Whether you buy a used car from a dealer or an individual: Test drive the car under varied road conditions â on hills, highways, and in stop-and-go traffic. Ask for the car's maintenance record from the owner, dealer, or repair shop.
Other top-loading washing machines can spin as fast as 1600 rpm, although these models are usually more expensive. While spin speeds fluctuate by manufacturer and model, most top-loading washing machines have spin rates of about 800 rpm rather than 1600 rpm, which are rarer.
For example, if a 6-inch water-pump pulley is used in conjunction with a 7-inch crank pulley, the pulley ratio is 1.16:1. So for every 1,000 rpm the crank pulley spins, the water pump would rotate 1,116 times. Since the water pump spins at a faster rate than the crank, itâs said to be overdriven. Flop things around, and the water pump would spin slower than the crank and be underdriven.
