Pulling a command help. (Replacing a triad)

Recommended Posts

jimmystractor

This fall, I plan to pull a command out of a sovereign I have to put in a donor Sovereign that has power steering. Admittedly, I have never pulled a motor out of anything. Can I get some tips, tricks or at least a general walk through of what to expect out of this endeavor? Thanks in advance!

Not all that hard of a prospect.  After some practice, it maybe will take you 20 minutes to remove an engine.  There area a few suggestions to make life much easier.  Remove the hood, don't try to work around it.  Remove the mower deck, although that's kind of a given.  4 engine mounting bolts (in your case, you will also remove a mounting plate used with the Triad), 2 driveshaft bolts, fuel supply, throttle and choke cable, heavy gauge cable to the starter, heavy cabel that is the ground cable to the battery, and wiring harness.  In some cases there may be a few other ground cables that need to be disconnected. In some cases it is easier to remove the muffler, than fight the tailpipe around the frame. 

It seems like ahuge task, but is not necessarily.  Your potential difficulties are throttle and choke cable lengths.  The rest sounds like it's a Command out of a Sovereign, so the real pains, drive shaft / connector and muffler should not be a problem.  Might have to tweak the wiring harness, I am not all that familiar with the Triad wiring.  Good luck!

If you are putting the Command into a Triad powered Sovereign, read the conversion posts already posted as far as the wiring changes, solenoid abolishment, driveshaft differences & shimming.  Otherwise Brett has given a clear instruction on how to remove.  Piece of cake removing & installing them.  I'd much rather do that then split for BGB repair.

One thing I should note is that I have a running donor...command powered Sovereign already. So I plan to steal everything I need off of that one for the conversion.

I think the BGB is a piece of cake compared to changing motors 

I dunno.  If I have a direct engine replacement, same engine, I would be done in less than an hour, in and out, running.  A BGB requires removing the seat pan and wheel/tire assemblies, all the hydro or gear linkage, cone clutch asembly and linkage, drive pulley, drive shaft, splitting the tractor, removing the rear hitch and related brackets assembly, hydro lift lines if that be the case, supporting the tractor front and rear halves, park brake, and then put it all back.  I don't think I could get it all dissassembled in an hour.  But everyone has their favorite things to do! 666

maybe a direct replacement but I am having one heck of a time going from a k341 to a kohler ch20 I have removed the BGB and rebuilt it in about an hour

 

I would sure appreciate a tutorial on that.  Seriously.  I'm sure I'm not the only one who would really benefit from that.  I know of a dealer in IL that can do that as well but they are swapping out the BGB for a fresh one already rebuilt.  Still, that's fantastic.  It takes me about 3 hours to get the tractor split & the BGB out.  Granted I move a lot slower than I used to.  The fastest I've ever had one removed was an hour and a half.  That was a 712H which I seem to remember was easier than the 900 series but I cant remember why.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
