I never seriously considered messing with the threading feed gears, but now that you mention it, I will take a look. The gear on the spindle and the first mating gear are both laminated phenolic/fabric. Wondering if a medium gauge toothed belt and gear combo might not work better for the rest...

Randy, I never did wrap this thread up, so here we go. I installed the new *** 45x75x22mm class P5 unshielded bearings without too much trouble. The unintended press fit of the aluminum belt pulley was fixed so that everything was a "gage-fit" and the pre-load nuts worked like they were...

This is just my 2 cents based on having replaced the bearings on my G0602: Getting the front bearing off the spindle and getting the front race out of the headstock housing might be easy or it might be difficult depending how the fits were originally machined. So before getting the big guns out...

Now that it is apart, how do the bearings feel? It wasn't just a metal chip that got jammed in the roller cage??

Wow, this is getting complex enough where a single cylinder for your ship diesel might be plenty! Lloyd

Darn, I carefully drilled a tiny hole for the spill port, and as I was afraid of, it now spills everywhere, all the time. I'll probably have to make one or 2 replacement pieces to fix whatever I messed up. Not sure what that is yet.

I have the same lathe and had to replace the bearings. Here is the thread. It has some photos, too.: https://www.homemodelenginemachinist.com/threads/quieting-a-noisey-bench-top-lathe-how.35361/ The bearings were more of a press fit onto the spindle and just loosening the locknuts wasn't...

I won't know until I get the spill valve working and can drive the unit injector at operating speed and observe it. Right now the injection timing on the cam is "what seemed right" when I made the cam. For the full 360 degree timing cycle: the injector plunger starts down at about 8 degrees...

I have locked myself in to staying true in principle to the Detroit Diesel as much as possible. The wedge is less untrue than any electronics, LOL. Plus, I think governors are pretty cool. Yup Exactly! Just looked thru my old notes (I try and keep a project notebook) and had calculated that...

Mike, (I am a 9 finger, too, LOL) The bleed method sounds good. Mine currently has no good method to bleed and it is a major pain. Re: the gear pump. Something I have already tried and it works for the low pressure fuel, is to use a single piston pump driven off the crank and synched/timed with...

I am glad you are online! I haven't been this excited about the project in quite a while and I think this is a major milestone. All of the "golden arm" adjustments and fits are gone.There are still a number of potential leakage points but they are mainly housekeeping issues, not functionality...

@The Ignoble Troll It is a bit serendipitous that you started this thread last week. I had set the diesel aside and was working on the Arduino Hall/Optical tach. Your post pulled me back to the diesel and I had to finish up a few things on the injector, coincidentally, incorporating that it...

FindHansen has at least one good YouTube video (among his many excellent videos) demonstrating the wedge adjustment for fuel volume and for timing adjustment. I think it was in a video of his dark green vertical diesel where he has all of the parts laid out and explains them. I am not sure, but...

Excellent discussion, everyone! I am still in the unit pump/injector wannabe group and have at least a half dozen versions of the "so close you can taste it," category in the boxes of failures. Designing to a minimal number of critical sealing surfaces seems to be the most workable goal for...

@ninefinger I agree with Everything you said. The fuel injection is the evil devil in model diesels. The injection system, whether it is a pump-line-injector, or pump-line-solenoid injector, or a unit injector of pump and injector in a single unit, that is the real bugaboo. A few on this forum...
