Some shots of the tiller with the tine assemblies removed. I must say these are one of the hardest items I have had to disassemble.
Sorry I did not get any pictures during the process but will try to describe the method.
Soak for about two weeks with blaster several times a week.
Have a torch handy.
With the outer set of tines off I place a 6 inch long extension from a 1/2 inch socket set into the tube.
Heated the exterior of the tube, which is over the solid main drive shaft. Used a large three jaw puller to reach to the square of the tine assembly, with the screw of the puller running inside and against the extension which pushed on the solid shaft.
Then heated and turned and tapped and pounded and heated etc till it moved. Took about 1/2 hour per side. Once it started to move I put a air impact on the nut of the puller and it saved a lot of wrenching.
I believe I can start to remove the covers and see what the bearings and chain look like. I am expecting the worst.
I need to pull the drive pulley too.
Pulled another part from the rust tank. The water was frozen over, still seemed to be cleaning

Wife says I am goofy working on this stuff.
Any suggestions from folks that have had these tillers apart might be helpful?? (No not about me being goofy

)
I did print out the tech manual from the OCC Tech Library. Thanks to Roland for having this available.
One of the curved supports is broken. These look to be cast so I may have to get that welded by someone? I have not tried welding cast iron and do not have the rod.
Also one or both of the covers over the bottom bearing looks to rusted out. That may be fun too!
Will do some whitetail hunting in the morning.
Regards,
Chris
