Daiwa Tatula SV TW Pinion Gear Noise

[Fishingthe402]

Hi everyone, first post here. I have been searching for a definitive answer for hours and can't seem to find anything that helps. I apologize if this question has been asked before.

 

I have been servicing all mine and my dad's reels the past week. He has a couple year old SV TW and the pinion gear is making noise when it spins against the main gear. It was not making the noise prior to servicing it. Everything has been completely taken apart, greased, and oiled. It still feels smooth and works better than ever except for the buzzing sound when the gear spins. I have tried taking it out and putting it back in multiple times now and it's the same every time. Nothing appears to be broken or chipped. 

 

Why is it making the noise? Or does the pinion gear simply need to be replaced? Thanks in advance! Pictures can be provided if that will help diagnose the problem.

The pinion bearing found under the yoke plate comes greased from the factory. If you cleaned it out and oiled it with typical, light, spool bearing oil instead of grease, you will lose the smoothness it had before you serviced it which can feel like gear meshing. That bearing has shields held in place with circlips which are removeable. A little bit of a pain, but doable.

 

The main crank shaft bearings should also be greased, but heavy oil will also work. Personally, I avoid using it in the outer bearing that sits on top of the roller clutch as it can be expelled over time and run into the ARB over time. Both typically have removeable shields too.

^^^^^ this. What PhishLI wrote.

Make sure the pinion shaft is greased where it rotates on the plastic carrier.

Thanks guys but unfortunately that's all been done. Even the bearings that have clips have been taken out and oiled. The noise is definitely the teeth of the gears when they spin together but like I said nothing feels rough or like it's not how it should be. It's just a simple buzzing noise. It does seem to get louder the higher the brakes are set though. The brakes and spool and everything have been cleaned and oiled as well.

So the particular bearings I referenced were oiled instead of greased?

Perhaps, but like I said, other issues can mimic gear noise/meshing.

Is it possible that you broke them down as a group and mixed non-matched/worn-in pinions and main gears where the gear ratios were the same?

 

Otherwise, a picture with the handle-side side plate removed might show something off during reassembly.

Thats normal for that reel.  The gears aren't the quietest and the plastic side plate let's noise transmit easily.  You can try greasing the gears but that is only a temporary solution.  The new Tatula HD 150 SV uses hyperdrive gears and is based on the same platform as the 17 Tatula SV so you could swap those in if you have the right Tatula SV.  If it's the 2020 model your only option is to get new gears but the same thing will happen again and you'll just have to accept that it will never be a silent high end reel (it never was).

Well, I guess I was under the impression all bearings should be oiled and not greased? I'm definitely not an expert at this yet lol

Thanks. That's kind of what a majority of the information online says. I was just concerned because the noise is new and wasn't happening prior to opening it up. It is still a four year old reel and I would be surprised if it was absolutely perfect at this point.

Sometimes it is quite hard to pinpoint where the noise is coming from, so I'd first make sure the sound is not from the spool bearings by changing them out. Once that's done, I'd loose the drag and hold down the spool with my thumb, then check if the buzz sound still exists when reeling. If yes, it's not from the gears, but probably from the two bearings on the crank shaft. If no, then check the pinion bearing, change it if possible. Also make sure there aren't any dirt or debris between the frame and the spool rim.

 

After all that, if the sound still exists and the pitch gets higher when you reel faster, it is possibly from the gears. To me, that sound is fine; it just means the gear teeth are meshing together. Thicker grease on the gears may quiet it down a bit.

My best guess is that it was already noisy, because a years old Tat is like a 1 years old micro module shimano, it'll buz harder than a bee. If you have other Tats, swap gear sets to see if the buz can be transfered to another Tat. Getting a new pair of gears will most likely fix the issue.

It was probably doing it before but bringing it indoors into a quite environment for service has made the noise more noticeable.

Well, thank you for all the help and suggestions guys. I've done everything possible except ordering and installing new parts. We will throw some line on it and make sure it functions 100% properly. He can live with the noise and if something else seems like it's wrong, we'll go from there. Grateful to have joined the forum and for everyone's knowledge here.

Some get light oil and some get grease. Re-read my first reply to you for reference.

 

The bearings circled on the '17 Tatula SV TWS schematic shown below are better served by being greased as they all operate at low RPMs during use and are under radial load forces during the retrieve. Generally, the reel will feel smoother with these greased, but like @Bigbox99 wrote, lower priced Daiwa models with plastic handle-side sideplates don't feel as smooth as their metal side plate models no matter what. If Hyperdrive gearing becomes standard, perhaps they'll be close enough.

 

That said, I have 7 year old 8spd Fuego CTs that have seen nothing but heavy-duty fishing using straight braid and stout rods, and while not glass smooth, they're not annoyingly geary either. The key is servicing them when you feel things change a skosh, or if you've been beating on them in heavy cover.

What you’re describing is normal and not likely to indicate the need to replace parts.  Yes, there are fine tuning hacks to achieve and maintain a certain feel (up to point) but you’ll get yrs of use out of that reel doing what you’re doing.

Phish, I apologize, I read that first comment a couple days ago. You are EXACTLY why I joined this forum. People with way more knowledge and expertise than I have and want to help other anglers. Eventually I would love to be really good at working on reels as I find it very fun and interesting. 

 

Thanks everyone for all your help. I am almost positive everything is going to function the way it should and the noise will not affect anything. I just serviced his 5+ years old Fuego and it sounds about the same.

As long as you don't feel any bumps or grinding in the rotation, you're A-OK.  Mechanical noise is normal.
