This is about my anchor windlass
, but actually this is problem for any engineer
I need to replace my sealed bearing on my Simpson Lawrence
Sprint Atlantic windlass
, but I have no idea how to get it on.
I took apart my windlass and found that my wiper seal was no longer sealing and there was a ton of rust underneath. So I ordered a maintenance
kit which included some spare parts
The problem is on the gipsy/gypsy drum. Look at the attached photo
. This is basically the drive shaft that runs from the motor
to spin the drum to pull up the anchor
- is the rusted remnant of what was left of the old sealed bearing around the shaft. It's really stuck on there, but I can chisel it off. That's not my real problem. I pointed it out to show the position.
- is a brand new sealed bearing. It would be just the right size to fit around the shaft, if it weren't for C below.
- is a metal strip that sticks out of the shaft. Sometimes it's called a "drive key". But whatever it is, it makes it impossible to me to put a new sealed bearing on from the right end. And the shaft is way too wide on the left end.
There is an edge around this drive key so it looks like it was added on later. But it's on really solid. It doesn't collapse, and it doesn't come off. Is it glued on? I don't know. But there's no way to get it off without doing serious damage. So how the heck do I get the sealed bearing on?
If you are curious you can also look at a full schematic by clicking on the picture here
. This shaft is part #95, and the sealed bearing is part #17.
Another option would be to buy a new gypsy
shaft. But I have no idea where. The company was bought out by Lewmar
and this model isn't made anymore. And I can't find this item available anywhere. Plus, even if I found another one, it would probably have this same problem with the drive key. And overall the windlass is shiny and it great shape except for the parts
I am replacing.
So what would be your next step?
