Question about Husqvarna , No.455 Rancher, 20" Gas - Powered Chainsaw

2 Answers

On my Husqvarna Rancher 455 the oiler was not pumping at all. This happened after I replaced the spur sprocket with a rim sprocket. I noticed the rim sprocket doesn't have the "dogs" to drive the oil pump. Changing back to the spur sprocket fixed the problem. Is there a rim sprocket that will work on this saw?

Replace sprocket on rancher 460


The factory do not offer a rim sprocket for the 455/460, they are classed as semi pro saws and as such get a spur sprocket, there may be an Oregon after market one available.

How to adjust automatic oiler on 455 husqvarna


I'm sorry, but I'm not aware of any adjustments that can be made to the oiler. Just make sure the ports are clean so that the oiler doesn't get clogged and that the oil lines are all clear and you should be good.

I have a rancher 455 and it's not suppling enough oil to the bar. Is there an adjustment for this?


The 455 has a 3 position adjustable oil pump, the adjuster screw is up under the crankcase, sprocket side, you need a flat blade screw driver.

Changing clutch drum on a husqvarna 455e rancher chainsaw


You have a couple of options. Oregon offers both rim and spur sprockets to fit your saw. Rim systems are initially more expensive but replacing just the rim portion is less expensive than 2 spur sprockets.
Oregon Bar & Chain Selector
http://www.oregonchain.com/pro/lookups/selguide.aspx?BusId=OCS&SellReg=USA&LangId=ENG

A part number for an OE spur sprocket and illustrations that may be helpful for disassembly may be found 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; black numbers on silver tag 90s; silver numbers on black tag 80s)
15 = week produced - March
00198 = 198th unit Husky produced that week

Your saw has an outboard clutch, this is a very guide for removal:
R² Drive Link Outboard Clutch by Drivelink.blogspot.com
http://www.youtube.com/watch?v=cdqkIuVNUQc
  1. 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).
  2. 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.
  3. Everyone I have ever removed had a left handed thread (tighten it to loosen it).
More questions or if I can be of more assistance please reply below. Good Luck. HTH

How do I get the clutch drum off? Husky 55 Rancher


A YouTube video shows the procedure using a Husqvarna 350 here:
http://www.youtube.com/watch?v=cdqkIuVNUQc
1. I looked at IPLs for the 55 & 455 and didn't see any special tools.
2. A length of starter cord or nylon rope may 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 be cut when the piston rises.
3. It is probably a left handed thread (tighten it to loosen it).
Let us know how it worked for you. GL

It appears the 455 must be a "spur" type chain drive sprocket. the 55 offers the option of a "rim and spline" drive sprocket. If replacing the clutch drum I recommend the "rim and spline".

455 rancher chainsaw does not pump oil to the chain


If you look under the machine by the chain you'll see a flat head screw (next to the sprocket) which controls the bar and chain oil flow . Try to turn the screw and check if there's any oil flow to the chain . If not you will need to replace the oil pump (part # 537 10 55-02 which will cost you about $35.00) Hope this help

455 rancher will not produce oil for the chain. Oil pump replacement? Need repair manual or parts breakdown. Thanks Warren


Also make sure that where the oil is pumped against the side of the bar that the oil port (little hole) that feeds oil into the bar's slot is clear. Mine would go through a tank of oil with each tank of gas, but the chain wasn't getting oiled until I cleaned out this little hole.
