VPI RCM 17 F trouble, very urgent NEED HELP......

Thanks for the update. Did it really take nearly 3 months?

Najferi,

I had a similar problem with my 16.5 after only a few hours of use. I thought the gears in the motor were stripped, they're only plastic. While the machine was under warranty, it was too much trouble to return it.

After opening the machine up, I noticed the motor was a Dayton as supplied by WW Grainger. No model # was visable. I called VPI and spoke to harry's wife who gave the motor #. I ordered it from Grainger only to find that it was the wrong motor. It was the one used in the Typhoon. I decided to remove the motor and mounting plate from the 16.5. After doing so, I found the problem.

There are 2 set screws locking the table plate to the motor shaft. There is a flat ground on the motor shaft onto which one set screw must be tightened. The 2nd screw locks down on the round. Whoever fastened down both screws didn't make sure ONE was on the flat of the shaft. So much for the American manufacturing prosesses.

My machine now has plenty of table power and I have two spare VPI motors; anybody need one?

Well as for 3 months no it just took 1 month to get every thing done. I was in the process of moving so could not send the machine out to VPI.

So Ken you have 2 machines out of which one is for the typhoon or both for the 16.5.

Njaferi,

I have one for each. The first Grainger part number was for the Typhoon. It ran $63. and as soon as I compared it to the one in the 16.5, I knew she gave me the wrong motor number. After getting the correct number I reordered from Grainger. While I was removing the motor I noticed the score marks on the motor shaft. Checking out both set screws I noticed they were both screwed in at the same dimension. Furthermore, there was no mark on the flat of the motor , telling me that both screws were locked down on the round. I affixed the platter bearing properly, remounted the original motor and everything was fine. I now have 2 new VPI motors that I'm too lazy to return to Grainger. The 16.5 motor ran $44.

Since I pre wash on the machine using more pressure than I should, I figure it's only a matter of time before I'll need a motor replacement.

Hello, Would you offhand know the part number for the 16.5? Would be good to know as a reference. Thank you, Mark
