And it was 49° this morning, but supposed to dip back towards the 20's again for the lows, brrrrr, I hate winter time.

I feel sorry for you poor SOB's that have to survive in those 49 deg temps..

I woke up to -21C and even more snow, about 20" in the last day or two.

Went it gets like that any exposed skin starts to hurt with in seconds. I do not mind cold weather but when it is like that with the wind is sucks.
Stay safe Mark out on those roads.

Thanks Roger, I'm going to do that.

I have not had time to mess with that aluminum wire in the welder. A friend lives by a race engine shop and dropped the case for the welder there to fix. He sent me the picture of the repair this morning.

Looks good enough to me, Now maybe can get some time to get this 81 back together..

The repair looks like it turned out great. Nice.

Took apart my 245a oiler cover. Is the cross type Lever on properly? I mean is the little nipple in the correct position? Seems like it's okay but want to be sure.

Yes that's right, nipple as you call it is against the brass gear

Whole thing operates. I assume the nipple makes contact with the brass gear and somehow depresses the plunger in the case.

 

[Modifiedmark]

I can't see that picture well on my phone, but you want that nipple on the ramp on the gear.

The lobe in the center of the gear gets rotation by the crank which walks the gear inside the cover and the ramp on the gear toggles the lever which accutate the the pump piston.

One of the more odd oiler setups but one of the best most reliable ones I have seen.

Hey Bob,
Did you ever find & fix the test pressure air leak on that 245? I read back through the posts & didn't see anything about it.

What kind of grease did you repack in the oil pump gear set, molybdenum? That stuff looks nasty...

Waiting to get the gaskets and reinstall the carb before doing another test. I used all purpose grease but maybe I should use a higher quality grease. Easier to do it now rather than later.

That inner crank seal on the PTO side can now be easily bubble tested while you have the oiler apart too. Like Mark said, the two cover bolt mounting holes into the case need to be plugged.

The oiler gears always have dirty grease in them after 20 plus years, the kind of grease that you wear in the cracks of your hand & fingernails for two weeks LOL. I don't know what the OEM spec grease was either.

Your S25 oiler parts are all done. I'll get them back to you next week. One diaphragm had the "big flat tit" type plunger, and I can't rebuild it, but the two others went fine. You'll have to get a new 5300 22124 dia, or maybe someone can donate an old worn out small plunger type "to the cause".

See how the center one in the photo has a much bigger diameter?, there's not enough height to get ahold of to compress the metal inwards to properly get the cupped washer off.

I've found three different types of those dia plungers, Poulan must have used different suppliers over the years.

In my prior tests there weren't any noticeable leaks in either seal. I can hear pressure escaping somewhere near the carb so I'm assuming it's the gaskets though no amount of spraying soapy water revealed any leaks. Thanks for fixing the S25 diaphragms.

Bob, check your Reed valve adapter to make sure the gasket mounting surfaces are flat.

I have seen them not flat and have straightened them out by using sandpaper on a flat surface.

Will do. Thanks. Getting both gaskets ( adaptor and reed valve) .

Ok men put your thinking caps on, working on my 361 i just got, rebuilt carb, it has the wick filter system. I know the tank is clean the filter is ok. The saw will start and run on idle only, if i try to go WOT it bogs and dies, no matter where the needle is, if you go slow with the throttle it will speed up about to the point it should run on hi side then bog and die, but it will idle all day long fine. Any thoughts?
