I bought a 1850 diesel with a spun bearing was going to swap a 510 massey 354 into it, I can get the live power shaft out about 10 inches and it hits some thing hard, a friend has 2 of these and his shafts slid out easy on both , a salvage yard friend has put pull tension on them and turned them to get them to line up?? the shaft is not bent. any ideas,Can I unbolt the the 2 speed from the bell housing and remove the engine that way?? I know I would have to support the 2 speed so it would not bend the shaft , as it out 10 + inches it should clear the clutch and bell housing or am I wrong it thinking that , any help would be great.. Thanks Bryan
 
Use a long 1/2" bolt as a handle, about 10 or 12 inches long. I just keep pulling and pushing on it and spinning till everything lines up correctly, some guys use a impact gun to do that but I never tried that way. You just do not have the spines all lined up yet. Sometimes it seems like forever then walk away come back and try again.
 
Thanks, that is what I have been doing over the last 5 days I try it and walk a way, thought that maybe some thing had been twisted or some thing that prevented it from coming out, Thanks Bryan
 
I've had to do the impact wrench trick one time. Apparently the PTO clutch discs weren't quite lined up or something. I got the shaft out far enough to put a short bolt in the hole, put the impact on it, pulled the trigger and pulled on the shaft. It popped right out. The thing you have to remember is that there's a second set of splines to drive the pump, part way in on the shaft,
 
I wonder if Lee Little will show up to tell the story of trying to get one back in.

A couple of weeks of trying it, then an old Oliver guy drove in and slid it right in. LOL
 
The stub shaft comes out, then the o ring. Take a long bolt and thread it in, put an impact wrench and socket on the bolt. Pull while running the impact and it will come out.
 
yes the tractor is on level ground an it neutral should the pto clutch be engaged I have tried it both ways , I have turned the pto shaft while holding in a few inches so none of the splines grab the shaft , and yes I removed the O ring, I can shove the shaft all the way in, I have tried to turn one spline at a time and pull, maybe tomorrow it will pop out on the first try but as of yet no luck . Thanks again Bryan
 
I had trouble on the 1650 once. I made a bit of a slid hammer using a section of all thread and a head off a broken sledge hammer. If your moved 10 inches then I doubt that it is bent. Really no way to bend them unless someone tried to pull the engine with out removing the PTO shaft.
 
If the shaft splines that go into the hub in the back of the flywheel are worn/distorted you may have the issue you are experiencing. I had one in an 1850 like that, I wrapped a log chain around the exposed end of the shaft with half hitch knots, then whipped the slack of the chain to jerk it out. It took about 10 hits to get the shaft out of the tractor.
 
I had one that was damaged like that and had to put my slide hammer weight on a piece of half inch threaded rod.
 
Did you get it out? I have a hint I'd like to share if still hung up. It will take a couple of minutes of explaining.
 
OK this is what I did I slipped the motor ahead about 3/4 in put a wire around shaft put a bungee cord on it pulling up tried to slid it out by sliding on luck . put my impact on the bolt in shaft had a iron, bolt went trough, to use as a lever to increase my pulling power still no luck
 

I don't understand.. you disconnected the engine and tried pulling the engine out? Or disconnected and slid the engine forward? And now the shaft is bound up further?
 
I slid the engine ahead till front pulley hit steering sector about 3/4 inch , by doing
this I could see the shaft between the sprockets I put a wire around shaft to hook a
bungee cord to lift and help a line splines with pto drive I can move the shaft freely
about a foot .
 

Since it sounds like you're going to go through the whole tractor anyway, I'd just pull the hydraulic unit off and see what you're dealing with rather than fighting it any further.
