I had a page viewer last spring say he thought this would be usefull information for this sight. Sorry it's taken me so long to get it together and up here.  This information all came from a collection of I&T Shop Service manuals. Please check it over if you see any mistake or question anything please let me know you can e-mail me at mmpulling@yahoo.com or leave a message on the Discussion Board. As far as I know it is all correct.

* ZT tractors with RE engine prior to RE73108 and R tractors with EE engines prior to 413963 were equiped with a RE451 or RE451A cam intake tappet gap is 0.012hot and the exhaust tappet gap is 0.014hot. Later production Z and R tractor engines were equiped with RE451B cams intake tappet gap is 0.008 hot exhaust gap is 0.010.  NOTE: some early tractors with RE 451 and RE451A cams had the new RE451B cam installed later along with RE 108C  (RE5109 repaire number) rocker arms.  It is recommended that you remove the crankcase cover and check camshaft part numbers before adjusting the tappets clearnces.  If you don't want to remove the side pan I'd suggest looking at the part number on the rocker arms.  If the new cam shaft has been instaled it should have RE108C or RE 5109 rocker arms.

** Plug electrode gap is 0.022-0.025 for gasoline,  0.025-0.027 for tracor fuel, 0.020-0.022 for LP engines in 335 and 445 for Jet Star and 4 Star LP engines 0.014-0.016

*** I don' have information on this but I recommend 0.022 same as M670 and 5 star.

****Massey-Ferguson 95 after SN 17300000

??? I'm not sure there were any of these tractors that came out of the factory on gasoline.
