I'll be picking up the new valves, guides, springs, and gaskets over the weekend. When I start going back together with it, what is the proper head bolt torque and valve lash adjustment? Hercules GO130 gas. TIA!!
Here you go....
Clearance is 0.010 for intake and exhaust
Thanks Chris!! That's just what I needed!!
Is that hot or cold Chris?

That's a good question Blake. I always adjust valves in my wheel tractors cold, so I didn't even think to ask. Thanks for asking!!
A lot of engines give their clearances as hot. 0.010" just seems a little tight for an overhead valve engine when set cold as you will have lineal expansion of the pushrod. Maybe I am wrong and it is cold, but I just thought one should double check.
Hey Oliverchris--Is that valve lash hot or cold, and does the rear head bolt (drilled) get torqued to 140 also. I have snapped a drilled one on one of my Oliver wheel tractors once. It wasn't too big a deal as it was a bolt and a long nail fit down in it tight and turned the broken threads out. This one being a stud wouldn't be so simple if it breaks!
0.012 cold — 0.010 hot after final cylinder head bolt torque to 140ft.lbs (that is after engine is brought up to operating temperature, remove rocker assembly again, re-torque, then back to operating temp., then re-check/set valve gap). That drilled stud is same torque according to shop manual.
Some of Chris' posts are coming up blank to me. Anyone else having that problem? The text is actually there, but not showing up. When I reply with quote it comes up. Below is his post:

Trying again:
0.012 cold — 0.010 hot after final cylinder head bolt torque to 140ft.lbs (that is after engine is brought up to operating temperature, remove rocker assembly again, re-torque, then back to operating temp., then re-check/set valve gap). That drilled stud is same torque according to shop manual.

Blank. I can tell it's there, but not showing.
Yes. This post shows up ok. Your previous one still does not.

How weird. I just logged out and in again - any better? Time to clean up the old hard drive, and see what's cookin', I guess
That's weird, they all show up for me, or am I just special?
All his posts are showing up, down here in Virginia. Good info to have too!
I switched browsers. Reply #8 and #10 still show up as blank.
I have no idea. Never had this happen with anyone else's posts.
My computer and Blake's computer are having one of those relationship 'things' :D
I'm getting everything just fine---and thanks Chris for the clarification!!
