A few decades ago now I picked up a couple of ABU-Garcia Ultra Mags, an UM II at a yard sale (for $5!), and an UM XL Plus at a flea market (for $6!). Thought I would share my servicing of them.
The Ultra Mag II is a 1982 model, the year that ABU-Garcia introduced magnetic cast control to the burgeoning American bass fishing world. I've read that this feature was actually first released in Europe in 1980, receiving an engineering award in Germany that year. The UM II is a standard spool model while the UM I has a narrow spool. The UM XL Plus is a 1984 narrow spool model. The "XL" refers to the quick change spool and the "Plus" refers to the Fast Cast (thumb bar FS release). The spools on the '82 UM's can be removed quickly as well, having a removable tailplate. The UM's also feature internally adjustable magnetics -in addition to the external adjustment dial- accessible via the removable tailplates. Integral screws in the I and II, and the screw off cap on the XL, allow this work to be accomplished out on the water without fear of losing screws.
Both reels shown in this tutorial are totally stock, except for: a pair of carbon fiber drag washers and an extra pair of magnets in the UM II. Metal to metal contact areas in both reels were polished with Flitz and a Dremel.
At first look, the internals on these can be somewhat intimidating. Turns out they're not difficult reels to reassemble, but there are a fair number of parts to keep track of. Photos along the way and a schematic can be helpful in places. I was actually impressed at how easily the "layers" could be reassembled. With the small springs and tiny clips, I played it safe by using a magnetized screwdriver and even adding a stack of rare earth magnets to the shaft of the screwdriver.
This post is something of a tutorial, but I did not photo every step. Instead I'm sharing my reference photos, taken to remember the order parts go. I recorded the order of washers, the location of shims, the orientation of gears and springs, and the more complex mechanisms such as the freespool and the levelwind. Hope these help, in addition to your own photos, if you decide to dig into one of these original magnetic ABU's.
These reels both use the ABU Ultra Cast spool design (the predecessor to the newer "Ultracast" spool design), in which the spool shaft is independent of the spool itself. This is somewhat unique in bait casting reels, although not entirely a new concept as both JA Coxe ("Cross-Bolt") and Shakespeare ("Tru-Axis") used it in some of their direct drive reels.
Finally, the magnet arrays are adjustable in the Ultra Mags, via a screw that raises or lowers the spring loaded array, increasing or decreasing the magnetic effect. I standardized the setting by zeroing the dial on the tailplate, then tightening the adjustment screw until snug. This seemed to make the array plate un-level; Backing off a tiny bit leveled it. I also added a pair of rare earth magnets to the array plate as an experiment. Final adjustment will be done during a casting session.
When my UM II was first reassembled, I found the levelwind line guide would not free-float as it was designed to do. Opening her back up revealed that I'd forgot to place the freespool to levelwind linkage rod between the two studs that line it up with the rotating plastic levelwind block that rolls the line guide hold over, freeing the guide during a cast. Easier thing to miss than describe! See photo.
The second to last photo is of the UM XL Plus. It's essentially the same animal inside as the UM II. (In fact, it's pretty much the same animal the ABU round reels of the same time period). The "Flippin' Switch" feature, that provides freespool only as long as the thumb bar is depressed, is simply a plastic block that stops the full engagement of the freespool mechanism.
Again, hope this post helps or encourages some who have or find one of these nice reels collecting dust somewhere. I've caught a lot of fish on mine.

