Title: 6401 oiler
Post by: treeslayer2003 on October 21, 2015, 07:22:51 pm
can y'all help me with this? i have no clue where to get parts and have never worked on a dolmar. i assume i need a husky socket to remove the clutch and probably some kind of kit for the oiler.......it just quit all together.

The Husqvarna 372 socket will take the clutch off.

@Nathaniel Vansickle on this forum can furnish you parts

jared did a really good thread over on AS. http://www.arboristsite.com/community/threads/dolmar-makita-oil-pump-upgrade-modification.264696/ look through it and see if that helps. the little nub on the plastic piece is known to wear/break. repair kit is NLA so you either have to modify or replace the whole oil pump assy.

it seems logical to me that that plastic nub is probably gone. i can handle the plunger grind but is there no replacement adjuster available? did mr. Jared make them for sale?

The have been NLA for a couple years but i just checked the new Makita crossover and they are available. Apparently Power Distributors just didnt want to stock them.

I am sending in an order tomorrow if you can wait a few days. We dont have availability/stock  from makita right now. just what a crossover page tells us. It says the oiler rebuild kit is a valid part number but since it has been NLA from PD for 2-4 yrs i dont trust the Makita site. Lets find out if it shows up with my order. I have the lines and a complete pump in stock but that rebuild kit is 1/4 the price of the pump.

ok, i finely got around to doing this. pretty simple and i did steepen the ramp on plunger just slightly. seems to work with plenty of flow but i also have some air bubbles........is this a dolmar thing? never noticed this on stihl or husky.........
