Unfortunately, I purchased a 1 ton crane for removing and installing the 4.0L SOHC V6 in my 2000 Explorer Sport. At the fully extended boom position the boom was too short to reach the engine center of gravity. I ended up having to remove the front bumper to get the boom chain where it needed to be. Surprising to me, I may not have to remove the bumper on my 2003 Centennial (Ford's 100th anniversary Explorer Limited). The photo below shows the boom assembled according to the instructions. I recently purchased a load leveler for better control when working alone. Routing the chain out of the front of the boom instead of the bottom extends the reach about 2 3/4 inches. Almost enough to reach the engine center of gravity. I can gain another half inch of reach by removing the front license plate mount. The higher the lift, the shorter the reach. Folding the chain within the boom reduced the lift about 7 inches. Since it may take a long time to remove the stock engine and install a 4.6L DOHC I added fuel stabilizer to the fuel tank and took a couple short drives to make sure it was well mixed.
