I notice that this is an old thread but do you actually have a source for Jinma Y485 engines in stock? If so, I would like to get a quote on a replacement engine for my 2007 Jinma 354

Steve: Since the injector pump output is very small you need to remove the input pipe to #1 injector, loosen it at the pump input and temporarily add 3-4" of rubber hose to the open end. Now wire it up temporarily so that it is vertical and level at the top. Fill the hose with clean diesel fuel and turn the engine over slowly while watching the fluid that is level with the top of the hose. Due to surface tension, you will see the fluid level begin rise above the hose when the injector begins o fire. Its a small movement but this will give very accurate results. Call a good dealer for injector timing for your engine. There are several differences in Y485 configuration that may cause timing to be changed a degree or two. Good Luck!

I had a similar experience with my Jinma 354. The problem in that case was the return line fitting on the fuel tank. The fitting seemed tight but when the tank was filled to around 3/4 it would seep. Further tightening resolved the problem
