    I got the thermostat, heat exchanger, coupler and impeller in today. Everything went in with no issues. The hand pump worked perfect to bleed the coolant. Before I started I removed the reservoir and dumped/cleaned it out. I also removed and cleaned up the all of the grounds and power wires, gave them a coat of terminal protector. Hopefully tomorrow I’ll replace the plugs and get the sound shield back on. Once I start it up and run it, I’ll change the oil and filter. Hope the pictures help.

    I’ll also try and get the fuel filter changed out tomorrow.

    Honestly I’m somehow most excited about the box itself - it will be great for safety equipment!

    Yes, I just picked up a box like that at Harbor Freight for my safety items. Will definitely come in handy.

    I bought that kit many years ago.  I use the box to keep most of my spare maintenance parts.

    So what is this kit you speak of?
    My frame and pan for the Genny is about to turn into dust...just about to the point to just get it out of there...

    They should’ve made the pan out of composite, luckily mine is in good shape. I see the new AC units have composite pans.

    Changed out the plugs and fuel filter. I’m not sure if the correct plugs were in there, huge difference with the electrode compared the the new ones. The new ones are BPR4ES (6587) the old ones were PGR5A-11 (3537). Or were the old ones just worn out?The fuel filter is in such a bad location, but doable.

    The old ones were definitely the more pointed plugs and not worn, but I think they were not correct, the new ones are the right code. Nice work on the fuel filter, I eliminated mine because I had one mounted to the wall..... per BDs advice....

    right plug:

    If anyone is replacing the fuel filter, loosen the clamp for the fuel line at the barb. Do not remove the hose. Use a wrench to back the barb out of the filter letting it spin in the hose, then remove the filter. To install, spin the filter on the barb fitting by hand then screw the filter in the generator. Tighten the barb fitting some then snug the filter down and then snug the barbed fitting and tighten the clamp. Also use pipe sealant on the threads. Hope I didn’t confuse you!

    I got rid of that in-line filter. PITA to get at. Just use an inline Racor filter now.

    @aero3113 Fantastic photos!  I don’t have the mechanic background that so many of you have on this site.  But I’m learning so much from reading here, and the pictures add so much.  Certainly gives me the confidence to do a little more of the work than I might have done otherwise.

    Regarding your spark plugs, I did change mine the 1st year and the old ones were even more pointed than yours.  Felt I was really doing something good there.

    Thanks @Spyderweb , pictures definitely help understand things. I take them for myself for future reference, I have a dedicated 330 photo album. Makes sense to share them!

    The plugs with the point are Iridium plugs. Iridium is a mineral that is very high on the hardess scale. They don't foul out as easy.

    What did you gap the plugs to?

    I’ve always bought NKG for the 5e and never gapped them

    The NGK’s last longer IMO. BPR4ES is correct.

    That’s good to know @Black_Diamond , I’ve read that the generator likes to go through plugs.

    Lame question of the day - how do I get the sound shield off?!  I removed the two bolts from the top panel (at the rear edge) and the single bolt from each end (near the top edge).  Do I need to get rough with it?

    Thanks!
