It’s been about 6 weeks of on again off again scouring the internet for an oil cap for this vintage late 70s 61 case. I found the Husqvarna part number and determined that the cap also fit a 162. Armed with that information I kept looking, to no avail. Nobody is making these caps anymore, OEM or aftermarket. Such is the case when you’re dealing with 40+ year old saws. I did find a place in the UK that had a few in stock but they didn’t ship outside of the UK. It was then that I decided to just make one and add an o-ring for the seal. After some measuring I figured out it was an M24 X 3 thread, and the cap had to be vented because the oil tank lacked a vent. For this I just drilled a 1/32” hole through the center. It might weep a tiny bit of bar oil when laying sideways but I can live with that. Maybe some gauze attached to the inside of the cap will help? We’ll see. At least now I can tune it in the wood and actually use it.
I need a couple of those caps myself No hurry I'm buried in projects I'm going to order some of these to try THE DUKE'S OIL CAP FITS HUSQVARNA 61 266 OLD STYLE 501 62 66-02 If they're even close and too big I'd be happy I'll just try to dremel them to fit. I'm glad there's still some of us keeping the greatest Husqvarna series going Local shops won't touch them Or any vintage saws now The old techs are gone these kids will do carb swaps or fuel lines that's about it 120-140.00 labor per hour rates are common now People are just tossing old saws now.
I tried fitting an oil cap from a 1984 saw on this late 70s case. If you turn down the diameter of the cap to about 1.06” it’ll fit but the thread is still a couple MM too big. If you need a couple of the really old caps like I just made let know. Now that the design is done I can make more.
