F-head valve adjustment

How difficult is it to do a valve adjustment on an F head? Any special tools required. Any tips? I have my universal service manual which I will refer too. But it doesn't really describe much about the process.

 

I couldn't find the procedure in the manual either. #1 cylinder to tdc compression stroke, set #1 cylinder. turn engine 180 degrees, set #2 cylinder. turn 180, set #3. turn 180, set #4. Haven't done the exhaust since the manifold was back on but the intakes are easy, just a half inch wrench and a screwdriver.

 

Exhaust are very easy with the fender off, remove side cover from engine. You need two 1/2" thin wrenches one slightly bent to make it easier to handle both. Set to .014". One wrench loosens the lock nut while the other holds the tappet adjuster still while you tighten the lock nut.

found this on the "G"

Do you mean Cylinder #1 , #2,#3,#4 in that order? Or cylinder #1, turn 180 degrees, then Cylinder #3, turn 180 degrees, Cylinder #4, turn 180 degrees, and finally Cylinder #2??:?

I started with Cylinder#1 exhaust valve with the timing marks lined up and with the distributor pointing to cylinder #1 spark plug wire. I think that should be #1 on compression stroke. Turned 180 and did Cylinder #2, turned 180 and Then #3, went to check distributor position and it was pointing to #4 cylinder. So it must be done in firing order?:?

 

hope I am not confused here but I thought that the valve lash was supposed to be .018 for intake and .016 for exhaust, Is the .014 a misprint?

 

(double post, sorry)

 

I read (Jeep Owners Bible) that the older, non rotator cap style were set to .012", and the rotator cap type, (the kind most everyone probably has) are set to .016". As far as the procedure, I went through this a few weeks ago....Try this thread, its how I got through mine.

Go with your manual, I'll try to find the service bulletin for the .014

 

I'm with Brian_P, 0.018 and 0.016, maybe both at 0.017 if desired.
No special tools. No removing fender. No big deal ... plan for some time though.
As Dummy said in an older thread, adjust when cam heel is centered at pushrod or tappet.
Anxious to see a bullitin that states a different lash.

 

I found the Service bulletin for the Lhead on the G503 forum, it specifies the 014. So if you r just a tad tight on the .016 I'd go with it.

 

Interesting. I see the .014 is for the L-Head, I wonder if it applies to both L & F-Heads on the bullitin or just the L-Head. Just thinking out loud here but I wonder if the larger intake valves and slightly improved breathing of the F-Head made it run a little hotter and hence the .016 on the exhaust if the bullitin does not specify both engines.

I understand lots of changes have been made over time during production. .014 may well be plenty, Its just a number I am not used to looking at ..........theres allways something new to learn
