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

1 Answer

It's not pumping bar oil. I've checked the bar itself and cleaned everything out. There's no oil reaching the bar. I'm not too familiar with where the pump is and how its supposed to work. Is it mechanically driven by the engine or is it a separate device? And, how do I get to it? Thanks, Doug

Hello Doug.
It is a gear driven pump located behind the clutch. Find your IPL 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
The parts list is very helpful with disassembly.

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 certain 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. Most (99.9%) clutches have left hand threads (tighten it to loosen it). If a finger nail held in the thread and rotated clockwise comes off the shaft it is a left hand thread. If it pinches against the clutch it is a right hand thread.

If you have more questions or need additional help please reply below and I will get back to you. HTH & Good Luck.

I have a Stihl ms390 saw that is not oiling the bar but pumping oil out a 1/8" diameter port just below the muffler. Is this normal and just missing a plug. Does this condition sound familiar to you and...


The oil should be coming out of a port under the chain and bar cover. Remove that and the bar, there is a small hole there that the oil comes out of that should align with a hole in the bar. If it's coming out the front, something must be wrong. Make sure the one under the bar is clean, sometimes debris can plug it.

Bar oil will not go through were do i check for blockage


Remove the guide bar and clean out the delivery hole in it, flush the oil tank out with a suitable cleaning fluid and try again, if this does not work it may be an issue with the pump itself.

Husqvarna chain saw 385 xp chain or bar not getting oil at all


check bar oil holes,
check oil tank pickup filter - should be clear, clean oil tank

remove drum and clutch, check drum and check oil pump driver arms ( could have worn or broken off and drum is not driving it around ,

check the worm part of the pump driver as well ,
remove pump oil pickup lines and outlet lines , check that both lines are clear and that the pump is not all bound up / stiff or damaged if everything else is good

i would replace the pump and reassemble , tighten clutch anti-clockwise ( clockwise to loosen it ) make sure drum cut out engages oil pump driver arms

as a rule if replace pump also replace pump driver , they are matched

Not getting any oil on the chain and the oil is full


Remove the bar and chain--clean the cover and case side. Start the engine and see if oil oozes out of the side port where the bar fits. Also, try the manual oil pump if it exists. If ok, clean the bar end oil-passages including the two channels that run from the large holes out to the chain groove on each side of the bar. Clean the entire chain groove, and check the tip sprocket for free turning. If no oil came out of the port, then remove the rear case which exposes the two tanks, the oil pump and the bracket that holds the bar to the engine. The oil pump runs by use of crankshaft impulses and has a diaphragm in the pump body that may be damaged. Also check the tank filter fitting. When you get everything back together, run the bar tip at speed near some cardboard--it should throw off a thin line of oil after several moments of fast running. Hope this helps!

Oil System Plugged.
  1. 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) Clean the saw’s oiler hole and channel. Start the saw and see if it oils when revved up. If yes reassemble your saw. If no, continue with 2.
  2. Insert a blunted, hooked piece of wire through the oil filler hole and pull the hose in the oil tank out (clean or replace, difficult to determine serviceability). Work your way through the linkage 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 probably left handed thread). Please make extensive notes & some digital pictures will help during reassembly. GL

If no a blunted, hooked piece of wire can be used to pull the hose in the oil tank out. Check the filter on the free end of the hose (manufacturer recommends annual replacement).
