Just like the commenter below me, I owe you big thanks! This explained to me what the forums could not do before I dug in to do the starter clutch on my 84 Honda CM250. Great instructional video
helpful video. however, i just did this for a '73 CL350 which has an identical starter clutch, and i have a few pieces of advice to offer: 1) use an oil filter wrench to hold onto the clutch while you try to remove the center bolt, 2) you can use your rear axel bolt to pop the clutch out instead of buying the puller bolt, 3) you can replace all the springs, caps, and rollers without taking the clutch apart (by that i mean not removing the 3 screws). just i used a small angled pick to do this. hammering the clutch with an impact driver may have cracked the first plate inside. it may have already been cracked, i'll never know, but regardless, you can change all the screws, caps, and rollers without even taking it apart. my bike now starts on first try.
Yeah. The kid thing made me smile and reminded me of how I miss those days when mine sounded like that. If I could do it over, I would give them my full attention and be cognizant that these days/years are fleeting. And then they’re gone. Sorry. A bit off topic. Thank you. Very helpful vid.
I orderd 3 springs, caps, rollers to rebuild my CL350 clutch. I should have waited till I pulled it apart. The rollers and caps were good, only the springs were collapsed. Could have save myself about $20 by only buying 3 springs. I assembled it without taking ithe clutch totally apart (the 3 phillips screws) as suggested in an earlier comment. A small flat blade screwdriver , a finger and needle nose pliers made it easy. I also left the starter gear and retainer in place. I also have my starter off for a rebuild which will be a cleaning of the commutator, new oilite bushings, brushes and brush springs.
Great video! Question, what is that sound at 13:08? The third time you started it, there was a binding noise? My k6 175 does that too, I was thinking it was a sign my starter clutch needed to be replaced, but if your brand new starter clutch is doing it too it must be something else.
That noise has to do with the crank and cam position in relation to letting off the starter. It's letting off the starter right near the spot when the cam is pushing on a spring, resisting rotation or even causing a slight reverse rotation a few degrees, while I've already stopped supplying power to the starter. The overrunning clutch then slips on the crank since it does not have enough power to fully engage or overcome the reaistance on the crank, creating the wonderful squeal. Hopefully that makes sense, lol.
averagerepairman Awesome. Thanks for the explanation about that sound. My 1972 CL175 has it also (when I use the electric start). So, am I safe in thinking that the sound is normal operation and not a sign of a current or potential problem? I hear it quite frequently on classic Honda bikes. Thanks you.
@@jasonzimmerman7379 The crankcase has to be drained before you take the side cover off. Or, you'll end up draining it as the cover comes off. He said he was going to use red RTV because he didn't feel like waiting for a gasket.
I just went through this process only to find that the symptoms persist after replacing impacted caps and springs. I am curious to know if your large chainring has any in and out play (mine does)? As well as the direction that you installed the small sprocket. CMSNL shows the small sprocket with a collar facing out buy I can't see that in your video.
This was quite a while ago but I do not recall any play in the large sprocket. The collar you speak of is indeed facing out, but the illustration on CMSNL is very exaggerated. If you look at the small sprocket within the first ~2min of the video, you'll notice a light colored ring that the chain appears to touch, but doesn't, that is the "collar". Since there is no tensioner on the chain assembly, these sprockets are installed at the same time, as long as they are coplanar, the chain will ride straight, and should start the engine. Another note, I never removed the sprockets for this repair so whatever way they were before is how they are now. You mentioned you replaced only the caps and springs, check the rollers as well, any flat spots or damage can cause the clutch to slip.
Thanks for the reply. I believe I installed the small sprocket correctly. I did have some play on the large chainring for sure, though. I can move in and out about 1/8" at least. I figured that was what the small retaining clip was for. I did no replace the rollers. I suppose I should have. After attempting this repair it seems to have fixed nothing. Side covers will be coming off shortly. Thanks again
Small update, I took the side cover back off to watch as I ran the starter,. What I found that my chain would deflect (much like yours but much worse) and hit anything and everything inside the case as it spins. So I have ordered a new chain and will see what that does for me. Rollers look good but they may be up for replacement if this doesn't solve it.
Do you ever hear rattling from the starter chain slapping the large sprocket retaining clip? I took a slo mo video of mine and you can see the slap action: ua-cam.com/video/W-U0b_Z3yVo/v-deo.html
Are you talking about just the small circle cover or the crankcase cover? I don't remember anything other than just the screws, I used a rubber malley to help break it free.

I've been looking for a video like this for a good year! Finally understand the starter clutch. Many thanks!
Excellent vid brother! Super cute kid thing too.

Could you share the bolt information shown around 2:10? I got the M16 1-1/2mm but hoping to confirm the length before I order it.

Thanks for this! Gonna try it on my '72 CL350 tomorrow. Hopefully get that sucker back on the road!
Thanks for sharing the video on cb175 starter clutch. How do you rectify that squeal when using the electric starter?
Such a cool lil' bike!
Awesome video. I take it all those "Phillips" screws are actually JIS screws?
Thank you, I learned a lot, very useful, cute sounding kid

Do we need to drain out the engine oil before removing the starter clutch assembly?
I also have the same question, also did you get a new left gasket or reuse the old one?
@@jasonzimmerman7379

nice share bro. did u have a video how to assembly kickstart spring. i keep broken it twice. please share if u have it. thanks

Is there any trick, to get 'the starter clutch' cover off? Took out all the cover bolts, but something still holding cover-on ? ? ?
Are you talking about just the small circle cover or the crankcase cover? I don't remember anything other than just the screws, I used a rubber malley to help break it free.
You're getting resistance from the permanent magnets in the rotor being attacted to the stator in the cover.
Wiggle it off.
Anyone know if it can still function with a few of those broken tabs? @3:45 I opened up my case and found only a couple still intact.
