Need Torque

[Nate C]

Anyone know torque specs on the following:

 

Timing chain cover

Oil Pan

valve cover 

 

Got some fel-pro gaskets and hope to get these installed this weekend. I think the Valve cover is 55 inch pounds,...

 

Also replacing the harmonic balancer and chain cover, I'll get the puller tool for the balancer. Anything special I need to 

know or look out for on this job? I'm not going to mess up the timing am I?

From the 1991 FSM:

 

Timing cover: 62 in-lbs.

Oil pan: 7 ft-lbs for small bolts and 11 ft-lbs for large bolts

Valve cover: 55 in-lbs.

 

As long as you don't rotate the engine without the timing chain installed the timing will not change.

 

I would strongly recommend getting a harmonic balancer installation tool to install the new HB (or a longer 1/2-20 bolt). Don't use the crank bolt to pull it on or you run the risk of wiping the threads from the crankshaft snout, crank bolt or both. Otherwise it's a simple R&R job. Torque spec is 80 ft-lbs for the crank bolt.

 

Are you also replacing the timing chain? If not it might be a good "while you're in there" thing.

 

:thumbsup:

 

This reminds me... I really need an inch pound torque wrench.

Awesome! thanks, dropped a new/rebuilt motor in it 5 years ago so the timing chain is good to go. Should have replaced the chain cover and that doughnut gasket back then. I think that's where my problem is. I'll head to Auto Zone in the morning to grab that tool, Ha yeah I just picked up an inch pound wrench for this job, should come in handy.

Count the number of turns it takes to tighten the bolt until the head twists off. Tighten the rest of the bolts one half turn less.  :fs1:

*** I'm in the middle of it right now,.... do you know the torque for the water pump and other pullies? Picked up some new may as swap those out while I'm in there. ***

Water pump: 13 ft-lbs. No specs given for the pulley. (I take this to mean "tighten to make-sure-this-doesn't-fall-off ft-lbs")

Clutch fan nuts: 18 ft-lbs. Also no specs given for the pulley.

Power steering bolts: Front bolts: 30 ft-lbs. Rear bolts: 20 ft-lbs. No spec given for the top pivot bolt (just make sure it's snug). My FSM incorrectly refers to the same figure twice, so these may be backwards.

 

Is this what you needed? If not I'll comb through the FSM some more. Would be nice if it just had a list of torque specs but it unfortunately does not. Also, when you put the timing cover back together remember to put the "oil slinger" (the cup-shaped thing behind the timing cover) back on the crankshaft with the "cup" facing out.
