Pump Fix Saved $1,800
“It was the first of 3 in-line pumps,” explains Nelson. “The backs of the first and second pumps have splines with a coupler to the next pump. They drive the wheels. The third pump drives the lift cylinders.”
With the first pump out of commission, so was the skid steer. Nelson decided to redo the splined shaft. He ground the end of the shaft down so the sides are flat and measure to 1/2 in. by 3/8 in. He then drilled out the flywheel and welded in pieces of hardened steel from other shafts to make a rectangular hole to match the shaft end.
“I tried drilling out the flywheel hole,” says Nelson. “The steel was too hard. I had to heat the temper out first. I would have needed a grinder to get through the hardness.”
Once he had the hole drilled out and added the new pieces, he remounted the flywheel and slipped the shaft into place.
“It works fine,” says Nelson. “I have used it almost every day for more than 6 months.”
