How can you look at a camshaft and tell whether or not it needs to be re-ground.

Clooney, Up here at John Deere where I work we have specifications for the lobe hight, and valve lift on new tractors. I dont know how available these specs are for two cylinder tractors. I presume one way is to mike out the lobes on a new cam and compare the values to yours. I did this on my 46-A. I just decided to get a new cam for it instead of having it reground. Hope this helps with your question. If you have a particular tractor in mind...I may be able to get you these specifacations, let me know.

Thanks,

Dave Thuesen

AWB, well you can't always tell by looking. The best way is to run a profile on it against it's lift, duration & opening/closing specs, [if you can find them].
~You can look for certain items that will point to a cam problem though...
~Look for flat spots, pitting, flat or different shaped lobe tops, short lift on one or more valves, cup shaped wear on the lifters or severe angel wear on the followers.
~One of the hardest things to spot & one thing really effects cam performance is slight wear on the take up ramp that takes the lash out of the lifter before the actual lift starts. ~A good rule to live by is assume a cam is worn unless you degree it out against the specs to prove it good.....
