And when you remove the shaft, make sure make it doesn’t leave an old o-ring way down in there where it’s hard to see… I learned that two o-rings are not better than one and would up rebuilding mine twice. Also, a new screw is very tight in a new shaft and doesn’t cut new threads easily. Mine broke and I wound up re-using the original screw.

I had problems with the HEIC files several years ago when Apple made the switch, but not recently. At that time Microsoft had a HEIC decoder that could be added to windows through the Microsoft App Store. Android 10 should deal with HEIC natively https://www.androidpolice.com/heic-files-open-android/ Maybe need to update Android if the HEIC files are still a problem?

Eek. 40ftlb sounds like a lot of torque. I didn’t attempt to put a torque wrench on mine.

It’s not a fun job. I would up rebuilding mine twice because I didn’t check real good and left an old o-ring stuck down in the bore. Working with my head right up against the slobber tube. Took a lot of washing to get all the nasty black oil out of my hair. Ugh

Have you tried our parts list? I’d bet it’s in there. W

Not the same engine (isl), but I drained about 4 gal when rebuilding my coolant filter valve

The “procedure” is basically drain and refill. My OCD requires a flush with distilled water also, but Cummins say’s that is not necessary. You asked what everyone else is doing… and I think a lot of us use an extended life HD coolant that is much better than what is spec’d for the generator, and then pretty much never change it again. If you want to continue to use conventional coolant, probably best to follow the maintenance schedule for conventional coolant. W

My clunking was broken off upper shock mount stud.

There seems to be a misconception that any "float" stage will continuously force current through the battery. That's not the case with lifepo4. As long as 'float' voltage is at or below the resting voltage of the battery, it'll just hold that state of charge and current through the battery will be zero.

As I recall, magnum disables temp compensation ONLY in the lithium profile and there is no option to disable it in custom settings or any other charge profile. I think I called tech support to confirm that. Been a few years… Yes. I’m using custom settings that are a form of cc/cv. I have significant voltage drop in my ridiculously long cables, so my settings are partially to work around that limitation

Yes. Temperature compensation works by raising the voltage by some small amount per degree below 70deg F. That will crank the voltage ABOVE your set point . Lead acid batteries will tolerate higher charge voltage when cold. I discovered this one cold morning after fixing my long-time nonfunctional temp sensor.

When docked, I actually don’t use the magnum “lithium” profile for this reason (mainly…). I have the float voltage set to maintain about 50% and once the battery voltage falls to that point, the charger supplies whatever the load is. Lifepo4 cells have a maximum voltage of something like 14.6v (3.65 x4). So if the voltage set point is lower than 14.6v, the battery won’t be overcharged. The battery will last longer if not held at a high voltage, but float voltage cannot drive current through the battery if the battery resting voltage is at or below float voltage. Something important that I forgot to mention earlier…. The battery temp compensation should be turned off, or if it can’t be turned off (ie- magnum charger), then unplug the temp sensor. Otherwise in cold temperatures it will crank up the voltage set points.

Float is a voltage set point. If float voltage is higher than the resting voltage of the battery, a current will be induced. This is the case with a lead acid battery. If float voltage is lower than the battery resting voltage there will be no current. That’s what happens with a lithium battery. The lithium chemistry doesn’t need to be float charged, and the battery lifespan will be shorter if continuously held at 100%. That’s why a lithium charge profile will end without holding a float voltage.

Tom: do you have a lithium battery??? Just wondering if you have skin in the game

Something went haywire with the xantrex built in AGS. Every time I would start the generator, the AGS would shut it back down. That was the primary motivation. Thought that might be a sign of bigger failures in the future. Plus I wanted true sine. Did lithium and solar shortly after replacing the inverter. I never really looked into how customizable the xantrex charger is
