With all the people worried about your nail polish, nobody mentioned using jackstands would be a bunch safer than just a jack when wrestling these heavy motors around. Good job! Nice cart!
Excited see the new video! You inspired me to update my programming on my new controller. I went with the 600 amp alltrax. Live in Pa with lots of hills. The D&D hi torque was a must. Had to upgrade to 1 gauge copper wire because I was getting a heat issue at the forward/reverse switch. Always enjoy your videos. Thanks
600 amps?!? That's a monster to pair with that motor! I freaking love it. Can't believe you had to go with 1 guage to handle heat at F/R. But that makes sense, to be honest. Appreciate the comment, happy riding!
Excellent video!
nice organized tool box. Inspiring build. I gave it a go and I rebuilt my golf cart from the chassis up. I put in a 5kw 600A Navitas AC motor kit, wow!!! The speed and the torque. 36Mph and hill climb. I put in a LiFePO battery that can deliver 240A continuous and 540 peak for 6sec and it only weighs 111lbs.
That battery change is awesome and is next on my list of upgrades! What a fun project and 36mph! That's incredible!
Great video. You can tell that you really know your stuff. Thanks.
Thank you Matt!
great job explaining thanks so much
You're welcome!
Awesome video!!
Thanks so much!
Great video!!!
Thanks David!
Great video. With more torque and the same voltage I would have expected lower speeds. I too would recommend going to Li-Ion batteries. The weight savings alone along with the higher current availability and longer life definitely make it worthwhile.
Thanks. I'm considering that for the next go around. But my batteries are still less than a year old.
Did the D&D connector not mate with the factory EZGO speed sensor harness? I am doing a swap in the next week myself and I see the EZGO does have a clip in harness for the speed sensor wires further down the loom. If so you can avoid the solder and splice.
If I disable the OBC or On Board Computer
on my 2006 Club Car Precedent, can I use a
LINKS Series charger EPS by Lester Electric
to charge my cart?
A girl with all the tools. You are AMAZING! Thank you.
I may have a tool or two 😉. Thank you so much 🥰
@@AndiWofford Your welcome Andi, take care.
Where can I get info to upgrade my CT & T ezone 48volt Cart
ok so this video is super well done.
Thank you! I put a lot of effort into producing these and it's really nice when someone appreciates that!
Should have bought a "Plum Quick" electric motor. They hold the Geniss world record for the fastest golf cart in the 1/4 mile 100+mph
Did you install a new controller ? Or just replaced the motor straight up ?
I did install a new controller: 48400 Alltrax Controller: amzn.to/3PZHk40
golf cart mechanic here dont cut your speed sensor cable there are two snap rings one holding the speed sensor and then one holding in the magnet to the speed sensor just fyi but still very good tutorial
That's awesome to hear coming from a golf cart mechanic! Thanks!
its a shunt motor, sep. exc, icrease the motor field = torque, decrese the fieds= more rpm, no more then 20%
Hi,
I'm interested in installing new rear differential gears. I live in a golf cart community and the speed limit is 35 mph
around the neighborhood. Have you considered that option? Thank you for your videos.
Thanks,
Shawn T
Hey Shawn! I can't tell you how much I love this idea! I just started googling some parts - looks like for about $430 I I can snag a High-Speed Gear Set Kit (Fits Select E-Z-GO / Yamaha Models). That might just be the ticket! I have to tell you though - I'm not sure I'd do that on a stock motor. But a nice torque motor might be fun to upgrade from a 12:1 to am 8:1
Andi Wofford Ph yea! You would absolutely need the high torque motor! Plus as many as 48 volts! My wife’s cart is a 2018 TXT 72 volt, than can actually lift the front wheels off the ground maybe an inch and leaps off the line. But after that? Not very much except for not slowing down on hills, but 25 mpg on my phone is all she wrote. That would be a great candidate for re-gearing. But borderline dangerous IMHO, due to the fact of having only rear mechanical brakes! My cart in the other hand is a 2018, Tomberlin SS Coupe, 48 volts AC, that’s the best most feature filled carts on the market! With four wheel hydraulic brakes, with drilled an slotted front disk brakes! Independent coil-over front suspension, with trailing arm coil-over rear, 8, 6 volt T105 Trojan batteries, with a built in Bluetooth monitoring charger. Plus all DOT controls with LED lights, digital speedometer and odometer, automotive type key an steering lock, with hi/lo F/R toggle controls up across from the turn signal hi/lo beam controller, plus power steering! DOT safety glass windshield and wiper! The cart handles like a go-cart! With 245/50-12 radial high traction tires, with a limited slip differential! Helps me go just about anywhere! But it’s the tq plus speed that’s great for a stock cart! Tomberlin also has the quickest 0-25 mph time, with the occasional 26,27 mph, depending on charge. I have also driven around our beautiful 55+ community in Central Florida, called Solivida, where the speed limits are between 15-25 mph, with plenty of cart, bicycle and pedestrian concrete 8’ paths all over, with two tunnels going under main roads. I would love to be able to re-gear my cart, mostly because it has the brakes to help stop it from 30-35 mph.
