Santinelli 7070 Bearing replacement

[knsasctyshufl]

After doing a search for repairing/replacing the bearing in the quill of the 7070, I wasn't able to find much so I thought I would post what trouble I am having. Basically when the grinding wheel starts to spin, I'm getting a terrible noise. After disassembling, how do I finish getting the quill off the machine and how do I get the bearing off of the quill? See pics below. Thanks!

I'm not an expert on these machines by any stretch of the imagination, however, looking at pic 2, how is the spindle mounted to the edger chassis? Check for lugs or tiedowns that hold the spindle in place. Remove all of those, and the spindle SHOULD slide to the right. There's probably a seal (the black ring that appears in pics 1 and 3), that will have to be replaced, this keeps water from entering the inside of the edger.

Once you have the spindle itself out, take it to a professional machine shop and have them strip and change the bearings for you. The bearings will most likely have to be pressed out, and that is something that is not for the faint of heart or equipment challenged folks.

I have the same problem with my LE 7070. How were you able to remove or replace the spindle? Was it complicated to remove the bearing and do you have any recommendations or advice on how to proceed with the work? Thanks very much for your help.

Call VSI in Florida. They supply parts and refurbish 7070s.

I contacted them to see if they had parts for the LE 7070 and they told me that they weren't a parts company. Their response was that they only sold compete edgers and only serviced what they sold. I'm trying to hunt down a service manual for the LE 7070 to see how the spindle can be removed and if it can be repaired. Apparently, there are different types of spindles and pulleys for this edger, so it would probably be best to keep the original parts and get them repaired.

Thanks for your help and suggestion.

I can not make any specific suggestions, but, as Mike suggested you might want to take the whole machine to a local machine shop for repair. Unless you know what you are doing you could easily damage proprietary parts (expensive castings) but the bearings and seals are off the shelf stuff.

Check your customer records and see if you have a customer who is a machinist. This is an ideal opportunity for a workman's exchange. You fixa da edger - I maka you some nice glasses.

I initially contacted Santinelli's tech support for advice on my edger. They said that the possible problems were the drive motor or the belt connecting the motor to the spindle. I've been able to confirm that the motor runs well but the belt slows to a stop when the lens meets the roughing wheel. I adjusted the tension on the belt but it continued to stop during the roughing cycle. I spoke with a serviceman who also sales reconditioned edgers. He said that the problem was with the spindle BUT it's a bear taking it out. His suggestion was that if I could remove the spindle, he has a machinist who could repair it for $700.00. I wanted to see if someone on this board could advise me on how to get the spindle out and does it take $700.00 to get it repaired.

Your suggestion is right on target. I just need to know how to get the spindle out and how to get it repaired.

Thanks for your input.

Thanks for the lead. I checked the auction item and found that the seller removed the item from auction in Feb 2015. It would have been nice to have it.

Sorry that didn't work out. I've gotten parts there, but I also bought my edger there, so that must be why. I was unaware of the restriction.

It's a learning process for me, too. I'm finding that everyone on this forum has been extremely helpful with their suggestions and information. I'm pretty confident that I can get my edger repaired using the help and advice offered on this thread.
