My customer is finally trading in 2 of their Toyotas. A 7FGCSU15 and a 7FGCU25. The little one has 27,000 hours. The 25 has a lot less but it lived a rough life with a clamp attachment. They are keeping a 7FGCU15 that has 26,000 hours. I've been the tech on these machines since they were new in 2004. I am very impressed with the way these machines have held up. The motors and transmissions are still going strong. I have never done any brake, mast, or fuel system repairs to these units. The major things that have failed or wore out are radiators, hydraulic pumps, starters, hoses, head gaskets, forks, chains, and tires. The one thing that would have saved the head gaskets would have been a engine overheat auto shut down but they didn't have them. They will be getting 3 new Yales. For what it's worth, 27,000 hours X say 55mph = 1,485,000 miles.
