The manual oiler on my c-52 used to work, but has all the sudden quit working. I was wandering if anybody is familiar with this oiling system and what I should do to go about fixing it. Thanks.

There could be a couple of different things wrong that come to mind.What exactly is the oiler doing?Do you feel any resistance when you push the oiler?Do you see any oil leaking anywhere?Your oil line pick up could just be plugged.First thing to do is to drain the oil out of the tank,then make yourself a hook out of a stiff wire.I use electrical fence wire for cattle.Shine a bright flaslight into the tank & hook onto the oil line & pull it out if possible.Now inspect the oil pick up,it's a metal filter.You can take it off the line & clean it up good.I put it up to my lips & if I can blow through it I know it's not plugged.If it blows through fairly easily then you can put it back on the line,but inspect the line to see if there's a split or a hole in it anywhere.Next thing that I'd do is fill the oil tank about half way with either kerosene or diesel fuel.You can let it sit overnight,or just swish it around with the cap on.This will clean out any sludge that may be hindering your oiler from sucking up oil.Try this first & let us know if the oiler starts working again or not.

Ok I will try it. The Oiler doesn't pump any oil, and there is no resistance when trying to pump oil.

It sounds to me like the pump has lost it's prime.Clean the oil pick up,inspect the oil line.The next step might be to pull the oil pump rod out to see if the O rings are shot.I don't know too awful much about the C series oilers.I'm assuming that your saw has manual oiling only? Ed

Ok I'll do that, and yes it is manual oiler only

Inlet check valve may also be stuck if oil tank is dirty. Clean tank and filter.
Refer to figure 4 of C-52 Chainsaw IPL 24256 for component location.
Remove both check valves, spray brake clean and apply compressed air to oil passages including bar pad.
If that doesn't help the problem is the plunger o-rings.

I didn’t get a chance to work on the saw this evening but will be able to in the morning. I will try everything you guys said. I appreciate all the help guys. I’ll let you know what I come up with.

Also check manual oiler system for leaks. If a line is cracked, it will suck air instead of oil. Common cause when oilers suddenly quit working.

I worked on the saw a little bit this morning, but had to go and cut fire wood later in the morning and won't have a chance to mess with it the rest of the evening, but I took the plunger out of it and I'm thinking it would benefit from some new O rings, I dumped some bar oil down the hole that the plunger goes in and that seemed to prime the pump and it started pumping oil but i still don't think it is pumping as good as it should be. I couldn't get a hold of the oil pick-up line, so I will have to work with it a little more. I've also cleaned one of the check valves and am not sure where the other one is. I also need to clean the oil tank out, but don't have any kerosene or diesel on hand, would anything like gas, carb cleaner, brake cleaner, or lighter fluid work instead.

New o-rings never hurt, I figure 50+ year old rubber can't work as good as new. Of the items you listed lighter fluid would be the only one that I would use, the others all seem to harsh and may damage the rubber pieces. Since you've got it pumping oil now, I'd get some fresh oil pumped through and see what happens. On my C-91 if I run it all the way out of bar oil it takes forever to get the prime back.

Here's something else I thought of Garrett - I had the same problem with the manual oiler on my 450.No matter what I did it just wouldn't prime.I could hear it sucking air & it acted like it wanted to pump oil.I looked everything over several times before I found the problem.Where the end of the hose attaches to the plunger assembly the hose was bulged out just a little where it attaches to the metal.I took a pair of diagonal cutters & nipped off about 1/4 in.from the end of the hose,re-attached the hose back on & it began pumping oil immediately.The hose was simply stretched out from being on that metal piece for all those yrs.That might be what your saw's problem is too.It's a simple fix.

I may have to check that out, thanks for the suggestion Ed. If I have to clean the tank out I will probably try and use the lighter fluid, I figured it might work for cleaning the tank but just wasn’t sure because I have substituted it for gas when I have been trying to clean something off my hands that is tough to get off since it’s not as harsh as gas. I will take another look at the whole oiling system and look for possible problems. I also might get some new O rings for the plunger, would they be something where I should order the actual homelite part or just pick up some O rings at the hardware store? Thanks.

If you can't locate the correct size O-rings at the hardware store.. Leon has the ones required.
74388- plunger O-ring (1.99) 59074- shaft O-ring (1.99) A-57834-10 -plunger assembly(O-rings included) (5.99)..my choice 58340- oil hose (2.79)
I think gasoline would be okay for cleaning..just no carburetor cleaner.

Hey guys just figured I’d let you all know that I haven’t forgotten about the oiler issue, school has been very busy lately so I haven’t had time to do a whole lot. Spring break is coming up next week so I should get some time to mess with the saw and get the plunger out and get some measurements on the orings, and try and get some picked up at the hardware store or if I can’t find the correct ones I’ll get some NOS ones ordered. I’ll let you guys know when I get started working on the oiler again.
