Note Time-Saver: If you are on a PC, use the "Find Box" to search for a specific "Tractor Model" or whatever your looking for, on this page. Hold down the Ctrl key, tap the letter F, type or paste in a word, words or numbers in the pop-up box, then click in the box, next or an arrow.
What ever you typed into the box, if it exists in 'that sequence' on this page, it will be highlighted through-out this page. It saves you a lot of time scrolling down the page to find what your looking for. It's a great tool that can be used on any webpage.

LEGEND
* ZT tractors with RE engine prior to RE73108 and R tractors with EE engines prior to 413963 were equipped with a RE451 or RE451A cam intake tappet gap is 0.012 hot and the exhaust tappet gap is 0.014 hot.
Later production Z and R tractor engines were equipped 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 repair number) rocker arms. It is recommended that you remove the crankcase cover and check camshaft part numbers before adjusting the tappets clearances.
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 installed it should have RE108C or RE 5109 rocker arms.
** Plug electrode gap is 0.022-0.025 for gasoline, 0.025-0.027 for tractor 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't 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.
