Is this closer?? Sprocket wheel D=25/Z=12 FORESTRYWEBSHOP.COM

Sorry. Didn't get that. On the plus side...it does look like a part used across multiple platforms. Good luck with your search.

First google search comes up with this. Looks very similaar...Item 14. https://avs.parts/deere/sprocket/f046098/

I'll keep an eye out for your review. I though the hyper was going to be less teeth to sharpen? Or that is what I got from Sauls vid. Made me want to get a skip for my Chilaskan 👍

Cheers @Rough Hewn The "shock" was something I suspected which is why I mentioned it. As said, I think the failures are mainly due to me expecting/asking too much from the setup. It's a good setup but not bob-proof. Yes .404, that was one of my plans. Small hiccup was that I already had the 661 and lo-Pro bars. I will in due course upgrade the bar to fit the panthermill then I'll be unstoppable :-)

Cheers @Rough Hewn and @Rob D I have (now) 2 x 42" 3/8 lo-pro's They both have replacement nose sprockets. First one (I believe) because no grease at all and a couple of hundred metres of milling ant it just failed. I lost all chain tension and the sprocket had disappeared. The plates had splayed game over. Second nose sprocket on new bar went after several hard months of milling mainly Oak and Beech. Have 2 rim drives and 2 saws that they rotate between. I try to keep things clean with a regular blast off the air line. I have also , unfortunately , made contact on both bars with metal. Enough to snap one chain and remove teeth on the other. Deep inside the wood and , I believe, out of the range of my metal detector. The bars have lost a bit of paint, but there is no apparent wear barring a small nick where the chain broke. I have tried to re-dress this to stop any further problems. The .404 have is on a 46" sugi /881 and is not a ripper chain but so far 80m of Cedar, Larch and Oak. No problems. Please don't get me wrong....I don't have issue with the Lo-Pro but think compared to a regular 3/8 or .325 and definitely the .404 the Lo-Pro is quite a lot more delicate. I do realise this and so try and treat them accordingly. I don't rush them or push hard. But do love the narrow kerf and the act on larger pieces it can give me an extra board. The reason for the thread was that my grease gun made all the right sounds but wasn't applying any grease. Same in my mind as having a sump full of oil but a failed oil pump.....it was only going to end one way! Thanks as always for all your great advice. I will take it all on and recheck what I'm doing as it will inevitably be user error on my part. Cheers Bob

Thank you. A very kind offer. I have splashed out on one of the metal ones in the hope that £14 trumps £4.99 Thanks Bob

Thank You. I have a generic one from Tree and Grass This looks the business. Cheers

Hi @Stubby I get you. I used to do the same with chains on my Motorbikes. Too much lube attracts , as you say. Thank goodness for o-rings. My experience with my GB nose sprockets is they seem to dry up and become a metal on metal very quickly without loads of grease. Then bang.

Thanks, to explain, I've had a couple of failures on my GB milling bars. Maybe getting a bit over sensitive but it seems to me putting grease in rather that relying on oil seemed to make them last. Cheers

Hi All, What am I doing wrong. The Greasing syringe ( for lack of a better description) keeps getting blocked. It gives similar resistance to me applying grease but it isn't reaching the nose sprocket. Has anyone got a better tool/device for doing this. Or am I expecting too much from a £4 thing?

Just re-watched it. I like the extra long dogs to stop the exhaust setting fire to the log ( I assume)

Hi Rob, @Rob D Didn't know where else to put this. Recently I have had cause to use your Whatsapp service and to use the regular email contact systems. On both occasions (you, I believe) responded extremely promptly and were extremely helpful. I was dissuaded form converting my GB 3/8 to.325 Thanks for this ... and was separately directed to correct Stihl Nose Sprocket, despite my local dealer not being able to even give me a hint at the right one. Thank you once again and I hope you continue to do well, as your customer service (to even the silly old farts like me) is absolutely TIPTOP! Cheers Bob

I hope you've had a smashing day and moved on a load of stock. 👍

I cheap out. Old petrol and 2 mix in a pot with an old paint brush to apply. Wipe down after a few mins with paper towel then a blow down with the air line. Generally clears everything.

Hi Saul, How do you dispense out of the 55's. Is there some pump or tap you use to fill a combi? Cheers Bob

apparently no. From Wiki.... The two giant sequoia drive-through trees have both fallen: Wawona Tree fell in 1969 in Mariposa Grove, Yosemite National Park Pioneer Cabin Tree fell in 2017 in Calaveras Big Trees State Park[

That's well priced. Is it all metal construction and good with Milling chains? Yes. Cast....something. The motor is quiet and housed in aluminium. Yes, I would say so. Have a look....here is the manual. Ultra Mk4.pdf Available on their web.

I had a cheap grinder it's ok on everything except the ripping chains for milling. I recently bought a Portek and the ability to set the angles correctly has transformed my sharpening. The Granberg still goes into the woods with me but the bench s master. Portek Ultra ChainMaster MK4 chain sharpener – FR Jones & Son WWW.FRJONESANDSON.CO.UK

Similar from last night.... we've had 3 nests in the stables...2 clutches from each. Reckon this'll be mst of them getting set to go home.

I was looking at adding roller wheels to my panther mill. I was going t use cheap skateboard wheels on an extra long M8( I think) slotted in the rail. Might need to bush out the bolt... to be seen as I've not done it yet.

Cheers

Cheers @Stubby Makes me feel a great deal more at ease. Did you have to re-tune your saws a some others have said? p.s. I've just read more on the Stihl site. Their Moto Mix uses Ultra HP so I might go that route when pushed.

Sorry to hijack: Looking at Aspen @Rough Hewn but like to use a fully synth 2 stroke oil. Do you (or anyone) use the 4 stroke mixes and add your own oil? Or are you happy that the oil they use is good enough? I know milling is hard on machines and want to be super sure before I change. Quite happy to go on the search for super unleaded until they phase that out.

Hi @harveyWhite I used a 25mm square 16 gauge box steel length. Seems to be ok. An offcut from my scrap pile.
