The gears are fine. It's the bearing and/or the bronze bushing that holds the gear. The bearing is a 6000 2z. It's a sealed bearing. It can spin fine but the clearance is shot. The bearing can be pushed out from the inside. The lack of grease in yours, I'd bet it is the bushing. It can be removed and replaced. Tractor supply, Lowes, home depot sells them. I can't recall the size right off hand. I think it is 10mm od, 10mm long, and 6mm id. Change the bearing and bushing. And grease the hell out of it. $10 fix.

[@LastHumansGarage]

damn, wish you had posted 2 years ago, threw this in trash long time ago

[@kimchee94112]

Agree, most lightly bad bearing from the sound of it.

[@canadianryan3875]

Under that black ring it's a unsealed bearing from the looks of it. a few drops of oil will help cleaning all the dust out of there helped

[@LastHumansGarage]

i took it apart again, lubed it all, noise is even worse. very strange. its a mystery noise. the bearing spins smooth with no load.

[@tdogj2084]

I had a kick back on my p505 from cutting Pvc pipe and it makes a horrible sound now!

[@LastHumansGarage]

lol bro!!! I used mine for concrete and now it grinds and sounds horrible!

[@SupraWes]

Its probably the bearing, cutting bricks would have put excessive strain on it causing it to get loose, spinning it with your fingers is not getting it going fast enough.

[@LastHumansGarage]

prob right,ill replace it at some point. (the saw not the bearing) there are 3 bearings in that unit. 2 in motor side and 1 in gear side

[@zijie-he]

I burned several such 5.5 circular saws. Add some grease into the gear box, it can work for another while. But eventually the motor will die. For a circular saw, the brush motor does not last too long. I have got a brushless one for 109 I remember, it's much better.

[@LastHumansGarage]

great tips, thanks bro. i think i may have that one now?? i bought a new one a few months after this video, but dont remember the model. may have got the cheaper one again tho..

[@stevenmadsen53]

It's the sprocket. The metal is soft. If we can get a new harder replacement it will work

[@LastHumansGarage]

yes i already replaced the sprocket once with brand new. no change.

[@Scotty_in_Ohio]

Ryobi's warranty is actually pretty good - I'd at least try to get a new tool vs. just buying a new one. I have the older (blue shell) version - I typically only use it to cut a quick 2x4" - much more and I get my 7 1/4" electric saw out.

[@LastHumansGarage]

hmmm maybe i should try and get my ryobi warrantied

[@SoCalKevin]

Mine started making this noise after ripping 3 sheets of plywood and about a dozen crosscuts on 2x4's. Really disappointed in Ryobi durability. I have a dewalt 28v that is about 11 yrs old and even the original batteries still work. Bought the ryobi because I could have bought 3 of them for the price of one dewalt 28v replacement battery

[@LastHumansGarage]

ya they are pretty sucky.. but... ill prob buy a new one, since i dont do much wood work anyway

[@jimmyhallhallowen937]

Yea just bought 6.5 saw just because I have a few batteries for my recip. Saw so I thought I just get something so these bat. Aren't lying around and out of box loud ass noise very disappointed

[@faust1639]

Trust me I fixed mine sounds like new now i regressed mine where both gears touch and filled the upper area where it's hallowed areas also all the way so sound won't travel. Wow what a different.please do a second video with this method

[@LastHumansGarage]

Thanks for sharing

[@davidleeetheridgejr8952]

Syracuse NY my saw P505 makes the same noise I think unfixable? HELP,or Just gotta buy a new one but by the way it’s an awesome tool I love it

[@LastHumansGarage]

not really fixable brother.. i wasted money on parts and then threw it out.. and bought a new one..

[@mikedorosh4605]

Mine had the same problem.Going back to the land of Ryobi and HD.Made in China HD promotes this brand like crazy,so they should warrant it.

[@LastHumansGarage]

ah not if you use it on concrete which is def mis-use...

