Title: Poulan oiler 3400 3700 3800 4000 375 385 395 3.0 3.4 3.7

Being I dont know these  and may help others find info they need.  Share up what you know on the auto and manual oiler on these.

I was trying to clear up a guy trying to say these models didnt have auto oilers and I knew they did since owning the poulan 4000.

So are all the oilers the same with no updates etc.  Being I never had one apart. Pic of oiler parts I found online.

They have an impulse driven diaphragm type auto oiler.  It's in the same housing as the manual oiler pump.  The diaphragm is thankfully a simple one without any metal parts riveted to it.  Allows us to cut our own diaphragms out of suitable material if needed. 

There's a square section o-ring (called a quad ring by Poulan) in the manual oiler.  When it fails the oiler doesn't work right.  Sucks air and/or leaks.  AFAIK there was never any updates/changes to the oilers in this series.

Supposedly, the early 3400's had an adjustable auto oiler pump......................but I've never seen any evidence of that (in the SM, IPL's, in person, or in pics).

The ones that I have where the auto oiler did not work but the manual did turned out to be the diaphragm.  The only other thing I have done with them was to make sure they were clean.

The most recent 4000 I bought does not have the auto oiler working on it only the manual is working right now until I look at it.

I believe that's what it is called.  It is a small plunger with a spring that pushes on the diaphragm.  IIRC.

Hi Fellows,

I am looking at ordering up some of the material to make those diaphragms.  I've posted on AS and Sawhawgs in the Poulan forums and wanted to catch anyone here interested.  Let me know.

Cheers - Cory

Cory (hogwood) found that supply. Much more reasonable minimum ordre that the one I used whicj was Allstate which has recently increased their prices by 25 - 30%.

Ouch on the increase Tim for sure.

Welcome Cory and Thanks for sharing  with us too.

I know the material that Tim found worked great.   If this is the same it should be a winner.

A little late on this one fellows.  I should have shared the contact information earlier.  FWIW the material is excellent.


Here is the contact information.

Company and Sales Manager in Burnaby, BC: http://www.neseal.com/index.php?option=com_contact&task=view&contact_id=4&Itemid=224

Product: http://www.robco.com/content/view/339/87/

I was given the go ahead to post by the company. I was able to purchase a smaller amount and have it shipped. Thao said she can accomodate others when necessary. Give her a call.


I have been experimenting with making the diaphragms and find punching out the impulse and screw holes on either a cutting board/high density fibreboard work well.  I looked closely at those OEM diaphragms and it appears as though the holes have been fused around the cut edges after cutting.  I was struggling getting the small holes for the pegs punched adjacent to the button/pintle pump area, as the material is very tough.  I heated up a small nail in a torch until it were glowing.  Melted perfect holes.  I imagine a soldering pencil would work as well.

When I was making a few of those diaphragms I used a leather punch.   That seemed to work great for me.
