Hi Halibut,
With the Andros (and many other lever drag reels) the 'binding' is felt as a resistance to the cranking of the handle. In freespool there is no resistance to rotation. As more drag is applied the handle becomes harder to turn. At full drag this resistance is very noticeable. The 'binding', or resistance, is caused by two bearings being operated outside of their design parameters. The left spool and right side plate bearings. When a side load (axial) is applied to a radial (normal) bearing it tries to push the inner race sideways. The result being exessive friction because it was not designed to do this. Thrust and angular contact bearings are designed for axial loading. The standard radial bearings will have a much shorter life because of this  Sad.

Thank you noyb72 and Tiddlerbasher.

 Once again, thanks! So if i got it right reading this schematics  -http://alantani.com/index.php?topic=1802.0-  the bearings marked "0910472"(pinion?)
and 0910475(left spool?) that causes the binding problem and should be exchanged with the above mentioned angular bearings?
Grateful in advance  Smiley

The bearings to change are part nos 0910472 and 0910447 (and NOT 0910475 - doesn't exist on my schematic  Huh?).

I see and understand, the schematics i refered to must be old. When i checked the one that followed the reel and not the one i found on internet, ther's no "0910475"
Anyways thanks again.

Sorry to bump an old thread, but has anyone had luck with purchasing the angular contact bearing? I'd love to do this, but having a tough time finding it.

I got mine from this company http://www.gmnbt.com/
Be warned you need deep pockets - they aint cheap Sad

There was a noticeable improvement on my Andros BUT I can get the same effect, with original bearings, just back-off the preset to 10lb at strike (20lb full). For it's intended use that is still pleanty of drag Wink

Any other sources for those bearings? I called the company today and it would be over $200 for a pair of those bearings! I love my little Andros but the handle binding issue makes me want to retire it, I already bought a Penn Fathom 2 speed to compensate lol.

As I originally said "you need deep pockets for the bearings".
IMHO it's not worth it - I did it as an engineering exercise, that's all Wink
On the original Andros 5 (with OEM Japanese bearings) set the drag to 10lb at strike - it will be about 20lbs at full more than enough for this line class of reel (50-60lb braid).
I've caught plenty of fish to nearly 200lb on this reel, most of the time never getting past strike!
Save your money and buy a new power knob Grin

Thank you for the reply. I was indeed shocked at the sticker price of those bearings! A new power knob or a gym membership!
