Backwards to the rotation of the motor, all you need are basic tools to do this.

Mine did this when nearly brand new. You likely have a nasty jam of oil and sawdust stuck between the chain brake and the flywheel. It can be loosened by either careful prying of the case or precise shots of carb cleaner up in the housing. While you are in there look for a buildup of oil around the chain brake connection to the kickback paddle.

SOURCE: ryobi chainsaw pcn4040 - oil not being pumped onto

C. Both A and B. Is it the original bar? Has it ever worked with this bar? Yes continue, no reply below (first). Is there an oiler adjustment?
I know you did this, I have OCD. Good on you for checking.
Oil System Plugged:

  1. Remove the clutch cover, bar, and chain, clean the bar groove, any holes and passages on the rear of the bar (both sides, consider rotating the bar), if equipped with a sprocket nose ensure it rotates easily at least one complete revolution. Clean the saw oiler hole and channel. Insert a blunted, hooked piece of wire through the oil filler hole and pull the hose in the oil tank out. Pay attention to the screen or filter on the free end (clean or replace, difficult to determine serviceability). Start the saw and see if it oils when revved up (oozes down side of saw). If yes reassemble your saw. If no, continue with 2.
  2. Work your way through the linkage (use IPL to identify components and locations) 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 a left handed thread). Please make extensive notes & some digital pictures will help during reassembly.
If it does not oil on completion of 1 it is most likely a bad oiler or worm gear (see IPL).

I did not see a match to your model. If you can find it the exploded parts list with disassembly/reassembly. Also provide part numbers, where components are located, very helpful.
Homelite/Ryobi.com (authorized parts supplier)
https://www.gardnerinc.com/recons/disclaimer-lg.php - 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 do not match the numbers everyone posts. A careful inspection of your saw should find something that matches.

The 3 models I found all had inboard clutches and the oil pump behind them. Start with this:

The C-clips tend to fly when being removed. Please wear eye protection and exercise care.

Continue like this with the remaining pieces.

  1. Check the IPL for your saw to see if any special tools are needed. Poulan (Craftsman, Jonsered, Husky) clutch removal tool part number 530031112 if needed, is under $5 from many sources (look at the visible area between the weights if 2 small round sockets are visible you need the tool).
  2. There are metal piston stops available, when square (almost never) with the piston top these work well, if not square they have been known to punch through the piston. I suggest a length of nylon rope (nothing left behind) be used instead of the piston stop (retain 6" ± so you can remove it). Make sure the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and damage the piston as it rises.
  3. Everyone I have ever removed had a left handed thread (tighten it to loosen it).
If you have more questions or need additional help please reply below and I will get back to you. Thank you for using FixYa and Good Luck. HTH

How to remove clutch from ryobi 20

Not pumping oil to chain, bought a new pump and oil pickup but I`m not sure where the oil pump is located and what I have to disassemble to get to it.

Most oil pumps are situated behind the clutch and sprocket, these will need to be removed before you can acsess the old pump, if it has an inboard sprocket you will need to remove the clutch first, these are a left hand thread and just spun onto the crankshaft, they need to be jarred off against the compression of the saw, you may need a special tool if there is no nut on the outside of the clutch, this tool fits most Poulon clutches 530035560, once removed it is a fairly straight forward job to change the pump.

Ryobi 4450c clogged oil passage

HI There I have the same problem with the same chainsaw. I have stripped mine down and it's fairly simple to gain access to the oil pump. Mine has turned out to be the worm gear that turns the pump and possibly the pump. I am going to replace both but can't find a supplier for the pump and worm gear, if anyone can help me with a supplier that would be great. As for stripping out the pump you have to remove the gear wheel to do this you have to remove the spark plug and insert a tool to stop the engine turning while you tap the gear wheel off. there should be an arrow on the gear wheel but it will be a left hand thread. once this is off thereare a couple of collars around the shaft that will slide off then there is a couple of screws to take a plastic plate off this has to come next. once this is off there is the worm that is like a washer that sits on the shaft and rotates and has a thread on the underside that turns the pump. then there are two screws holding the pump in. Hope this helps.
