Sounds like you're not getting enough oil to the chain. Basically you've got an oil pump, pickup and filter involved in getting oil from the resovior to the chain/bar. If you cleaned the obvious area and the chain is not coated with oil, you may have a clog further up (inside) the oil delivery mechanisms. Also, drain the oil from the tank, and see if you can "blow" air through there. With the saw running & pointed down, you should be able to see oil on the ground being slung off the chain, if not, you are not getting enough oil to the chain.

How do you remove a clutch drum on Poulan Pro PP4620AVHD chain saw


YouTube can be a great help with video's of 'how to' do things.

I have attached a video from 'donnyboy73.' I found his video's to be very informative and well put together. The video link is not of your exact saw but is a Poulan and I hope will be helpful to you.

Chain doesn't move


Sounds like the clutch is slipping due to oil collected on the inside of the clutch drum. Wash out the entire clutch assembly with spray carburetor cleaner and let dry. Make sure the chain can be turned freely by hand, but the chain doesn't droop from the lower bar edge. Hope this helps!

With this; “Handle, Chassis & Bar Assembly” print; item 67; ChainBrake Assembly; $21.83.
You also need;

  • “Engine Assembly” print; not illustrated; part number 545006011; Scrench; $9.75.
This is the configuration professionals have used forever. The only thing to remember here is to hold the nose of the bar up when adjusting and tightening the bar nuts.

The dash number of your serial number is the type.
I think this is the what you seek:
http://www.ordertree.com/modelinfo/PWE/PP4620AVX-Gas-Saw/75.PP4620AVX-Gas-Saw.1.59.1.html
The "Handle, Chassis, and Bar Assembly" detail
Items 63 through 69 are parts, I think item 70 is a complete assembly ($22.78 without a kiss).

Your saw without tooless adjustment.

The "Handle, Chassis, and Bar Assembly" detail
Item 64 (complete assembly) $2.53.

If my saw I'd ask if it can be modified!!!

Poulan Pro 42/18 gas Chain saw: The chain oil hole that feeds the upper slot seems to be blocked. Does that rubber assembly just pull out or does the whole area have to be taken apart. Is it gravity feed...


GS, there is a pump driven by the clutch sprocket/drum. Operate the engine with the bar off. There should be oil coming out.

a) If so, the hole in the bar is plugged with saw dust. This is very common on all brands of saws.

b) If not, then remove the clutch/drum assembly and inspect the worm gear drive of the pump.
*note, the threads on all chain saw clutches are Left Hand reverse threads.

Oiler thus not deliver oil to the chain


Take the chain and bar off and run a small drill by hand into the hole where oil comes out. If it is not blocked you can "stretch" the hole a little bigger and hopefully resolve this.

Bar oiling problem


Just a thought: Is it cold where you are? At this saw mill where it is my job to keep chain saws running, learned years ago that you cannot use "bar oil" in winter. Need thinner oil, like motor oil. ....preferably a "non-detergent" motor oil, plain 30-weight is OK, HD30W will work, but the HD part causes the chain to stretch more so than standard bar oil. The bar oil literally is so thick in cold that it stripped the worm gear out of a Poulan Pro oil pump (plastic gear, anyways, wasn't much to begin with.) But thought you may want to try thinner oil, if it is cold where you are. Oh yea we also have 2-Husqvarna 359's with 20-inch bar, and use thinner oil in winter. Our Husqvarnas have an oil adjuster located on bottom, on clutch side. Straight slot screw adjustment.
