Twist-Lock Caps???

[Clem]

Love my new Stihl 260, but what is up with this twist lock cap stuff? Bar lube oozes out all the time, this saw will need its own "storage sump." Will a new o-ring stop this or is this just part of the joy of the model?
Thanks, Clem.

Stuff is likely oozing out because you overefilled the tank, or didnt lock the cap in place. I love these caps, they negate the ability of employees overtightening the old caps and punching holes with a scrench. They are easy to use just don't overfill, and make sure the lock is engaged.

I also love them. A development that was long overdue. I also love the OUTSIDE bar adjustment One thing that puzzles me every time I fill er up tho is.

Why do they not raise the filler openings so that the gunk can be wiped away from around them before opening?? My MS310 is almost there but both caps have ridges in the way to prevent fully cleaning around them.

I don't care too much for them

I have just had my first bad experience with the typically over-engineered Germanic überKaps on a Stihl. Specifically the oil cap on one of my new-ish 200T's. Just spins freely and the cam won't engage, but pops over the cam continuously. Yes I am familiar with the scientific formula of righty-tighty. While it will finally engage if you play with it for five minutes and produce a thunderous rumble of expletives, that cap is going to be replaced. A minor PITA, but this is not exactly a cheap saw.

No problems so far on the new caps on any of the bigger saws.

Hey
Don't over fill the 260 or 200 and you won't have leakage!
If you turn the cap backwards till it clicks it will be O.K
OH buy the way I learned this the hard way, 30ft up and bar oil all over my chainsaw pants and my new Fly Line
ARGGG!!!!!!

I like the new caps also it makes it alot easier you not looking around for the scrench. I have the old style caps on my 046 and its not as nice as my MS260 with the twist lock caps.

It took me a bit to get used to the twist lock but now its a piece of cake now rarely have any problems.

I do think Stihl has tightened up on specs as I haven't seen as many problems recently as during the first year or so.

The recess does make for difficult cleaning but if the time is taken to clean prior to cracking the cap its not as much a problem. But then I don't have to clean them in the field just in the shop and compressed air makes it pretty simple.

A note for MS 200 users. If your cap does develope a leak replace it quick and if you are sloppy pouring oil in, learn to get it right. Spillage seems to be a particular problem on the 200's as the oil can easily get down to the coil which then attracts dirt and debris. I've seen a number of 200's with overheated igntion coil failures due to them being totally impacted with crud and not being able to be cooled by air flow over them.

I like the twist lock caps solely for the moron-proofing they provide. The design makes it hard for idiots to overtighten and wreck them (so far.) They could have redesigned the threaded caps with no groove on top so you can't stick a scrench in there. I figure finger tight on and maybe a scrench to loosen. One guy I work with was using large pliers on the outside of the cap after the groove wouldn't accomodate the scrench. I sent a saw down to another stickpicker and watched the strain on his face as he tightened the gas and oil caps. Why does it have to be so tight?

One greenhorn broke the coverplate bolts on a little echo because he thought that was how to tighten the chain. I assumed all the times that he stood at the back of the truck while I buggered with the saws that he was actually watching what I was doing.

I feel a rant coming on. I better take it to the approriate thread.

Got me a new MS310 and it's a learning experience with the twist lock caps, chain tightner and oiler adjuster. I have a parts cleaning brush in my saw box that I use for dusting off my saw before servicing.
