395xp seals update

[GoBigBlue1984]

I've finally had a little time to work on my 395xp rebuild and after installing the seals I noticed that they seem to have puckered out after being pressed on the crankshaft. It looks odd the way they are right now. Here are a couple of pictures. What do you guys think?

Looks like no one knows what these seals are supposed to look like.

I can't tell what the seal looks like from your pics.

Can't really see clearly, not that I'm the foremost expert. I did do seals in my 394 but from the pic, I wouldn't advise. Sorry.

If you zoom in on the pic you can see where the seal seemingly protrudes outward with the bearing surface of the crank. Which leads me to fear that the spring on the backside could have came off.

Though I must add that if it doesn't jump off the page to you brad (I know you've replaced seals dozens upon dozens of times) that perhaps it's not as unusual as it seemed to me.

I have yet to vac test, once that checks out- if that checks out- Onward I shall go.

I have seen this Saw first hand. The seal does infact protrude from both sides. Almost like it's supposed to be that way. Would using a press to install the seals cause them to pucker.

it is a pretty common thing to have the lip of the seal get caught on the step in the crankshaft. hard to tell from pics whats goin on...

They most definitely should not protrude. There's no sense in vac testing it. You need to pull and replace them. You'll likely have to use a film to slide the seal over the step in the crank.

I have used tape in the past. What is your preferred method brad. You have a lot more experience than me.

 

[blsnelling]

I use machinist shim material. It can still be a pain to get them in correct.

old micro fish works great got tons of them and any one want some, I have all the seal protecting tools for husqvarna and stihl

 

[idiotwithasaw]

I have had experience with having trouble getting them over the lip of the crank, but the worst is the clamshell stihl saws with the groove for the eclip that the oiler worm gear rides on. Impossible to work it slowly over it. I used electrical tape in the past but it's really too thick.

if i remember right the stihl clam shell have 2 different kinds of seal

 

[idiotwithasaw]

What is micro fish, is that a new type of sushi. Lol.

 

[idiotwithasaw]

All the 290 and 250's I have split had the same seal on both sides.

 

[backhoelover]

that is how the only manuals and ipl came to dealers back in the day google it

Yes...one set is for if you split the clam open..the other style you can install without splitting the clam.

I think I may have hijacked Brett's thread, sorry man.
