Sherwood pump help

Without the proper assy tool it is VERY easy to break the carbon seal. It has a carbon ring sealing against a ceramic ring. Be very careful

Sad to say but the 1998 SN is put away for the season. Was 42 yesterday, 80 today and high of 40 tomorrow.
What a roller coaster. I could use some help with my RWP. I opened it up today to clean it up and repaint it, and have it ready for the new impeller in the spring. Bearings are noisy so I would like to replace them before the freeze up like my 84 2001 did on me 13 years ago.
Of course then I think it only cost me $150 bucks for a whole new pump. Not today
Anyway the first problem is the tag telling me the model of the pump is gone. Only the part left under the bolt is there. Can anyone tell me from the pictures what the model number of this pump is?



Second is while trying to disassemble the pump to get at the bearings and seals I have run into a roadblock. It looks like there is a metal cup that needs to come out but I do not know how it comes out. Also the spring with the rubber bellows will not come out either. ????


An illustrated parts breakdown of the pump would really help me but have not been able to find anything being as I don't know the pump model. I know the rebuild kits are available but again what kit number without a model number.
Thanks for any input I can get here.
