Need advice on 026 Repair

[lukem]

My FIL's trusty 026 turned not so trusty last week. The drum sprocket grenaded, took the clutch and oil pump with it. I guess he took it into the stealership and they quoted him $230 for parts and labor. I believe he is going to part ways with the saw.

The saw is a strong runner...I'm pretty confident the top end / carb / etc are all in good shape. I'm considering fixing it and keeping it for myself as a backup. Never done a repair like this before and wonder how much $ I could expect to spend in parts, any special tools required, etc.

New oil pump, new clutch, convert to rim sprocket, etc. Anything else I should consider?

$230 is a lot of beans for 15 minutes of labor. I'm guessing the parts cost is up there with the new oiler. I'd buy a new clutch and drum, scour ebay for an oil pump. Is that an 026 PRO or just an 026? Big difference in the pumps.

Assuming it is or can accept the 026/MS260 PRO style oil pump: (most $$)

That's $80 + shipping and literally 30 minutes of your time if you've never done an oil pump before and need to run to the store for more beer.

Remember the clutch assembly is a left-hand thread. (Righty loosey lefty tighty) You're gonna need a T27 Torx driver of some kind, A pair of pliers and a small flat-head screwdriver. 3/4" deep socket to run the clutch off the shaft. If you have an impact wrench, even better, then you won't need to stuff rope in the cylinder to stop the crank from turning.

Not a pro. Thanks for the insight.

Then what year is it? Post '97 (I think) can accept the PRO style oil pump with no mods. I think Boog Powell (member here) has converted a early style non-PRO to take the PRO pump.

EDIT: If there is a hole on the bottom of the case to allow a screwdriver to adjust the oil pump than you are good to go for a PRO style changeover. It will look similar to your 361 underneath.

Not sure of the exact year, but I'm 99% sure it is pre-97. It does not have an adjustable oiler.

The good news is the replacement oiler is about 15 bucks on ebay.

 

[lukem]

Cool. Sounds like it is worth fixing if this monkey can do it without needing any special tools.

Grenaded clutches are usually always due to running them with the brake set. Yes... people do it. It is very common on the 021-250 line of saws.

Boog sent me his old non-pro 026 oil pump but I cannot find it in my boxes of chainsaw parts. The only difference between the pro and non pro 026/260 models was the decomp button and the adj. oiler. The clutch drums are also different to run the oil pumps. Many of the non-pro 026s have the pro engine cases with the slot I the belly for the oil adjustment. I posted a photo of it on Boog's 026 upgrade thread on this forum. The clutches are all the same on the 024/026 and 260 saws. You can get a good used one and put in new springs for a lot less money (new clutch is an expensive part on any Stihl).

No special tools needed. Just a torx and socket wrench. And beer of course.

After further review, I found the 026 non-adj. oil pump that Boog sent me. I also found a good used 026 clutch (tight springs) that I have with a non-adj. pump gear, and a complete brake spring assy for it. I can send you the clutch, pump gear and brake assy for $25 (that includes shipping) and throw in the oil pump for free. That would get you everything you need to restore the saw except the clutch drum and rim drive set.

Wow.... stihhead... Solid thing to do. I have spoke with Boog about a half dozen times and he speaks highly of the info you have given him.

Lukem, well worth the shot, if he will sell at a discounted price, or give it to you?

ShihlHead that is very generous offer and I appreciate it. I haven't seen the saw yet and want to look at it first-hand before I take you up on that offer. I should be able to inspect it at the end of the week.

Good people on this site, that's for sure.

Hey Lukem, did you ever get a look at this saw and decide what to do? I've been away from the site for awhile ........................... picked up an old "1970ish" Ford 3400 backhoe (753 Auto-dig hoe) that I have been restoring .............................. I've been spending all my time on all the Ford/tractor/backhoe/construction equipment sites that I can find to figure some things out.

I did install an adjustable oiler in a non-pro 026 .................... didn't have the bottom hole either, drilled that too. Had to do some grinding on the case to get the deeper sprocket to fit but it runs great and doesn't run oil all over the place like my other 026 does. Have 18" bars on both of them, one .325 and the other 3/8. Love them both, second only to my pimped out 036!

Hi Boog. I've been so busy with yard work, gardening, kids' baseball, work, etc, etc, that I haven't had a chance to do much with it. If I took the time to work on a chainsaw that I don't really need I think my wife would literally give me the beating of a lifetime. Once things settle down a little I'll take a look at it, but that's probably not going to be until this summer. Still on the to-do list though. Thanks for checking in.
