Stihl 025

Hi guys, just been donated this old 025, start's and runs fine, but there's a bit of an issue with the oil leaking around clutch area, is it worth bothering trying to fix?

 

Thanks in advance

Keenly following this, as I have a thirty year old 023 which knocks lumps out of the 251 which replaced it. It has the same leak, and I'm idly wondering about trying my hand at a fix.

I did see a video, where a guy put epoxy resin over a new pump, but I don't know what/if the reason for the damage would mean it would fail again.

You will need to clean the whole area and see where the oil is leaking from. If you can pressurize the tank by pumping air through the pickup pipe it should show if the tank has a leak or it may just need a new pump.

A common fix these days with the likes of the 017/018/021/023/025 etc is to replace with a cheap chinese version of the pump, they tend to wear quick and leak from their bodies considerably more than a genuine one does once worn whilst working under pressure. Spuds theory is best, try a little pressure and check your area for leakage.

I guess Ratman is getting to that age if he is checking his area for leakage, best get those Tennas on

It appears that the o ring between the pump and plastic fitting is worn, mainly down to the casing damage, I'll get a cheap kit, bung up the hole with resin, for a fiver if it lasts a year all's good, thanks for the input.

Has the clutch got a washer behind it? If not it will just cut through the epoxy in seconds like it has the plastic where the pump fits.

If you look at the bottom of the pic, the brass colour is the worn away pump, below it is the black o ring on the oil connector, there is a small gap between the connector and pump. That's where its leaking from. As the main case is worn through a new pump and connector will not fix the leak.