Would it work with the stock controller? I'm putting atv tires on my golf cart because im taking independent suspension off of an atv and replacing the front suspension so i need more torque but I don't have the money to buy both controller and motor.
I've heard of people doing that in some cases, but I would probably look more towards a forum for golf carts to answer that question than a video. Might take a while to get an answer here. Sorry.
@@AndiWofford ok, thank you.
What is the Voltage of the old motor. ? I have a 36Volt system will it work ?
Yes, the old motor was installed factory at 36v. But I was on borrowed time with that controller and voltage on that factory motor. It was eventually going to give out (most likely by overheating) in time.
Is that an AUBURN Sticker on your dash??? War Eagle
It's an Aubie sticker, and yes, War Eagle!!
I cringed hard when I saw you clip the speed sensor wire. There's a snap ring around the sensor holding it to the motor. Take out the snap ring and the sensor is just magnetically held onto the motor. For a few bucks you can get a new speed sensor cable with the proper connector for the new motor.
Great advice, thank you!
always torque your battery connections to 95 to 120 inch pounds. you can experience a battery terminal melt down if you dont
Good call Patrick - I read the recommended torque for these terminals is 95 - 105 in-lb. (7.9 - 8.8 ft-lb.)
@@AndiWofford it a very common thing we see in our shop
Did you post a video on how to convert to 48 from 36?
I did - it's here: czcams.com/video/rY6zfAyGM9U/video.html
What wheels and tires are those?
These are 23" tires from Steeling manufacturing in South Carolina. In my golf cart upgrades video I link to them. But here's some similar wheels: rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&pub=5575460613&toolid=10001&campid=5338441563&customid=&mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2F233073620019
I have the same cart , motor , controller and I am having trouble with getting any faster than 15 mph , and alltrax is telling me that motor will only go 15 , I’m so frustrated
What about voltage? Are you at 36 or 48?
Andi Wofford 36v
What size tires? If you bump up to 48, you'll get more speed, and if you up there gear ratio to 6:1 it'll be faster as well.
Andi Wofford 22 inch tires , batteries are only thing left to do to get to 48v but been waiting due to current set are only 2 years old
Same boat here. Batteries are only a year old now and I want to go lithium. I'll sell you my Trojans 😂
whenever you put higher torque motors in golf carts you typicaly loose a fair amount of speed.
I'm looking for used stock motors if you have any
I do have my one that I replaced. Still works, just upgraded
Love those beautiful hands 🙌
When changing to a torque motor, your speed will drop. If your looking for a faster cart, you need a speed motor.
Thank you, very true.
YOU FORGOT TO MENTION PUTTING THE CAR IN TOW BEFORE YOU DISCONNECT THE BATTERY :)
Do you "drag" race with your cart?
Great content mate.
I think all mechanics should paint their nails red to hide dirt, oil and grease on the nails,,😎 lol
I know I am being petty here but those are not 7/16 inch bolts they are quarter 20 bolts.
A 1/4-20 has a 7/16 head on it
Is there a reason your wearing nail polish?
Does this guy know his wife is digging around in his toolbox?
It's not a "Laser Thermometer" it's an Infrared Thermometer with a Aiming Laser...
