Chainsaw Sprocket Types - spur sprocket and rim sprocket comparison

[@magicone9327]

I recently changed a husqvarna 350 from its stock .325 pitch spur sprocket to a rim sprocket drive with 3/8" pitch so it now can use the many other 3/8" chains I have for my other brand saws! I can easily put on any number of different tooth count to increase or decrease chain speed or put on a .325 rim sprocket with original bar and chain if I desire to. I had to go after market but I got it done and no problems with the increase in pitch. Of course it now has a new bar to match!

[@crazykincardineite]

Did you use the original oil pump drive? I've heard some say it will work and some say it won't.

[@rodriguez131626]

How do you change the sprocket I have a car-490 and mine cracked I have a replacement but can’t figure how to get the broke. Piece off

[@bendangwapang989]

In order to put my 32 inches bar on my 24 inches bar chainsaw what size will be the Rim Sprocket?

[@stevest1300]

Thanx for this. Simple question answered without KZbin drama. Well done. The clutch drum says "Made in Canada"! I didn't think we made anything anymore...except limp wristed Prime Ministers

[@tomalophicon]

You're wrong. He was made in Cuba.

[@marcosvicente9865]

Question: I was running a Stihl MS261 and the rim sprocket broke. How could this have happened and how can I prevent it? It broke a section off but no deformation just like taking a bite off a donut. Sorry for the poor technicality

[@stevemcc4447]

Thanks for the video. I have an .058 325 76DL chain. It's hard to find that chain in Oregon brand anyway. Do you know which sprocket I would need to convert it to 72DL? Thanks!

[@MrBooMY3]

If you want to go to an Oregon bar get the .325 .058 Versacut bar but you'll have to get a 325 .058 78DL chain to fit it.

[@craigfield9447]

Thanks for your video and explanation.

[@Zuconja]

Hi, I have a question. Can you put a rim sprocket instead of a spur sprocket if the spur sprocket drives the worm gear for the oil pump?

[@magicone9327]

Iggy u referring to a husqvarna? If so yes u can

[@1d1hamby]

If you can get the clutch drum with the sprocket adapter for your saw you can. As far as I know nobody has come out with a 6 pin rim sprocket, yet.

[@magicone9327]

d hamby maybe not 6 but 7 are available via aftermarket. Depends on size of the saw. I got 7 rim sprocket, drum and bearing for husq 350 .3257 tooth. Presently waiting for 3/8 7 tooth rim sprocket for it. Which model saw are you looking for?

[@kamalhossain2702]

Who we attachment on simple motor?

[@timberray9572]

If your changing the rim sprocket to mount a different pitch chain, do you have to also change the nose of the bar? Thanks for any feedback.

[@chainsawbars]

Yes you do (unless it is a hard nose bar in which case if the gauge of the chain stays the same - the drive link thicckness - then you don't have to).... But really you would not do that - you would change the whole bar as changing the nose over means riveting a new nose on. It's easier to buy a new bar and swap them over.

[@timberray9572]

Thanks for the info.

[@dcano86]

Can I put the rim sprocket on a saw that has a spur sprocket?

[@magicone9327]

dcano86 change to a drum that accommodates the rim sprocket.

[@Ducktruckful]

I have a spur type on mu Echo CS400 will the same chain fit both spur & sprocket drum?

[@magicone9327]

Ducktruckful yes

[@magicone9327]

You most likely already know this after 2 years so I say this for those that are just now looking and need to know. The same chain drive link count works for both types so long as the count of link engagements are the same. Such as both are a 7 tooth or what ever count. The pitch has to be the same as chain and roller tip on the bar. Some rim sprockets are made for specific gages. Like .325, 3/8. 404, .058, .063

[@thisisyourcaptainspeaking2259]

I like the .250 chain on my small saws, smooth and cuts fast. Wish I could try out a rim with fewer than 9 pins, 8 or even 7 interests me. I'll have a look closer at the OD of the spline drive, this might explain why there are no smaller rims. 9 pin works pretty good in this case but I can tell the saw 32cc and under saws struggle a bit in hard wood and I suspect 8 pin might really be better in that respect. Also, many antique saws with gear reduction used a spur with internal 10 spines, like the MALL OMG for instance. Replacement sprockets have proven impossible to locate and I'm looking for a solution for this dilemma as well.

How can I tell the pitch of my sprocket without removing it?

[@chainsawbars]

You need to check the chain you are running is the easiest method www.chainsawbars.co.uk/chain-guide-bar-sprocket-identification/

[@calicano9095]

Can I put the rim sprocket on a chainsaw that has a spur sprocket.

[@900stx7]

I did with my stihl ms250. Oregon made one for about twenty bucks.

[@abowhand]

No, actually we could not see the rim sprocket. Great view of the spur sprocket though.

[@goodboyringo9716]

The spur sprocket lets the chain slid side ways but the rim sprocket keeps the chain in line.

[@1d1hamby]

Has anyone seen a 6 pin rim sprocket, yet?

[@manleyjoedesjarlais7568]

You never have to change a rim sprocket because it breaks into pieces. You just add a new one.
