I picked up a 2010 Terex skid steer at auction for a pretty good price with the full understanding it was underpowered but it runs OK and works for my needs on my small acreage. However, I am thinking of selling it and I can't imagine anyone else would be happy with it as it's way underpowered and won't go above 1700 RPM. Of course, I don't have any contact with the previous owner as it was from an auction but my sleuthing has revealed the following: it's a 4-cylinder Perkins 404D engine. The engine badge reveals the Perkins engine family as 4H3XL2 22L84 and it also has a line on the badge that advertises HP32/1700 and Power 23KW at 1700 RPM. I'm no mechanic but I'm assuming this is an engine from a generator that produces 32 HP at 1700 Is there any advice on what I can do to, if anything, to increase the power? Is it possible to install the after-market 404D Turbo kit? Any advice would be of great help as I live in a very rural area and don't have local access to diesel mechanics. Thanks!
Generators run 1800 RPM and nothing else. 1700 RPM is a strange speed. You would think a little engine like that would run a lot more RPM where they are not locked to a specific 1800.
I will ask a stupid question, is the engine original or has it been replaced?
The engine was replaced. there are some service stickers on the frame and it looks like it was owned by a rental company. My guess is the the engine blew up and they threw in anything that fit and shipped it off to auction. The engine is supposed to be a 404D-22T. The 404 is a very popular Perkins engine used in all sorts of equipment, including generators, which is where I think mine came from.
There is a hi and low idle screws.. have someone move the throttle and have a look at what it hits.. U can back the screw OUT to 2000 rpm’s.. There is also an external fuel screw.. it’ll have a tamper proof cap on it.. The cap is easily defeated with a small Dremel and cut off wheel.. Once u gain access to the adjuster, screw it OUT 1 full turn and see how it acts.. Increasing the fuel WILL also raise the rpm’s.. so if u raised the rpm’s FIRST.. you’ll probably have to turn it down, after raising the fuel..
