Part 2 - Fadal VH-65 Cleaning, Inspection, Parts

Basically I cleaned the whole thing up - Scotchbrite, solvent and elbow grease. I found several setscrews that were sealed with silicone seal at various locations. I also noted that some of the mounting screw holes where through holes and could leak, those had silicone on them too. 
Since my application for this would be hobby use, I wanted to spend as little as possible. I knew I was in for seals, but wanted to reuse everything else. I found the main bearings (BRG-0037/BRG-038 and BRG-0035/BRG-0036) where less than wonderful. The races had damage from what looked like corrosion, but I wasn’t going to replace them. I decided to simply polish them with some crocus cloth.

Once I cleaned up the rollers etc. they seemed to spin smoothly enough for me. Other than cost - I also had no idea how to remove the bearing located in the chuck. What kind of puller do you use for that? I also didn’t look forward to removing the races as that would have meant pressing them out and in I’m sure!

How do you get that bearing out?

Everything else looks OK

Parts List

Next on to ordering parts - A few things to note. The parts diagrams I found for this showed only two of the HDW-0176, but my rotary needed 3. Also there are 4 1/4″ o-rings that seal the motor mount screws not listed in the diagram, their part number is HDW-0149. Also note there are 3 HDW-0162 o-rings for the motor cover to motor plate seal and the same o-rings are used to seal the end plates - so you need 5 total. I found the large lip seal (HDW-0224) on eBay for $25. Also the o-rings are standard so any decent parts house can probably get em. I found all these at FadalCNC.com aka CNCPros.com. Although prompt, they sent me several incorrect o-rings, which required another shipment. They were very responsive about fixing it and shipped the replacements overnight, no charge!
You’ll need gear oil to refill it. I didn’t realize I could order a gallon from CNCPros, so ended up getting 5 gallons off eBay. The original lube was spec’ed as MOBILGEAR 626 - LUBRICATION OIL ISO VG 68. Apparently Mobil 626 has been superseded by Mobil 600 XP 68. 3 Quarts will run you $15 from CNCPros - Rotary Gear Oil.
