Default Swapping out (upgrading) an EZ-GO Electric Motor

Hey folks,

This is my first post - so thank ahead of time for any guidance. I recently learned a lesson by buying a nicely lifted, yet woefully underpowered 2002 EZGO TXT fleet cart. I am using this in the North GA mountains - so it needs more torque to say the least.

I ordered an upgraded motor (through D&D), 4GA cables, 700amp controller and heavy duty solinoid - so I should be set for parts....all I need to do is the work to swap out the old motor and parts with the new.

The project looks pretty straightforward - but I was wondering if anyone had any guidance or words of wisdom that would help me smoothly complete this upgrade?

I assume the existing motor should come off fairly easily - although I read where folks need to hammer off the old motor, after removing the bolts. Will the new one just slip on and be ready for bolting? Or am I underestimating the work involved?

I figure just swapping out the old wiring for new - if done one wire at a time- should be pretty straightforward - although my new contoller may not fit under the cover due to the size of the new one.

What else should I be aware of from your experiences? Thanks!!

#1 - don't do it with the batteries hooked up.

#2 - Wiring - do it one by one....

#3 - Yes - removing the motor is that easy - sometimes the old ones take some persuasion to remove though.

#4 - Sounds like you're on your way to torque town.

You REALLY should go ahead and add 2 more batteries while you're at it.

Yes, your new controller will not fit under the cover.

I agree wit Blue Chip. If your doing all that upgrading you should go ahead and jump to 48 volts. Yoy won't be disappointed

Hey - thanks guys for the speedy responses!

What more can you tell me about the 48 volt conversion? From what little I know that essentially means adding 2 more batts that would sit in the rear club holder compartment. What else is involved - just a couple more cables, or is there more to it than that?

What would the main benefits be of 48 vs 36 volts?

Would this conversion still work with the new motor/controller combo that I just bought?

Appreciate the help!! Can't wait for my parts to arrive this week.

Go to 48v!

I can show you how to do it for about $200:

Thanks for the great photos and detail on the 36 to 48 conversion. It sounds like ultimately the direction to go for sure.

However...based on the $'s I just spent for a new controller, motor, 36volt HD solenoid and cables - I'm thinking one step at a time.

My first step is to install the new components to improve it's performance as a beefed up 36v cart as a starting point. What kind of performance can I expect out of doing these upgrades first - and the 48v later down the road?

Thanks!!

Geezer, without knowing the rated HP/RPM of the new motor, I cannot advise.

Ah yes - that would help - here goes:

The new motor is listed as 19 tooth/57/4.25/series - up to 18 mph / 48volt (from D&D motor systems)

The new controller is a 700 amp (ITS) non-programmable (with notes: short housing)

The new solenoid is a HD 36 volt, 400 amp continuous current, 800 amp inrush current, used with 500-650 amp controllers.

If D&D says 18mph @ 48v then I would suspect you have purchased a high-torque motor. At 36v it will not run any faster than you are going now, BUT, it might climb a vertical wall.
