| Post subject: | new spark plugs |
I have: Three new AC type LS-87 spark plugs in their orginal tube - $5 each Dozens of new Champion type RHB-29N spark plugs in their original sealed plastic container - $10 each. Is there any market for used spark plugs? I have 5 gallon buckets of used plugs of many sizes and conditions. I have already tossed out the badly corroded ones. Let me know what you need and what you offer. I am learning that people value this stuff differently so please do not be offended if I say no. e-mail mrmotomontana for photos or look at http://s291.photobucket.com/albums/ll29 ... lbum_album Thanks Jim |

| Post subject: | AD on LS-87 plugs |
54-04-01 AC SPARK PLUG: Applies to All Engines Equipped With AC LA-87 Spark Plugs, Except Pratt and Whitney R-1830 Engines of 1,200 HP or Less and Wright R-1820 Engines of 1,200 HP or Less. Compliance required prior to March 1, 1954. A. In order to preclude possibilities of engine failure, when using AC LS-87 spark plugs in engines for which they are not approved, these spark plugs must be removed from all engines with the exceptions of the R-1820 having a T.O. rating of 1,200 h.p. or less and the R-1830 having a T.O. rating of 1,200 h.p. or less. B. On R-1820 and R-1830 engines of 1,200 h.p. or less, the LS-87 plug is limited to a maximum of 120 hours of service with no reconditioning permitted. Plugs having over 120 hours must be removed from service. This supersedes AD 49-26-02. I suppose there is a new plug that replaces the LS-87 for these engines?? Jim |
