grinchsr 647 #1 Posted February 19, 2023 I have a KT17 in the original 417A but the motor has a bad stator and the governor over revs even when set correctly which leads me to my question. What do I need to swap a Magnum motor into it? I have a complete harness already for the Magnum but I heard that I have to change the engine pulley? Can I run with an 8 speed pulley which the M14 has on it? I am guessing the ground speed will slow down. Share this post Link to post Share on other sites
Bill D 2,246 #2 Posted February 19, 2023 Change the pulley to a hydro pulley. The clutch hoop is also different from the KT 17 vs the M14. The charging stator connection is the same on both engines. Add a 5 pin relay in place of the coil on the KT 17 and use it to kill the M14. The KT 17 has a powered ignition, the M14 does not. I'm not sure about the wiring for the oil pressure light, but I'm sure someone else here can help with that. Hope that helps. Bill 1 Share this post Link to post Share on other sites
grinchsr 647 #3 Posted February 19, 2023 It does help thanks Bill. Is the hydro pulley bigger or smaller than the 8 speed? Share this post Link to post Share on other sites

Without the larger pulley transmission cooling is not as effective, ground speed will be slower and I believe transmission damage can occur. Hydros are designed to run at a constant and relatively high speed. 1 1 Share this post Link to post Share on other sites

BESTDOGEVER 218 #8 Posted February 23, 2023 Also not swapping the pulley changes the belt size and is more trouble than you need Share this post Link to post Share on other sites
grinchsr 647 #9 Posted February 23, 2023 Your right. I forgot about that Share this post Link to post Share on other sites
Sparky-(Admin) 23,145 #10 Posted February 24, 2023 I think the 8 speed pulley is a 4” and the hydro pulley is a 5”. Best bet would be to contact Lincoln at AZ Tractors in our vendors section and see if he has one. 1 Share this post Link to post Share on other sites
midpack 1,009 #11 Posted February 24, 2023 I left the hydro pulley on an 8 speed once, boy did that tractor move! 😂 1 Share this post Link to post Share on other sites

Bill D 2,246 #13 Posted February 24, 2023 (edited) Can you get the pulley off the KT17 easily? Edited February 24, 2023 by Bill D Share this post Link to post Share on other sites
grinchsr 647 #14 Posted February 24, 2023 Hi Bill. I have not tried yet but that brings up another question. Is the crank diameter the same for a KT17 and a M14? Share this post Link to post Share on other sites
