valve lash Adjusting

Ok I managed to get the engine all assembled and installed today and am setting valve lash but the book does not really tell you much other than the setting of .010 for each valve. what cylinders do you lash when the front cylinder is on TDC ? then you must roll it 180 degrees and then do the other two ?
 
I start with #1 cyl on tdc compression stroke, adjust both valves, then put #2 cyl on tdc, and right on down the line. There are charts that show how many you can adjust at a time with a certain cyl at tdc, it may take a little longer my way, and you gotta turn the engine more, but thats the way I've always done it.
 
I adjusted them with the motor running. Just slide in your feeler gage and adjust. It can be a little tricky but it works with good results.
 
ok, when 1 cyl. is on tdc of the compression stroke you adjust both of #1 cyl's valves.
then roll it 180 degree's tells me its a four cyl.for example the firing order is 1342. you adjust the valves in the firing order sequence.
1 3
4 2 the running mate of #1 is #4 so you watch #4 cyl's valves to get them on the rock. meaning one valve is closing and the other one is opening. cause if you rock the crank the valves do the same. after you adjust #1 cyl. you rotate crank and watch #2 cyl. to get it on the rock and adjust #3 cyl. after that one is adjusted you crank it over till #1 is on the rock then adjust #4 cyl. then crank it till #3 is on the rock and adjust #2 cyl. and your done.
you must follow the firing order when adjusting valves. 1342 is an example for ihc, but not sure what allis has.
this procedure was taught to me in mech. school 35 yrs. ago and is very easy to follow. when i adjust valves i dont even have to remove the spark plugs cause i know when #1 cyl. is on compression just by watching the running mates valves. then just follow the firing order.
 
With number one TDC on compression stroke you can do both on number one, number two exhaust and number three intake. With number four TDC on compression stroke do the remaining four.
 
Brew I should add what I replied is the way My shop manual describes for the D series non diesel tractors. That is the way I do my WD. If I am not mistaken it would work on all Allis foucylinder gas models.

The way I get it in my head is set number one cylinder. from front to rear do two, skip one do one, skip one do one, leave two.

Then set number four and work the same way from front to rear.

Hope this helps.
 
Well I managed to get the valves adjusted using rustred's method. Thank you to all who replied !!! All of the help that is given on this site is awesome.
 
the easiest way to adjust valve lash is to have the valve on the heel of the cam is to adjust one at a time . adjust number one int.valve just as the no.1 exh.valve starts down and the exhaust valve as the number one int. valve just starts to move toward closing after being all the way open . then repeat this on the next number of cylinders.
