Timing Chain Cover ~ Bolt Torque

[Infidel Edition]

Am I reading this right...
60 foot pounds on those 10mm bolts?
Seems like alot.

So I prepped and finger tight mounted the cover, put on the harmonic balancer... went to torque the cover bolts...
To discover there's 2 I can't access with the balancer installed.
Tightened the others down to hold it in place, removed the balancer, tightened those 2.
Then saw the torque spec and left them at 30#
Put the balancer back on so I could return the tool.

All the bolts are at 30 ft/lbs
Guess I'll have to tighten them another 30 lbs tomorrow when I go back.

No, that would snap them or strip them. You sure it isn't 60 inch pounds?

[Infidel Edition]

I left the reference book in the storage unit.

Wouldn't 60 in/lbs be like 5 ft/lbs?
That sounds too light.

I would have guessed more like 12-15 ft/lbs.
I've never actually torqued the cover before. Always just done it be feel....

Just a suggestion. Better check it again

[Infidel Edition]

Not only double check...
But will probably replace them as they're torqued to 30 ft/lbs
~ which would be 6X recommended.
and those bolts are the 1's I pulled off the donor block.
Couple bucks for new bolts = piece of mind

According to that page and a few others I found, it says 5ft lbs, and 60in lbs for the torque value of that cover.. I would say if you can get new bolts, might as well... only be a few bucks... and like you said will provide peace of mind anyways...

This from a 2000 manual, 4.0L engine .... inlbs seems more appropriate:

I like that it separates in/Lbs on that chart...
The jeep engine rebuild book I'm following (stroker build) doesn't do a good job of keeping the 2 separate...

I replaced all but 2 of the bolts (didn't want to pull the balancer off to get to those)
And torqued correctly.
* Replaced because I WAY over torqued them by my error...
