What types of equipment had the 3-53 and 4-53 engines? I've seen them in gensets and an old fork lift. Was a V series made in the 53 and was there a 6 and 8 cyl??
The old FMC skidders used the 6V53. I've worked on plenty of the 4 and 6V53 engines in Drott excavators. I seem to remember the 6V version to have wet liners and four valve heads but I could be wrong on that. Plenty of the salmon fishing charter boats out of Westport and Ilwako Washington used the 5-53 for mains. I've seen a couple of motor yachts 4 cylinder auxiliary gensets. A long time ago while driving across country I spotted plenty of irrigation pumps on skids at the ends of fields with the little green monsters.
Military used plenty of Detroit's also .
M113 personnel carrier used 6V53 . It was also an FMC product like the skidder that John C. mentioned .

Wow! A lot of them out there. I recently purchased a blower that turns out to go on a 4-53. Having no 4-53 to use it on, I was looking to see who might be a purchaser of said blower. I was hoping to find a buyer in a niche market, but I guess the market is potentially large. From the little bit of research I've done it seems the blower is not a high failure item. Looks like I might sit on this a while!!
