Handle nut for Shimano reel...

[Skeeloco]

Was fishing one day and handle came off my Curado MGL. Screwed with it for a bit and got it back on. A week or two later, fishing again and handle pops off again. This time lost star drag spring. Ordered a new spring, now I can't get the retainer nut to stay on. Must have stripped it somehow...even though it will screw on fine with the handle off I must have messed up a tiny bit of thread. Anyway, where can I get a new one besides shimano? Over $10 with shipping. Spanner size measures 10mm so that would equate to M6 nut...not finding anything else out there.

[QED]

Seems the nut was most likely already stripped at the time the handle popped off since the nut retainer normally prevents the nut from backing out.

Ya probably the case. Seems the draft shaft threading is messed up a little bit but not the part where the retainer nut screws onto. Any Amazon nuts I've searched for are not proper size. I guess I gotta drop $10 to Shimano for a silly nut.

Give Shimano a call, they hooked me up with a free side plate screw and no charge for shipping, their service dept is outstanding in my experience.

Is your problem the retainer or the handle nut itself? If you stripped the nut hopefully you didn’t damage the main shaft threads. If so, send it in and I’ll repair it as needed.

The handle nut. It will not stay tight on the shaft. Once it gets snug hand tightening, I use a wrench and it will just keep turning. I may have overtightened and stripped it last time I put it on. Question is, why did it pop off in the first place? Read that it shouldn't come loose without already having been removed and I never removed it.

I find chasing threads one of my favorite things to do in the shop, part science, part art, and lots of $ from DIY bicycle mechanics...

2nd reason I pick up KDW titanium handle nuts when I'm adding up a Hedgehog Studio order - you pretty much can't strip the threads. (yes, this one uses a bolt instead of a nut)

@Skeeloco

At some point, you tightened it and began shearing-off the threads in the nut. 

They sheared the rest of the way from normal service loads. 

Keep in mind that aluminum handle nuts that come on reels aren't the same alloy or manufacturing as aluminum gears - there are a lot of shortcuts they can take producing these nuts inexpensively. 

[garroyo130]

How old is the reel? You stated you hadn't taken it apart before it popped off the first time. That is def not something that should happen.

[Skeeloco]

@bulldog1935 I was looking at the hedgehog handle nuts, but I'm not sure that the M7 will fit. Measuring the nut with my calipers, I got 10mm spanner size.

 

@garroyo130 Just over a year old I believe. Thing is, I did purchase it from someone on FB and it was in like new condition. Guy said he just wasn't a fan of it.... Not sure if he would have had a reason to take the handle off on a new reel but I guess it's possible.

I used an M7 on my Caiman, offshore slow jigging niche. 

All hex handle nuts, whether M7 or M8, are 10-mm socket - all locking retainers fit the same.

@Delaware Valley Tacklealready asked if you lost just the handle nut or nut retainer (nut cap) and I kind off confused of your answer. These are two parts to hold the handle in place together. The picture show, the nut (1) and black plastic(2) (retainer screwed on to handle) to keep the nut in place. Without the nut cap or nut retainer(#2), no matter how tight the nut it will eventually come loose.

I'm so gonna be first on line to your estate sale...

Very easy to cross thread, very fine threads.I just replaced a driveshaft on a curado Mgl and a bantam xg because client crossed threaded  nuts on both of them. 

[Skeeloco]

 

Didn't lose either, I lost the star drag spring. Handle nut is what I believe is stripped. I still have the nut cap. 

 

@shackman Somebody told me I will probably need a new drive shaft as well. Sucks cuz I already ordered new handle nut but maybe I can call them tomorrow and have em add a shaft to my order. Tell me is changing the drive shaft difficult? There's easily close to 100 parts to this thing looking at the manual...hoping I don't have to completely take it apart to change shaft.

 

 

 

[JustJames]

Are you saying, when you lost that spring, the handle with nut and nut cap attached (to handle) popped out? 
I think professional would be a better choice for you. You might pay more or pay less but at least it’s get done the right way.

Unfortunately yes, you have to pretty much disassemble most of the reel. I wouldn’t recommend doing it yourself if you’ve never worked on reels and on that curado mgl the idle gear is completely different the way it attaches unlike the K series. You have two small plastic pieces and two small springs. It’s very tegious putting those in without them becoming a projectile and you’d never see them again. Yes, a new nut will not fix your problem. You’re going to have to have a new drive shaft.

It sounds to me the op doesn’t know the difference between a nut with internal threads and the shaft with external  threads. Nut cap is the nut. The retainer prevents the nut from turning because you don’t torque the nut tight, just snug it up ant the retainer prevents the nut from turning.

Save yourself and send the reel to DVT!

Welp thankfully it was just the nut, I bet I cross-threaded last time I tried getting it back on. Still not sure how it could've come off by itself though. New one is snug as a bug. I guess $10 isn't bad considering what it would cost to get the reel repaired ?

It usually takes me a couple of tries before I'm sure the threads are lined up right. Any resistance when you hand tighten means trouble. Glad you didn't strip the driveshaft threads. I did that once while servicing my friends' left hand reel. To quote Homer Simpson, "Doh!"

Yea I got it on there properly but I got a right handed nut instead of a left and the friggin handle came off again after reelin in a 23" walleye!! ? Obvious it unscrewed itself...Shimano sendin me the left handed nut.

Is it a left or right hand reel?

Then how did you thread it on in the first place? Sounds like you got the correct nut, but the driveshaft's threads are rolled enough so that the nut pulled off from torqueing the handle. The nut can't simply spin off by itself because it has a locking retainer. Also, the handle is keyed to the driveshaft, so it can't spin the nut off either. From here it sounds as if you need a new driveshaft and nut.

 

If you have a right handed reel, then you need parts for a 150. If you have a left handed reel, then you need parts for a 151.

Exactly right..once you cross thread the drive shaft threads, there is no do over, you’ve already rolled the threads.brass is soft metal. It might tighten up and you think you’re good but all it’s doing is tightening on the rolled threads and it will come loose again just like it did. Just like Phish said, new driveshaft and nut is the only thing that’s going to fix the problem.
