616 Rear PTO and 3pt Forklift

Recommended Posts

It's been a little over a week since I drug home the 616 and forklift I was so excited about, and I have been able to give the machine a decent bath, and managed to figure out the rear PTO install.

 

I had pulled a front PTO clutch and the transmission components for a rear PTO from a freebie 4040 I had.  With some help from Paul, I did some research and sourced some replacement Timken bearings and seal locally.  

 

Another member, Phil, had the intermediate shaft and shaft components parts to help get my front clutch on the rear PTO shaft.  He also had a nice front and rear PTO covers. Here's a few pictures of the results.  Everything feels smooth and after about an hour of tractor operation, no leaks thus far.  I hope to never pull it apart, as the amount of loctite used on anything with threads is frightening.

Next up was undoing the Cat0 to Cat1 conversion on the modified B series forklift I grabbed from a dealer stash in Zanesville, OH.  Story goes, this was modified from it's application on a FDT Simplicity, to fit a 620, and later, a model C with 3pt.  It is now back on a Powermax, but I need to work out plumbing to get it operational.  The original valve was being used to run the lift, and the seller found the original B series pump (which looks new) to go along with.  A member here is fabricating a reproduction forklift (which we should see at the Portage Forklift Reunion this summer), and offered to purchase these from me, to offset the cost of the 3pt lift.  Everyone wins!

A lot of mechanicals there to get figured out.

Great to hear about the progress. 

Yeah, I shoulda slowed down and took some pictures during the process.  I was happy to have my bearings on a Friday and then couldn't leave the shop till it was done.  Hoping my switch is in the mailbox today so I can make it functional.  I need to replace a cooling line that passes by the RPTO shaft with a longer one, to give clearance I'm comfortable with as well.  Picked that up at lunch today.

Josh; will the 3pt. lift as much as the forklift or will you have to be conservative with what you lift and move at the same time?

I don't know how you were able to wait that long to go get it.  The anticipation would have been killing me.

It was a blend of anticipation and fear of 'was this worth it'  sm03

Dave, I'm told the forklift will lift about 500lbs.  I had always thought that that Doubling the cylinders in parallel will double the force on the load.  Since the OEM application will lift 500, and this one has double the lift cylinder, this should lift about 1000lbs.  Does that seem accurate?


But yes, the 3 point isn't up to par with that kind of weight, or at least I don't intend to find out.  It would be handy for moving pallets with implements, etc, especially since it will have slightly more lifting height than the B series.  The pmax 3 point capacity impresses me, but it is also lifting the weight of the forklift.  I"m guessing that the steel removed from the original frame and the steel added to the mast for width and fork length about equals out, so with the extra cylinder and heavier chain, this should be in the neighborhood of 375lbs.  It will weight more when I hang a Brantly reservoir on it.

It's rough to see in the photos, but the dealer also upgraded to a much larger chain, which raises that second stage of the mast, vs the OEM chain on the forklift I have on the B-1.  It's very well thought out.

Josh; I tend to agree with your thought that two cylinders at the same pressure should double the lift force. However.....we both may be wrong&:)
