Stihl 024AV alignment problem, swollen mounts?

[Wictor]

Hi all!

I'm working on Stihl 024AV, which is about 20 years old according serial number. Saw has not been used a lot and it's new for me, so I don't know the history and how it has been. I'm wondering what is the reason for bad alignment between the tank housing and motor unit. There is three rubber mounts keeping them together and I think one of the bottom rubber mounts has swollen or somehow changed it's dimensions. I have looked images of other 024AV saws and they have quite even gaps between tank housing and motor unit.

Below you can see how uneven the gap between upper cover and carburetor cover is. I have verified that carb cover is properly placed.

Below is just side view of the saw, upper cover should be in place.

Below you can see how gap near front mount is way larger than rear mount area. And there is not too much clearance between tank housing and oil gap area.


I have checked the upper mount and it seems to be fine. The bottom rubber mounts are very soft and I even checked that they are in the groove, so they should be in proper place. They both had number 1121, so they at least have correct model number. Have you seen swollen mounts? Do you have any other ideas what could cause this?

Thanks,
Wictor

top handle could be bent?

Take off the chain catcher and pull the plug, then work the mount back into place.

It looks like your forward lower mount is pressed in too far or it's not the correct mount.

That what I though and that's why I checked that mount is in the groove.

You might maybe take it partially apart to verify the fit.
When HarleyT or JJ give advice there is a chance they just might maybe have a notion of what the problem is.
Or eliminate that notion and get on to finding your problem and getting your saw fixed.

Pull the plug under the chain catcher.

Should look more like this......

 

[HarleyT]

Someone got the bar pinched and did some yanking.....

Or it has Stihl scoliosis.....

Stihl AV mounts at the bottom die from bar oil saturation. What looks good on the surface is crumbling and taken a set.

Just replace them.

Don't come on this forum and disparage both JJ and Harley in one thread. They know what they are talking about, you don't!

The circled mount is out of place. The one opposite is probably popped out of position also, as already pointed out. If they turned to mush, you replace all of them. Dish soap as a installation aide where needed.

Here are some photos of the mounts. I don't know the dimensions of the good mounts, but I think their length should be about the same.





I think they are either swollen or wrong parts. They have 1121 on them, which is the series number for 024 and 026. According the IPL, there are two types of mounts for AV series. I will get new mounts anyway and let you know, when I get the parts.

If I remember correctly, one # was a bit stiffer than the other. Either way, just replace all of them with the same style (stiffness). Bring the old ones with you. When they deteriorated they got like mush. Really soft.
The 2 different part number never felt that different to me. But, it's German engineering. Who knows.
They might have just popped out when the saw was stuck or twisted in a cut.
Sometimes you don't even know That it happened.
Just remember there's 4 mounts on that saw

 

[HarleyT]

Yes, they should be the same height.

I never saw anything get longer with age, except earlobes...

Yes, according IPL, the other set is normal and other set is soft.

Thanks for everyone for help!

Here, I took the junker I had apart. They are the same height.
