I have a Y385t that I had to replace the injector pump on. I followed the basic concept of finding TDC and injector pump #1 port on the up stroke. Had a lot of trouble getting it close.
After getting everything in the ball park I was going to replace the timing gear cover for the injector pump. I finally noticed timing marks on the timing gear and the counter gear.
Can any body tell me how they are set when the injector pump is timed correctly. ( my timing gear is no where close to the marks on the counter gear; And the timing gear has 2 sets of marks (one 0 on one tooth and 2 0's on a pair of teeth. I am NOT familiar with diesel injector systems and their operation so I need all the help I can get to set this up right. I've got the engine running but I'm not satisfied with it's performance at this point and I'm sure there is something I need to do to get it right.
