Hi,
Finally got the spindle motor and cutterhead turning on my VN22L for the first time today. I had previously removed the cutterhead and cleaned out the grease and old oil (submerged the entire cutterhead in diesel for a few weeks).
I did not pull the spindle assembly apart, other than cleaning out the rear bearing cap and removing the front bearing cap as far as it will come, to allow washing out the bearings.
The ram gears themselves were similarly filled with diesel for a month or so run slowly, then drained.
Cutterhead bearings greased and both cutterhead and ram filled with ISO68 oil.
Now, I'm getting a fair bit of rear bearing noise from the cutterhead, and from the frontmost shaft in the ram (which drives the ram), in the top two speeds. The front spindle bearing isn't noisy.
The noise is quite a bit less when running the spindle in reverse. Which suggests to me perhaps this is just normal gear wear?
The cutterhead on mine is a more modern sort, NMTB50.
Thanks,
Phil