[@arkansasmountainman]

ereplacementparts.com carries parts for tons of equipment. They have videos on repairs there and here on youtube. I just found out I can fix my ryobi corded circular saw for under $10. My saw is making the same noise. You should try some grease on the gears and a good cleaning throughout (remove and replace all lubrication). If you can't get the noise out, just use it until it quits. Watch for blade wobble. The brick dust might have gotten into some place and caused wear or the grinding. That would void your warranty anyway. Plastic saw, only good for light work!

[@terryt4GM]

You could use a drill to turn the gears, see if it makes noise at high speed

[@g.b.5206]

Thats is the spindle dude

[@LastHumansGarage]

cool!

[@frankmontez6853]

Hey , you got any idea what's causing my saw to cut off after a few seconds being turned on ? I guess it's etheir the trigger switch or motor ? Don't even get to put it into lumber it just cuts off

[@LastHumansGarage]

hmm.. interference in mechanical. as long as your batteries full

[@frankmontez6853]

@@LastHumansGarage yes new 4 ah battery . What do you mean by interference in mechanical??

[@austinb7566]

Good viceo

[@LastHumansGarage]

thancs

[@jimmyhallhallowen937]

Just bought p507 6.5 literally out of box after I checked for sq. I put a battery in and same issue you have

[@LastHumansGarage]

a new one?? bruh....

[@jimmyhallhallowen937]

Yep

[@BaggerJay]

Mine makes the same noise. I think it's the gear lash. Mine was fine until I jammed it and the noise was there after.

[@LastHumansGarage]

i should just suck it up and buy a new one.. can't really sell this mashed one for even $5 without feeling bad..

[@LastHumansGarage]

and i think youre right, its gear lash. those are cheap soft gears. can't think of any way to make them thicker really.

[@seawalkersee]

Spindle/gear assembly. Check the runout on the blade and see.

[@CharlesNolanArt]

I bought a remanufactured Ryobi corded circular saw and the blade kept stopping, I realized the thread for arbor screw is upside down so it loosens itself during use. Ryobi quality has like everything else gone way down.

[@LastHumansGarage]

hmm which screw is an "arbor" screw, ill check mine out too. i just used it today in fact.. (not the saw in this video.. i threw that out long ago, i have a more modern ryobi now.,)

[@CharlesNolanArt]

@@LastHumansGarage I was talking about the main blade screw, sorry for the confusion. I gave up on it for safety's sake but it does bug me.

[@Scotty_in_Ohio]

It's possible too that you've just worn down the gears or the bearings in the motor itself are worn and with no load it doesn't make the sound.

[@LastHumansGarage]

Ohh I didn’t think about that.. a new saw is $70, I’ll prob just buy one. I use it to cut the branches on trees I trim

[@arpxxxxtraffic]

Mine did the same thing after hardly using it. Replaced it with a larger model in hopes Ryobi holds up.

[@stevenmadsen53]

YES. Just reGrease the gears

[@LastHumansGarage]

ah didnt work. but you prob knew t5hat after watching the video.. i STILL havent replace it.. only cuz i dont use it too much..

[@Bjukemen]

Motor RS 775 ?

[@LastHumansGarage]

ya

[@rickcasillas6629]

It happened to me cutting pvc, ordered parts from ryobi less than $20.00

[@LastHumansGarage]

I didn’t know u could buy ryobi parts

[@LastHumansGarage]

i ordered both gear parts for $10.. ill see if it works!

[@RLMJRJEEP]

@@LastHumansGarage Mine started this today after being pinched during a 2x4 cut. Did you have any success with the parts?

[@LastHumansGarage]

@@RLMJRJEEP nope.. so its my motor.. not gonna buy even more parts. the gears didnt help anything.

[@RLMJRJEEP]

@@LastHumansGarage Damn. Guess I'll have to pick up that larger model for a replacement. Thanks for following up with me.

[@donaldgeorge6656]

I would to it’s best to upgrade

[@LastHumansGarage]

ya. but i don't really need it now.

[@donaldgeorge6656]

$49 on Amazon

[@LastHumansGarage]

damn.. well i wouldn't buy another 505 with the 5.5" blade.. that's like 2 generations old. i'd pay $69 and get the 6.5" current model..
