Of grooved shafts leaky oil seals (pic)

A few years ago I replaced leaking real wheel seals on my Case. I recall the axle shafts had some grooves but I went ahead anyway and installed new seals. Still no leaks.

NOW I'm replacing a leaking seal on my 30 yr old Troybilt's tiller shaft. I'm about ready to button her up but laid awake last night worrying about the groove in this shaft.

How long do you think these new oil seals will last with a groove shown here, just to the left of the bearing? The seal will slide on and cover the shiny section of the shaft .

If I can get a few seasons, I'll be happy. But wonder if it's worth the extra cash for a new shaft. Thanks for looking.

Kestrel,

Are you familiar with Speedi-sleeves and have you checked to see if one is available to fit that shaft? (They're NOT real cheap, though!)

I also recommend a speedy sleeve. The shaft could be turned down on the OD and polished, then a different seal could be used with the same OD and a smaller ID. This would not affect the taper fit of the output, and might be an option if the Speedy sleeve can't be found of the correct size. JimN
 
Speedi-sleeve it. You have some pits in there as well. Sleeve it and get another 30 years out the tiller.
 
I agree a Speedi sleeve is a good fix. But, I wonder about a differnt seal. Anyone had luck switching the plain old single lip seal for the same OD/ID/thicknes in a double lip? I recall a leaky seal on the PTO of an 8N can be easily repaired with another seal part number with the same dimensions just has a lip on both sides so the one side rides on the good part of the shaft. Need a good parts man to help find it.
 
Check a local machine shop they may be able to build it up and regrind it for a small price. Most shops are pretty good at doing small jobs for little or nothing just to keep a customer happy knowing he will tell others.

That is what speedi-sleeves are for. They are a thin stainless steel(hard) sleeve that fits tight to the good part of the shaft and allows the worn part to be covered over with a nice smooth slightly oversize seal surface. I used one on the axle in my skid steer. Dave
 
Thanks guys for the Speey-Sleeve tip. I had no idea such a product existed.
My NAPA guy just quoted me $39.00 each and I need 2.

May drop in on the local machine shop on my way out to see who's less expensive.

Or just go for a new shaft if it's a close call. Either way, I appreciate all the input.

Darn tomatoes are going to be expensive this year...........

There is another option...if you have a lathe. Machine a small undercut, fill with Devcon or equal epoxy, remachine. I have done this many times.
 
having owned several troy bilts now would be a good time to replace the bearings as well as they look a little rough

I definitely agree with the speedi sleeve and I use tons of them I question the $39 price tag you may want to try a Motion Industries or Applied Industrial. I suggest going on SKF"s website which now owns C/R who was the orignal mfr of speedi sleeve you need to mic the shaft size and your good to go just get a part# based on size and you can get a quote right away I"m thinking the numbers are simple i.e; 1" would be 99100 or if 1-1/8" it would be 99118 etc. The problem you will encounter is the the installtion tool they send will not work for your app just throw it away and use piece of PVC pipe to drive it on. I"m thinking $19-20 tops
 
You can press an "O" ring into the seal and that will tighten the seal on the shaft. This oil isn't under pressure so it shouldn't take much to stop the leak. Ive done this on fluid motors and it works pretty well. Not much cost involved either.
