Curado 50E Gear Swap

Recommended Posts

The cases appear to have room, Shimano can confirm before ordering parts. You need main and pinion gears for the same side retrieve.

The 7.1:1 gear set from the Core will work properly as the reels are made on the same tooling. The cost of the gearset is right around $30 if purchased from Shimano.

Pertty Sure Bantam confirmed this in a recent posting, can't find it though.

If you want a gear set installed it can be done as part of a standard clean/lube service for no extra cost. The cost of the parts I just pass along. If you want to DIY, Jfrancho posted the part numbers.

I can't remember with the Shimano, but swapping other gearsets - last one I did was an Abu whiffle spool Ambassedeur - sometimes required swapping drag washers, and shimming the AR bearing tube.

John,

What did you swap metal washers for thicker/thinner? I presume this was due to a main gear that was not as deep as the original.

No, the diameters were different, and the stack was all different. In the case of the wiffle spool, I used slower (3.7:1?) gears from a lower line of reel. Everything was different. I think we might have gained a "clicking drag" where there was an audible click when drag was slipping, like a spinning reel. That's a cool Abu feature - wish others did it.

Now, If I'm not mistaken, washers for a 7:1 Shimano gear set are different than the 6:1 and 5:1. That would require obtaining more than just the gears. It's easy to check, just look at the steel keyed and dog eared washer part numbers. No match, you better get those too. You might as well upgrade to Carbontex drags while you're at it.

It is interesting tha the Core 50MG and Curado 50E have the same large drag washer - BNT2431. Is the speed then obtained from more teeth in the drive gear and pinion gears and not a larger diameter? If so, then the key washer should also be the same size.

yep

Well I took a look and one inner drag washer for Core is #3548 and the 50E is #3915.

The key washer Core is #3941 the 50E #3213

You misunderstood what I was talking about. Both large drag washers for the Core and Curado 50 are BNT2431. The point being that if both large washers have the same part number, the inside diameter of the drive gear has to be the same. I don't know if both key washers are the same with different part numbers, which is common with Shimano. By the way, Shimano is revising their part numbers so that if the same part fits more than one reel model, the part will now have the same number, no matter how many reels it is for. Thank goodness they are finally doing that. No more having three part numbers for the same pinion bearing (BNT2170=BNT3927=BNT2192).

This would take you from the stock 25" IPT on the 50E to 28" IPT (the IPT for a Core 50). The spools are same diameter/capacity between the two reels so the IPT from the Core should apply.
