Leaking crankshaft seal repair

[John]

I just bought a Speedy Sleeve from Timken that fits over both ends of the crankshaft and creates a new surface for the seal to ride on, covering the small groove that has worn into the sealinig area of the crank.
The crankshaft end seals are: National/Timken 32x48x8 for the left sidfe, 32x42x7 for the right, and the sleeve is P/N 99128. It comes with the installing tool also. That's a big plus.The sleeve is a little pricey at $28 each, but it is worth the money to be rid of those oil leaks.

speedy sleeves benefit from a thin layer of silicone smeared on the inside before installing. If there are any lenghtwise scratches, it seals them.

Speedy sleeves

Can anyone tell me where to get one, need it for the left side.

[John]

You can get one at most any bearing/seal supply store. Maybe even a good auto parts store can get them.

Needed to try and get them on a weekend...bearing guys are closed..here are the common autoparts store numbers... usually not in stock, but sometimes you get lucky.

I have the seal but I need the sleeve for the shaft cuz the shaft is grooved so even with the new seal it still leaks, I was told it is called a speedy sleeve

[trbig]

There are also bearings out there that have a double lip that rides against the crank shaft. This might also help.

Just a suggestion?

Don't you mean double lipped seal?

[trbig]

Ummm... Yeah, another case of needing to listen to what I mean, not what I say (or type.. lol) Thanks for the correction John.

Hi, from some thread searching, I got the Left seal all fixed up, but the right seal I have ended up having a different size, my seal is 32x45x8 (instead of 32x42x7)

Engine #3H3 008xxx

Also, on the Speei-sleeve, if you have no bearing supplier handy, the Napa number is NOS 99128

In a previous thread I threw out some part numbers that I would like to correct for the right side seal. Yeehaw

[trbig]

Yup, both sides are different sizes. The actual correct thickness is 6.8mm, but nobody is going to have that. (Except maybe OEM somewhere.. in which you'll have to split your cases to replace them). That being said, you probably don't WANT to have the exact size back. I think even a 7mm thickness is too close. After a while, the lip will cut a slight groove into the crank.. which is the reason for the sleeve that John posted. If you buy another seal that's a single lip that rides in the same groove.. it will leak. I think anything in the thickness from 5-9mm should not have a problem.. but I would personally avoid using a 7mm if possible. If using a sleeve also... this doesn't apply.

Just my opinion.

From the DAMHIKIJD Files

The sleeve must be installed backwards, meaning the flange of the sleeve should be positioned away from the engine, and patiently installed with light taps of the hammer. DAMHIKIJD
But the leak is gone!

Hey, John...

I had that problem with the left side seal leaking on mine, just before Talihina.

(It was nice to finally meet you, by the way!)

So, I ordered one from Yamaha, then discovered the lip when I went to install it, and the need to split the cases to install the OEM style seal properly.

My solution wasn't as fast, (or as easy) as yours, but worked great, nonetheless.

My OEM seal paid a visit to the 'ole bench grinder, I carefully ground down both the rubber edge as well as the metal edge until it looked like the aftermarket seal with no lip. Applied a light bead of Yamabond around the outside of the seal, lightly oiled the inner lip of the seal, tapped in place, and let setup for 3 days.

Presto... no leak.

Why didn't I think of just turning the dang thing around? I was too caught up in wanting it to go all the way back up in the case, I guess. Gee...

Wrong Right side seal

I ordered the following seal, but it is too small.

Kragan
National 223215
Right Side

I Micrometered the original seal and found that the correct seal should be

National 223230

The outer diameter is 45 on the 223230 and on the 223215 is smaller.

I just bought the 223240 seal for the left side. However, it doesn't look anything like the picture above. It's a stepped seal. It looks like only half the seal actually penetrates the case, and the other half sits outside the case. Is that correct? Anyone have a picture of the seal they used, BEFORE they used it, or a new one, waiting to be used? I just want to be sure what I got was the correct item. All this talk of "lipped" seals makes me nervous...

Also, do I understand the posts above correctly, that you DO NOT have to split the cases to replace the RIGHT hand seal?? If that is correct, do I need 223240, or 223215?
