Thank you, pretty sure I've got a few of those hidden away somewhere!

Hello all, I've been putting back together my new to me MEP-803 after some flywheel repairs and realized it is missing the Circuit Interrupter Switch on the control panel. I sourced the correct switch but still need the diode, Does anyone know what size rating the diode is? TA's just show...

Thank you everyone for all the input and information, I received all my parts so I'm going to put this thing back together and see if it makes reliable power. I'm in the process of building a new house farther back on my property, just poured the foundation and my local electricity co-op just...

Well one thing I realized after 27 years in the military that there's the right way, the wrong way and the government way.

I agree, mine was the same, no pin in the crankshaft side. The LPW4 parts book lists the generator flywheel part number and also lists the part number for the dowel pin, no note on the flywheel about leaving out the pin. I wonder what the difference is between the commercial Lister/Onan genset...

Thanks for the pic's I just actually received in the mail a package with a new crankcase door gasket, factory flywheel bolts and a new dowel pin from Gary Jones of Diesel Electric Service in Kansas who as I understand it bought out the entire Lister Petter manufacturing plant when they closed...

Would you be able to post a picture of the bolts? and a length measurement? I have a really good industrial hardware supplier near me who stocks a lot of good quality metric hardware, I searched all over for the MILSPEC for them, it would give all the dimensions but had no luck on that.

I wasn't looking forward to changing rods in either! I didn't want to have to pull out and taredown the 803, I've already got 3, 1104's tore down and piles of parts all over. I did find out the 803 has had the rods and crank and bore machined, 10 thousands under on crank & rods, 10 over on...

The Perkins is from a different project, TREX skid steer.

I think Monday I'm going to contact Lister and or Onan and see why they don't use a dowel pin in the flywheel ? It wouldn't be to hard to put the flywheel on my milling machine and drill out a dowel hole BUT there is a reason MAYBE that this isn't done at the factory. might be a designed weak...

My guess is the bolts never were torqued correctly, it only has a few hours on it after coming out of depot for the tier II upgrade, Yep, magnafluxing both the drive plate hub and flywheel and crankshaft end is probably a good idea, I'll throw them on the bench in the morning and sprinkle some...

It's a Perkins 1104C-E44T, not the lister from the 803, it's out of my TREX PT-100 skid steer.

Finally got the time to pull this down, juggling 100 different projects, who said retirement would be relaxing? It was exactly what I was hoping for, all the flywheel bolts were sheered off, with no damage to anything, was even able to walk out the broken pieces out of the crank shaft. Whats...

The rods on these engines have different lengths, that's what determines how far the piston sets below the deck. It's real important to make sure you mark which rod came from what hole. It's a Perkins, NOTHING is easy on a Perkins!

Pulling the can today, hopefully will know the results soon, other projects got in the way!

Will know today, got everything tore down just have to unbolt the can pull it out. Got sidetracked, I converted my originally owned 1999 F250 pickup from a 2WD over to a 4WD from a donor 2001 F350 4WD truck, basically made my truck into a F350 4WD with the full auto hub shift on the fly system.

Well I guess I'll know in a few days! I'm in the middle of doing the machine work on a Perkins 1104C, making 1 good engine from 3 bad ones. I'll have to figure out if this DN4M has stock crank journals, don't want to replace rods if I don't have to.

The guy I got it from said he tried starting it, said it started to fire off but then the flywheel just spun, most 4-5 bolt flywheels also use a alignment dowel pin, I'm hoping someone at the depot who assembled the new engine in this forgot the bolts and the dowel pin finely sheared off. Going...

But isn't the drive plate bolted to the flywheel? The engine turns over but the flywheel doesn't move, turn the flywheel through the starter hole and the drive plate/fan turns.

I just picked up a 803A from someone who bought it from auction, Has a new Tier 2 upgrade from 2012 with what looks like a new engine with just a few hours on the Hour Meter. Problem is the the flywheel is not attached to the crank! engine will turn over by hand (Fan blade) and can turn the...
