Title: tyrnos problems
Post by: alantani on November 20, 2017, 05:50:30 PM
got this email today!

As you can see in the video when I increase drag at one point the handle seems to be skipping the gear or comes disengaged from the main gear
everything looks good the gears look good the bearings look good what could it be
Taken apart 5 times!
I'm missing the handle thin gold washer. I wouldn't think that Warshire makes a big of a difference but it is not there everything else is in place as per assembly directions

Thanks for your help any input would be appreciated from the reel master!

yeeesh!!!!!  i've never seen one do that before.  the drag appears to be working, and at lower drag ranges, the gears appear smooth enough.  first thought is the handle slipping on the drive shaft or the drive shaft slipping on the gear.

there might be slippage between the handle (key #1326) and the drive shaft (#1346), or the drive shaft and the anti-reverse ratched (#1347), or between the pinion gear (#1352) and the pinion guard (#1356).  check those connections for damage. 

anyone else have any ideas?

I want the Blue Moon sweatshirt. No idea about Tyrnos. Good luck :)

Maybe the pinion bearing?... :-\

yeah, that's right, huh!  but it would have to be seriously messed up.  i'll ask him to check!

I've seen bearings with shredded inner cage, it's very much a possibility, but won't know until he opens it.

My first guess would be is the pinion gear properly seated in the drag pressure plate?  I have ran into this issue in my younger days when I used to install the pinion gear into the pinion bearing first...then I learned to install the pinion gear in the drag pressure plate and it went away.

I would have said pressure plate/pinion fit as well, but looking at the schematic it's a splined fit between them and hence very unlikely to slip, plus from the video it looks to slip 1/4 turn at a time, which to me suggests that it's a square part that is slipping.

When the slipping occurs there is no tick from the dogs, meaning the AR ratchet gear is not spinning; all bearings in this reel are after the drive gear (the main drive shaft runs on a bushing) which means it shouldn't be a bearing.

Also from the schematic, in these reels the AR ratchet is on the drive gear, not the pinion/drag plate; furthermore the drive gear isn't directly driven directly, rather the AR gear is driven and this is affixed to the drive gear by 2 screws.

There are only 2 interfaces in this part of the reel that use a square attachment; these are at each end of the drive shaft. I feel like the handle-end attachment would be fairly obvious if it was slipping; therefore my wager is that the driveshaft is slipping on the AR gear, due to one or both being reamed out. I would say both will require replacing at this point - even demonstrating the issue is likely doing more damage.

Hope that helps!

Main gear slipping on the main shaft.

The pinion gear sits in the bearing, when the lever is moved forward  the pressure is pushed towards that bearing and that's when the problem is noticed. I'm still thinking the pinion bearing is shot, but of course we won't know until he opens it. At this point, just a guess.

the spool shaft looks ok.

Reel master, I'm not saying you're wrong, I just want to mention that testing gears or bearings with a finger could give you different results from testing with 8-10 lbs. of lateral pressure.
If that was my reel, I would have replace that bearing to take the guess work out'  I would have then proceeded from there.

Just my opinion of course.

Take the pressure plate out of the spool assembly and insert the pinion gear. Hole the pressureplate in one hand and the pinion gear in the other and try to turn the pinion while it is fully seated in the pressure plate.

Next, is the pinion gear getting stick on the spool shaft?

Last is the main gear slipping on the crank shaft?  I haven't taken one of these a part in a while. I cannot remember if the main gear and shaft is one or two pieces.

Remember the crumbly, crappy drag these came with? Change that out to carbon fiber w/cals grease. Low drag pressure usually feels rough, like in the first video. Try putting some real pressure on a new drag and see what happens.

Bryan its 2 piece. It also has the 2 pins that key the main gear and anti reverse ratchet together. I still think the problem is in that area. My second thought is the pinion gear slipping in the drag plate.

I assume he made sure the handle arm isn't slipping on the main shaft.

That what i would recommend too.

After short time the original drag washer looks like an old carpet.....

For to get higher drag you can add an additional belleville. Based on TYR-30II can recomm configuration (((()
You have to remove one or two of the Thrust Washers! Figure out best for your reel. Do not know about which size we are talking.

Good Luck

Just a stab here. Maybe try to tighten TGT1186 DRIVE SHAFT SCREW. I just serviced one of these reels and had read somewhere that this nut will come loose and the handle may fall off or slip. I checked mine and got a 1/4 turn on it. If it was loose could it slip from the gear there?

I think Bryan and Keith have pinpointed the trouble spot for you.

Either the pinion guard teeth may be worn OR too much or too sticky a grease is causing the pinion gear to the shaft and bearing.
Have you tried it with just a thin layer of grease or thinning your grease with some corrosionX.
Maybe?

Good luck

My best guess is it's missing a piece or something was put in backwards, etc. I'm going with spacing issue.

Second guess would be corrosion inside the spool.

I don't see how the pinon bearing would cause that. A dead pinon bearing can feel okay in your fingers but will sound like a coffee grinder when the drag is engaged. A bearing that is that totally dead will be bleeding rust and will barely turn.
