BLUF: Do not reattach the on board oil exchanger (OBOE) on Stryker vehicles for any reason.
Some mechanics have recently reattached the on board oil exchangers (OBOE) on their unit’s Strykers. However, those OBOEs were disabled for a reason.
PM Stryker Brigade Combat Team (PM SBCT) sent out TACOM Maintenance Action Message 14-051 back in 2014 instructing units to disable the OBOE on all Stryker vehicles. The operator manuals were also updated to remove the requirement for operators to check OBOE oil levels during PMCS.
Some well-meaning mechanics have recently reattached the OBOE on their unit’s Strykers, even ordering parts to do so. This is unnecessary as the decision to disable the OBOE was made to reduce unit maintenance costs and the maintenance burden on Soldiers.
