WOW That about the size of a traction Motor in a 4000LBS lift truck. At 48 Volt we have about 30-40 HP
That motor will really get you and the batteriesssssss down the road.

Any way back to reality, went looking for battery's Wallmart has group 27, 120ah, deep cycle batt. $107 can. each.
Need 3 of them, this size would fit in the engine bay without too much butchery being done. I want this to look like a MF10 with battery's instead of an gas engine when it's all done.
Any body up near me got a line on battery's?

If you can find an Interstate Battery jobber ask him for rebuild batteries.
Interstate does refurb Batteries that come back under warranty and can be reused.
Price about 30 -40% of new.
I use then in my forklift with great results.

Thanks for the info about the rebuilt batteries Ducky. I never knew they had rebuilt batteries, worth checking into.

:ditto:Never thought of that, probably get a better grade of battery too.

Maybe rebuilt is the wrong term.
The way my supplier explains it is they check all returned warranty batteries and the one that were diagnosed wrong and the battery is still serviceable they will sell them at a reduced cost. They do a load test and recharge the battery fully. You will probably have to do that though a local distributor.

Today spent some time on the electric Massey and got the motor mount sorted out.
Pictures show what I did.
Cut drilled and fit a piece of 1/4" plate and bolted it to the frame.
Removed all the shims from in between the rear vari drive pulley and ended up with about 5 3/4" dia. with 1/2" A section belt or 6 1/2" with 5/8" B section belt.
Front pulley is 3 1/2 made for B section belt (5/8"), 3" for 1/2" belt, this 3/4" pulley does not fit the 5/8" motor shaft but used it for test fit. Need to get proper shaft size pulley.
The tensioner pulley needs to be moved rearward 1", have to shorten the arm to do this, the bearing in this pulley is n/g so when I buy another one I'm going to get a smaller dia. pulley.

You can see what is here is not quite right but it show's me what's needed to make it work, it's good that I can reuse the trany pulley and the tensioner that it came with. Can also adjust the rear pulley to smaller dia. by putting shims back in between the sheaths. Could not mount the motor more forward as the implement lift is in the way, electrical wires attach in between the motor and the trany protected and out of the way.

Doug, it sure looks like you are on the right track.
Thinking about this again you will be using the tractor trans for F/R.
You only need to turn the motor in one direction.. No need for those F/R contacts.

This tractor came with a foot clutch-brake and parking brake, the vari-drive handle changes speeds and has a park position. I have removed the vari-drive parts and clutch but kept the parking brake.
So now I have a foot brake and a parking brake, it can stop.

Went to the Barrie Auto Flea market and picked up a 36 volt batt. charger today $50. Found another one for sale for a Tennant floor sweeper shortly after for $125. I think i got lucky finding the cheaper one first.
Tomorrow looks like a rainy day so will see how much I get done on the electric Massey.

Picked up 3 new group 27 deep cycle batteries today and that's about all that got done.
Turned out to be not a rain day so spent some time pruning and cleaning up the yard, got to keep the place somewhat tidy.

Doug
Sorry for not getting back to you.
Thought I have already sent this.
Conversion Kits
Our controller and a conversion option.

Could not find any wiring schematics for you GE controller.
See if you can find a dealer for that cart and they may have some old info at hand.

No problem, Thanks for the help that you have given, remember it's a hobby and it gets done when it gets done.
From what I've been able to find out the controller that I have is for motors that have regenerative braking which I don't have.
I found a guy in Toronto who build's and sells controllers, going to try him, if I get to the point where the tractor is finished minus the controller I'm going to make a 2 or 3 step resistive unit just to get it moving till something better comes along.

Wow, Regen is not all that old. I knew it it come around in the late 80s on the EV100/200 systems. Before that it was call plugging on the EV1 system and actually used current from the battery to try to reverse the motor rotation. Regen will turn the system into a generator the the torque to turn the motor slows the unit down.
I have tricked EV100 control cards to operate without a regen contactor by just putting in the regen current sensor in the circuit so the controller sees the resistance and thinks the circuit is ok. Then it will function great just do not have regen.
