Parts Information

ATTENTION: PARTS MANAGER

This Parts Bulletin provides you with the information you will need to obtain the parts to repair the reed valve subassembly. Complete campaign instructions will be sent to you on January 2.

The vast majority of vehicles will only require replacement of the reed valve subassembly, part number 28821-21040. You may order these in 10-packs only, with a 5-pack limit, from your facing PDC. Supplies will be limited, and orders above 50 pcs. will not be filled without review by the HMA PDC Expeditor.

HMA is providing you with two initial shipments of these assemblies which will arrive about December 30, and the second week of January. Order quantity is based on the number of vehicles in your immediate area.

For the very few vehicles that will require replacement of the ACV assembly, you may order the following two part numbers:

28822-21030 (ACV Assy, 2 vacuum line type: 1986-1987 Federal Specification).
Available in single packs, with 5 PC. maximum order.

28822-21040 (ACV Assy, 1 vacuum line type: 1988-1989 Federal Spec. and all Calif. Specification).
Available in 10-packs, with 10 PC. (1 pack) maximum order.

These should only be ordered on an as-needed basis and all replaced parts will be audited by HMA to verify that replacement was necessary.

Please note that the Reed Valve Subassembly and ACV Assemblies are not In the parts catalog or microfiche.

Any additional parts needed to complete vehicle repairs may be ordered through the parts catalog; however, the need for additional parts is expected to be very low and the warranty claims will be 100% audited by HMA along with 100% return of all replaced parts for inspection by HMA.

Please note that demand for this campaign is expected to be very light until the first owner mailings are made on January 20.

Please contact the Parts Expeditor at your facing PDC if you have any questions. Thank you for your cooperation.
