pfrederi 17,147 #2 Posted April 19, 2015 First look at coupling between motor and pump. The splines may have stripped, motor turning but not the pump. Second open the tow valve and push the tractor any weird noises from the rear end ? Broken differential bolts etc.... Share this post Link to post Share on other sites

alswagg 128 #4 Posted April 20, 2015 I bet the coupler splines spun. That makes a terrible sound. I repaired mine with drilling and tapping for a set screw on the load side of the coupler. Fairly easy fix. If the lift hydraulics don't work check the coupler I bet the coupler splines spun. That makes a terrible sound.

Niagara D 11 #5 Posted April 20, 2015 I also had the same problem just today. I picked up a new to me '73 d180 yesterday and after just a half hour playing in the yard had trouble. After towing her back to the barn and a few hours of gradual tear down found a stripped coupler. I took the one off my 160 with a broken rod (awaiting a repower) and will bring the good coupler to work tomorrow to drill and tap for a set screw. The shaft is a little buggered up but it wasn't too bad with the new coupler. Share this post Link to post Share on other sites
