If it fills 'Tight' to crank it's damaging the the left spool and pinion bearings period!!!!
I've played with this reel (and bearings) for a number of years. Just set the drag to 10lbs at strike and you will get approx. 20lbs at full - the bearings will thank you

If you need more than that you need a BIGGER reel

Seriously - 20lb drag equates to 60/80lb line.
This was playing on my mind this morning, so I went back and took another look.
The resistance I am feeling is present at freespool. I think it is just the difference between a fully greased set of gears, and gears that were clearly in need of some love and attention!
To give a comparison, before I stripped it down, at freespool - and up until the last 3-4 clicks before strike, there was no drag. There was also very little resistance in the cranking handle, in that I could hold the reel on its side and by tilting/rotating, the crank handle would go round.
Now, with the greasing, there is an a resistance to that. The reel now freespools for over a minute, but the handle has a resistance that feels smooth... A little like changing gear in rear wheel drive car to a front wheel drive! It actually feels exactly like my Avet MXJ Raptor did for the first few days on the kayak, before the gears shed the excess lube I guess.
The important thing - that resistance doesn’t change from freespool to full drag... I think. I mean, I’m judging somewhat subjectively. If it does in fact increase, it’s by a very small amount.
I need to get it out and get it into action to really find out. This is on the agenda!!
In regards to the bearings themselves, time will tell I guess, but at this point, I think my key bring-back to the group is this:
I don’t think angular contact bearings are necessary. To get a right pinion bearing and a far left zpool/pinion bearing that a re both angular contact, you will be paying north of $100USD, or you are looking at unshielded chrome Steve bearings that will corrode in saltwater in no time.
If you can find some half decent deep groove hybrids (which I did!), then the deeper groove gives you a higher axial load capacity, and the balls are stronger than steel balls anyhow, so you are getting wat you need.
Half decent hybrids cost me (for all 4 bearings) $55USD. These, with a correctly sized sleeve give the reel access to a full, consistent drag curve and a drag level that SAFELY is beyond what such a little reel should be subjected to.
If you have - or come across- a Metaloid 5Nii that has been somewhat neglected, this is a great little project to turn around a reel that, when complete, feels 90-95% as solid and smooth as that MXJ Raptor. The fact it looks a bit battered makes it my EMO reel - so I’m happy!
