Pump maintenance?....
When you say "resealing"....what exactly are you talking about? From what your describing in your list of parts, it seems your talking about the seals to your pump.
I assume you do not have a manual or you'd know that you don't "reseal" it. You do an air test to see if the seals are leaking, if so, you replace them.
In your pump maintenance, what you'll want to do is, drop open the weedless grate assembly and crawl under the boat. Take a set of feeler gages with you and measure the impeller to wearing ring clearance. Stick the feeler gage in between the middle part of the blades edge and the wearing ring. Anything greater than .40" is bad. The wearing ring has to be replaced.
Yearly, you should inspect and replace the oil in your pump with a 75 weight, synthetic, polyolester oil. If you do not take the pump off, you need to drop the reverser bucket and nozzle. Once this is done, you'll see the cone to the pumps shaft and bearing. Have a glass cup if possible and take the three screws out from that cone, gently tap it off and catch the oil. The reason you catch the oil is for inspecting it for water aeration, which it will be slightly yellow in color. Also, lookin to see that there IS oil in it. If the seals are shot, you'll only get water from it. Now, lift the tongue of the boat as high as possible to drain out as much oil as you can.
With the cone off, you can grab the impeller shaft and try to move it from side to side and front to back. If there is any slop at all, the bearings should be replaced. Which means pump removal. If the impeller is beat up pretty bad, this will cause aeration, you need to get another one (you can get a remanufactured one for about $30 bucks).
If you suspect your carbon ring and carrier seal are bad, you'll need to pull the shaft to get them off for replacement.
The work your lookin to do yourself is do-able if you have any mechanical skills. But you'll really be lost without a manual to follow. You can pay up a month for use of our library and get all the info you need to do the job.:cheers:
