Nose sprocket jamming.

[chilli]

would of said buy a husky but that would of been childish

 

This morning I checked the Husky (brand new bar & chain) as well...........nose sprocket solid!! Should have properly warmed the saws & got the oil flowing before use AND followed Hucks advice to dribble some extra oil on. Always used to do that but for whatever reason, I seem to have fallen out of the habit.

hi there.  I'm reviving a 15 year old thread to show I can use the search function but also because this is happening to me on a few stihl chainsaws.  The common factor is I'm using Rotatech Premium Bar oil and Stihl chains in all the saws.

 

- Stihl 088 with 25 and 36 inch Rollomatic ES bars .404 .063

- Stihl MS460 with 20 inch rollomatic bar 3/8

- Also to a certain extent in the MS261, but it has a short 16 inch bar

 

The 460 has had oiling problems in the past (solved by suggestions here) but I'm pretty sure these are fixed.  I replaced the pump, worm drive and cleaned out the lines and bar oil tank. Oil pump screws turned to max.  The saw gets through nearly as much as oil as fuel. It doesn't appear to have any leaks, but oiling is just poor. I can't get oil to flick off the end of the bar.  Unless the bar groove and oiling hole is kept scrupulously clean, the nose sprocket seems to jam up with dust and heat.  I can get it going again with WD40 and brute force in the workshop, but I worry about doing some damage. I don't do plunge cuts and this is not in extreme temperatures.

 

Has anyone had this happen with rotatech oil?  Should I thin the oil or try a thinner bar oil?  Any suggestions gratefully received.

Maybe try a different brand of oil, a 16" 261 shouldn't need max oil flow and I'd say personally thicker rather than thinner.

Thanks. I will and Im keen to see if others have this experience with Rotatech bar oil

 

Also I think older threads like this dont get the same profile - not on todays posts nor my notifications. Weird?

Last time I bought any rotatech must have been 10 years ago.

 

I use Gator as it's the cheapest on eBay especially when you're log processing, so a 25l might last a couple of months.
