and if it did it wouldnt change gears either.
Funny marks on the spring too?

BrakeBonders? Havent heard of them, will have a look, thanks
Will take the flywheel down to HeadTorque in ozzy park tomorrow, dad knows the guy who runs the place, he can check the flywheel apparently, tell me if it's been machined poorly or if the flywheel has a bow in it, if the flywheel is out of balance that might explain the shuddering, it did feel like i had an oval shaped flywheel

I think its only gripping the outside edge simply because it wasn't machined flat, but I guess I'll find out soon enough, just glad it wasn't as bad as it could've been

 

[4piknup]

Just put any straight edge on it. I can see from the reflections on the 2nd and 3rd pics that it looks flat.

Brake bonders are awesome. Used to do our crane clutches and brakes (still do but I changed companies). Then they have done a bit of car/4wd stuff for me. Not sure if they do sintered bronze paddle plates or not, certainly do organic stuff. If you give them the bits, they dont pull boxes out but you have that under control.
The height of the step on the flywheel is pretty important.

Are you night shift too? Im on last night shift now, back to normal in a day or so.

 

[khubner1]

Yeah make sure the step on the fly gets done aswell the step depth is in the manual

 

[3VOLUTIONIST]

Not night shift, just student shift

 

[DOUGMO]

it looks like the step has been done but as the others have pointed out make sure the height is correct. it may also be coned a bit hence the wear on the outside only
