APR Head Studs and Head Torque Information
 

Hey I have a quick question:

Does anyone know the order in which the head studs are supposed to be torqued? Or a basic procedure as I am getting ready to assemble my motor back together and I am about to torque the head to block.

Thanks in advance

Here is what you need. Use it well.

Hey call me slow but I didn't see what I needed in there!! haha sorry man..

Does someone think they can explain a little to me an order in which these head studs are to be bolted or torqued down?

What I'm looking for is maybe like an order, for example:

2 front studs then,
2 back ones then,
middle studs...or something along those lines-or maybe it does not matter, idk.

And of course at the end they will all be tightened somewhat equally, then get torqued.

I'm new to the whole process and trying to learn as I go, If someone could help me out a little or explain that link that was posted I will greatly appreciate it.

It's the opposite of the removal order. ;) I hope you didn't just pull them out in any old order...


Here's the specific chapter for the head: http://www.cygnusx1.net/Supra/Librar...ection=EM&P=32

Sorry just figured i'd give the whole link since there is more to puting the head on than the head studs like the cam cap bolt sequence.

907mge- I am still going to use that link bro, I just wanted to see the tightening sequence as Bill UK shows. But thanks to all!

I am going to torque her down this evening!!

So I am trying to torque the heads down on the 7mgte and the ARP head studs still have a little thread over the block.

Is this a major issue?? I knew nothing about this and didnt catch it until now.

Can someone tell me if I can procede with the torqueing?!?

thanks

now from my knowledge you can but ask some other ppl i dont wanna fck ur car up ;D

If you've made sure the holes are clean (no debris inside) and you've chased the threads then you have nothing to worry about. That's the nice thing about studs, unlike head bolts you don't have to worry about the one side where the torque will be read hanging up and causing a false high reading.

Another thing, I put the head on. I tried to see if the nut and the socket I am using will fit the tunnel/hole where the studs are.

Do I have to have the cams off the head to do this job? I am new to this and am having a bit of trouble getting the nut to turn with the socket.

Any help would be greatly appreciated!!

Put head(w/o cams) in line with studs??
Torque the head down(w/o cams)??
Then put cams back on??

I installed mine with a regular socket with a wobble end extension... If you don't already have a GOOD one go buy a Craftsman socket just for this one job... having to dig out the dust from a cheap socket which exploded while torquing down using a cotton swab sucks.


EDIT: I didn't have to pull my cams, just rotate them a few times to get things out of the way.

Thanks cre,

Wow I took the cams off already man. I guess I have to look for instructions on putting them back on.

And yea my socket doesnt fit, so Iam going for one tomorrow in the am. Is it ok to leave the studs like that until tomorrow seeing they have the lube on them?

The studs will be fine..

I hope you pulled the cam's caps in the right order... :s

dude what's the order!!!

RTFM man.... :frown:




In case you've missed it: http://www.cygnusx1.net/Supra/Library/TSRM/MK3/ The ONLY reference manual to be trusted when it comes to these cars.

Hey sorry and call me slow but I cannot find the order in the manual man.

Could you point me in the right direction?

And I am pretty sure I did'nt take them off in the right order, so that being said what happends now? Are the cams messed up or whats the consequences to pulling them off in the wrong order?


Sorry I found it. Now what I need to know is what is wrong with my cams now? I am assuming that the order to put back on is the opposite of taking them off?

Thanks bill uk

So do you know if my cams are any good?? Seeing that I took them off in the wrong order.

Wow Bill, love your posts.... Wanna take over the FAQ section? ;)

Ok so when torqueing the head. Do I need to have the "TIMING BELT CASE" on the block already, before installing head? As shown below...http://www.cygnusx1.net/Media/Supra/.../EM/EM_063.gif

If it’s off already put it back on before fitting the head, but its advisable to fit No2 timing belt cover after you’ve bolted the head down, the reason being " if you skim the head, the head will sit lower down and the bottom part of No 2 timing belt cover could foul the top of the ally timing belt case (as shown in your parts image)" If that makes sense. Never been an issue with me, but I suppose if you removed a large amount from the head and used a standard gasket the bottom part of No 2 timing case cover could need trimming down.

Thanks BillUK, The motor is basically taken all apart, an I am assembleing it together. The timing belt case is off.

Your basically telling me:

Timing belt case to block,
Head to block,
Then Timing belt cover after head has been put on block
Correct?

Niice!! OK I gotcha.

Thanks a lot, my complete gasket kit will be in tomorrow. I will then put the gaskets that go to the timing belt case so I may put it on. Then Bolt head down.
