Worn Crank Seal

[Steve Frazier]

I have a Deere commercial mower with a Yanmar diesel on the job that's leaking oil at the crank seal. Upon disassembling we discovered a nasty ring worn in the crank where the seal rubbed. I also noted when taking it apart that it appeared to have been apart before. The seal was about 1/16" from being seated completely and form a gasket material on the cover

Apparently this was a problem once before, as there are two rings worn in the crank. The dealer doesn't have a repair sleeve available. Anyone have any ideas?

Can you make a speedy sleeve on your own Steve? A piece of copper tubing... stainless or heck even plastic and then super glue it onto the crank...... to remove the sleeve stuck on with super glue you will have to add heat. Mic the crankshaft and head to the hardware store and see what you can turn up..... good luck.

Steve, the speedi-sleaves are the ones I use, I get them from the Mack dealer. If they don't have something that will work, most Parker products are excellent, though pricey. I don't know anything about the others.

Good Luck, and thanks for making a great forum. (though maybe I shouldn't thank you, since I am now an addict)

I've had grapple swivels where the seals carved some grooves into the spool. Had the surfaces flame sprayed and turned back to spec. $175.

Just about any local bearing distributor can order speedy sleeves.

Use some Loctite 680 retaining compound on the crank while installing speedy sleeve so it will fill the grooves in the crankshaft.

Try your local NAPA store they did handle C/R Speedi-sleeves.

Best professional advice ever.....especially the supergluing plastic pipe to the crank part...that was epic.

Sleeve it,seal it,forget it.

Thanks guys! I didn't realize these sleeves were so readily available. I stopped at a hot rod shop and he agreed to help me out, he'll come to the shop if necessary and measure the crank. I'll keep you posted.

Now that's what I call "service" Steve, sweet!

Laugh if you want, the name of the game is to see who ends up with the most marbles in the end. How you doing so far?

Marbles?

Ive still got most of mine....how 'bout you?

A speedy sleeve will probably cost less than 10 bucks for what he's talking about.

Farting around trying to find materials to bojang a piece of abs to the crank will take you at least an hour (if it works at all).....what's your time worth?

Man i love HEF! I have never heard of or even thought of a speedy sleave. But i know exactly where i need one. After the last repair, i thought i had to scrap my little $5000 irrigation pump, now i know how to fix it! WOO HOO!

 

[Willis Bushogin]

just fixed a $200 yoke on the back of a tranny, on one of my dump trucks. It had a bad groove in it, went to my local truck parts place and got the seal, speedi sleeve and it came with the installer tool, Loctite, $38.00

Steve, I apologize for trying to help you out with the crankshaft problem,,, I guess cutting edge doesn't value my opinions, so in the future I will keep my mouth shut so you can follow his advice . Sorry.

If the speedy sleeve don't work,glue some plastic pipe to it:falldownlaugh

The output shaft on the back of my service truck tranny leaks oil like a sieve (1.5-2 qts every week to week and a half). The tech from another branch that recently had it before me put a seal and speedy-sleeve on it. but as i have driven it the leak has gotten worse. guy at the International dealer said that if it is an Eaton (factory) seal that was put in it they won't take a speedy-sleeve and the extra OD to the shaft will burn up the lips on the seal and make it leak worse. Said I'd need to put in an aftermarket seal that will accept a sleeve. Ever heard of this?

lol...but honestly....the 2 wear marks on the crank are likey from the original seal : one from the seal lip iteslf and one from the dust wiper.

measure the distance from the crank nose to both of the wear marks and the depth of the seal in the front cover,so you can use these measurements to reference where the sleeve and new seal need to be located.

Cutting Edge.... grow up.

Ok, I think that's enough. Steve said in his original post that dealer didn't have sleeve available, granpa was just giving him options. Let it go.

Some seals, like some rear crankshaft seals, are specific about diameter, but most seals will accept repair sleeves.
