STIHL Oiler Repair (Most Even Model #s)

[D'Animal]

This procedure is for the following Models.

This procedure is for checking out the oiler system and pump on the following saws.

024
026
MS260
028
034
036
MS360
038
042
044
MS440
046
MS460
048
064
066
MS660

 

[D'Animal]

Remove side cover, guide bar, and saw chain. Run the saw and see if oil is coming out the oil discharge hole above the bar studs.

If no oil is coming out, check the oil strainer/pickup in the oil tank. Make sure it is clear of sawsdust and debris.

The top picture is what you be looking at when you pull it out of the tank.

The middle picture is the orientation of how it lays in the tank. The Yello area is the inside of the oil tank. I am using my Cut-A-Way Saw to show it more clearly.

The bottom picture is the oil discharge hole above the guide bar studs.

 

[D'Animal]

If that is clear then go to step #2.

Remove the clip, washer and sprocket assembly.

If you have a model listed above other than the 028, 038, 042 and 048, skip to post #4.

The 028, 038, 042 and 048 use the following procedure.

Remove the metal guide plate that is next to the guide bar studs. Should be a regular slot head screw. Newer ones may have a T-27 screw head.

Remove the "E" clip, washer and sprocket rim (maybe).

You should see another larger clip holding down the second washer. The second washer can be seen in the top picture, it is the one closest to the plastic cover.

I highlighted the cover screws in yellow so you can see all five of them when removing the cover.

For the following models use this procedure to remove the sprocket drum.

024
026
MS260
034

MS360
044

Remove clip

Remove washer

Remove sprocket rim and or sprocket drum. Don't forget to disengage the chain brake.

Now go here and follow that procedure and them come back here.

Once the clutch is removed, here is what you will see.

Some models have washers under the clutch, some do not. If yours has a washer, put it back in when you reassemble it.

The washer slides off the crankshaft.

 

[D'Animal]

The oiler gear slips off the crankshaft. It is a designed weak link of the system.

The wire clip should be snug on the polymer gear. If it is loose or the gear has melted, your oiler will not work.

The tip of the wire on the gear engages into the sprocket drum. The tip wears over time and no longer contacts the sprocket drum.

The average weekend worrier will get years and years of service out of the oiler gear. A professional logger will get maybe two seasons out of an oiler gear. The oiler gear is inexpensive to replace.

 

[D'Animal]

The most common causes of premature oiler gear failure are:

1. Normal Wear

2. The Clutch Slipping causing it to overheat. This can be caused by;
cutting with a dull chain
improper sharpening of saw chain
too long of guide bar
too agressive of a saw chain
forcing the saw to cut instead of letting the saw do the cutting.

3. Debris in the oil
This causes the pump to lock up

4. Wrong weight of bar lube (Winter climates)
The oil gets so thick do to temperature that it cannot be pumped.

I didn't know / don't recall that there was some big difference between even and odd model numbers. What is it about?

Difference really does not apply now.

It will be easier to find the oiler gear assy. The part number is 1125 640 7110

The biggest difference is the inboard vs outboard clutch assy.

Difference really does not apply now.

Almost all current models have inboard mounted clutches. The 009L, MS 192, MS 192T, MS 200, MS 200T and the MS 201, MS 201T still have the outboard mounted clutches.

Thanks for the info, I did find a dealer close by and picked up the part. Replaced the part but still no oil. Not sure why it won't work everything looks fine

 

[D'Animal]

Did you check the line for a blockage?

[mndotbob]

Yep all clear not sure what else it could be?

 

[D'Animal]

The housing could be bad. When a piece of solid debri goes through the pump it can put a groove the housing.

Good info in this thread that I am sure will popular in future searches, possible sticky?
