Thats a good SKF number, look it up on their website

You'll need to go there or to Chicago Rawhide anyway, to select the correct seal by dimensions!

Unless I have the IPL or OEM seal pulled out to actually measure the bore pocket & shaft, I wouldn't recommend buying a replacement aftermarket seal.

Ill check it out i worried about finding a seal that fits i dont think ive got a 9/16 crank i think its 5/8

 

[Boomer 87]

I found the 5522 and the 5523 they show to be exactly the same size. The o.d. of the seal i removed is correct with the 5523 the width isnt but that wouldnt matter. The only thing im unsure of is weather or not the id will work. I cannot find any seal anywhere with that o.d. but with a 5/8 i.d.

Did you ever locate an IPL for your P360?

The FW side seal SKF 5523 is correct for a P361, but I've never seen an IPL for a P360 to compare the two cranks. The 5523 is a nominal 9/16" (0.563") bore, and so is the NOS 530001986 OEM seal that I have in my hand.

If your P360 crank actually measures 0.620", or a nominal 5/8", then the SKF 5523 obviously won't work for you.

The 360 through 451 all use the same seals. I just remembered I got a Dayton version apart in a box, I'll double check it and get to the bottom of this by the end of the weekend.

Thatd be great bc im pretty confused lol.

Mark you sent me the IPL for one of these as well. I have my 360 and 450 apart in a box as well but not for long. I have the parts now to rebuild them

If you can measure the flywheel crank diameter of your 360. Im pretty sure mines somewhere around .620, which doesn't jive with everything else i found.

Well you're not looking very hard!, found it using my cell phone.

Chicago Rawhide SKF6120 is the interchange for a 7/8 x 5/8 seal, if that's what you really need, but be patient with the folks that have a 360 saw dissassembled, as I'm not tearing down a running 361 saw to check.

Hell i tried puttin the dimensions in skfs seal finder and couldn't find it, but im under the weather at the moment so my brains alittle cloudy

Can't do it that way, as they list the exact od & id, which are larger & smaller respectively versus nominal, and you would be chasing a seal for hours.

Go to their website & pull up the imperial or inch size catalog and look at nominal id, then od options

Then look at the material and construction types, you want a nitrile (or viton) and single lip with a garter spring type

I really am trying to help you...

I understand i do appreciate it i.haven changed many crank seals, but i have used many machinist tools i measured my crank again just now its .625 or 5/8 right on the nuts so ot looks like the seal you found is really the correct one.

Ok. Got my 245 back together enough to do a pressure test. Small leak near the reed adaptor but He I can fix that with a little 1184 sealant( by the way this stuff is pretty good. Never used it before). My problem, which I can't solve , is the leak around the muffler. All attempts to seal it have failed and this should be the easiest to seal. Question: If this is the only leak, will it affect the operation of the saw? My thinking is ,being on the exhaust side, it shouldn't hurt.

 

[Acornhill]

It should not effect the operation of saw at all.

Found another leak. At the
base of the case where the reed assembly fits in to. Picture attached. I scraped a little off and wonder what type of sealant would work. JBWELD or epoxy.

I thought you had new gaskets for all of these?

I did some more precise measuring and the 6120 is correct nominal 7/8 od, 5/8 shaft its 3/16 wide but theres ample room for width, hell of it is i gotta pay shipping so 5 dollar seal will 15 by the time i get it to me. Thanks for helping me out.

I do but there is nothing for this leak. Looks like this is a factory sealant as I've seen it on other saws. Just gotta find a sealant I can overlay. Maybe a marine sealant would work.

JB weld I would think

Hope this doesn't create more confusion, and it should make you feel better. I emailed an ebay seller of an OEM 01986 seal, and he was kind enough to measure the ID at 0.660", WTH? He probably didn't know to barely touch the inside seal edges when measuring.

All over the map with this one, I may go pull a starter cover & FW now, LOL.

The seal pair I have here came from Ebay a few years ago, and FW is tagged 530001986, but is only a 9/16" bore...that is where the SKF 5523 interchange number came from.

A 9/16" shaft is the same size as the smaller S25DA saws, so your larger 5/8" shaft measurement makes sense. So if that's the case, a 5/8" ID, then it's the same sized seal as a SKF 6119 used on the popular 3400 series 530019097.

The only difference between the two is that the later SKF 6119-530019097 is dual lipped.

I'll correct that seal application file & let MM know, as I think I caused the problem to begin with.
