Mudrig150 336 #1 Posted June 12, 2019 So we were at an auction yesterday, and after losing 3 different things we wanted I thought we weren't coming home with anything. Then my brother decides to just buy me a walk behind with a briggs 8 hp, and a 414-8! It only sometimes turns over and the choke cable is stuck. It doesn't start either. Brother is taking the motor for his JD, and after I do that and pay him 50$ it's mine. 7 Share this post Link to post Share on other sites
Achto 29,433 #2 Posted June 12, 2019 Nice tractor!! Too bad you don't have a 14hp Kohler to trade him for the complete tractor. You can put a different engine in this tractor but you will need to make sure that the engine you choose has a thrust bearing on the crank if you want to run the stock PTO clutch or you will need to switch to an electric PTO clutch. 2 Share this post Link to post Share on other sites
Mudrig150 336 #3 Posted June 12, 2019 (edited) Thrust bearing on the crank? I didn't know they had thrust bearings. Well he just wants the magnum 14 for uniqueness and the low power that the coil uses. I might add a twin cylinder or put my 14 horse in.

Achto 29,433 #4 Posted June 12, 2019 (edited) 6 hours ago, Mudrig150 said: Thrust bearing on the crank? I didn't know they had thrust bearings. Wheel Horse spec'd the engines out to have a trust bearing on the PTO side when used with the friction type PTO clutch. When you engage the PTO it puts inward pressure on the crank thus a thrust bearing is required to keep from damaging the crank. If you put an engine in without a thrust bearing on the PTO side then you will have to switch to an electric PTO clutch if you wish to use the PTO. Other wise you will take out the crank on the engine. Edited June 13, 2019 by Achto Share this post Link to post Share on other sites
pfrederi 18,719 #5 Posted June 14, 2019 Magnum singles all had ball bearings on the crank so they could handle end loading. Magnum Twins did not have ball bearings and most Spec#s did NOT come with a trust bearing. A very few variations have a thrust beairng (WH used them). You have to look up the specific spec number to see if it has a thrust bearing. Share this post Link to post Share on other sites
Mudrig150 336 #6 Posted July 7, 2019 So we haven'd done much on the 414-8. We did modify the mounting plate to get rid of the busted magnum starter. Now we can fit a K series starter on and not have to deal with the crap that mounts those stupid starters on. Just need to mount the starter that my brother broke and I fixed. 30 seconds on the motor and he had already ruined the brush and brush cap on the dang thing!!!

Mudrig150 336 #7 Posted August 11, 2019 So we tried to start the 414-8, but it didn't go so well. The starter locked up and something is wrong with the carb. The gravity fed tank works a lot better then the busted fuel pump which won't even pump out drops of fuel. Guess I'll have to pull the diptsick again to retrieve the busted starter.
