Hardinge HLV - Broken and looking for diagram

[BJinaTJ]

I have a Hardinge HLV-H. The handle that sends the carriage left and right when threading does not work. When I purchased this machine the gearbox on the left was disassembled. I was able to get the gearbox together and the lead screw not turns as it should. I am not sure exactly how the lever actually connects up to feed the carriage left and right. It appears that there is a gear that can be pushed left and right from the rear that will get it to go left and right, but I am unsure how it all connects up.

I am wondering if anyone might have an exploded diagram or any insight that may be able to help me out.

Thank you for your time!

You really should have as much documentation for your lathe as possible. This would include the Operator's Manual, Service Manual, Parts List, & Wiring Diagram. Join the Hardinge Lathes Group on Yahoo. In the files section you can locate the operator's manual posted by me in 3 parts. Look for a file by Modamag and you can find a good Parts List. I haven't taken the hours it takes to scan a service manual yet, nor do I know where one is available for free download. Personally, I have spent hundreds of dollars on my Hardinge documentation. One of the items I purchased was a CD from Hardinge for around $150 that includes everything I mentioned, but it is for the later model lathes (much of it is the same for the older models). The manuals on the Yahoo group are for early model HLV-H lathes, and should be just what you need. Send me a PM with your email, and I'll see if I can help you with what you don't find.

The "gear" you mention is actually a dog clutch that is shifted via a fork attached to a rod attached to the left-right lever. The long shaft has a 1/4" hex for an allen head wrench which is used to screw the shaft into the floating block under the headstock and on the shifting shaft linkage.
If these parts are missing, I have some used items available.
Service manuals might be available on Ebay if you take a look.
Good luck.

Now we are on to something. After reading your reply I was able to google for it. Prior to your message I had no idea what the stuff was called. I found this link on another page. The red part is there, but I am assuming there is something that needs to go into it.

I might be hitting you up on this parts. I need to look at exactly what I have. Do you by chance have a picture available or the parts?

I attached some pictures of the shifting fork and shaft.
Do you have these parts?

So after getting home and looking I found the piece that looks like it goes into the dog clutch. It fit in the groove anyway (as shown in picture 1).

I put a piece of threaded rod into the whole that I assume a shaft is supposed to go. If I keep tension on it I can shift the left and right and it will move in and out. I also have a picture of the dog clutch attached in case it is needed. My lathe is a 1968 hlv-h. Would you know if there are any other pieces that I should be looking for other than the shaft that I am missing?

Well, it looks like I replied just after you did. It appears that I have found the fork, but cannot locate the shaft. Are those the only two parts that are needed? Is the shaft by chance threaded on one end? Could you either let me know that information (threading and size) or possible talk offline to purchase the extra part if it is available.

Thank you!

How do I get to the Yahoo Hardinge group?

Paul,

Thank you very much for both of your help. I spoke with the gentleman that I received the lathe from. We spent a couple of hours drinking beer and looking through boxes of misc tooling and parts. We managed to find the shaft and I have installed and tested. Everything is working great.

Jim,

I am very much enjoying all of the documentation that you have provided for my lathe!!


I just wanted everyone to see my response to these two standup guys.....

This is not meant to be offensive, don't take it that way......that is a pretty crummy looking gear box....and I would bet tommorrows pay that it is very noisy....maybe it was taken apart before you got it .........so no one would use it..

you may be looking for more than the shaft....you may be looking for a whole gearbox....if you price it out at Hardinge ....you better remortgage your home.

I'm a member of the Yahoo group, but if you really want quality manuals, I always go with this guy.

http://www.ozarkwoodworker.com/manuals/hardinge/

His prices seem pretty reasonable, and he carries a lot of hard to find manuals. All the manuals I've ever received from him are in great condition.
