Fastener Torque Values [Merged 3-9] value tightness torques specs specifications

[GreddySpyder]

I changed my leaky oil pan gasket not long ago and it is still leaking. I used red rtv as the gasket and ran a nice continuous bead around the whole pan making a circle around each bolt hole. I think the two mistakes I made were not waiting for the RTV to dry before putting the pan back on, and I think I tightened the bolts too much ( I ended up breaking one of them).
I'm gonna buy a torque wrench and make sure they are right this time... how much torque do the pan bolts require? How long should I let the RTV dry this time before putting the pan back on?

hey i have a 7 bolt motor and im looking at the haynes manual and it says

main cap bolts for 2.0l turbo step 1.... 18 ft lbs no biggie deal. Step 2 90-degrees further.... just spin the bolt a extra 90 degress right?......

now step 2 rod cap nuts (stock pistons and rods just redoign the bearings on a old motor)

step 1.... 174 INCH-lbs ... wtf inch pounds my torque wrench and my mechanics torque wrenchs are all FT-lbs.... how much is 174 inch pounds in ft-lbs? also then says to turn 90 degress further... again turn it 90 degress past the 174 inch point? wtf how so confusing on hondas its like 18 ft-lbs and then 36 ft-lbs just straight out please help .'


also isnt 18 ft-lbs + the 90 degrees to low? i fiqured it would be in the 40s for torqueing down the main cap bolts
and only 174 / 12 = foot pounds ie.... 14.5 (why so low). and then again another 90 degress? CONFUSING YES....

 

[slowAWDTSi]

Yes the inch pounds are directly converted by dividing by 12. And from what you are saying , they are torque to yield bolts. But I was unaware that the rod nuts were. And did you check your Main bolts for stretching? They should be replaced if they have any signs of irregularity. Same with rod nuts and bolts, but they usually are fine. And yes on the 90 degrees (1/4 turn) and remember this is not a honda I dont have the DSM manual in front of me at the moment but Id double check those torque specs.

 

[hellraz0r1337]

i took the specs right out of the book


i guess ill just go by the 14.5 for the rod nuts and then a quarter turn...

seems kinda low but wtf the manual says so

 

[JWoodley]

Go with what it says. You don't want to strip out any threads on delicate parts.

Hello Dsmer's I was wondering by any chance can someone tell me what the stock flywheel bolt torque specifications are for the 2G 4G63?

 

[hellraz0r1337]

hey i also want to know hat ## guys are torqueing ## arp studs down to on the head in the manual again the numbers are a little low and also these are upgraded studs and a cometic head gasket im guessing a lil more torque is in the mix... help me out thanks

 

[luv2rallye]

98 ft-lbs

i have seen some guys torque their arp head bolts to 120-130 ft/lbs and have seen no side effects. But these were on track only cars that dont see much road time at all. ARP i think says torque to about 85 ft/lbs if i remember right.

 

[hellraz0r1337]

thank you

 

[C_Keagy]

i torque mine to 100 ft lbs. ive done this on all of my motors with no problems

 

[fourreGsixty3]

For ARPs... if you use ARPs molylube then do a 3 step TQing process( put them in hand tight, then TQ them to 25ft lbs, then loosen, then 50-55ft lbs, then loosen again, then tighten down to 85 ft lbs...this is using molylube for an example), then go drive the car, and heat cycle the motor, then pop the VC back off, then what I did was cracked them loose, then TQed them back to 85 ft lbs.

ARP TQing specs:
With molylube:85 FT LBS
With motor oil as lubricant:90-100 FT LBS
Dry: 115FT LBS (approx. 105, or 110 should be fine)

 

[LogikEvoIII]

thanks man, appreciate it.

Keep in mind, everyone here is giving torque specs for 6 bolt arp studs. The 7 bolt studs have a lower torque spec. Follow the instuctions on the paperwork that came with the studs. The torque specs will be there. Even a quick search on here could find all the specs you need. Im not going to spoon feed you so I suggest you learn how to use the search feature that is provided for you.

 

[long84les]

does anyone know how much torque to use when installing a clutch?

 

[snowborder714]

The pressure plate bolts should be torqued to 14-16 ft./lbs.

 

[long84les]

is that for the 4g63 or the 420a? what about bolting the trans back on?

 

[snowborder714]

It should be for either 420A or 4G63. I found the info from here - http://www.dsmtuners.com/forums/showthread.php?t=92351&highlight=pressure+plate

The bolts holding the transmission on are 35 ft./lbs.

Our pressure plate is riveted to the flywheel fyi.

 

[ShadeTreeDSM]

i did clutch and flywheel yesterday in my car. ACT streetlite flywheel & SBR4000 clutch. I got to the point where i didnt know the torque specs for the flywheel so i called SLOW BOY RACING and one of the guys there told me 35 ft lbs which seemed kind of on the lite side. : ( so i torqued it to about 40-42ft lbs with red locktite, is that still to light or should i take the tranny back out and retorque them ?

 

[eclipse94turbo]

ill tell you this my alumium flywheel is at 100 ft pounds with lock tight is thats what it said to do on here just search youll find the answers you need

 

[ShadeTreeDSM]

i did, i found nothing, i was asking if 40ft lbs would be enough or do i need to take my trans back out and redo this.

 

[TSITuner4Lyfe69]

those are the torque specs i got for my flywheel and its been like this for 2 years and no problems so i say your a-ok and i diddnt even use lock tite

Fly Wheel: 94-101 ft. lbs. or 140 NM of TQ (use hi-temp loctite (red tube)) Tighten down in star pattern.

Pressure plate to fly: 14-16 ft. lbs.

Main's: 18 ft. lbs. + 90* (1/4 turn)

Head stud's:
Apply hi-temp thread sealer to thread's, then hand tighten into block, then back them off (1) full turn. Put the head on one with washers, and nut's. Use the ARP Moly Lube and tighten in a 3 step process: Do them all at 25 ft. lbs., then 50 ft. lbs., then 80 ft. lbs (in order, and using moly lube), if using 10wt. motor oil finish tightening them down to 120 ft. lbs. After first heat cycle re-TQ them.

Valve cover: 2.3-2.5 ft. lbs.

Camshaft Bearing: 14 ft.lbs.

Oil pan: 5 ft. lbs.

Connecting rod:
18 ft/lbs + 90* (1/4 turn)

Exhaust manifold to head:
1G: 20 ft. lbs.
2G: 20 ft. lbs. on the small stud's, and 21 ft. lbs. on the 2 larger outer stud's

Cam Caps: 14-15 ft. lbs.

Oil pump housing: 11-13 ft. lbs. (apply a dab of loctite to the bolt's before instalation)

Front case: 11-16 ft. lbs. Except the 10mm bolt which must be tightened to 20-25 ft. lbs.


Well I figured I'd contribute these, and perhap's they will help. These were pulled from my factory manual/CD-ROM manual.

PS: If anyone else has any spec's to add, or torquing pattern pic's please do so. It would be nice if we could get it stickied so it's a one stop thread for those without manual's.

6 Bolt mains: 47 - 51 ft lbs.

6 Bolt Connecting Rod: 36 ft lbs.

There's nothing really exotic about torquing fasteners, although some exotic metals allow you to apply more than routine torque, and some softer metals that you're threading into will allow less than normal:
