The oiler gear that goes into pump can be removed. You "unscrew" it like you have done before. Once unscrewed, reach under the gear and grab the center shaft with a pair of needle nose pliers and pry/pop it off.
You can then access the screws and remove the oil pump.
You can disassemble the pump and check it for wear.
I'm back from my road trip.
I don't know your location so I cannot recommend a local place for you.
The oiler is super easy to replace. I doubt it is the pump. It is probably the oiler drive gear. Is the saw all tore apart?
Here is how to check it out yourself.
Take your bar and chain off.
Remove the metal plate that is around the bar studs. One screw in the middle between the studs holds it on.
Remove the clip on the end of the crankshaft. Once that is removed depending on the version of 028 you will have another washer and a large clip holding the washer onto the cranshaft. The 028 Super should have a rim sprocket but it will still ahve two clips and two metal washers.
Remove the large plastic cover that is about the size of you hand and kinda looks like the state of Michigan. Once that cover is removed you will see the oiler drive gear sitting on the sprocket drum. The oiler driven gear goes into the pump and just pulls off. The gears are plastic and are designed to wear. They are the weak link in the system.
This is about a 10 -12 minute repair, not counting cleaning time.
I doubt you need a pump unless you have been running used motor oil as bar and chain lube. I have probably replaced 500 oiler drive gears and two pumps in the last 20 years.
Let me know if you need any pictures and any other questions answered.

Old thread, new guy, loved the previous info, so, here I am!
Stihl 028 WB. My Dad bought it new in 1985, and gave it to me when he upgraded. I love this saw and it has treated me well. Unfortunately, the chain started to get hot, and I eventually wrecked the Oilomatic E bar. Also noticed oil leaking out of the bottom. I'm pretty tech savvy, but I have a newborn and other responsibilities and didn't want to tear into it because I didn't have the time. Brought it to a shop that wanted to charge me 300 dollars because the oil pump is leaking and starving the bar, and it needs to be replaced.
I said, "thank you, but I'll take it back in pieces."
I took a look at it, and the pump does push oil out, but I believe they ripped the seal out of the pump. I can buy a new pump from them for 90 bucks, but thought if I could get a new seal, and ask you great people some questions, maybe that would be better. Gears all look good, so please have a look at the following pictures and give me some input if you can. Thank you in advance!View attachment 1919658View attachment 1919659View attachment 1919660View attachment 1919661View attachment 1919662
