Crank Pulley Bolt Torque Recommendation
 

I'm going to be replacing the crank pulley with a 20% UDP this Thursday. Anyone know the proper torque amount for when I put the bolt back in?

Thanks.

I just googled this - I'm at work and very bored right now - and came up with this on my first try:

(for 2007 tC)

Engine Torque Specs Cylinder head Renew bolts – – –
Maximum bolt length 164.2 mm
Torque 29 ft. lbs.
Torque 58 ft. lbs.

Stage 2 2)18 ft. lbs. 3)90°
Oil pump to cylinder block 14 ft. lbs.
Oil pan bolts 7 ft. lbs.
Oil pan drain bolt 30 ft. lbs.
Drive plate 72 ft. lbs.
Torque converter 30 ft. lbs.
Flywheel 96 ft. lbs.
Clutch cover to flywheel 14 ft. lbs.
Crankshaft pulley/damper center bolt 133 ft. lbs.
Camshaft sprocket/gear 40 ft. lbs.
Camshaft carrier/cap –
Camshaft/valve cover 8 ft. lbs.
Intake manifold to cylinder head 22 ft. lbs.
Exhaust manifold to cylinder head 27 ft. lbs.
Spark plugs – – –
Crankshaft position sensor 7 ft. lbs.
Oxygen sensor (Lambda) 32 ft. lbs.
Knock sensor 15 ft. lbs.
Front hub 159 ft. lbs.
Rear hub 103 ft. lbs.
Steering track rod end 36 ft. lbs.
Brake caliper to carrier front 25 ft. lbs.
Brake caliper carrier to hub front 79 ft. lbs.
Brake caliper to carrier rear –
Brake caliper carrier to hub rear 34 ft. lbs.
ABS sensor front/rear 6 ft. lbs./–
Road wheels 76 ft. lbs.

ft. lbs.=foot pounds
ins. lbs.=inch pounds
°=angular torque
↓=proceed to next stage

So, if this source [http://www.club-tc.com/forums/engine...ications.html] is to be trusted, the answer to your question is: 133 ft.lbs.

Thanks, I honestly did not even think Google would come with a good result, but thats a pretty nice chart. I know some guys on here have done it, so Ill see if anyone confirms the 133.

Come to think of it, do various lightweight alloy pulleys - which must have different thermal expansion (and tensile) characteristics than OEM steel pulleys - require that differing amounts of torque be applied upon their installation?

I suppose the manufacturers would supply those numbers as necessary, though, wouldn't they?

Good question. I may need to email NST also.

Looks like a good source, thanks. Just gotta wait on Thursday now.
