Stihl 026 oil pump

[splinter1000]

Greetings all.

I need to find a replacement Stihl 026 oil pump PN 11216470040 which has been long discontinued. In another thread, one member (Lakeside53) recommended replacing it with PN 1121 6403202. Would anyone know if my original worm (i.e., from the '400 pump) will work with the replacement '3202 pump? Thanks for any guidance.

Check the parts in the IPL.

Is this an adjustable pump?

Thanks for the reply!

I have the non-adjustable pump. What is shown in the IPL is the 11216403202 non-adjsutable pump ( plus assocaited worm (ref number 16)).

I have an earlier version pump PN 1121 6470400 which is not shown in the IPL and is very difficult to find (at least for me). That is why I think I need to replace it with the '3202 pump.

I have no PN for the worm for my pump PN 11216470400 so I have no idea whether my existing worm will work with a replacement '3202 pump.

Not sure if worm fits. Might be better with complete new pump.

They sell adj pump kits, if your case has the place for adjustment screw

6202 should be the right pump.

I believe the only difference between the old number for the “fixed” crank driven oil pumps was the old number was for a metal housed pump, the newer number is a plastic housing, the worm should interchange, but even if it doesn’t and you need to replace the pump you’ll have to buy a worm anyway if you can’t find an old pump. Just a thought. Most older 026’s don’t have the housing cutout for the adjustable if you wanted to “upgrade”, unless it was bought as a “pro” model. The newer models have the cutout for the adjustable pump. I recently just converted a late model 026 to the adjustable, but others will tell you it is a lot of work if the cutout isn’t in the case already, luckily mine was.

Thanks (EC) Greg.

I can find a replacement plastic "3202 pump but without the worm. That is why I need to make sure my old worm will work.

Unfortunately, my saw does not have the cutouts for an adjustable oiler. If it did, I would go the conversion route.

Keeping a 40 year old saw going is a hard thing to do.

It's been a good friend.

I think the worm is about ten dollars from Stihl. Maybe less on Amazon but not really worth it for a few dollars. My 026 is one of my go to saws and dare I say it, (gonna catch hell for this) I like as much as my 346XP NE. Hope ya get it sorted.

Also, You will also probably want to replace the rubber feed line from the pump to bar mount area if it hasn’t been replaced for a while. They tend to harden up and split when removing them.

 

[splinter1000]

thanks ...I wan't aware you could still get the '1600 worm.

Copy on the outlet hose.

 

[EastCoastGreg]

If for some reason you can’t get the worm, PM me and we can probably figure something out. I have the plastic pump and worm laying around and maybe get it shipped to ya. It would be international shipping though, don’t know the cost.

 

[EastCoastGreg]

Parts 20, 21 and 22 all show up as available. This particular site is European but any North American Stihl dealer should be able to get.

 

[splinter1000]

many thanks!

Hi, I have an older 026, which does have the adjustable oiler hole. Is it safe to assume 1121 007 1043 conversion kit will work with my saw? Also, are there any instruction manuals on how to perform the work? I am new to working on saws.

Go to beg for manuals thread and ask for an IPL and Shop manual.

You'll need to pull the clutch off so will need a piston stop and deep well socket to fit the clutch. Left hand /reverse threaded.

If you go changing the pump you'll also want the output hose kit. They are a PITA the first few times you replace the hose.

Get the kit not the pre-cut hose, there is enough hose in the kit for two saws, or if you screw up the hose on 1st attempt. I think the hose has a spring inside like the 036 to prevent kinking. Don't see it on the IPLs.

 

[EastCoastGreg]

To add some to the mad professor. You will need quite a few parts on top of the adjustable pump kit. At least with the aftermarket kit I used. A spacer washer against the crank seal, a bushing that goes between the worm and the crank and finally a large washer that Stihl calls a cover washer. The cover washer goes on a specific way. If you can’t get a shop manual on the other threads then do a YouTube search for adjustable pump replacement or upgrade for the 026 for disassembly and reassembly and you should be able to see how it’s done.
