Shimano Curado E Gear Question

Featured Replies

  • Super User

Please pardon my mechanical ignorance, but I have 2 Curado 51e's and would like to see about bumping the gears up on one to a higher ratio like 7.1:1.  

 

Questions:

Is this a possibility?

Is this costly?

What all part would this include?

Where would I find said parts?

 

Thanks for any help!

You can use the gearset from a Shimano Brenious. Aside from the main and pinion you need a few other parts. I have it all written down. Let me see if I can find it for you. Order the parts from Japan Tackle.

Yes, the core gears work great. I had a set in my Chronarch 51e. I mentioned the Brenious gears because you can get a little more ipt out of them. Core gears can be ordered from Shimano and I think it ran me about $30.

You need - Core 51 mg7 parts

Main gear - part 4070

Pinion gear - part 4073

Key washer - part 3941

Yoke 'optional' - part 4074

Thanks dudes!  I knew some of the gear junkies would come through for me!

Any links to some an article or video or something with the process laid out?

Take the handle and drag star off. Remove the side plate. Pull the pinion gear off and the main gear. Replace those two parts and add a little grease to the teeth of the main gear.

Core 7:0:1 takes up 28" of line.

Brenious 7:7:1 takes up 30" of line.

Core gears are aluminum and the Brenious has brass gears. I went with Core gears since they're easy to order direct from Shimano and the difference in ipt wasn't much.

The brens 7.7, core 7.1, its the IPT's that make it a slower than average

Yeah, that's why I just used the core gears. I was going off of memory but I was off a bit. It's been a while since I did the swap though.
