Homelite Ryobi model conversion
By: DeplorableAmerican Date: April 20, 2018, 10:00 pm
---------------------------------------------------------
I got a Ryobi (C4620) RY10520 , S/N ATN3020498. That is having
auto oiler issues. I have cleaned the discharge port, lightly
pressurized the oil tank, checked the discharge port and put a
mighty vaced the discharge port. I am assuming that the pump is
bad. Getting to the pump seems to be impossible. I removed all
the external screws with the exception of the 4 engine mounts
screws. It looks by the diagrams that the oil pump mounts
underneath and is situated length ways front to rear. Between
the block and flywheel. I thought i could remove half of the
outer shell and gain access.
I wounder if i can find more information by looking up the
homelite version? Not sure what homelite model number would be
the mirror of the Ryobi?
Its a Ryobi (C4620) model number RY10520, serial number
ATN3020498.
any help would be greatly appreciated.

Check and see if your worm gear is stripped.

Hi cut4fun,
I have the same pages saved to my phone with the exception of
the homelite one. Thank you for your assistance. I plan to work
on it Sunday. The ryobi seems to cut smoother then the polan
wild thing i own. It looks like from the diagram i will have to
remove the engine from the shell to get to the oil pump. To bad
it dosent have the pump behind the chain gear. That would make
it so much less of a project.
The next time i buy a saw i am going to check the diagrams to
check the ease of service issues like this issue.
Thanks again for your help.

Try changinging the Ryobi model number to a Homelite model
number by substatuting RY with UT.
So RY10520 becomes UT10520.

Doesn't work with every Ryobi saw because there were way more
models of Homelite that have no Ryobi equivalent. Unfortunately,
it will probably take you to almost identical parts lists.
Decals and plastics will vary.

Got my new bar oil pump today. Plan on installing tomorrow to
cut on sunday 70°. I thought i read on here somewhere to wash
out the tank. Dose anyone have the link that tells was if any
soap to use? I thought about running light weight oil thru the
tank and pump first?

I dont clean tanks unless someone ran crap used oil in them.
Then I rinse with mix or kerosene.

A good rinse couldn't hurt. Splash of gas, a good shake and pour
it out.
I pour the remains in with the gas going though the riding
mower. The old Briggs can use as much lubrication as it can get.

Thank You Cut4fun and deezlfan for your responses. I failed to
mention that when i drained the tank before that a very few
pieces of what looked to be of the same black plastic as the
pump were floating around in the old bar oil.
I drained and flushed the tank out this morning with mix fuel
befour checking my email. After filtering the mix fuel flush i
found 3 more pieces. I have no idea how they would get in the
tank but there they were.
Thanks again for your help and advice gentlemen.
