Penn 9 and Mag 10 aluminum spools

[Steelyfinn]

What is the difference between a Penn 9 aluminum spool (29L-9) and the Mag 10 aluminum spool (29L-10)?

I seem to remember putting a 29L-10 spool in a Penn 9 awhile back without a problem, but I see that Mystic still
Sells different spools for these two reels.  So now I'm wondering if that was a mistake.

Thanks for any info on this.

Does it work right? I know, real obvious question.

The 10 goes into a bearing vs bushing so likely the shaft is different, in the way 505 spools are different from 500 where the spool body is the same but axle made for BB HS model.

The 10 spool seemed to work and fit fine in the 9, but when I loaded it up with 15lb. Mono and tried casting it, I was having a hard time getting a decent cast.  Between the backlashes and line getting behind the spool, I figured it was due to operator failure and my old wooden thumb, so I just put back on the shelf and stick to my modern baitcasters with more cast controls.  Now I'm thinking that there could have been more play or spool movement during the cast because the spool axle ends could be a little smaller in diameter. 

Looks like it's time to take the spool out and put the calipers on it to compare it with the standard spool.

Thanks for the replies.  I hadn't thought of the bushing vs bearing fit.

I found this out ordering a 29L-501 on the bay, and when it arrived it didn't fit. The spool itself is marked as such, but I ended up narrowing a 505HS to use the spool. The seller did send correct spool and didn't ask for the 506 back, so I was plenty happy.

I have several dozen 9's and 10's, and the 9 isn't the best caster to begin with. I recco polish every metal-to-metal contact and use light oil vs. grease anywhere on this reel, and make sure you have the level wind tuned loose enough in the bushings and also that the slotted crossbar is rotated to the proper orientation so as not to bind the level wind. I don't know you so forgive me if I'm stating things you tried. I have many times trued up that crossbar, and then when tightening everything up to side plate, the bar rotates. Greasing screw holes helps a little to reduce that torque, but I always check when snug before final tighten. Also, if you were swapping in aluminum spool that tells me you possibly swapped out a plastic or chrome spool, which are pretty old by now, and that your bearings could need a look if so if same vintage.

Thorhammer,

Thanks for the advice and suggestions.  I bought several of these reels last year and went through them and got them running pretty smooth, and experienced what you're talking about.

This reel was the oldest and had a chromed spool, so I did want to replace it with an aluminum.  I bought one off the auction site and noticed it was marked as a 10 though it was advertised as a spool for a 9.  I assumed it was a replacement for the 9 as well when it seemed to fit and worked in the reel at the bench. When I looked at the schematics I realized they were still selling the 29L-9,
And that's what got me thinking about this.  One of the other 9's had an aluminum spool, so I'll spool it up and see if there's a difference in casting.

Thanks again for the comments- you can always count on someone here to have some answers.

Me too. I bought a spool listed as a 29L-9 but it was marked 109D-10 or something like that. Similar size spool, wrong length shaft. Also, FWIW because I always toss the levelwind frippery anyway, no drive gear for the levelwind idler, just the cog for the clicker. The right hand end was significantly too long. The seller made good with a refund and said keep the spool. Now I guess I need to find a reel that it fits. It's a very nice aluminum spool, only one mark on it, where I scratched it to see if it was really aluminum or some carbon fiber don'tknowwhatitis-ium. I know that with some reels, 109 was a part number used instead of 29 for spools, so maybe this fits something out there. I don't have a no.10 so its a mystery to me. Or it could have been made by an aftermarket supplier but it doesn't look Newell-ish.

109D goes to the 109- whole different aminal, and doesn't work. Tried that too

109 reel has levelwind. I have one. I removed the levelwind but it had one originally. This spool does not have the levelwind gear. It cannot be for a levelwind reel.

I am a big 9 fan since I mostly fish FW, so I am curious to find out as well.

Well, I had a little time between fall chores to break down a couple of 9 reels I have and a 10 that I bought that arrived yesterday.
I opened a newer version of 9 (black side plates with an aluminum spool) and the older 9 I put the aluminum spool in and found that both spools were the same and were marked 109D-10 with a 2 below.  All the dimensions were the same, and the same as the original chromed brass spool I replaced.
I then broke down the 10 and found it was also marked 109D-10 but with a 1 below.  The aluminum bodies of the spools of both were the same dimensions, but the axle of the 10 spool was offset to the right (crank) side about 1/8" and the axle end wasn't beveled as much. The axle ends of both spools were the same diameter.

So the spools are not interchangeable and do not have their part numbers on them anywhere. I think the numbers on them probably is a casting number with a version number below, since the aluminum portions of the spools are the same.  The drive end (right) of the axle seems to be the best way to identify the spools.

I'll add a couple of pics to show the differences.  The 29L-10 spool will be the bottom one on the pics.

I do have one modern 9 I assumed it was a plastic spool,never used it.I got fer $20 at BPS refurb section.

109 reel has levelwind. I have one. I removed the levelwind but it had one originally. This spool does not have the levelwind gear. It cannot be for a levelwind reel.

the level wind gear is driven by  the pinion gear in the 109  .unlike the 9, 10, 209 which have a drive gear on the non handle side of the spool
