Goldnboy 1,035 #1 Posted September 2, 2019 I replaced the 8hp Engine and installed a 14Hp today all went well untill I engaged the PTO and it would not spin. So I loosened the mule drive and it would spin but the belt was floppy and it sounded odd. When I installed the drive pulley it was about a 1/4" away from the belt guard for clearance. Then I put the friction disc and pto bell. I did notice that the pto brake couldn't be installed. Can anyone point me to correct distance? Share this post Link to post Share on other sites
pfrederi 18,719 #2 Posted September 2, 2019 Tranny drive pulley should be about 1/8 - 3/16 out from the block 1 Share this post Link to post Share on other sites
Goldnboy 1,035 #3 Posted September 2, 2019 (edited) Here is a closeup picture. The above picture with pto brake is old engine before I removed. Edited September 2, 2019 by Goldnboy Share this post Link to post Share on other sites
pfrederi 18,719 #4 Posted September 3, 2019 Is teh crank shaft on the new 14 hp the correct length? Did it come from another WH??? Share this post Link to post Share on other sites
Goldnboy 1,035 #5 Posted September 3, 2019 Its a simplicity spec motor, changed to wheelhorse specs. Crank is 3 1/8" but 1" diameter, but I have the correct drive pulley. Share this post Link to post Share on other sites
Goldnboy 1,035 #6 Posted September 3, 2019 The old setup is shown below with a large gap between disc on the K181. Share this post Link to post Share on other sites
chip61 666 #7 Posted September 3, 2019 does the pto lever "snap" into place when you engage it?? None of my pto clutches have that much clearance when disengaged. I bought a C141 recently that the deck would stop turning as soon as I hit any grass. I tightened the adjustment and it works as it should. 1 Share this post Link to post Share on other sites
pfrederi 18,719 #8 Posted September 3, 2019 The 8 hp engine you had uses a different Engine bracket (blue arrow) for the PTO (104732) than the big block models (104729) That may be your problem. Share this post Link to post Share on other sites

I had already planned for the different Bracket size. Share this post Link to post Share on other sites
Goldnboy 1,035 #10 Posted September 3, 2019 The engine also run with the PTO before rebuilding. Share this post Link to post Share on other sites
Stepney 2,354 #11 Posted September 3, 2019 Think I saw this question up on the FB page. Your clutch gap looks way too wide. Sounds like your just too loose. Share this post Link to post Share on other sites
Goldnboy 1,035 #12 Posted September 7, 2019 (edited) The gap between the friction disc wasn't the problem, I moved the drive pulley in to 1/4" from the engine block. Put the belt on the Pto bell and noticed the belt was frayed along the ends, and after investigating more the belt slipped onto the bottom grove of the middle deck spindle. Well that was a good way to destroy the mule drive belt. So I installed my spare mule drive belt and double checked the mule pulleys and put it back together and mowed the yard.
