Massey 65-news help ID engine.

[Mean Jean]

Replacing the valve cover gasket on a Massey 65 and need to confirm the proper valve cover gasket. I see this tractor came with 2 different Diesel engines:

Perkins 4A-203.
It's a 203.5 cubic inch L head engine.
Or
Perkins A4.192
It's a 192 cubic inch engine.

Serial number of tractor is 681068.
Stamper number of motor is RMO 18826-1.

Valve cover has 3 nuts to hold the cover down instead of the usual 6-10 which are along the perimeter. Not sure why I can't post a picture..,

Also

Should I adjust the valve clearance while I'm in there?

Thanks all

i would adjust the valves while cover is off .
call a massey and give them your numbers and tell what you need they should be able to look it up for you
