Roller carrier contacted injector pump housing...Help! - Troubleshooting - VWDiesel.net The IDI, TDI, and mTDI source.

• Roller carrier contacted injector pump housing...Help! by bonjovivw on 28 Dec, 2007 18:26
• I am rebuilding a TDI injector pump in a 1996 Passat TDI.
  
  I just noticed that the roller carrier has slightly contacted the pump housing
  
  Less than .001  but I can feel it
  
  Pump mainshaft does not appear to have any runout and bushings look good
  
  Wondering how this happened and if it is OK to use the housing.
  
  Any help would be appreciated.

• Our IDI had pretty bad wear on the housing and ran fine. It's not a sealing surface so it's not a big deal. Looks like someone had the pump rebuilt because that is only caused by bushing play.
