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.
1. A quote, a service rate sheet, and the service terms
and conditions will be provided.
2. Submit a PO.
3. Schedule the service visit.
Remanufactured HPLD Bare Shaft
Single Screw Compressor Process
These instructions are an overview of how the process
works when a bare shaft compressor is in need of being
remanufactured. This is to help clear any questions that
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 an “HPLD 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.
NOTE
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
gaterotor blades. Replace all items in Level 1 plus new
gaterotor blades and bushings.
Level 3 - Current Reman Compressor requires complete
rebuilding and re-conditioning to “as-new” condition.
All the components listed in Level 2 are replaced plus all
hardware, slide assemblies, pistons, and a main rotor (if
damaged) and/or gaterotor supports.
NOTE
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.
