Hi,
The engine in my 2007 554 Jinma is the Fujian Lijia SL4105ABT and it runs well. Don’t have too many hours on mine as I use it mostly in the winter for snow clearing etc. I don’t know if the engine design is original or not, but it sure does work well.
HTHDon't forget to change out the fuel filters – on my 554 there are two of them just above the injector pump. They could well have a lot of sludge or similar in there. Renewing them will at least show you have new fuel filters (i.e. clean).
Sounds to me as if your fuel injection pump is dirty – maybe rust inside. Try working the fuel rack plunger back and forth by hand for a good while. It might be something like it is gummed up with varnish ? Try putting some fuel treatment into the fuel before you run it again. I also suspect that the governor is possibly sticking.
You should drain all the old oil and diesel out of the injector pump and refill with new engine oil or similar.
Let us know how you made out please.
That is fairly normal.
Just drain the injector pump (there should be a drain plug at the bottom) and refill through the top vent (mushroom shaped). You will likely need to unscrew the vent – in my case a 9/16″ wrench worked well. Refill with 30wt engine oil or whatever the manufacturer recommends.
Try using a small bungee cord. The elasticity will keep the pressure on the valve while working and you can always move the lever back with the bungee cord still attached. Won't fix your situation permanently, but will allow a work around.
How about using RV antifreeze – it is safe and does not contaminate potable water systems. Buying in bulk would likely reduce the cost per gallon and is completely safe. Not sure on the corrosion aspects, though I would guess that it would be good.
Is the belt driving the alternator tight – not loose enough to slip at all?
My experience with regulators on my Jinma has been limited. I did find that the regulator was plugged into the strip holding the fuses – yours might be similarly situated. Also if you find the regulator, check that it is properly inserted (mine is a plug in unit) – I had to put a ziptie around mind to stop it vibrating out slightly – enough to affect the voltage output. I have replaced my regulator and if memory serves, it was around $20 or so – quite cheap really.
Might be better to go to another larger alternator that could give you more power than you need. The Chinese ones tend to be marginal where output is concerned. I will check the one on my Jinma 554 if that would be of any use.
Hi Peter,
Just found your post.
Yes, Tommy at Affordable has them in stock.
No more breakages for me so far – touch wood. I did try welding the first one that broke and I managed to get 30 hours use out of it before it broke again. However, by that time I had managed to get another so it wasn't an emergency any more.
Both of the broken steering knuckle showed signs of cracking for extended periods of time – part of the casting was rusty. Whether that was from excessive use on my part or poor casting work, I'll never know. That being said, I am more careful these days.
When you put the new steering knuckle one make sure your tow in on the front wheels is to spec. I would also check and strengthen the tie rod by putting a steel bar inside the tube to stop it bending.
Hope all works out ok for you.
Cheers

You could try cleaning the tach pickup that is screwed into the flywheel housing. The pickup is magnetic and picks up small metal particles, iron filings etc. as well as get doused with oil. Maybe all it needs is the pickup to be t aken out, cleaned replaced and set up. Won't cost you anything and well worth trying IMHO.
Hi Mike,
A couple of things come to mind for me.
1) What sort of gauge are you getting your readings from – electric or mechanical?
2) Oil pressure regulating valve adjustment – does it need resetting with a proven known reference pressure gauge?
3) If electrical, transducer may be failing and giving your faulty readings.
I know you had an oil pump failure so lets start with the basic.
Install a mechanical gauge if you don't have one and prove what the oil pressure actually is.
Check out the oil pressure regulating mechanism – maybe a weak spring inside ?
If these few don't help come back and we can thrash it around a bit more.
Let us know how you are making out – nosey people want to know 🙂
HTH
