SOURCE: 93 artic cat jag head torque pattern and specs

the best place to find it is the service manual. if not avail. i usually 1, tighten it to ~10-20Nm in a 'outwards spiral' fashion, ie start tightening from centre bolts outwards. 2, spiral tighten by 1/4 turn, 3, another 1/4 turn, and 4, final 1/4 turn.

SOURCE: generator cover bolt pattern specs?

You can do the job yourself with no problem. No specific pattern for the side cover. BUT, get all the screws started then just bring them all slightly snug. Now tighten one screw and then go kitty corner and tighten another now drop down and pick a screw mid way between the first two screws and tighten it. Now do the kitty corner thing again and so on. As you know, the idea is to tighten the screws evenly around the entire cover.

As to torque, a 6mm screw gets 7 foot pounds or 85 inch pounds.
Realistically, no one ever bothers with torque on small screws. You will want to spend $15 to $20 and get yourself an impact driver to tighten or loosen screws. The tool is about 6" long and 2" in diameter and has a 3/8" drive on one end. Your socket set will fit it as well as screw driver bits. Just engage the bit into the head of the screw and strike the end of the impact driver with a hammer while twisting the tool to tighten the screw. This is the most valuable tool in my shop and I use one (Blue Point brand) that I got 40 years ago. They last well and can be used on any screw, bolt or nut that needs a little persuasion.

Please rate this solution as a "FixYa" if I have helped. Thanks!

Head bolt torque yield


90% of head bolts are stretched when installed. If you have the torque settings, you can confirm this by checking the specs. If it says example, 90lbs feet, plus a quarter turn, this confirms they are gonna stretch once torqued.
In any case, yes, change those head bolts at all costs. DO NOT RE-USE THEM. Make sure to torque and in the order as well. do not use a random pattern when torqueing.

Gererac 5500 XL with an EHF00945 11 HP engine What is the torque for the 4 head bolts?


Hi and welcome to FixYa, I am Kelly
I have tried going to the owner's manual and the parts listings

Owner's
http://www.managemylife.com/mmh/lis_pdf/OWNM/L0208260.pdf

Part's listings
http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Generator-Parts/Model-580327160/0247/0702250/P0208117/00007?blt=06&prst=&shdMod=

I even know the cylinder head has 4 bolts and the head part number is 21714
Yet nothing I have looked at tells me the actual engine number. With and actual engine Model Number I can answer your question without guessing which engine you have.

This appears to be a GN320 engine.
If that is the case... the torque is 44 Ft Lbs

CHECKING/ADJUSTING VALVE TO

ROCKER ARM CLEARANCE

Every 50 hours of operation, remove the rocker cover and

check the valve to rocker arm clearance.

When adjusting the clearance, the engine should be at room

temperature, and the piston should be at Top Dead Center

(TDC) of its compression stroke (both valves are closed). The
correct clearance is 0.05-0.1mm (0.002-0.004 in.).

Jam nuts 65-85 inch lbs
