Schaefer 2100 furler bearings

Many may already be aware of this, but for those who aren't I'll post the info anyway.
Our 310 furler has always been somewhat hard to turn, going in or out, since we bought the boat used. It's been getting worse, and since we just ordered new sails, I figured it was time to sort it out.
I've flushed it with fresh water often, but on these older drums it's hard to get water into the bearing area. Manufacturer recommends no lube, as it can attract gunk and grit.
I called Schaefer, the first person suggested rinsing it with a warm Simple Green solution. I wasn't a fan of this, since regular simple green is a bit corrosive to bare aluminum and needs to be thoroughly rinsed. But I have the non corrosive version for use on aircraft, so I tried that, removing the cage and drum end plates to try for better access.
Another several rounds of rinsing, and it was better, but still not right. Turning it by hand I could feel the roughness.
I went through the manual and the parts listing, trying to figure out how to replace the bearings in the drum.
I called Schaefer back, spoke to a different person and when I inquired about buying bearings, I found out they sell the drum assembly with new bearings for $250. As much as I enjoy fixing vs. replacing, thinking about the hours I'd spend trying to remove bearings from a likely corroded drum and installing new ones, I placed an order.
Watching this video from Schaefer, it looks relatively straightforward. And it shows that the new style drum has holes for flush water to get to the interior of the drum.
Waiting for it to arrive, hopefully before the new sails!

I received the new drum from Schaefer and finally found time to do the swap. Easier than I expected, I could do it in half the time now, but hopefully never have to. I should have done it sooner.
No need to drop the forestay, as shown in the video the drum disconnects from the torque tube fairly easily, then disconnect the bottom pin on the forestay after slacking the forestay and the backstay (as in the video use a halyard as a temporary forestay) and swap drums, then reconnect. The forestay is only disconnected for a few minutes.
As you can see in the picture, there are two flushing holes in the new drum. The bearings themselves are Torlon plastic, but the races are aluminum, and that is what corroded in mine causing the roughness. Being able to flush it properly will let this one last a long time.
It's Smooooth!
If you have the old style drum and it's at all hard to turn, it's well worth the relatively small cost and time to change it.
Now I'm still waiting for the new sails to play with!

Very nice. With the two side by side it is easy to decide which on you want on the forestay adjusting your sail.

Fair winds.

I replaced mine two years ago for the same reason. I would not recommend doing it while the boat is in the water as it is real easy to drop parts overboard. If you can't wait until the end of the season, have the boat hauled anyway. I had the Marina deliberately tilt the bow down on winter haulout so the weight was on the backstay. Was well worth the inconvenience of having to pump water out of the cockpit from time to time.

Had to replace the upper a couple years after the lower, lucky for me they had a "floor model" and gave me a little discount. We rarely haul out so more commonly done on the dock here, always good to have a friend help.

On the phone, the Schaefer rep told me it's a good idea to lower the sail and rinse the upper at least once a year. It doesn't get as much salt spray as the lower, so doesn't need rinsing as often.
Once they informed me that the bearing races are aluminum, I'll be much more conscious about rinsing. The new drum will make rinsing the lower downright easy.

Ok, you busted me, I left out the "drop parts overboard" part of the story.
