Hi,
I found this site by accident while researching 066 clones. Mostly because I decided to bite the time bullet and repair my own chainsaws. Though a truck mechanic, I have found lawn mowers and chainsaws do not operate exactly as I thought they would ...
I was surprised to see the crankshaft bearings on my Husqvarna 288 were not sealed bearings (one froze up solid and one lost a few ball bearings). So my question is ...
How are the crankshaft bearings and rod bearings lubricated ? Is it just from the gasoline mix?
The other reason for asking is I decided to chance buying a Farmertec clone off of E-Bay already assembled by someone else in the hopes they would do a better job then I would. BUT, I noticed the Farmertec saws require 25:1. Is this because of inferior parts clearance, bearings, available mix oil in China, because the older saws they clone (example 070) required it when it was SAE30 oil, or what?
I was thinking to be on the safe side I would run 25:1 since I plan on using the Farmtec mostly for saw milling, BUT, since I own multiple Husqvarnas (385/288) and Stihl chainsaws and plan on getting a real MS-660/880, I really do not want to mess them up running 25:1 in them. I currently run 40:1 Stihl mix with Stablit (sp?) added.
So, is it a good idea to run the 25:1 they say to run in just the one saw or all of them? Or just stick to the 40:1 with all the saws?
On the Husqvarna they suggest heating the chainsaw halves to 200 degrees C to press in the bearings. I was able to knock one out, but, it looks like I have to press the other out. Should I heat up the case to press it out?
I read the thread about using Loctite 518 on bearings, would you use it on bearings and seals going into a heated case? I am not too sure about installing the seal into a case that is 200 degrees C.
