[AT] John Deere Head Lead Washers

[charlie hill]

Ray,  you say you don't know if your Allis is a D-10 or D-12?
Is the serial number readable?  It is on the downward sloping edge of
the torque tube flange just under the gas tank sediment bowl.
It should say D10-xxxxx or D12-xxxxx.  There are some other clues but
right now I'd have to think about it a bit.  If you can find the serial 
number
we won't need them.  Sometimes the number is hard to read because it
is simply punched into the metal with a set of punches and not always too
carefully.

The lead washers you talked about-are they on the valve cover bolts or 
somewhere else?
if they went on top of the valve cover under the nuts they are simply to 
seal those holes and
I believe were used in the days before modern rubber and steel washers.   If 
they went somewhere
else I'll have to do some reading.

Charlie

    I Just completed installing the cyl head on my 1940 B using the lead 
washers. I am no mechanic but I rememberJR Hobbs being adamant that they 
must be used. What is the purpose of these washers? I noticed as I came to 
the required torque they started to crush and surround the nut.
    This tractor was stuck, I got it freed by attaching a come-a-long to the 
front of the frame and the flywheel and a lot of penetrating oil reversing 
the pressure on the flywheel. There was a discussion on the list here on how 
to get a engine unstuck. What I saw after I got the head off I would never 
run a engine after it was stuck without cleaning the cylinders. I pulled 
handfuls of crap out of them, and this tractor had not been stuck all that 
long.
    What I thought was interesting was the low compression enging. All 
engines I have seen the piston comes at lest even with the deck, this engine 
they came about a inch below the deck.
    On EBAY I ordered all three gauges for 24.00. They are new and new 
(white face) from India shipment takes about a monththe last I checked the 
tracking they are in Dallas. We'll see when they get here if they are worth 
the money.
    One thing I can laugh at now. When I installed one of the pistons in I 
puched it too far and the oil ring came out of the cylinder. I am lucky that 
I have small hands and could get a ring compressor on it and push it 
forward. Very small space and and awkward angle.
    Also I have never before set the clearance of the rod bearings using 
shims.
Looking fowards to get it running.

PS: there was a discussion about a JD 430 V, I had one and sold it about 12 
years ago, put  ad in Green Mag. I had People fighting over it to buy it.Did 
not make friends with the people who didn't get it.
