I need to get to the oil reservoir to repair oil tube in my Echo model CV 452 VL chainsaw (S.N. 0133209). I have removed drive shaft nut but cannot figure out how to remove the clutch mechanism. The parts manual shows a "clutch boss" but not how it is attached to the drive shaft. Is it a press fit or is the clutch boss threaded on the inside? If threaded, is it a right- or -left hand thread? Thanks for your help.
Hubert, I am hoping to see more answers relating to your question, as I am in exactly the same situation. I have the same saw with the same problem with the oiler. I will be stripping the clutch and sprocket side down tomorrow. If I have success I will add more then.
