Little Red 10-26-2012 12:13:09 216.105.223.2 Report to Moderator	My tractor cranks very slow 12v neg ground gas. the battery is almost new cables are all clean and tight timming is dead nuts on . if I shut the hyd bypass off on the pump off it does crank almost twice as fast but thats a pain to do every time, could my pump be building to much pressure ?? Thanks for any suggestions on this Doug R [Reply]   [No Email]

If de-stroking frt pump doubles cranking speed then there is an underlying hyd problem that I think a brand new starter won't correct. If the manual de-stroking screw is too inconvenient one could install a high $$$$ electric DS screw. [Reply]  [No Email]

Now let's back up step and find out for sure the problem. Did the slow cranking start with temp change or did it do this in warm weather? Destroking the pump is a bandaid option, not a fix for every slow cranking tractor. How old is the starter and have you had it checked recently? Old starters and poorly rebuilt ones are weak and don't have guts they should. If it's getting weak of course a destroker will help for a little while. You still will have a dieing starter. A small gas engine like that should crank fine on very cold days without a destroker if your starter, cable connections, cables, and starter solenoid are all in good shape. And yes when used in the correct situations a destroker is a great thing. One last thing, make sure the cables are actually good all the way thru. Old cables lose fibers and cannot carry current loads they used too. This post was edited by 4020_1966 at 21:44:48 10/26/12. [Reply]  [No Email]
