3204 governor shaft seal replacement.

[1RJ01373]

Hi guys.
I've decided to try and re-equip my d4c with a decelerator, after taking off the lever I notice this small leak from the seal. Can I dig this seal out and replace it without taking anything apart?

Simple answer is Yes..
BUT you might find it difficult because it has a metal casing around the rubber seal..
Just be careful NOT TO gouge the gov housing OR the shaft..

I gotta ask: Is this a seep or a leak?

If it's simply a seep that just makes a dusty wet spot, I would be very hesitant of trying to fix it.

If it's leaking as an active drip when running and posing as a fire hazard, then yes I'd try to fix it.

But lots of gray area in between those situations...

It's a seep, like a little wet so it collects dust. Yeah enough said, I'm gonna leave it. Knowing me I'll do $500 damage fixing a $5 part.

I think that's the right choice...especially when @thepumpguysc answers your 'can it be fixed' question with a big 'yes BUT!'

I'm like you and would cause more damage than repair for most issues like this. Just monitor it and make a decision if it worsens to point of it being a safety issue.

And good luck on installing the decelerator. We'd enjoy seeing pics of how you're doing it and how it turns out.

I might try taking something really thin like maybe a piece of an old credit card and use it to clean between the shaft and the seal. Need to be really careful not to damage the seal. They make a tool called Seal Mate for cleaning fork seals on motorcycles. It cleans miniscule dirt in the seal to prevent oil weeping. You could make a miniature version.

The 3204 in my 931B is different and the governor cover comes off easily. On mine the seal can be pushed in a little and there's enough of a lip a second seal can be installed. Would have to look at a parts diagram but maybe your seal could be pushed in slightly and/or there's enough of a lip sticking out past the seal that it could grip a second seal.

Great idea,I should have thought of that. I've fixed many fork seals this way, just cut up a water bottle to make a curved plastic blade. This machine has been through so much there's probably already 3 seals pushed in there on top of one another,haha

It's amazing how many tips and tricks I learn from HEF members.
