706z line roller won't come off rotor

[work2fish]

I'm working on an old 706z. When I opened the case it was full of old grease and a powdery dust. I'm not sure where the powder came from. Are there types of grease that dry up into powder?


That all cleaned up fine. However, I wanted to disassemble the line roller to clean and lubricate its parts, but after taking off the lock nut the rest of the assembly wouldn't come out of the rotor arm.




Does anyone have any tricks for getting the line roller assembly off the rotor arm without damaging anything?

Thanks,
Mark

ok, first of all, yuck!!!!  any chance that this reel is actually filled with fine powdery sand?  next, getting the screw out.  ok, this is likely not going to work, but here goes anyway.  install the nut back on the threads.  leave a gap between the nut and the painted surface.  now, heat the nut with the low flame of a propane torch.  don't let the flame hit the painted surface of the rotor because it will burn the paint.  heat will travel from the nut to the threads of the screw. 

get the nut as hot as possible without burning the paint.  yeah, good luck with this one.  don't burn the paint!!!! 

now, with the screw threads as hot as possible, add some oil.  i would use corrosion x or CRC freeze off.  now it's gonna smoke. then it's gonna cool.  and with any luck, as the threads cool, some of the oil will get sucked down into the threads.  and now, maybe, just maybe, the threads will loosen and start to budge.  or maybe not.  the main point.  don't burn the paint. 

if it doesn't work the first time, maybe try again.  or maybe not......

  I am going out on a limb here , but that sure looks likes some ones surf reel .. 
Dried saltwater salt powder and a bailes  kit added .  I would keep hitting it with penetrant oil and a little heat .

After you do what Alan and Joe suggested support the arm well, including around the guide, put the nut on enough to protect the end & first couple of threads and lightly tap the nut. That might break the corrosion between the guide and arm loose.

and that!!!!!!

Dumb question,is a PUM supposed to roll?

[work2fish]

Thanks for the suggestions, everyone!

I will get some penetrating oil and try the combination of heat and penetrating oil, and if that isn't enough, I will try putting the nut partially on and tapping it.

The powder that was in the reel was the same consistency as wheat flour, so I don't think it was sand.

jgp12000, I'm not sure about other reels, but the line roller on a 706z is supposed to roll. This one rolls, I just want to remove it to take it apart, brush and lubricate to see if I can get it to roll more smoothly. If I can't get the roller off the rotor I will just leave it as is. I've heard that the rollers on the 706z are not very smooth and quiet, even if in good shape.

It's metal on metal. There's no bearing.

Previous owner probably used loctite.

[foakes]

Manufacturers call metal bushings bearings.

And they typically work better than a ball bearing in rough surf conditions, over time.

The situation here is a combination of dried salt, fine sand, and really poor maintenance (none).

This will cause the PUM screw to fuse to the aluminum rotor PUM mount.

The remedy is to (as previously stated by others) get the PUM assembly off without ruining the rotor head. 

Then clean up the 4 or 5 components of the PUM assembly to slick, smooth, and as new.  Then a drop or two of synthetic oil initially and after every fishing trip.

Of course, the reel needs the same treatment inside and out.

This reel will turn out excellent when done properly.  They are both tough and forgiving.

I have new components, if needed.  But it should work out as is.

There are also about 11 small components that wear over time in surf conditions —- that would benefit from replacement.

actually, if the roller turns, it might be best to leave it be.

In industry they are called plain bearings.  Same thing though.

I have also been favoring the term  "plain bearing" over "bushing", but realized that I wasn't exactly sure what the difference was.  I just looked up the actual definition.  Plain bearings are bearings in the form of a single piece of solid material. So far so good. But it turns out that a bushing is a type of plain bearing in the shape of a sleeve and used to protect and decrease the friction of a rotating shaft.  IOW, all bushings are plain bearings, but not all plain bearings are bushings.

Agree with Fred.  Plain bearings get a bad rap.  They are can be preferable to ball bearings in many situations. For example,  where you don't need to worry about a large amount of axial load, but do need to worry about exposure to corrosion, like on a line roller on a spinning reel bail.

Turn the nut upside down on the stud, sticking flat side up. Now you have something to tap on without ruining the threads. Only leave one thread showing under the nut. That's more than movement to loosen it. Just be careful not to tap it off center or the stud will break. Ask me how I know.

Another great suggestion. I will try this, along with the heat and penetrating oil, and if it doesn't work with fairly gentle taps... I will take Alan's advice:

Probably won't have time to work on this reel again until later in the week.

In the meantime, in my original post the images showed up twice, inline with the text and then again under the post. Is there a trick to showing just the inline images?

I wanna see a picture if you "burn the paint"!
