266 - 1981-1990 in case anyone is interested - that's Rick Astley and Kylie territory!

Nowt wrong with kylie, but as for the other one, well?

Well i can remember the 166, we had two both pre production test saws prior to the 266, they both went to the Forestry Commission, both had the twin steel ring pistons, and both blew up at around 100 hours, the inlet skirts of the pistons broke away, right mess, Steve i did very many 480K machines, i knew them inside out come the end.

ok i'll try and look at tightening bolts but theres so much oil under the muffler getting a seal will be lucky, any torque settings or just f***k off tight.what needs to be took off to get to these bolts?

[spudulike]

Probably the clutch drum and nothing much else. There will typically be 5-6 of them, two at the front of the saw and four around the crank area. They should all be pretty tight but they may have come loose and is relatively easy to find out. If you look around the area, you may be able to get a ball end allen key in to the screws to test them without removing too much but typically the drum and possibly the oil pump will need to come off!

Remember the left hand thread on the clutch - clockwise to remove!

[adw]

The pump will have to come off, 4 allen screws under here and 2 by the chain adjuster, if you remove the pump be aware the crank seal is retained in the pump housing, be very careful when re assembling as its easy to hook the seal spring out on the crankshaft shoulder.

Mmmm, just like that 380 I did....... use a bit of liquid gasket around that O ring - the seal will have probably gone hard as well! The joys of old machines!

ok so i gave the bolts a nip behind oil pump they were ok, the other two which i think hold the bumper spikes on? one was out because i took exhaust off when i put it back in the only bubbles were out of the oil vent so thats a relief. so original question is why do i get so much bar oil when running its soaking the clutch and dripping off the saw. everything is new orings xring pick up pipe.can the pump pump too much oil????

[adw]

Short answer is no, the oil flow is determined by the throw of the pump shaft, this is only altered by the adjuster screw, rotational speed is governed by the engine rpm, so unless the rpm is going into orbit.

[apvinny]

yeah i thought as much umm maybe it's something i will just have to live with. what about the adjuster screw mech do they fail?

[adw]

No not really, just turn the pump right down to number 1 position and that is it, if you fill both fuel and oil tank up and run it in the log pile, does it run out of fuel before it runs out of oil?
