Chain not lubricating on Ryobi 4046c chain saw

Manual says to remove clutchplate and bar to clean ports with a stiff brush. Can only find what appears to be the end of a rubber tube which is clear. Tried clearing tube with thin nylon wire which goes in for about 3-4 inches then sticks. still no oil - any ideas anyone?

Have exactly the same problem as you, think the oil pump is the problem but can't find a supplier for the part yet. I blew done the pipe into the oil tank using an air line and it was OK.

The chain lubricator not feeding oil

Harry, I would recommend first removing the chain and guide bar. The oil pump is not what you'd call a high pressure pump as it just kinda ooooozes oil out of the sidecase of the saw in line with openings like a slot, groove or hole in the guide bar. These slots and/or holes are notoriour for plugging up if the saw is not properly cleaned, maintained or serviced regularly. Chances are a good cleaning of these openings will solve your problem. If you have compressed air, that will work well. If not, and old tooth brush and a lot of hugging, puffing and blowing will be in order.

I have a habit of touching up the chains, and cleaning my saw(s) thoroughly after each use including cleaning the air filter, oil grooves, sprocket, guide bar and chain.

Where does the chain oil exit the tank and drop on the chain?

take off the side cover over the chain clutch/drive, don't forget to loosen the chain tension before removing, clean thoroughly, clean oil ports on saw and on the chain bar (little holes)clean the chain bar. Start the saw with the chain and bar removed and you should see oil coming from the port on the engine. Reassemble

Oil no longer lubricates the chain on saw groove and oil hole are clear

Sometimes saw dust and shavings block the oil port and track strip down the bar and chain there maybe a cover over the oil port remove this and clean carefully replace all remember to clean the bar put the chain on do not over tighten run the saw if there is no oil you may have damage to the oil pump this can happen if the saw was used with no oil or a blocked oil way some of the pumps will overheat causing damage hope this helps good luck

Oiler mechanism to bar of ryobi 40cc 10532 18 inch

I get asked this question a lot , im gonna have to make a video on this subject someday .
but here:
1st ck your oil viscosity/SAE it should be 30 and say bar/chain oil
next dump out entire oil tank and wash out with kerosene (you'd be surprised what I seen come out)
then remove bar and chain , locate oil outlet it's in body of saw near adjustment screw , use a small can of air to blow in this port softly , use a touch more of kero to clean this all out , refill tank with proper oil !!!! and run saw (no need to put bar/chain back on yet ) might take several minutes but oil should start to flow out hole !! stop saw and reinstall bar/chain then run again .. fixed !! if no oil comes out ever your oil pump is gonna need some fixing

for a low cost oil I use filtered used motor oil cut down with a dab of kerosene

Oil not feeding to the chain guide on the electric ryobi chain saw

Remove the cover on the right hand side of the saw and remove the bar and chain. Clean the oil port holes in the bar and the body of the saw. They get clogged with sawdust and chips. Also clean the groove in the bar and the sprocket at the end of the bar. Always use proper chainsaw bar oil.

Re problems with oil feed on ryobi 4046C, Oil is fed by worm drive and this becomes worn. Contact Augmented Agents on 0161 477 3388 and they will assist you with necessary parts. if you don't know which part ring 01628894400 they will e-mail you blow up plan and parts list. The drive cog is a left hand thread and can be nocked off with a drift of some description (I used a screw driver held flat) this then exposes screws to access oil pump

I bought a new chain to replace the poor one that comes with MY new 18" gas chain saw....but it does not fit into the groove on the bar....the new chain is too wide...the length is perfect though....does...

The difference is the gauge of the chain.The chain comes in .050, .058, and .063 gauge. I am sure that Ryobi does not offer but one gauge bar. This is just one of the many problems of dealing with the box stores rather than a full service qualified dealer. If you can find one in your area, patronize them. Not just when the box store lets you down but for everything. These type dealers are disappearing and are not being replaced and soon they will all be gone. If you can not find one in your area contact southern supply company at 205-833-2525 or email them at and I feel sure Jason or someone there can help you.

Need to know what kind of oil to put in ryobi chainsaw

If it is an electric chainsaw (not gas powered) then the only oil you need is chainsaw bar oil, which lubricates the chain and bar during use (self feeding system). This goes into the chamber at the top of the saw. You can buy chain/bar oil for chainsaws at any good hardware store or outdoor power equipment store. You can use any brand of chain bar oil, most are pretty good.

If it is a gas/petrol operated model, I will need to know the model number to advise on that.

Ryobi boasts a two year warranty. Have you contacted anyone about a warrantied repair?

An IPL (expanded parts list) for your saw with any oil system detail can be found here:
Homelite/ - Agree; Choose “Product Line”; “Select OEM” & “Select Catalog” both to “Homelite Consumer Products”. A drop down list appears; self explanatory from here.
The numbers Homelite & Ryobi use don't match the numbers everyone posts. A careful inspection of your saw should find something that matches.

Oil System Plugged.
Remove the clutch cover, bar and chain. Clean the oiler hole and channel. Start the saw and see if it oils when revved up. If yes reassemble your saw.
If no a blunted, hooked piece of wire can be used to pull the hose in the oil tank out. I recommend the filter be replaced. Work your way through the linkage cleaning and replacing any defective parts as you go. Carefully check the hoses for cracks especially at bends and connections. If equipped with an oil pump it is usually behind the clutch (clutch is probably left handed thread). Please make extensive notes & some digital pictures will help during reassembly. GL
