$400 Forklift blows up on its first job!

In this episode we start by changing the oil on my 1972 Toyota FG 20 forklift. We both this forklift for $400 in the previous episode and got it running. After 3 attempts to get the correct oil filter I determined that the previous owner had modified an improper hydraulic filter to fit the engine oil filter canister. Two trips to the Toyota dealer later and we finally had the correct filter and went ahead with changing that out and getting the correct oil in the forklift. I took it out back for its first job moving a junk Volkswagen Beetle. The forklift moved the car just fine but then proceeded to locking up the engine. Once Jess came home we went out back with the Jeep to pull the forklift out of the beetle that it was stuck in. Once the forklift was pulled out I verified that the engine was stuck with a pipe wrench on the drive shaft. I then used the Jeep to pull the forklift to its final resting spot. I’m not sure why the engine seized so any comments and suggestions would be appreciated! Thanks for watching.
