Question APOLLO AV-1 DPV Rebuild, Looking for Help

[LEO1982]

I'm not sure I understand the conversation, but the rubber seal you show can be replaced with a new one with a spring, If the spring is not Stainless it will work, but longevity is limited.

As for the advice - I think it was. to reverse the original orientation of that shaft seal (with the spring) do not do that. I made that mistake a few times, unknowingly and it resulted in consistent leakage and flooding of the rear compartment - i.e, the prop assembly.

Put the seal in the correct orientation or you will be disappointed. I think it is designed to have the spring on the water side, but I forget know, I will just re-assemble in the configuration I find it in. Do not worry about the spring being different than the original spring in the seal.

As for the flowable caulk, that is needed when you have to pull the black wall that the battery sits on. Sooner or later you are going to have to open it up and fix things or dry it out, so it is good to have the right material on hand to reassemble properly.

I think I understand what you mean
If you open the motor compartment partition, you should use caulking agent when reinstalling it. I think it refers to the silicone sealant mentioned in the maintenance manual. You just mentioned the spring size. Doesn’t the spring size being different from the original affect the sealing performance? Will being shorter than the original increase the wear on the shaft?
Did you use other brands of oil seals when rebuilding? Is the effect different from the original? Can you share what brand of oil seals you use?

Wow cool info!

Can CHRISTO-LUBE® MCG 111 be used

Man that's a lot of grease wasted

You've got this manual, just put it together with what you have and go diving

My original AV-1 does not leak and the the other one, I've never pulled apart

Thank you very much for sharing. It would be really hard for me to rebuild the AV-1 without this drawing.
Are you serious? I thought this was a photo you took after disassembling it...

I have obtained most of the information and parts needed for the reconstruction. Today, I have reinforced the broken bracket. Some parts are still on the way to mail. I believe that I can rebuild and test it in the near future!

Good luck!

Regarding the installation of the oil seal, I studied it carefully today and it is indeed as you said.
As shown in the figure, if the oil seal is installed on the oil pump, the spring should face inward, that is, the spring is immersed in the oil (the second lip dust lip faces outward). The first rubber lip has an angle, so when the internal pressure of the oil pump increases, the rubber lip will be pushed toward the shaft, so that the lip and the shaft fit more closely. The situation is exactly the opposite when used on the propeller, because the seawater pressure comes from the outside, and the pressure inside the clutch compartment will not increase, so the spring side needs to face outward. If it is installed in reverse, the seawater pressure will increase (greater than the force of the spring and the lip) and push the rubber lip away from the shaft, causing leakage!

The bearings ordered today have arrived, happy! I wish you a happy day too

Nice repairs dude I have a seal with a rubber oring spring I'll take a photo
after I grab another steel spring seal and fill it with some really good stuff

Do you mean to use this glue to fill the grooves of the spring?
This is a good idea!
But will this make the spring unable to expand and contract, and then affect the shaft? For example, increase the friction on the shaft?
I have ordered 316 stainless steel springs, looking forward to it!

Bro, your Chinese is very standard haha!
Did you use O-rings instead of springs? That's an innovation!
Use elastic glue to completely fill the grooves! Like I said, great idea!
One question, why did you remove those fences?
