Chipper Chinese Chipper Review

DIYGuy - You've described the part a lot better than I did. I like the trick with the belt tension thought. I have had the feeder bind up, and make the belt smoke, but it could have also been putting a lot of force on the balljoint. I'll let you know what I find out from the dealer. There wasn't any debris behind the joint, only grease, but it does merit mentioning because that could also put force on the circlip.

I disassembled mine today and took pics and notes. (Posted all in a new thread). I found the the circlips on both ends of my shaft do not have any wear patters on them, and there is no corrsponding wear on the ball nubs either.

I knew the spring was important to the assembly, but I didn't understand how important until I took it all apart, hence, the new thread and pictures.

If you have any questions that I can help with, let me know.

Based on your pictures, I've got to believe that either:

1. Your slip joint in the middle of the shaft is binding, causing the ball to be pulled back against the circlip

or

2. The socket end of your upper ball nub has way to much play in it, causing the upper ball nub to rotate too far in the socket at the end of the drive shaft.

DIYGuy - My thought is that your second statement is probably more accurate in my case. Everything seems to move freely, and the spring is doing its job. I think what happened is that when it bound up once, it just happened to be on the nub that allowed enough clearance for the socket to pop out, and the damage to the clip occured by the ball trying to snap back in, with the help of the spring. I think your earlier statement about belt tension is something for the other owners to take note of. It is sure a lot better to have the belt slip in a jam situation, than to have this happen.

I still need to get the old clip out of the socket, which I think I have devised a way to do. However, getting a replacement clip is posing a problem. Checked with some local sources, and they haven't seen anything like it, and Gary doesn't carry anything but blades for parts. I'll do some more searching, but if anyone has any ideas on where to find one of these circlips let me know.

If you can't find anything local then do a search on "Google" or your fav SE using circlip. Google had all kinds of places listed.

I think you might find the snap ring you are looking for here

Ken,

Is there any way you can show what you described in photographs? I want to be sure mine is correct when I get it.

Also, excuse my ignorance but what is a circlip? Is it like a retaining ring?

This may seem a little odd, but Lowes (hardware dept. - nuts and bolts) has a drawered section of "hard to find" gismos. You would be surprised what I have found there that I couldn't find elsewhere. If this is a snap ring they probably have some, its just a matter of size.

I had never heard the term circlip either. I did a quick search and it looks like I have just been lumping all 'snap rings' into the same category.

I noticed that: http://www.tractorconnection.com/ sells Jinma out in Oregon. Maybe they stock some parts for these. It might be worth the call or email.

See if this is on the order of what You are looking for: Circlips

Yes. I always thought of the circlip as a snap ring without the plier holes.
