Determining shim thickness for Bosch injection pump replacement on BFM 1012 in case of service. Standard dimensions L 0 = 119 mm The old injection pump with shim is not required for such purpose. Example: The injection pump of cylinder 3 is to be replaced on a BFM 1012 engine. Procedure: Read off EP code for cylinder 3 from nameplate under column „EP“, e.g. 183. (Reading sequence: line 1=cyl.1, line 2 = cyl.2, etc. Mot. - Typ Code Mot. - Nr. kW(G) red. EP K 0122 3237 1 kW(G) kW(S) 1/min ) ° kW(S) red. E kW(W) °C m DEUTZ AG MADE IN GERMANY Take corrected injection pump installation dimension (E K ) from table 4 according to EP code, e.g. 122.05 mm.
Tabelle 4 Take code for injection pump length (A) from new injection pump, e.g. 22. Take standard dimension of injection pump (L o ) from table 1, e.g. 119 mm. Determine theoretical shim thickness (T s ). T s = E K - (L o + A/100) T s = 122.05 mm - (119 mm + 22/100 mm) T s = 2.83 mm Select shim thickness (S s ) according to table 2.
T s 2.83 mm = S s 2.8 mm 1.00.15.1 18 3 E K (mm) EP code E K (mm) EP code E K (mm) EP code E K (mm) EP code E K (mm) EP code 120.0 120.025 120.05 120.075 120.6 120.625 120.65 120.675 121.2 121.225 121.25 121.275 149 150 151 152 121.8 121.825 121.85 121.875 173 174 175 176 122.4 122.425 122.45 122.475 197 198 199 200 120.1 120.125 120.15 120.175 120.7 120.725 120.75 120.775 131 132 121.3 121.325 121.35 121.375 153 154 155 156 121.9 121.925 121.95 121.975 177 178 179 180 122.5 122.525 122.55 122.575 201 202 203 204 120.2 120.225 120.25 120.275 120.8 120.825 120.85 120.875 133 134 135 136 121.4 121.425 121.45 121.475 157 158 159 160 122.0 122.025 122.05 122.075 181 182 183 184 122.6 122.625 122.65 122.675 205 206 207 208 120.3 120.325 120.35 120.375 120.9 120.925 120.95 120.975 137 138 139 140 121.5 121.525 121.55 121.575 161 162 163 164 122.1 122.125 122.15 122.175 185 186 187 188 122.7 122.725 122.75 122.775 209 210 211 212 120.4 120.425 120.45 120.475 121.0 121.025 121.05 121.075 141 142 143 144 121.6 121.625 121.65 121.675 165 166 167 168 122.2 122.225 122.25 122.275 189 190 191 192 122.8 122.825 122.85 122.875 213 214 215 120.5 120.525 120.55 120.575 121.1 121.125 121.15 121.175 145 146 147 148 121.7 121.725 121.75 121.775 169 170 171 172 122.3 122.325 122.35 122.375 193 194 195 196 122.9 122.925 122.95 112.975 122.05 183
