Last fall I had a primary oil leak that was fixed under warranty. Bike was in the shop a couple weeks.

Now less than 5000 miles later, there is a tranny oil leak.

Very obvious since I use that unique looking/smelling Redline ShockProof Heavy.

I get a couple drops after she sits warm for 10 minutes or so.

At least I can check the tranny fluid level easily


Any ideas on possible causes???


Riding season just started - ain't bringing it in until the leak gets real bad or the season is over.

I have heard of the old Harleys having constant oil leaks, but a 2005 with only 25,000 miles???
THANKS

tranny seals

at any rate, don't let oil get on the belt for long because it will degrade it.

 

Are you seeing the oil below the primary plug and/or jiffy stand? If so, I'm betting it is your shifter seal. About $350 (mostly labor) because they have to pull the primary off to fix it.

Beary

 

Like stated, might be the shifter shaft seal. I bet it's from the weight of all those extra mirrors

 

I bet it's shifter shaft seal too. I've seen it several times and almost every time, it's SP Heavy tranny fluid ~ mine included.

Fix it yourself for less than $50. Get a Cometic "double lip" seal. The stock MoCo seals for this suck.

 

Actually Dawg, this didn't happen until I upped my sound system to EIGHT (8) Hogtune speakers. I think the vibration from the music loosened something - not the mirrors

PEZ, can you comment please

Seriously though, I figure at say 2 drops a day, it'll be a month before I'm down even an ounce.

Actually measured it: 50 drops = 1 ounce.

Still at the top on the dipstick.

Thanks for the tips.

This is this is the correct way to repair the shifter shaft seal. The MoCo, to save a few pennies per bike, uses a single lip seal. That single lip seal has to seal the dirt out and the oil in. A tough job for a single lip seal in that dirty environment. Typically they last around 10k miles.

I too, had a shifter shaft seal leak, and replaced it with a Cometic "double lip" seal. James Gaskets also offers a double lip seal.

If under warranty, most H-D dealers will only replace it with the same POS the factory uses. Then you will be back again, only next time you pay for it because you're out of warranty. It's about an hour, maybe two at best to do the job. Take it to an indy and get it done right if the dealer won't use the aftermarket "double lip" seal.
