My trusty 40 yr old 028 has the same issue. Thanks.
Love those saws!
Thank you, this helps me with my oil leak problem.
Fantastic! Thanks for watching and for the feedback.
Superbe video, merci et bon courage ! (De Bretagne en France)
Thank you very much!
Danke für das gute Video. Hat mir sehr geholfen…👍
Thanks for watching!
Thanks, man. Saved me a repair charge. And Proline replacement oil pumps are only $22 as opposed to $100 for factory. I'd like to buy you a beer.
Glad it worked out! Thanks for watching!
Do you by chance have the link for the oil pump? Like where to buy it from?
UPDATE: i JUST SPOKE TO STIHL; there did not, is not, and never will exist a high output pump for the 028.they are all the same. Thanks again for the video.
Ok cool. Thanks for the clarification 👍
I have a 271 FARM BOSS, It leaks also. (bar oil). Thanks for the info on how to fix it.
Thanks for tuning in and welcome to the channel
Thanks for video , is there a way to check passage way from tank to pump before going back together
I demonstrate the passages at the 7minute mark. Unless you’re asking about the gasket blocking the hole. For that I would consider either thin oil or air and slowly rotating the pump
I just put an o-ring around the plastic plug and reinstalled the pump. No leaks.
Excellent!! Thanks for the feedback and for watching!
When I switched from the regular bar lube, to 20 weight motor oil, my leak stopped. I think the high viscosity of the 'modern' bar & chain lube builds up too much pressure, and causes the leakage. Yes, you might need a pump and gasket, but if that's not the problem switch to a lower viscosity oil and give it a try. It looks like you did fine with regular bar/chain lube, , , thanks for the video. You picked up a new subscriber.
Thank you for watching and the feedback!
I found a manual for this model, and it actually shows what oil to use depending on your ambient temperature. Doesn't say bar oil, it says 20wt,30wt, or 40wt.
Good to know. Thanks!
@@allennewman632 Thank you.
great video, thanks. I would get rid of that spur drive, and switch it over to a rim drive, easier to replace in the future, and better diversity for drive ratio (7 or 8 tooth for variations of wood).
Yes that's a good call. Thanks
@@RayofallTrades you are welcome, thanks for the video.
Not sure if you can convert to rim drive because of that oil pump gear that is driven by the drum. Maybe there is a special hybrid drum that has a 325 pitch star for the gear then splines for the rim sprocket but I've never seen one.
@@glennmckinley3058i have it. Here in germany you can buy it.
11:00 minutes, there is an angle on the end of the worm gear shaft. That shaft pulses in and out of the pump end, as the flat spot reaches the supply hole, the shaft pulls away from the hole (sucking action), as the flat spot rotates to the discharge hole, the piston pulses the other way, applying pressure on the oil, and forcing it up the hole to the chain, (look up piston pumps), the wobble is to make the piston move in and out. There should be a spring in there somewhere (I haven't taken one apart yet), that keeps the shaft tight against the wobble area, so as the shaft turns, it also pulses in and out (Left and right). I found a part number for a High output pump: *I can't verify this to be fact* 1118 640 3211. I wrongfully concluded that different part numbers were different years, but they also denote oil flow per minute at max RPM, or at least the potential. the high output models have a greater wobble, which increases the pumping action. The flat spot is probably larger too, (Or cupped), to transfer more oil with each pulse. I just learned about this, sorry I can't give more info). Thanks much for the great video. One more thing. I found that thinner oil, as opposed to bar oil, will stop a lot of leaks, the bar oil build too much pressure, the transfer tubes cant handle it..
Those are great tips! I appreciate your taking the time to explain that!
@@RayofallTrades Happy to share info, always
Hi do you have a part number for that drum/sprocket you bought? Thanks.
I just posted it in the description. Thanks for asking and watching!
Awesome. Except you didn’t video where any of the snap rings go. Pretty critical imo
Great point! I’ll keep that in mind
I have an o28 av super that my grandpa bought in 1979 I found it in the scrap iron pile took it home cleaned the carburetor put gas in it and it runs like a dream but it's not oiling the bar I took it apart and the oil pump looked like it has chocolate milk in it and the plastic piece on the end was basically not attached would that be why it's not oiling the bar and chain any advice would be greatly appreciated
Pretty good chance of it. Check if oiling without bar and chain too. Oilers are available on ebay
Need some help finding a Stihl 028 super wood boss Oiler. Please let me know where you found yours. Thank you
Would like to purchase an aftermarket oil pump.
The OEM Part number for my saw is 1118 640 3211
I put the part numbers in the description area. I just found them on ebay. Good luck and thanks for watching and commenting!
I have an oil pump issue with my stihl 028 ac super. I have ordered 2 pumps on line and both of them have not fit.the Stihl dealer doesn't carry as the saw is to old.WHERE CAN I ORDER THE CORRECT PART.
Did it look like the one in my video or was it a ring style?
What is holding the plastic cap into the rear of the new oil pump? Do you think whatever was missing was the cause of the leak? If I had to guess I would have said it was a rubber cup rather than an O-ring.
It looked like the plastic cap was glued in. Probably epoxy but resembled wood glue. I never found an o ring but I expected to
Ray of all Trades Thanks. My guess now is some kind of gasket sealant, since that’s what they use anyway for other things, like crankcase and base gasket joints. Dirko or one of the variants like Hondabond or Threebond 1186.
I'd use 1187 / threebond but wait for it to cure
There keepers for sure
Music not needed
Thank you for the tip. I'm still learning!
I found this video from a google search, and I had a similar problem, except my saw was leaking bar oil while in the case, and when the saw was filled with gas, it leaked just gas. Is that oil pump a place where the gas and bar oil would meet? Or do I have another problem on my hands like multiple gaskets? I’m trying my best to not take apart the entire thing since I don’t have an impact wrench
Try to clen it real good, fill it up and let it sit on cardboard. They leaks might become visible. Sometimes it's just the caps
@@RayofallTrades Thanks for the recommendation!
Ray, where did you order your parts from
Some from Amazon and some from ebay. I put the parts in the description field
Helo!! А як з деталями до них є у USA
Thanks for watching
@@RayofallTradesfix your gasket with some grease it hold it on place.
@@andik859 that's a good idea. Thanks
This is not a Eisenschwein
Seems heavy to me. 😀
