Did a vid last night on installing seals on a solo 665. Never worked on a solo before, so, definitely not an authority there, BUT, this saw is for another member, and I was under the impression that these seals took an excessively large amount of time to get. :confused:

hmm

substitutions? been doing that a bunch lately.

Long story short, the PTO seal is the same dimensions as a husky 288/394/395 seal. 17 28 5mm

HOWEVER... the oem solo seal appears to be single lip :confused::confused::confused::confused::confused:

In addition, just looking at the spring its just itching to pop out, so you MUST use a husky seal sleeve (or coke can trick) to install. Personally, if it was my saw I would have put an am double lip in there (or oem 288 seal) ...single lip worries me.

ALSO, confusing things, the solo pto crankcase is NOT even all the around the outer lip of the seal. I put the seal flush with the height of the crankcase best I could.


Flywheel side is 15 24 7mm

just looking at it, there's no reason for the seal to be 7mm thick. 5mm would probably work fine. This was double lip so I was less worried. In a pinch it seems like these are reasonably available but I can't find exactly what other saw this might go on. 15mm means 6202 (or in the solo's case 6302) ... but a 24mm seal pocket width might be a tad odd. 268/272 is 26mm, so that won't do. other ideas??? the 24 od is definitely the trick here.

if anyone has anything they'd like to add go for it.

Am on top....double lip 288 seal.

Oem solo bottom....single lip.


Either way I'd prefer the double lip seal.

So you have the OEM seals and you want to put AM in instead?

I installed both oem seals last night. But the 288 seal appears like it can be substituted. If it was me i would prefer the double lip seal. Just sayin.

And no...I'm not taking out the oem unless there is a specific issue. Just observing what might be a possible better and more readily available substitute
