1979 Husky 44, how to get oil pump off...

[singinwoodwackr]

I assume this washer needs to come off first but it won't budge.
Suggestions?

I tried penitrating oil over night, no joy. Tried tapping around the circumference with a small punch and hammer…nope…

It's like the washer has become one with the crank
Need to get it off to replace the oil pickup.

Anybody? Need to get this thing off the bench, lol

From memory, it is just a cover washer and should not be a press fit on anything. Should be able to perhaps get an angled pick under the outer edge and pop it up?
Failing that- it should come up with the oil pump removed from the case- you already have the screws removed.

I’ve got a 140S which is somewhat similar, that washer can be a real pain in the ass to remove. Should be able to work it out with a small flat screwdriver. Gotta do a north south prying action back and forth until it comes loose.

Will try that…2 screwdrivers…
I was also thinking of trying a mitivac pump into the oil pickup line, minus the filter to see if that might push it out. After 45 yrs the o ring might need replacing as well.
the problem is that the oil filter had come off, probably years ago and was wedged in the case. Managed to get it free but now need to reattach.

Well, no joy. I even heated the washer with a mini torch...no joy.
I may tac-weld a couple bolts to the damn thing and use a puller.

Did you try the screwdrivers in different places, always keeping them opposite each other?

Yup, gave up
Welder to the rescue
A tack didn't cut it...had to burn a good weld to hold. That washer was really stuck to the shaft.

 

[singinwoodwackr]

Now, to get the stuck worm gear off
Got it!
Gee, think I should replace the seal?

 

[singinwoodwackr]

All that, for this...

What was holding the washer on so tight?

 

[singinwoodwackr]

I think I'll ream the little sucker out a few thousandths...

I think it had welded itself to the shaft...not enough clearance built in IMO

Now, to find an oil hose. They don’t seem to exist. Will try some from other saws…

Several on ebay from a search for "Husqvarna 44 oil hose"

My first attempt, too. It looks like the part number was super ceded, thus the more generic search.

I have an extra tube from a 61 carcass and it fits ok. May just leave that in.

Not sure if the washer had too tight a tolerance from the factory or 45yrs of age had something to do with it. I clearanced it by a couple thousandths and now it spins freely on the shaft but not too much to wobble.
getting the pump off again won’t be a problem.
