Hi all,
I just planned how many ball bearings I really need and below is a list of my locomotives which I know or believe have DCM 3-pole or 5-pole motors. Please correct me if you know for sure that some of them are SFCM or LFCM motored. It seems like I need more bearings than 100 if i want to do this good modification for all of these. If all are DCM motors, then I need around 120 ball bearings!!
Steam locomotives• 37961, 37963 and 37967 BR 96 / Gt 2 x 4/4 (3 locos, 6 ball bearings)
• 3309/3709 and 33081 BR 85 (2 locos, 4 ball bearings)
• 2953x Digital and 37862-01 BR 86 (2 locos, 4 ball bearings)
• 29820 and 37953 BR 03 (2 locos, 4 ball bearings)
• 3084 DB, 3414 SNCF, 3416 ÖBB, 3417 NSB, 34157 SNCF, 34158 CFL, 37560 CFL BR 50 or BR 52 based locos (7 locos, 14 ball bearings)
• 3702 BR 53 (1 loco, 2 ball bearings)
• 3317, 3318/3618?, 29855, 29855, 29855, 29855, 33181, 33183, 37182, 37184, 37185 and 37186 S 3/6 or BR 18.4 type locos (12 locos, 24 ball bearings)
• 3313 DB, 3412 K.Wurt.St.E. and 3413 SNCF, 37131 SBB (4 locos, 8 ball bearings)
• 37884 BR 44 (1 loco, 2 ball bearings)
• 3107 SNCF, 3117 SNCF (2 locos, 4 ball bearings)
Electric locomotives:• 3039/29855 DB BR 110, 29855 DB E40 and 3740 DB BR 110 (3 locos, 6 ball bearings)
• 29151 DB BR 151 (1 loco, 2 ball bearings)
• 3038 SNCF and 3165 SNCF (2 locos, 4 ball bearings)
• 3166 ÖBB and 29680 SBB Ae 6/6 (2 locos, 4 ball bearings)
• 3367/3767 DB BR 118 (1 loco, 2 ball bearings)
• 3756.1 and 3756.2 SBB green Ce 6/8III Crocodiles (2 locos, 4 ball bearings)
• 4 DRG electric locos 37561 E60, 37661 E52, 37681 E18, 37196 E91.1 (4 locos, 8 ball bearings)
• 3157 DB BR 160 and 37060 K.Bay.Sts.B. EP 3/6 (2 locos, 4 ball bearings)
Diesel locomotives• 37650 V60 and digitalised 3028 BR 515 (2 locos, 4 ball bearings). Analog 3028 has not DCM motor.
• 2 BR 216 locos (2 locos, 4 ball bearings) 2 newer Digital from starter sets
• 29811 DB BR 221 (1 loco, 2 ball bearings)
• 3142 FS D236 (1 loco, 2 ball bearings)
Then I need also ball bearings for 3681 DB BR 221 and 37591 SBB Ae 8/14 in the future. I have a 3021 DB V200, 3022 DB E94 and 3134 CFL Nohab all converted to digital with 60904? kit so they need ball bearings too at least on the motor shield side. I just opened my converted 3021 and it has different motor block as the original motor was LFCM. Same in 3022 too, but 3134 has newer "Great Northern" Nohab technic and I think it will need to ball bearings. I will not modify motor blocks at this stage. I will only remove the bushes where there is one and replace them with ball bearings.
Total need of ball bearings = Around 120 !!!!What I have done so far for this project is I have drilled one motor shield by electric hand drilling machine. It went ok. First I drilled the original 1.5 mm hole to 2.0 mm, but then I just drilled it to 4.0 mm. I tested with that 4.0 mm drill bit other end that it became ok for hole tightness. I managed to drill that hole in the very center without any extra equipments, but it may be only my good luck that time

. I will order ball bearings soon. I will also test to some loco(s) ceramic high quality ball bearings to see if there is any difference or not. Maybe I buy 10 of those, so I install them into my Mallet locos 37961, 37963 and 37967 + two Crocodiles 3756.1 and 3756.2.
Cheers,
Janne

| Reason: Edited the loco list to have DCM motored locos only. Ball bearing need 134 => 120
