Oiling problem - Komatsu / Zenoah

[cheshire cat]

Cheers CC, but I already have a duff one!

 

I managed to get hold of one today from the dealer that sold the saw. He had one in his drawer, it's a Briggs & Stratton number 285155121ZE and is also used on other saws by the looks of it. He had some parts website up which showed half a dozen companies offering the same part. They are available on ebay too. I don't know why the Komatsu parts list shows 285155120, maybe a supersession?

 

no a duff ryobi one to see if they matched----dohhh:001_smile:

Aye, chuck it in the post. It'll be useful to find out for other folk with the same trouble.

OK, I fitted the worm gear and also fitted a new bar & chain which were the recommended fitment on the Oregon website.

Now it oils the chain just fine but it also drips quite a lot of oil underneath, and also on to the clutch assembly.

When I compare the holes between the new and old bars, the new ones are twice the size. Is this the cause of the problem?

did the ryobi worm match and if so what was the price of the B&S one?

Dunno, haven't had it yet, although your message does clear up the mystery of the card I got through the post telling me they can't deliver a package because the sender didn't pay the full postage!

 

The bloke showed me the variation in price between the different manufacturers for the same part - between £9 and £18. He charged me a tenner so I can't grumble at that.

Think it was just turned up too far.

The Ryobi one doesn't match unfortunately. They are both the same dimensions except for the Ryobi is for a six-tooth sprocket and the Komatsu is seven. So theoretically if someone wanted to replace their worm on their Komatsu/Zenoah with the Ryobi item then they would also have to replace the clutch to match.

I've got exactly what you're after brassmonkey. A complete saw all up n running n oiling but no power (spares or repair). If you're interested let me know and I'll post it up in the classifieds next week.

that's interestin' I assume you mean chain sprocket the larger 44cc (rarer model) has a 7 tooth drive sprocket but the worm is the same p't no
