ok, i did get told but forgot
instead of angle tightening, there torqued up

anyone got the whole sequence of torque
i take it i keep the same paturn
area 52 helped with this. but i've had that much on my mind, this way i wont forget

 

anyone.

 

Here is the advice I was given with mine - standard size BTW

When putting in the studs, use the factory numerical order but use these torque values. First round go to 20ft lbs. Do this about 2-3 times to make sure the head is seated down. Then increase in values of 20ft lbs up to 80. AFter the final round of 80, let them sit for an hour then do it again at 80. Also, when putting the studs in the block, tighten them down as much as you can with an allen wrench. DO NOT FOLLOW ARP RECOMMENDATION OF HAND TIGHT. This is not correct.

 

Tightening to a torque figure will not be hindered by hand tightening, but tightening with a allen wrench could end up with the studs over tightened initially. IMO please elaborate further, thanks Steve

 

thanks mate,

so its 20ftlb, then 40/60 then the final is 80
the middle 2 should be a little tighter.

 

this is what i got, so changing the settings for arp:

(1) Apply a coat of engine oil to washers and
bolt threads.

(2) Tighten all bolts to 29 N•m (3.0 kgf-m, 22 ftlb)
in alphabetical sequence.

Then tighten all bolts to 69 N•m (7.0 kgf-m, 51 ftlb)
in alphabetical sequence.

(3) Back off all bolts by 180° first; back them off
by 180° again.

(4) Tighten bolts (A) and (B) to 34 N•m (3.5 kgfm,
25 ft-lb).

(5) Tighten bolts (C), (D), (E) and (F) to 15 N•m
(1.5 kgf-m, 11 ft-lb).

(6) Tighten all bolts by 80 to 90° in alphabetical sequence.
CAUTION:
Do not tighten bolts more than 90°.
(7) Further tighten all bolts by 80 to 90° in alphabetical
sequence.

CAUTION:
Ensure that the total “re-tightening angle” [in
the two previous steps] do not exceed 180°.

just want to make sure every thing is right

 

Just passing on the advice I got from Ron at Axis when building my 2.33.

 

I don't doubt what you were told but having seen some of the mechanics I work with. They can be heavy handed and don't have the finesse required at times. I like to understand things fully before making any judgement and everybody has their own experiences.

 

yep agrea, thats why i posted this up.
just to make sure, i know the list i put up works perfect with the normal bolts

but arp studs are a little pricey to damage
i just want to make 100% sure before i go ahead and build my engine

 

You won't damage the studs, it's the heads you have to worry about.

 

That looks like the procedure for Subaru torque to yield stretch bolts, not ARP studs - so don't follow it.
I used torque steps up to 80/85 lbft for 11mm AP studs.
They were wound into the block until just touching bottom with an allen key and then rotated back by 180 deg.
Lubricate everything with the ARP lube or 10/30W oil.

 

they are for standard bolts mate.but also shows the cycle to which you tighten.

just put it up to see if its the same, but the torque settings for the arp.

 

well i read the instructions, but they say follow the normal sequence. but not to torque more than 85ftlb

but the centre ones are always torque slightly higher
unless i put say 80ftlb on the end ones, andthe centres 85ftlb
i've always used the standard bolts. used arp once, but the instructions gave every thing then.

the heads will be going on tomorrow, so need this advice asap

 

well, to day i put the engine together
did all that was on the subaru disk, except i did a another angle tightening of 45'
the 2 middle bolts came to the 85nm too after doing this

i dont think there will be any issues with the amount of torque i put through them.
only time will tell

 

85 Nm or lbft? If Nm then they need tightening up some more.
Thought there was enough replies to say you don't need to do any angled torquing with studs?
Just keep with the pattern that Subaru describe but do them all at something like 20 then up to 40 to 60 and then to 85 lbft.

 

only just seen this. it was ftlb sorry.
the reason i angle tightened the bolts is tohelp sit them.
but in the end, i tightened than the same as the normal bolts, but an exstra 45' sequence

ran the engine, and all seems fine.
mapping tomorrow.
only time will tell

 

Sorry to resurrect buthow did the engine hold with these torque settings?
