punk dig....no rear drive???

[lil' lucifer]

hey guys, had the punk dig for a bit now. other day it cut out on me. I only had front wheel drive.

I soldered all the conections on the dig again. I even soldered the wires to the rear motor again......

here's the kicker!!!!

when I slightly turn the rear wheels by hand all of a sudden i have rear drive. but as soon as i stop no rear drive again till I barely turn rear tires by hand again????

what do you thinks going on??

could i be the rear axle??? grease sticking or something.

have you tried to unplug the punk dig from your tx and see if all 4 wheels spin?

[lil' lucifer]

i pulled the rear motor from my bully axle. It seams to be the motor its self...... if i give it gas and turn the pinion on the motor one notche it starts working. as soon as i let go of gas stocks and wont start again....

is my motor due for a rebuild? its a 45t novak

Sound like a flat spot on the Comm..had the same issue..thought it was the gear set so I rebuilt the axle and guess what.... pulled the motor apart and there were four flat spots from the brushes hanging. I had mine cut and use it as a spare

I agree, i actually went through this just last week. Thought it was my Punk and come to find out i broke a brush wire. But the wheels would work if i started them by hand.

It sounds like a stuck brush to me. When it has this issue, pull the brush back a bit, then let it go. If it starts running, then you might need to cut the comm and replace the brushes.

I'd agree! Pretty common issue.
