Replace rim sprocket?

[stihlrookie]

Well after reading a couple threads regarding this I thought I should replace the rim sprocket on my MS362. The saw is 4 years old and I have ran 3 or 4 chains on it. I checked the sprocket visually the other day and I can see a bit of wear from the links of the chain so does that mean its time for a new rim sprocket? I also bought a new needle cage bearing to put on, figured it can't hurt since I am already there. What type of grease, if any, should go on the end of the crank with the bearing?

Probably past time for the rim. I wipe Oregon sprocket nose grease on the bearing before I put it in.

How much do you have left on your chains? If you have some life left and the rim isn't deeply worn I would wait till you get new chain. Just use any clean grease you have on hand.

I have one chain, 84dl, that is down to nubs for cutters. 1, 84 dl, that has about half left and 2 others that are still in good shape. Probably have 30-40 cords of firewood cutting on the saw with those chains.

Often the rims have wear indicators on them.

When you can't see the indicators in the section where the chain rides then it's time to change. If your rim doesn't have this then it's a little more difficult to tell. The rule of thumb is typically swap it out every two chains, depending on conditions and use. Some last longer than others in different situations.

Also on a worn rim you can see where the drive links of the chain are sticking through and are making contact with the clutch drum if you look.

Rims are cheap to replace. So for the peace in your mind just do it.

Looking at the picture TK posted with the wear indicators I would say my rim sprocket is worn, but just barely. I am going to replace it. As far as being cheap, I expected $4 or something like that. Certainly didnt expect to pay $8. Thanks guys.

If the rule of thumb is one sprocket for every two chains, I've seriously been doing something wrong. I run oregon chain so maybe they really are softer? Not saying it's wrong just not so in my situation.

It says Stihl on the side, if you got a Oregon you could have probably paid $5 or $6

Straight outta the Oregon book. I'm sure they want to avoid problems, riding the fine line between worn to the limit and causing other damage. To someone who has more experience it's not such a big deal to swap a rim halfway through a chain, but it's easier for the lesser experienced to be on a 'maintenance schedule' of sorts.

Don't know the prices in the US, but here you pay ~950€ = 1250$ for a 362. And you complain about 8$ for a new rim?

If you plan to run the same worn chains, keep them together with the worn sprocket and save the new sprocket for a new chain.

As chains wear they "stretch" and running a worn chain on a new sprocket will almost certainly causes excessive and premature wear on the sprocket.

It will, and chains usually cost a lot more than sprocket rims - so the rims are the wrong place to save money.

+1..what Mark said..!!

Run old (but not worn-out) sprockets on old stretched chains..

Run the New sprocket only on New chains when you get them.

Well, maybe I will let that rim go a bit longer. The only worn areas are what you can see in the pics, maybe 1/32" of wear. The rim is not worn down inside where the drivers hit and there is no visible wear on the splines on the clutch drum. I have a new loop of Stihl RSF so I will wait to swap the rim and run the new chain with it when I do. Thanks again all.

$8 sounds like local dealer prices.

I pay $3.90 a piece if bought single and if you get 10 or more $2.50 a piece. I just add them in with a larger order and keep extras on hand for me and others.

Yeah, I also paid $10 for two NGK spark plugs and waited almost 3 weeks for them.

Don't forget the grease in the meantime.

WOW; time for a new dealer

I just pick up a new rim about and hour ago for the 026 I just got and it was under $6.50 (small spline) and I pick up a large spline last month for under $9.00 (all Stihl rims by the way)
