Updated in 2014 from the old site thread. Some stuff is lost but most of the part numbers are still good.

OK, several people have asked me what bars I run on my 361s and what rims, mods, and other stuff I have and that is available. This is not the thread to rave about or flame the 361 (there are enough of those already!), just the place to post mods and part numbers, what you run or like running on your 361, or have found to work better (or worse), and that kind of stuff.

Note: the 361 and 362 have the same oil pump part number, so the oil pump upgrade listed below will work on the 362 as well.

361 rim sprocket part numbers

These are the part numbers for the 361 rims from the Stihl IPL:

0000 042 1216 1 Rim sprocket 3/8" 8T
0000 042 1223 1 Rim sprocket 3/8" 7T <------ stock rim for the 361
0000 642 1239 1 Rim sprocket 0.325" 9T

Oregon has these rim sprockets that are a match as well (available at Bailey's and other saw shops):

Power Mate Rim, standard spline, 3/8-8, 8 tooth (Bailey's #ORL 22273)
Power Mate Rim, standard spline, 3/8-7, 7 tooth (Bailey's #ORL 68210)

Also Bailey's have some generic rim sprockets available for cheap:

Drive Sprocket Rim (Standard Spline) 375-8 Tooth (Bailey's #RSD 3758)
Drive Sprocket Rim (Standard Spline) 375-7 Tooth (Bailey's #RSD 3757)

.....

I run all 3/8" b&c on my 361s. I usually run an 8 pin rim with a 16 or 18 inch bar, and a 7 pin rim with a 20 or 25 inch bar, all with full comp RM chain. I also run an 8 pin rim with a 20 inch bar with full skip RMF chain.

*Stihl RM chain means Stihl Oilomatic Rapid Micro non-safety chain. For the 361, it is only available in 3/8" pitch chain, all gauges.

*Stihl RMF chain means Stihl Oilomatic Rapid Micro Full Skip non-safety chain. For the 361, it is only available in 3/8" 0.050 gauge.

Starter grip options

Starter grip handle options on the 361 with part numbers from the IPL:

1121 195 3400 1 Starter grip (1) USA
1128 190 3400 1 Starter grip ElastoStart

Corrected: The ElastoStart grip has a big stretchy rubber thingey in it for some give when starting, which can make it easier on your wrist.

Chain roller/dual dog kit

This is the Stihl part number for the dual dog and chain roller kit for the 361 from the IPL.

1135 650 7750

The cost of the kit is about $35.

Note that there is also a 3/4 wrap (Stihl calls it a full wrap) option kit for this with a different side cover. I will post that separately.

3/4 wrap, dual dog and deep side cover kit

The Stihl part number for this (according to Lakeside53 in some other AS threads is):

1135 007 1007

The kit includes a 3/4 wrap top handle (Stihl calls this a full wrap), a new deep dish side cover, a new (different) top buffer spring, a scrench, dual dogs and roller chain catcher. The cost for the kit is about $140. It will turn your 361 into a full R model saw that looks like this:

361 & 362 oil pump upgrade with 460R oil pump parts

Some people have had issues with low output from 361 oil pumps. I have not had any problems with oil pumps myself, except using a 361 with a 28 inch bar. After some use with the stock oil pump set to full, the 28 inch bar is blueing top and bottom near the sprocket tip mounts (Stihl ES bar) and the paint is burning off in these places as well.

You can replace the 361 oil pump with the full 460R (3/4 wrap) high capacity oil pump assembly. The Stihl part number is:

1128 640 3250 full oil pump assembly

You can also keep the 361 oil pump and just replace the piston and control bolt with the 460R parts. The Stihl part numbers for these are:

1128 647 0602 oil pump piston
1128 647 4803 oil pump control bolt

You can also replace the pump with the 460 oil pump or parts, and it will gush a bit less. If you are running a 28 inch bar, the plain 460 oil pump parts should be fine.

1128 640 3206 full oil pump assembly

or:

1128 647 0606 oil pump piston
1128 647 4806 oil pump control bolt

1/2 a tank or so of oil per tank of gas is normal on the 361. If your bar isn't burning the paint or other abnormal wear, it's not an issue. If you want more, as referenced above, put in the WRAP 460 oil pump parts.

BTW.. The 361 oiler puts out 91% of the Standard (not Wrap) 460 oiler. Why slightly less? because they use shorter bars. It's in another thread, but from memory (so check..) the 361 is about 15.5cc/min, the 460 17 and the 460 wrap up to 24.

I also run 3/8" exclusively, usually with an 8-pin rim with the 15" bar, and 7-pin with the 18".

15" and 8-pin make the saw an awsome limbing saw!

Stihl or Oregon rims make no difference, they actually look like they are made the same place.........

Great thread!

The muffler screen is part # 1135 145 8600 (and I need one)
The screw is part # 9099 021 0810 (and I need one)

Great thread! :clap: :clap:

My European version didn't come with one - so I don't have a spare one......


Just for the record, I believe the saws sold in NA and OZ are made at Virginea beach, while those offered elsewhere are made in Germany.

The only differences are the mufflers and cylinders.

Also for the record, the heated (W and VW/Arctic) versions have a metal handlebar, and weights .4 pound more.

Great post and thanks!

If I don't have part numbers in hand for these kind of parts my local dealer (rental store) looks at me like I am speaking a different language.

Lakeside53 muffler mod

Andy's muffler mod is a great addition to the MS 361. Lakerizing™ woke mine up, and gave it an angry roar.

Here's 9 pages of it: http://www.arboristsite.com/showthread.php?t=33528

Cliff's notes:
remove muffler
attach (weld or braze) small outlet tube
clean out any scrapnel from within, repaint, reinstall
install spark arrestor (optional but recommended as anti-suckback device)
readjust carb mixture

The part numbers for the factory spark arrestor and retaining clip are:
4223-141-9000 (fire screen, aprx $5)
4223-141-6600 (buckle, aprx $4)
and a piece of tubing (got mine at the local hardware, in the misc junk drawer, a "spacer/bushing" for less than a buck IIRC, enough to make two of these)

The OEM parts and the correct size tube that fits the screen can also be used on other small equipment... my FS 250 has one in place of the tiny OEM outlet.

Another option (once the muffler mod is done) is a Gen-U-Wine Stihl Magnum™ decal for the air filter cover. This sets your 361 apart from the crowd. Part # 0000-967-1593 and more $ than it should. Buy several, and Magnumize™ everything... pets, children, appliances etc.

1121 195 3400 1 Starter grip (1) USA
1128 190 3400 1 Starter grip ElastoStart

The ElastoStart grip has a spring in it for some give when starting, which can make it easier on your wrist.

Minor correction... The 1128 elastostart has a big stretchy rubber, not spring. The spring based version is lighter and not suitable on saws larger than the 200T.

First

the spur sprockets list for the 361 are 10, 11, 13 ! are the rim 7, 8, 9 a direct replacement in each or "MOST" cases?? now....

Noted the RM chain is listed for all the lower end model number saws?? Was the RM really meant for the lower end saws?? was it a HP thing?? I know it is a "semi" chipper chain "I think".. But then that does not make sence because it is listed in 404 gauge...

THis is just because a "A" stihl dealer was trying to tell me the RM is for lower end saws.. They also tried in a roundabout way say they where "all" low kickback!! Sometimes I think they are just trying to sell whats on the self!!

QUESTION NOW: 24/25" bar for "harder diry/mudy" wood - RM with what sprocket??
