Starter Clutch Problem (with pics)

  • Thread starter Thread starter OriginalOwner
  • Start date Start date
Yep, I see them. They're a touch bigger than the bolt that holds the "rotor."

So, if I knew the correct size, I could screw the bolt in and it'll stop on the crankshaft, thereby pushing off the "rotor."

The "spacer" you speak of is to protect the crankshaft from the bolt and could be something as simple as the right sized washer, right?

A washer that fits perfectly in so the bolt doesn't mash-up the face of the crank. Correct?

:confused:

the spacer would be to add length..
a regular bolt will not have threads all the way up so you need to compensate..plus it would protect the crank/threads ect..
a washer won't do it..needs some length.
i have used allen bolts before..just depends on your id/od sizes you have.
maybe 8mm or 5/16 allen bolt..can't say for sure.
 
yeah i ran it through the "will it fit your bike" at the top and it came back, but the M16x1.5 is wat the specs are on the actual one. its half the price of the other ones.

Thanks fellas for the help. I understand SO much better what I need and what I need to DO than when I started this thread earlier.

I really appreciate it.

starter clutch

starter clutch

The starter clutch looks to be smashed :(, the body where the three rollers and springs are fitted. Buy a replacement, the hardest part of the job is getting the bolt out of the end of the crank and removing the rotor and starter clutch :eek:. You need an impact gun of some kind.
 
Well, I know what I need -- a M16 x 1.5 hardened bolt about 3 inches (80mm) long, I just don't know where to get it...locally.

Tried Home Depot, Grainger and Sears Hardware to no avail. They all have beautiful M16 x 2.0 bolts -- but no 1.5's.

I'll keep trying but I'm probably gonna have to order it online and wait.

:cry:
 
No Ace Hardware or a bolt shop?

You're faking me out with the "New York". I always think of that as NYC, since that's what they call it there!

I was thinking you're in NYC and could go to a bolt supplier

Is that the size of the swingarm pivot bolt? people have used that on some bikes

I'm about 8 miles from mid-town Manhattan.

I didn't even bother with Ace because their website says they don't carry it. Then again, Home Depot's website said they have it but they didn't. Go figure.

Tried a few "bolt supplier" places too, no luck. So, I got frustrated and ordered it online for $10 bucks delivered.

It'll be here Saturday.

Now I gotta find the clutch -- most of the sites are saying it's not available new.

Push forward! Thanks guys!
 
My Motion Pro 08-0027 flywheel puller arrived today -- it doesn't fit. Too big.

Multiple sources sited this as the correct puller so I never measured the opening. Stuck my caliper in the hole just now and against the top of the threads it measure 12mm.

Any suggestions? I'm lost and frustrated.

:mad:
 
Nevermind.

I used a ball bearing and the front axle bolt off of a 1975 Yamaha RD350B. It came off pretty easy.

The clutch is indeed cracked.

Which brings my next headache -- where can I get this part?

So far, I've checked all the usual OEM sites and the part, as a set, is discontinued. Even stranger, the part itself, the exact piece that I need, is not even annotated on the diagram?

This is a tough one. Any help is greatly appreciated.

:confused::(:confused:
 
In case anyone is following along for advice while doing their own starter clutch, here's something kind of important:

I ordered the correct puller as referenced by Motion Pro 08-0027 (M16X1.5 Rh), waited anxiously for it to arrive and when it did, it was the wrong size. Motion Pro's reference information is WRONG.

I believe the correct size is 14mm x 1.5 Rh.

So, I got frustrated and used a short bolt (axle) and a ball bearing as a spacer after reading the suggestion here at GSR. Following that suggestion flattened out the first thread on the inside of my crankshaft (red arrow).

I re-tapped it and it's fine now but it was pretty scary thinking about having to drill and helicoil or worse even, having to tear down and replace the crank if it was too messed up to fix.

It also wasn't fun having to spend the money and take the extra time to go find the odd size tap (12mm x 1.25) which none of the common kits contain. And just because I was able to dodge a bullet, doesn't mean you will -- be careful!

VERY IMPORTANT: If you must use a spacer, use one that sits exactly FLAT on the rim of the crank (yellow arrow). Anything else is completely unacceptable.
