Need new motors? Grind a gearbox? Adding teeth to a pinion?

Hope some one could help with options for motor upgrade for 24volt 10 year old power wheels Escalade, I was thinking about getting some775 DC MOTORS? But would have to change to the new style gear box 7R, I have researched and the cost after getting ever thing I would be into $250and up. I hoped some one had any other options for just motor upgrade with better torque. Also any body have links for cheap 7R GEARBOXS

You've already upgraded to 24V -- are you using an ESC?

Mltoys has 7R gearboxes for Escalades here, though I don't know if they've changed it over the years.

(This is according to their gearbox reference list here: http://www.mltoys.com/Power-Wheels-Gearbox-Identification-Guide-s/130.htm)

You'd then need two 775 motors and the appropriate pinions. Cheapest 775 motor is the Jameco ones ($16 shipped for 4):

http://www.ebay.com/itm/Nichibo-Taiwan-775-7013F-R-12VDC-Motor-12-610-RPM-4-pcs-/112230651034?epid=503587959&hash=item1a2177d49a:g:i5gAAOSwImRYSaDp

These are good for 33% more torque than stock and you get the larger can size (better heat dissipation, etc.). They can be run with stock wiring. You can spend more and get the Banebots (Mabuchi 8514) for ~$45 for a pair of them but you should invest in an ESC or other motor controller if you're going to run those.

Pinions are another $8-10/ea, so you're looking at a total of $120-$130, depending on shipping. Even if you bought the 775-conversion centering shims from mltoys you're only in $150. If you go with the cheap motors you knock $30 off of that.

But if you're going the 775 route and want more speed, you don't buy the Brute Force/Escalade gearboxes. Get the Corvette gearbox instead (http://www.mltoys.com/Power-Wheels-Mustang-and-C7-Corvette-Gearbox-p/00968-2821.htm), buy a set of the cheap Jameco 775 motors, and two 22T pinions. This should be a 30-35% increase in speed with no torque loss and no additional wiring stress vs. the stock system (motor has more torque, the different gearbox ratio turns that torque into more speed).

Thanks for the help, trying to keep cost down as this is my kids back up car, she runs it on the gas mostly and would like more torque than speed, so I'm going to get new gear box, motor and maybe mltoys steel gear for gear boxes....24v stock wiring, no other upgrades. Whats my cheapest option?

Great you have the determination to take this on. […]
