Section 7 • Warranty and Parts
STEP 4. For defective motor or starter claims, if the mo-
tor or starter falls within the OEM's warranty time frame:
•
The motor or starter will need to be taken to a man-
ufacturer approved shop for diagnosis. Vilter™ can
help you locate motor shops in your area that are
manufacturer approved. The shop will diagnose the
root cause, submit a report to the OEM, and the mo-
tor OEM will make the determination of warranty
coverage.
•
If a warranty claim is approved, the OEM will either
have the motor or starter repaired by the motor
shop or send a new replacement motor to the site.
On-Site Service Support
If on site support is required, contact a Vilter S&W de-
partment representative to start this process.
Warranty does not cover labor or expenses.

A quote, a service rate sheet, and the service terms

Remanufactured Bare Shaft Single
Screw Compressor Process
These instructions are an overview of how the process

may arise prior to contacting customer service.
The process begins by contacting Vilter's Customer
Service Department. Vilter contact information can be
found on page iii.
• Request a "VSS/VSM Single Screw Compressor
Rebuild Form".
• Submit the Rebuild Form and a Purchase Order
(PO) for the inspection. A fee is required for the ini-
tial inspection and tear down report; contact Vilter
Customer Service representative for the latest fee.
• A Return Material Authorization (RMA) number will
be provided.
• Send the compressor to Vilter in the condition as
stated on the Rebuild Form (i.e. no oil in the compres-
sor). Charges may apply if conditions are not met.

• A report will be sent to you after the inspection has
been completed explaining what level of rebuild is
necessary along with the cost.
Inspection and rebuild times will vary, contact Vilter
Customer Service representative for further details.
• Submit a new PO for the amount that will be needed
for the rebuild. The inspection cost will be waived
upon receipt of the new PO. Make sure to provide
your "Ship to Address" and "Billing Address".
Explanation of Rebuild Levels
Level 1
Compressor is in good condition. Replace bearings, gas-
kets, shaft seal and O-rings. All hardware is intended to
be re-used (when possible). Parts are organized in part
kit form.
Level 2
Compressor is in good condition, but requires new gate
rotor blades. Replace all items in Level 1 plus new gate
rotor blades and bushings.
Level 3
Current Reman Compressor requires complete rebuild-
ing and re-conditioning to "as-new" condition. All the
components listed in Level 2 are replaced plus all hard-
ware, slide assemblies, pistons, and a main rotor (if dam-
aged) and/or gate rotor supports.
A Level 1 and Level 2 rebuild will include washing
the housing and repainting over the current paint.
A Level 3 rebuild will include blasting all the current
paint off before repainting.
