Shock shaft seal and O ring 125 Force

[pastorbud]

I'm looking for the seal and O ring that go in the top end cap on the lift cylinder on a 1988 Force 125. It's the cap that has the four holes in it that you take out with a pin wrench.

I've found the bigger rings that go on the ram piston and the outside of the top cap.

I'm still looking for the beveled seal that the shaft goes through and the small O ring below it.

I believe this is what you are looking for either #4 or #6.

No, I saw those, thanks. Inside item #3, in the center hole, There is a small O-ring and a beveled seal that are not in the diagram. The beveled seal goes on the top and keeps water from coming around the shaft, and the O ring goes at the bottom, for purposes I don't really understand. That beveled seal and that O-ring were in a kit I bought off eBay that replaces all the O-rings and seals in the trim cylinder and in the lift cylinder. But that kit is no longer available on eBay or anywhere else I can find.

Here's a similar kit off eBay for a mariner single cylinder lift. The yellow seal is the top beveled seal http://i.ebayimg.com/00/s/MTMzMlgxMDQ4/z/ZAQAAOxycSdR4sht/$T2eC16J,!)sE9swm()OWBR4shs6Nh!~~60_3.JPG

You need a factory service manual, for the part #
Check your private messages.
Have you checked I-boats, they sell some force parts now.
Somebody on here awhile back said take it to a hydraulic repair shop,see if they have the bevel seal, o ring.
Did you check amazon, sea-way marine 425-412-4006 ,

Hey I'm got a service manual, I forgot! I'm so used to looking stuff up on the computer. But here's what it says, " if O-ring is damaged, head must be replaced. "

Can you change the o-ring only, without buying the head?
Or do you need the beveled seal too?

 

[pastorbud]

That's kind of what I'm wondering.

 

[pastorbud]

Normally when you have two seals on a shaft like that, one is to keep the water out and the other is to keep the oil in. This power trim unit had water in the oil when I bought it, so I'm a little picky about the part that keeps the water out.

The outside diameter is three quarters of an inch.
The inside diameter is just under half inch inch.
It's an eighth of an inch thick on the outside, not including the bevel.

This one is from the kit I bought about a year ago. The seller must be buying these things someplace!

It's marked "D-O 500 USA"

 

[Jiggz]

Actually that is more of a beveled gasket rather than an o-ring. You might want to google beveled gasket and see if you can find a similar one. The markings indicate style D-O with a half inch diameter indicated by the .500.

Got it. I'm a man on a mission now! Heh. Some web sites call it a hydraulic shaft seal, too. Gonna try a couple of local places that service pumps and controls. Maybe even NAPA.

 

[pastorbud]

eBay merchant that sold me the first kit says he'll have that kit back in stock and re-listed soon.

 

[Jiggz]

Well that is great. But after googling for beveled gasket, I actually found some similar items. However, since I do not have the item in front of me I cannot tell which one is which. But it seems it is more like a beveled washer or gasket used on some types of faucets. But hey, if you can get the kit from the original ebay seller you can't go wrong with that one. Goodluck.

Here are some photos from dead above and directly from the side. O.D. = 0.75". I.D. = 0.45.

No luck at the pump and control place. They suggested a hardware store.

 

[pastorbud]

Could probably make that one work in a pinch.
