Tri Z cylinder head torque settings

[Jason T]

I'm just putting a new piston in my 1986 Tri-z, can anyone tell me the torque settings for the head bolts and cylinder to crankcase bolts? Also should these be done up in any specific sequence?

Thanks

I do ALL my head nut's to 22pnd's and the cylinder nut's I tighten as hard as I can with a open end wrench..never had one blow out

head nuts do in a alternating pattern
the cylinder nuts snug tight then go in a alt pattern

Thanks for the quick reply;)
Sorry to sound stupid, but what are PND's?

pnd's is short for pounds.
Torque wrenches and torque specifications are usually rated
in ft/lb (meaning foot/pounds) or Nm (meaning Newton meters)

My Z manual lists head nuts at 18 ft/lb and
cylinder nuts at 25 ft/lb

(Listen to Raff, he knows heaps)

Lubricate the threads, cross tighten. Make sure the threads are good (no burs) Better if youre not experienced to buy at least a cheap torque wrench. I hand tighten them too, but have been doing it for years and check it against a torque wrench occasionally.

Thanks for all the replies:)
I was expecting a figure with either ft/lb or Nm at the end, so pnd's threw me a bit lol
Don't worry, we have a torque wrench, I won't be guessing it;)

just a heads up, when i did mine it started leaking antifreeze form the head after first ride. Just had to retourque the head and then it was fine. Good luck man

after you first start it let it run for 10min and then let completly cool down.. then retourque..to check your FOOT POUNDS..:lol:

PND's, ft/lb's or Nm's it doesn't matter now because its in a whole piece!! lol
