Oil System Plugged:

Remove the clutch cover, bar, and chain, clean the bar groove, any holes and passages on the rear of the bar (both sides, consider rotating the bar), if equipped with a sprocket nose ensure it rotates easily at least one complete revolution. Clean the saw oiler hole and channel. Insert a blunted, hooked piece of wire through the oil filler hole and pull the hose in the oil tank out. Pay attention to the screen or filter on the free end (clean or replace, difficult to determine serviceability). Start the saw and see if it oils when revved up (oozes down side of saw). If yes reassemble your saw. If no, continue with 2.
Work your way through the linkage (use IPL to identify components and locations) cleaning and replacing any defective parts as you go. Carefully check the hoses for cracks especially at bends and connections. If equipped with an oil pump it is usually behind the clutch (clutch is a left handed thread). Please make extensive notes & some digital pictures will help during reassembly.
If it does not oil on completion of 1 it is most likely a bad oiler or worm gear (see IPL). If your saw is a 455 an example IPL follows (may not be your saw): http://weborder.husqvarna.com/order_static/doc/usa/2005/I05000/I0501036.pdf
Provides component locations, part numbers and helps with disassemble/reassembly.
It has an outboard clutch use this and the IPL as a guide for removal: R² Drive Link Outboard Clutch by Drivelink.blogspot.com http://www.youtube.com/watch?v=cdqkIuVNUQc

Check the IPL for your saw to see if any special tools are needed. Poulan (Craftsman, Jonsered, Husky) clutch removal tool part number 530031112 if needed, is under $5 from many sources (look at the visible area between the weights if 2 small round sockets are visible you need the tool).
There are metal piston stops available, when square (almost never) with the piston top these work well, if not square they have been known to punch through the piston. I suggest a length of nylon rope (nothing left behind) be used instead of the piston stop (retain 6″ ± so you can remove it). Make sure the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and damage the piston as it rises.
Everyone I have ever removed had a left handed thread (tighten it to loosen it). Please download the correct IPL and if needed OM here: HusqvarnaUSA.com http://www.husqvarna.com/us/homeowner/support/download-manuals/ Enter the 3 digit model number (no XPs, Es, just the numbers) Serial number decode – useful when downloading IPLs and Manuals 06 1500198 06 = year produced – 2006 (single digit before 2000; please contact Husqvarna for single digit clarification http://www.husqvarna.com/us/homeowner/support/customer-support/) 15 = week produced – March 00198 = 198th unit Husky produced that week

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

The most common reasons why your automatic oiler isn`t working are: Your chainsaw`s oil tank is empty. The chainsaw oiler is clogged. The oil pump is broken.
Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power. While not ideal, these issues can be fixed by simply replacing the fuel in the tank with properly mixed fuel. But running a two-cycle engine with too little oil can actually destroy the unit.

Smart Start is one of Husqvarna`s unique technology because when their chainsaws are installed with it, it means it`s extremely easy to start.
Oil pumps are usually either inside the oil pan and driven by a camshaft or outside the pan and driven by a crankshaft. When those engine parts start moving, the pump starts working at the same time to pump oil to reduce friction and wear between moving parts and prevent the engine from seizing.
The oil pressure switch or sensor is generally located in the cylinder block near the oil filter or oil filter housing. Older vehicles usually have the OPS directly wired to the oil pressure gauge.
If too much oil is being applied to the chain and bar, it could pick up debris more easily, which could make the chainsaw cut less efficiently and also pose a safety risk as the debris is more likely to fly off the chainsaw at any time.
Two-stroke oil will last for a couple of years when it is not mixed with petroleum. Once mixed with petroleum we would not recommend keeping for more than 3-4 months in a sealed airtight approved storage container. I HAVEN`T USED MY CHAINSAW SINCE LAST SEASON AND IT WON`T START.

Where is the blade oil lines on a 455 rancher

I have a husqvarna 137 chainsaw. The problem is with the bar oil. When the saw runs oil is flowing but where the rubber corner piece which allows the oil to flow out of appears to be just dripping the oil straight out. It looks like it should fill a small reservoir behind the metal plate and the oil then moves upwards where the chains drags the oil through the oil hole on the bar which is moving outwards as in the top chain on the bar. However the chain-brake area is just getting messy with oil splattering all over and the bar not actually getting oiled. I have fitted a new metal plate to see if the corner of the original was not sealing properly but that has not helped. The bar holes are clean. Any suggestions as I can’t see what it could be?
ANSWER : It’s the rubbers. I had the same problem with my 137 and 141. The rubbers shrink over time and the oil never makes it up the channel. The replacement part is one piece and less prone to leaking than the original 2 piece design.

Where do i find the oil lines on a husqvarna 455 rancher

455 rancher not oiling – Husqvarna , No.455 Rancher, 20" Gas – Powered Chainsaw
ANSWER : May be stoped up at chain.

Not getting oil to bar and chain – Husqvarna , No.455 Rancher, 20" Gas – Powered Chainsaw
ANSWER : Release the chain brake and remove the bar and chain. Clean the side of the engine where the bar fits to, then start the engine. If the pump, lines, and filter are good, there should be oil oozing out of the port. If not, one of the above components is defective. If ok, then clean the small holes in the drive end of the bar that run out from the large holes to the chain groove on each side. They commonly plug due to sawdust and dirt accumulation. Hope this helps!

My husky 455 rancher is not oiling the chain properly. I have tried to clean all the oil ports on the bar and saw but it still is hardly pumping any oil to the chain. What could be the problem? How does the oiling system work?
ANSWER : The problem is very likely to be a clogged but more likely faulty internal oil pump (especially if your chainsaw is old).Hope it helps.

Husqvarna rancher, leaks oil when saw is off. where rubber hose meets pump, seems to fit together well but still leaks out. drains full tank of oil. any fixes or better parts.
ANSWER : The hose is leaking. You will have to replace the hose. You do not have to disassemble the saw in half as many seem to think. Just some of the parts that are in the way. You can insert a wire and pull the hose out from the oil tank along with the filter. It goes in and you remove only the parts that are in the way where the hose comes out.

Bar oil leaks out when not in use – Husqvarna , No.455 Rancher, 20" Gas – Powered Chainsaw
ANSWER : There will always be an amount of bar oil leakage when the saw is not in use, this is due to leakage through the tank breather, and oil caught up in areas of the saw which drain when the saw is stood, if there is not enough saw dust to dry the oil up ( this can happen useing long bars, but only cutting small logs ), if the oil leakage is not excessive i would suggest this is normal. The oiling is a constent loss system, so is not sealed as well as a car sump for example.
