Bulletin No. SB-847 Generators - d.c.
SUBJECT: A cross reference of Johnson and Auto-Lite 12 volt generator part numbers. 35 h.p. models RJE(L)-19 & 19M; RDE(L)-19 thru 19C; RDS(L)-20; RDS(L)-21 & 21B; 40 h.p. models RDS(L)-22 thru 23; 50 h.p. models V4S(L)-10 thru 11B; 75 h.p. models V4S(L)-12 thru-13C.
The following cross reference of detail service parts from Auto-Lite to Johnson, and vice-versa, is used to determine part numbers in the same manner as parts catalogs are used. Simply locate the part in the exploded illustration contained on page 2, note the detail photo number, and refer to the same number on the following pages for the desired Johnson and corresponding Auto-Lite part numbers. Columnar headings are self-explanatory and should present no problem in understanding them.
In all instances of determining detail part numbers, it will be found advantageous and timesaving to predetermine the Auto-Lite model number in order that the correct detail part may be accurately chosen. The Auto-Lite model numbers are stamped on the frame and can be readily obtained from it.
Prices of the detail Johnson parts, or superseding part numbers, will be found in the extreme right hand column. All prices listed are current, but are subject to change without notice.
Except as otherwise indicated, dealers order all parts by the Johnson number only from your parts distributor. Do not order from the factory or the parts depot.
