ARP headstud installation...How???

[weissguy]

I'm at the point of my build where I need to put the ARP headstuds into my s14 sr20det. This will be a first for me and the search yielded absolutely no results so here I am.


How do I install these into the block?

[n240sxfnatic]

RE-Search, and follow the arp instructions

[s14unimog]

Its called an Hex Key..... Are you sure you should be doing this?

If they don't break free with a little bit of effort, smack the top of the stud with a metal hammer. DON'T fuck up the treads and don't beat it down into your block. Sometimes they stick due to the difference in materials so a little shock will free them up.

[weissguy]

Maybe you should come over and do it for me s14unimog...right.

Missing instructions so I'll get them from their website.

[s14unimog]

I've got to poke fun a little, come on....

At least I gave you some good advice

[Walperstyle]

Install them after you put your valve cover back on

[Z33dori]

put some teflon tape on the ned.... and screw it into the block...

[weissguy]

well they're in now. I guess more than anything I was wondering what the procedure was...do I put on the moly assembly lube onto the end that goes into the block, do I put the head on first then the studs etc...

[Z33dori]

i put the lube on the ends that you attach the nuts, and put teflon tap on the block ends.

1st. put on you head gasket
2nd. put in the 2 middle studs, the longest 2
3rd. put on the head
4th. install the rest of the studs
5th. begin the torque down process

[weissguy]

Thanks z33 I'm going to take out all of them except the middles since that will make it easier to get the head on...All of my studs are the same length though.

[Z33dori]

there should be 2 that are a lil longer when you lay them all on the ground.

[n240sxfnatic]

no their arent, just the middle two stick out a bit farther then the rest.

Install studs using ARP moly lube, then thread them in w/ a 3/16 allen, torque to 70 ftlbs.

[weissguy]

My instructions that came with the head studs say to torque them down to 105 ft lbs in 3 different increments as per fsm pattern.

105? is that right?

[Sileighty_85]

well my Instructions tells me Torque nuts to 70Ftlbs with ARP Moly Lube Or 85ftlbs with 30wt

also Due to expansion rate of aluminum it is recommended that the torque should be 65 ft lbs with ARP Moly Lube

I torqued mine to 68ft lbs with the Moly Lube
No problems after 2 years

[Z33dori]

i trq'd mine 3 times

30ft/lbs
85ft/lbs
110ft/lbs

some where around there

Thats sounds right ^

[Sileighty_85]

where are ya'll getting 110 ft lbs from?

[n240sxfnatic]

110 is wrong, Its to tight. Its 20, loosen, 40, loosen, 60, loosen, and finally 80. This is with arp moly lube. Thats what my arp instructions said.

[weissguy]

I'm going to scan in the directions that came with the head studs tomorrow. It says sr20det right at the top of the sheet.

[KA-T_240]

Why are you scanning the instructions. That is what you NEED to fallow.
I also highly recommend using the ARP molylube over motor oil(what ever else u may use, especially Teflon tape).

[weissguy]

Scan as in scan them into a scanner and upload them to the computer. I'm definitely using the Molylube that it came with and I have no plans of using teflon tape.

[Z33dori]

i didn't have instructions...

i went by DSM/srt4 trq specs.....

but yea i forget you do need to loosen them in between each trq.

why would you go by the torque instructions made for a different motor. arp designs each kit to be used in the specific application. the stud length, size, grip length, and in some cases even the stud material varies. the bolt is made for the specific application to be torques to a specific level. if you over torque it then you may pass the yield point of the stud and put in in plastic deformation range. after that the strain will keep increasing without much of an increase in clamping load, thus resulting in diminishing returns.

use moly lube and torque to what arp specifies :)

[Z33dori]

pretty sure these studs are for a Jetta anyways

so i don't see a problem ...

[4sfed180]

so what if they are arp studs made for a VW engine. ive worked at an engine shop and all we did was VW superV, US F3, and offroad VW motors. you dont torque those to 110lbs anyways...

"seeing the problem", understanding why things are done one way or another, or reading forums are not all the same... :)

[fromxtor]

Mine came w/ the same sheet Sileighty_85 posted up

[moses]

I just got my arp head studs in and this is what they say

You can see it says sr20det on the top and the bottom says 3 equal times to 105ft lbs. WTF

Those must have new instructions cause I did mine a year ago and it was the way I listed above.

[moses]

Just to make 100% sure. I am torquing the hex head and not the nut right?

stop right now and go back in time and kick your father in the balls before he gets ypur mother pregnant and you grow up to ruin a sr block.

[fromxtor]

1.Apply ARP moly lube to the non hex head of the studs threads
2.Thread studs into block w/ 3/16 allen wrench, till they bottom out.
3.Apply ARP moly lube to the inside of nuts
4. Install studs or head then studs(your choice)
5. Install washers and lubed nuts
6. Torque nuts to specified torque

[moses]

^Thanks man.
