Need Help with Oiler on Homelite 150

[jkn]

Hello there,
I am a third generation owner of a Homelite 150. The oiler hasn't worked since before my dad got it so I have never seen it work. It's a good saw so I want to fix the oiler so my questions are:
1. What is likely wrong with it?
2. How do I disassemble it to get there?
3. Is the part likely available anywhere?

Thanks,

John

Hi JKN, Welcome to the "House"!


The problem with your saw could be the pump diaphram or a clogged oil line/filter.


I may have a pump for your saw or just the diaphram if thats all you need. You can look up your saws IPL in the IPL thread and give me your P/n and Ill see if I have it, or just post your UT# and Ill look it up for you.

Heres the link to the UT thread.

You will probably have to remove the engine from the case on that saw to access the oil pump. The engine is removed by first removing the carb and then removing the 4 case bolts that hold the engine in the case.

If this saw has an impulse line (?) this could have failed also. If it does have an impulse line you may as well replace it while you have the saw apart.

Eric,
Thanks for the help. The UT # is 104002. I didn't find this on the list but the UT 10400 parts list looks like the right one. Any help on removing the carb? It's not obvious to me and I figured I would ask before I just start unscrewing things until I find it. It's not just the two behind the air cleaner is it?

Thanks,

John

Have lots of experience working on the 150. You have to split the case to get to the carb (and to repair the oiler). The two screws in the top of the case and the two screws in the bottom of the case and the two carb screws, under the air filter, that you mentioned, must all be removed. A screw driver is inserted thru the slots in the starter and the starter screws and starter are removed. the case is then separated by grasping the two handles and pulling apart.
I also sent you a PM.
Good Luck.

To trouble-shoot the 150 oiler:
PRIOR TO TAKING THE OIL TANK OFF
Remove bar and chain...If saw has oil feed rate needle, close tightly clockwise.
With oil in the tank...idle engine for five minutes
if pump has good output...drain most of the oil and repeat five minute idle to ck for leak in inlet line.
if oiler does not pump...ck inlet line and fitting for leaks.
If oiler outpit is greater with needlevalve open than closed, oil is gravity feeding and the pump is not working.
If after five minutes operation there there are bubbles or oil appears emulsified there is and air leak in pump assy.

Try these tests before opening the saw.

The oil output has been zero for at least the last 15 years. The only way oil comes out of it it through the fill hole. I am hoping it is just clogged somewhere. I will let you know what I find when I get a chance to mess with it. Leaving for the weekend so it is going to be a while. Thanks again for the help.
