This is a Duel 6/0 two-speed. It's made in Italy and is rated to hold 800 yards of 50lb.
As far as I'm aware, the 6/0 generates nearly 20lbs of drag at the strike setting and nearly 33lbs at full.
I've heard of settings basically twice that, ie 32lbs at strike and more than 65lbs at full, with the addition of a few more drag springs, but have never tested this myself.
Certainly, the frame and engineering seem well able for this kind of capacity - it's beautifully made and built like the proverbial brick 'outhouse'.
Righto, let's kick it off...
First up, off with the gearbox assembly screws.
This won't release the gearbox as it's also fastened from the inside.
Unfasten the handle...
Remove the drag dial screw and the lever grip.
Off comes the dial, revealing the final right side plate screws.
The whole assembly will come away from the frame now.
There's a good amount of corrosion visible around the main shaft bearing.
The first drag plate is visible and floats on top of the remaining drag washers, which are held beneath a housing ring.
Remove the spool and put aside for now.
We'll remove the gearbox now.
The outer screw is just a 'sump plug', so doesn't necessarily need removing now, but if you're planning a full dismantle you might as well strip it all down.
On the inside of the plate is another hex head which releases the whole gearbox from the side plate.
Here you'll see the clutch level and drag feed.
From the inside, pop out the bearing and thrust bear (B).
Remove both screws from the inside of the gearbox assembly - they'll have Loctite on 'em, so be firm (yet cautious).
Remove the last gearbox screw and the gearbox housing will pop off.
I was very excited to see in here and wasn't disappointed - look at that!
You'll note that the housing is sealed with a rubber ring, so the housing acts as a wet sump containing a small reservoir of oil.
Slide each gear out separately, clean, regrease and replace.
In this instance, the whole assembly appeared basically new, so I didn't feel the need to split the two-speed gears, just cleaning, greasing and replacing.
Apply a bead of grease along the cavity in the edge of the gearbox housing and reinsert the rubber seal.
Refasten the housing to the reel-side plate and apply a little Loctite (or similar) to the two internal screws.
The third internal screw wasn't Loctited, so simpy reinsert and tighten well.
Once everything has been cleaned thoroughly and given a thin coat of marine grease, replace the delring ring and washer into the side plate, followed by the clutch lever and drag feed.
Slide the plastic washer (16/1) back down the shaft and bed-in as shown.
Replace the thrust bear (B) and refit the main right side bearing (which has had its shields removed, been cleaned with 556 and carb cleaner, and packed with high-quality marine grease).
Slide the gearbox assembly and main shaft through the right side plate and refasten first with the inside screw.
I couldn't find any information on exactly how much lubricant the reservoir holds, but simply matched with what was there - about 1/2 a teaspoon.
Replace the sump plug before it gets everywhere...
Put the whole side back together as follows.
You'll find, however, that the drag dial and lever grip will need to be removed again to refasten the right side plate to the frame - d'oh!
Replace the handle, grease and fasten down.
Now, on to the drag plates. Retrieve the spool and start on the right side.
Remove the housing ring and lift out the first eared carbon washer.
Remove the second stainless drag plate, followed by the second carbon plate (hence the 'Duel' name, I expect).
Remove the base drag plate to reveal the spring assembly and right side spool bearing.
Flip the spool over the remove the click disc, bearing spacer and left side spool bearing.
Clean, grease and reassemble as shown.
I greased both spool bearings as a reel of this size is highly unlikely to be cast - livies and trolling only I'd say.
Don't forget to replace the the bearing spacer (which slips into the left side bearing).
Clean the springs and spool, apply a coat of grease and start back on the drag.
Grease each plate well with Cal's.
This is where you can upgrade the drag by doubling the number of drag springs (from 12 to 24) to produce those higher drag pressures mentioned earlier.
Replace the first carbon plate, well greased, followed by the second metal plate and second carbon plate.
Replace the drag housing ring and put aside for now.
Back to the frame - remove the lugs and plastic ring.
Flip over and remove the left-side plate, lugs and plastic ring.
Remove the stand screws and stand. Clean all parts thoroughly (ie lugs, plastic rings and stand) and grease.
Remove the preset drag knob and disassemble.
Clean, grease and reassemble.
Once again, the spool bearing should have the shields removed, be cleaned and repacked, then the shields can be reinserted.
Slide the bearing back into the box seat and slip it back into the left side plate.
Here's how the reel seat fits together and how the plastic ring aligns.
Replace the right side spool bearing and fasten down the remaing reel seat parts.
Fit the last stainless steel drag plate and slip the shaft back into the spool assembly - nearly there now!
Fasten down the right side plate screws.
Refit the drag dial and lever grip.
Fasten down the right side plate screws and give the whole unit a once over with a clean(ish) towel.
And that's that!
Hope that's of some interest.
It appears to be a supremely strong reel and I really like the gearbox system, producing 3.4:1 forwards and 1.4:1 when wound in reverse.
All the best, Justin
