Welded-Up Differential Boosts Golf Cart's Traction
"I use an old electric golf cart to haul stuff, and as a mobile work bench. Unfortunately, the cart used to get stuck a lot. The problem is that on loose or slippery surfaces, one wheel would spin," says Malloy.
"The previous owner had tried using larger rear wheels, which only helped slightly. I tried softening up the front suspension, which also helped a little. But the golf cart would still lift one rear wheel on uneven ground, the differential would slip, and there I was, stuck. I couldn't find anyone who made a posi traction unit for the cart."
One day Malloy got so frustrated he decided to just weld up the differential, resulting in a solid rear axle. "I knew that would fix my problem, but I was worried the cart wouldn't turn as sharp or might tear up the grass. However, I couldn't be happier with the results," says Malloy. "The cart turns just as sharp as ever on grass and dirt, with no damage to the grass. The only time I notice anything different is when I make a U-turn on a paved road. Then I can hear the inside tire scratching."
He took the transaxle apart, and stick-welded the spider gears in the differential to the yoke at four different places. "I made the welds easily accessible to grind out in case I didn't like the results. However, after three years I haven't had any problems."
He's used an electric meter and GPS to calculate that it costs about 4 1/2 cents per mile to operate the golf cart.
