MEP002A cylinder numbering

[OG]

When adjusting valves on MEP002A, there are A and B marks on the flywheel. Which is the cylinder A? One closer to blower, or the other one?

Thank you

OG

nearist the blower is a #1 cyl.

And A mark is for #1.

nearist the blower is a #1 cyl.

Isn't the #1 cylinder the one closest to the generator head or have I gotten myself confused?

You are confused. The cylinder just behind the fan and shroud is #1. Applies to 003a as well.

I have searched the manuals several times and cannot find a cylinder layout. However this illustration is the procedure for setting the timing mark on the flywheel and it shows setting up the dial indicator on #1 which is depicted on the flywheel end. I have read several post as saying the one closest to the blower wheel is #1. Is there another illustration that contradicts this one? Hence my confusion.

Thanks, John

I found it in TM5-6115-585-34 on page 7-40:

(c) Turn blower wheel clockwise until Number 1 cylinder (closest to blower wheel) is on compression stroke, which follows closing of intake valve.

Yes, that contradicts illustration 7-5 in the same manual. BTW, you have good eyes. I have read (skimmed thru) this several times, as people have said they read it but I never found it. I also believe Jimc (mep-003a teardown and refurb) in his first post refers to #1 as closest to the gen end.

Which is right?

Not such good eyes, just the use of CTL-F in my PDF file viewer to search for "1 cylinder". I think the illustration you posted was chosen to show how to use the dial indicator, and the editor who chose it wasn't thinking of which cylinder he showed, but that's just a guess, of course. And I could be wrong, but it looks to me like Jimc said "cyl number 1, from gen end..." because he wasn't sure which end cylinder number 1 is on. Having #1 at the opposite end from the flywheel is pretty standard for engines though. I can't think of an inline cylinder car engine that has #1 anywhere other than the radiator end.

But I'm doing a lot of guessing, so I pre-apologize if I'm wrong.

I am no longer confused. Page 134-135 in the parts manual identifies the fuel lines to the corresponding cylinder. #1 is in fact closest to the blower.

I guess illustration 7-5 is whack.

OK Thanks. I'll remember that it matches cars.
