Talking Re: Best "torque" motor

I put the old D&D motor back in the cart.
Last summer it ran about 22MPH on flat ground and had all kinds of torque.

I sent off to PQ a few month's ago because it started running hot on me.
{I think because of the creek ride it was under water.}

I installed it a week ago and it ran 25MPH and still would pull the front end off the ground when I wanted it to. I had a big smile on my face after riding it.

I got my new PQ motor this past week but haven't put it in the cart yet. Maybe this week. I plan to try both out at the CAW in 2 weeks.

Default Re: Best "torque" motor

The build is done! Well, not sure it will ever be done
48 volt conversion (already thinking 72v ), 6" Jake's lift, 23" tires, 700 amp cntrl, solenoid, FNR, #2 cables, Trojan 875, PQ black widow2 motor, custom paint with a little orange pearl mixed into the clear (for a nice touch in sunlight), and a few entertainment features.
Thanks to Scotty, Andy, and everyone that gave me input. I used site sponsers for pretty much all the parts. Couldn't ask for better people to deal with.
I do have one issue that needs addressed, and I'm hoping someone on here will have the answer for me. The cart has a medium to severe wobble in the rearend. It gets really exaggerated when braking at higher speeds. When the cart was stock, it had a slight wobble. I just wrote it off as a bent rim, since I bought the thing used. I fear a bent axle, but hopefully one of you have had this experience and can tell me it's something other than that.

I would like to find a black top for it, if anyone knows where one can be found.

Default Re: Best "torque" motor

do you have the stock brake drums on the rear, and are you using a spacer?

when i had that combo, i had a wobble when i would step on the brake. when I switched to disc brakes, it went away.

don't ask me why...

Wink Re: Best "torque" motor

Take the wheel off and see if the hub is bent. The studs are hammered in so if they hit something pretty hard it could be the hub is bent are the studs are. Just a guess. If not it's the axle more than likely.

Your welcome for the input. Paint the top black with fusion paint. Wipe it off good with lacour thinner right before you spray it.

villajoe, no spacer and it does it all the time just worse when braking.

Andy, I'll definately check the hubs and look into this fusion paint. I assume it has great adhesion properties and won't scratch off easily.

Wink Re: Best "torque" motor

I painted Andrea's top with Pink fusion last week before the CAW ride this past weekend. It hardley touched it.

Default Re: Best "torque" motor

So I pulled a rear wheel off to check the trueness of the hub. What I'm seeing is when looking straight on at the axle and bearing, when in motion. The bearing appears to be moving up and down slightly as it rotates. To grab the axle and move it by hand up, down, left, right, and all around, it seems snug. Also watching the axle from behind doesn't really show this movement. I'm a little stumpped and looking for sure fire ways to rule out a bad bearing or a bent axle. Both sides do this. What are the chances of 2 bent axles? How much is involved in replacing axles, anything like truck axles?

Wink Re: Best "torque" motor

The axles aren't that hard per say but they can be a pain if bent.

Take hub off pull the snap ring out pull bearing seal out pull inner snap ring and pull axle. The bearings should come out with the axle. I have seen them not come out though then they are a pain.

Default Re: Best "torque" motor

I know my batteries are brand new and have not completed enough cycles to be "broke in" but should I be seeing the voltage drop to 41 volts when climbing hills. If I stop on these hills they jump back up to 50. I guess I assumed getting PQ's high torque motor would prevent this? These aren't "side of mountains" type hills either, and it's on pavement...............It does do better than neighbor hood gas carts on the hills, but was kind of hoping for more. Would 72 volts increase my climbing power or just speed?
