Valve Job on a WD45?

You guys all go take a pill or somethin!!!

I'm Sorry. I didn't resist the earge to enter the slide away from the question as I should have.

Okay, Pank-  time to learn to read, then think, without opening mouth- you've already got two feet in it already:

"if you can't get the valve to move by pressing with the heel of your hand, you've got plenty of seat force."

How does this test condemn a spring?  DUH-- it doesn't... but it DOES prove that the spring is stout enough to not need a lick of attention.

You're right on about the grinding process, Dick-  I've got a slick little valve grinder and several different  guide-mandrel type motorized grinding tools  here- one of 'em is somewhat of a rarity- it's a Brown & Sharpe from the early '50's, and it does a really nice job, but I've only needed it twice... once many years ago for a Hercules JXLD (331ci  flathead six) in a generator that I rescued, and most recently in a Fairbanks-Morse 118ci oilfield single.  The former had been sitting with that port full of rain, and the valve yanked the seat out when I rolled it over, and the latter had it's exhaust valve stem incredibly-well adhered to the guide... I had to torch the (sodium filled) valve out, in order to drive the guide and stem duo out, and push in a new guide. In the process, I spalled a little spot in the guide, but rather than yank out an otherwise perfectly good piece, I just ground it a smidgen, lapped it in, and put it back together.  I've never found need to employ the grinder on any Allis heads, nor have I ever found a head that needed a $300 bill to get a cylinder head solidly back in the land of the living.  Reiterating his original explanation... he was bushhogging, and it got fussy... went to pull a plug, and the plug broke off.  If he was bushhogging, I'm thinkin' it wasn't in too bad'a shape to begin with.

Now, Pankey's original allegation was that valve damage should be expected on the basis that the Allis engine was somehow intolerant of fuels without lead.  I called him on this lie, and he should've been bright enough to not go there in the first place.  He's got a little inferiority complex going on.  Perhaps someday he'll learn that lying to newbies is the number-one way to dash friendships old-and-new, but based on how he's treated people elsewhere, I really don't think that's going to happen.

Just thought I would try to relieve the tension among our orange friends!! Ryan

if i lied or mislead with picture as much as some get question from others about there pictures of clutches etc. it would appear my parts would be still in classifieds and not sold but my have sold and yours even with me saying its cheap  enough are stll in the classifieds . i never offered 200 to seei. it was a bet that it wouldnt flow those numbersyou advetized and you declined. I have cranks cylinders heads etc. in several  eastern united states.

somebody post his picture so when someone sees something to question besides me he can say oh it was just laying there or was used to line something else up .notice he also said he was going to send it to machine shop to be bored . he has pictures and leads one to think he does his machine work. line boring or honing isnt any trouble at all.  i like to se a wormy fellow like yourself do what you imply. probably be another lie you tell

I'm now a wormey fella. I've had polmolive hands, been a 40 yr old machinest, been a 20 yr old kid, even been told I was to broke to have a couple hundred bucks to fix my tractor.   All made up by the same idiot in a desperate attempt for attention makes up whatever he can.

Update:  The machine shop cleaned and tested the head, and the valves are in great shape (which is amazing considering that it hasn't been overhauled to my knowledge in the past 30-40 years).  The broken spark plug and two manifold bolts were drilled out, and the total bill is $80.  Not bad for piece of mind, but that was one expensive and time consuming broken spark plug.

If i remember correctly its 90 lbs on the 1/2 inch and 55 on the smaller bolts . without the manual in front of me . start with the center bolts and work your way to the ends

This is what my manual states.

The specs I got were from the wd-45 manual I have.

My original Torque values (90 lbs and 25 lbs) were taken from this manual.

The one I have is the I&T shop manual for B, Rc, Wd45 Diesel, C, Wc, Ca, Wd, Wf, G Wd45 models.

Dave,
Funny you mentioned that explanation about lapping in the valves, and in about 2 hours have the head ready to go. That's exactly what I did to my WC's cylinder head this past summer. I re-installed the cylinder head, stuck the Mag in and set the Mag timing, but never got to fire the engine because we sold the house, and it continued to rain, and had to move everything. I just fired the WC's engine tonight since I assembled the top half last summer, and it fired right up and ran pretty smoothly even in the cold weather. I didn't run it to long because there wasn't much coolant in the system yet, but for a "quicky" lap job and a freshing up, it worked out quite nicely. No smoke either. Now my B was another story. I had to install new seats, valves, n' guides. That cylinder head was hurtin'.....  LOL!
