Help With WorkTrak 404 29.4KW engine

[greg_g]

Thanks Greg, I probably need a new starter, as noted in a previous post I said the engine turned over slower than I thought it should.

Don't write off the starter until you do two things: take the battery to an auto parts store for load testing (it might be weak). Also, the starter will spin the engine MUCH faster with the compression release open.

I think you might only need a pull knob on that compression release cable, and I'm pretty sure I have one in my spares. Same with the starter, the one I have here might possibly fit your tractor.

Pull that compression release and keep it pulled, hit the starter key and let her spin up, then push the compression release back in. You also can tow the tractor with something and dump the cluth. Drag it around until she fires.

I wonder if she cranks over that slow because the PTO is in gear and implement on the back?

One thing that will surely make a tractor crank hard is having the hydraulic pump deadheading. I've seen a number of times where guys have taken a loader off and neglected to hook the two hoses from the pump together, thus deadheading the pump. Then the tractor won't start because it can't turn over against the back pressure of the pump. Or it does start, and then blows up the hydraulic pump. Something to keep in mind...

IT RUNS !!! Thanks to all. It even ran on its own with compression release engauged.

When compression added, it sounded like a bad connecting rod. Once rpm added it sounded fine. Do these 3 cylinder engines sound that way at idle?

Oil has never been changed. We are talking 6-8 years. Dipstick has a 15* bend about an inch from end. Is this how they are? Oil just barely at end of dipstick.

What weight, and how much does this engine take. Also a filter number would help.

Still will not crank from key. Attached are some more pictures of relay. Maybe it is a starter relay. Found an old one, RED, in a pile of junk. See attached.

Thanks guys, I am one happy camper. It drove a lot better than I thought it would.

Congrats on starting your new friend. Now you know she works, I think it is service time to replace all fluids and filters and some fresh grease.

My 1030 is a 3 cylinder and it doesn't sound much different than all my other ones, besides it reves higher at idle. I may have been the lack of oil in certain parts of the engine, because it was sitting so long with not enough old oil and the head of the engine being dry.

As engine oil you'd have to make sure it is rated for diesel. Depending where you live, if you want to use it for winter, I suggest you use 15W40, 10w40 or 5W40. I use Mobil 1 Turbo Diesel 5W40 in all my newer engines. Just my old Case Terra Track gets Shell Rotella 15W40. I can't get 10W40 Diesel oil even if I wanted to. So 5W40 Mobil 1Turbo diesel at Walmart it is.

Not sure how much the engine takes, but I suspect around 4L since it has 3 cyl. Measue what you take out plus add one liter. Filter numbers should be printed on the existing filters. You should have a fuel, a oil, and a hydraulic oil filter.

Glad you got it running! Definitely time to change the oil, and I'd suggest flushing the crankcase with a dose of diesel fuel after you drain out what's in there. Just put in a gallon of diesel fuel and run it for about 30 second then shut down and drain it again. Then replace the filter and refill with fresh brand name 15W40 diesel motor oil. Take the old filter to a parts store and get a match, or contact one of the suppliers who advertises here and get an OEM filter. It will prob ably take somewhere between six and ten quarts of oil. My 304 Jinma takes seven quarts if I remember correctly.

That does look like it might be a starter relay. Any 12v relay with contacts rated for twenty amps or better will work. Most auto parts stores carry a number of different universal relays.

That's not right. When the compression release is adjusted correctly and operating properly, the engine should not start until you release it. As previously suggested, you may have restricted hydraulic flow too. That noise could be the pump self-destructing. I'd remove the pump, and try again. If that doesn't change anything, we'll re-evaluate.

I think you've got the 2.9 liter engine, so the oil capacity is probably more like 7.4 quarts (plus filter). Sounds like the handle end of the dipstick broke off. That will definitely throw off the measurement. And yup, that's a starter relay. But unless/until you get the compression release working properly, I don't recommend a starter relay less than 30A (and 10ga wire).
