Yanmar’s advice/recommendation for the L70AE (similar to the N, V, or W engines) is to break in using the regular, recommended oil viscosity meeting at least the minimum API-CJ4, ACEA E6, and JASO DH-2 service categories found in the operating manual (the attached manual applies to the L70AE...

Yes, why didn't I think of calling Yanmar directly? Duh...guess I always try to do things the hard way. I appreciate the advice. I will call tomorrow for sure.

Interesting - I went and grabbed my Yanmar L-A operation manual - and it says to follow break-in procedures for the first 20 hours - and to avoid heavy loads. But I can't find any mention of "special" break-in oil. I may have seen the 100 hours and arguments about oils in these forums. Also...

So, after two years, finally got my MEP-016D Yanmar engine rebuilt - I procrastinated getting it to the machine shop, and then the shop took forever. But, got the rebuilt engine back and reassembled the generator. After struggling for a short while with non-start and then backfiring, I found a...

Ohhhhhhh…count me in!!!

Checked it, and there is a slight noise at the top and the bottom, but no "thunk" or pause of cylinder movement. It might be something else? So, I've been looking over the parts catalog and service manual, and doing some thinking, and wondering if anyone can give me some guidance. Here's my...

Thank you, Ray. Before I tear into this thing, I'll definitely give your suggestiona go (at TDC and the slight movement to check for play in the bearing). Do you think this the lack of play is enough to determine that that the bearing is good or bad? I would like to assume that all of the other...

I've pretty much come to the same conclusion that you did - that the last time i shut it down, it started back up with no problem because it was hot. I've accepted the fact that I will have to tear the engine down, and I am hoping that all of the bearings and internals are still good. I had...

Three months later, and I finally found time to pull the cylinder head off my my machine. Took about 20 minutes. Seem like warm days always had family functions, and I was left with cold days...like today. So, here are my observations: - I did not see any discoloration on the cylinder wall -...

Indeed, this genset is equipped with an electric starter. I have never used it, mainly for two reasons: 1. This particular engine has always started with the recoil starter, even in the coldest of temperatures. My last oil change was in February 2021, and I remember that time. It was COLD...

I was afraid that might be the case. Nothing is ever the "simple" fix! Well, I'll be pulling the head to see what's going on first chance I get. I feel like this machine is worth putting some money into - what are your thoughts on that? But still can't figure out why I'd have a failure like this...

So, here's the latest in the MEP016D saga... I rotated the engine to the point where both valves were closed. I am assuming that it was at the top of piston travel. Had my compressor set to 60 psi, and applied pressure with a pipe wrench on the crankshaft to keep it from turning (took off the...

I didn't even think of compressing the cylinder with air. Definitely going to give that a shot before I pull the head...Thank you for that advice!! As far as the strainer, I had mine out and cleaned at last oil change. It was in good shape each time I've pulled it, with very little fouling..but...

Oh, Yah...didn't mention that part of the investigation. Once I knew I had fuel, I pulled the valve cover off and slowly pulled the cord. Rocker arms rocking and valves are operating (nothing stuck). I also checked valve clearance and the intake valve was good at 0.15, and the exhaust valve was...

So, I've had my MEP016D for nearly 10 years. It has been with me through a derecho and countless other power outages. got it with 1 hour on the meter (if I remember correctly). It has always started on the second pull, even in freezing weather...until now. I've kept up with maintenance, and...