FINI!
These are cool reels!
Pretty sure Gfish is a fan of these 8)
Great reels I have the ultra mag xl plus and the XL V. Both very cool. The small one is still on the to do list.
Yeah, cool. I always liked that long skinny rod that goes most of the way across the brake plate and pushes the levelwinder back into a "pre-lock" position. Looks kinda stupid and cheap, like you'ed see on a low-end reel, but never failed on my XL plus or my XL V. Wish they'ed come out with a modern version of these, maybe with aluminum side plates.
Yeah, it appears that plastic parts are ok in certain low stress areas. The nylon gears that activate the LW have held up too.
Here are a couple of the harder to find assemblies for that Ultra-Mag.
Just happened to recognize them as I was sorting the ABU parts.
Best, Fred
Hi, Fred. Yes, that's it. 975392 is shown on all the Ultra Mag schematics I've looked at.
UMag doing its thing, quite well.
Chunky!
That there is a lap full of bass! :))
Nice "bucketmouth"! What'ed that dude bite?
I really like the XL V(5) I have, about a 3/0 size reel. And definitely the UL XL plus. Now after all these years I know what the "XL" stands for. One thing I disliked was the ball bearing on the tail-plate; fixed in a seemingly weak graphite cup. I had problems with alignment and friction on the XL V, but the XL plus is probably small enough, and low stress enough not to have issues.
Soft jerk, lightly belly weighted. Killer wobble on the fall.
This is one smooth, easy casting reel. In fact, it may be the smoothest caster I own. I bought it years ago at a flea market for 6 bucks. Finally got around to spit polishing the important inside stuff. My word it casts. Carbontex washers too. This bass tested them a bit.
Some additions: My UMag II doing its thing as a heavy cover "frogging" reel. 19" and 21" (4 and 5lb) "pad crashers!". The exclamation mark is appropriate!
Great write-up! And fish pictures to boot! That's how you do it.
Yes, these are quite old and hard to find any more, especially even reasonably priced!
Used to be a lot of them around, before "the craze happened" and everything went sky high through the roof!!!
These are very sought after, across the pond, for tournament casting, super light leads, particularly the 18 gram!
They change the spools out on these, with ones that are all ported-out, to the max!
Many cool videos on YouTube, of these reels, on 13 foot tournament rods lol!
My oldest brother, had piles of these things when I was a kid, he was a freshwater tournament fisherman! So, these bring back very fond memories! But couldn't really learn the baitcasters, at 7/8 years old, and he was very short on patience, unfortunately!
He would tell me to shut up, and be lucky that I was using a spinning reel, or even fishing with him at all, cocky, sucker lol!
I see a fair number of them for sale. Not dirt cheap but not up there with the new reels nowadays. There are some bargains to be had it seems. I think most fishers would rather buy a new reel, much less fix up an old one as they all come in needing some TLC.
Maybe you find one, spiffy it up, and take your brother fishing! When he sees one all shined up he may get all warm and fuzzy toward it. Then you can tell him to shut up, he's lucky to be using a Chinese knock off reel and fishing with you at all! :d

Well, I like the way you think, anyway lol!
But unfortunately, his greed and arrogance, were way more important, than ever having a relationship with me, as we got older!
His loss, not mine, he was a terrible, role model anyway!
I'll just leave it at that!
Think I might start looking for some older Ryobi mag reels, I still have one, hanging around here that I've had forever!
Still performs flawlessly like new!
I acquired a lot of all brand new Ryobi baitcasting/spinning parts, a few years ago!
I haven't even gone through a Portion of them yet, the box wind up, getting wet in an old shed, and been afraid to even look!
Ach! Sorry to hear that. Yes, his loss. But yours too. :( Life isn't always right or fair. But we do the best we ca; If we can I suppose.
I've never owned a single Ryobi reel but always liked the looks of them. Probably won't bc... I have enough stuff to fish with, and then some. As to your box in that shed. Reels are meant to get wet. I'll bet they are salvageable. Just a bit more work perhaps?🤞

It is, what it is, my friend!
As to the box, "that was" in the shed, there were no reels in there , it's strictly packed to the gills, with nothing, but all, new old stock parts!
Well, I couldn't help myself, so I went out into my other shed at 3am, where I had left the box dry out, months ago, then placed it in an unsealed, contractor bag!
It seems, this was the second soaking, this poor box of parts received!
So, that's probably the reason, how, I wound up acquiring it!
I don't know what the hell is growing in there, but yuck it's a yellow-powdery, looking mildew or mold! It's growing on all the little tiny, brown paper bags, over the sealed bags, that were holding the parts! Some of the parts are perfectly fine, and some of them have slight oxidation/rust from being damp, unfortunately! Thankfully, most of the paper ID tags in the bags, are still readable! Seems, I have a new project for another day, they need to be rescue soon!
Ouch! I lived in sunshiny CO for a bunch of years and got used to arid conditions. Never had to worry about such things. I'm now in PA in a dark dank woods. I haven't felt humidity like this for a long time. Not to mention it seems to rain every other day.
