Jim Bird Posted January 26, 2017 Share Posted January 26, 2017 I recently had an oil leak from the 5 speed gearbox on my 16 valve TC. The main output shaft seal on the passenger side was allowing oil to leak past it. Rock Auto list both a National part #2003N (equivalent to Timken #2003N) and SKF part#15750 as replacements. NEITHER IS CORRECT. The National 2003N will fit into the transmission housing but it is made to fit a 1.417 inch diameter shaft while the output shafts on the Getrag 284 are 1.375 inch diameter. Needless to say it does not keep 5W30 oil inside the transmission. Ask me how I know! The SKF #15750 will not fit into the transmission housing as it is too large in both O.D. and I.D The correct seal is SKF # 13750. This may simply be a typo error as the SKF part numbers represent the shaft size that they fit--i.e. 1.575 and 1.375 inches respectively. Link to comment Share on other sites More sharing options...
Reaper1 Posted January 27, 2017 Share Posted January 27, 2017 Were you able to source the correct seal, and if so, where? Link to comment Share on other sites More sharing options...
Moparite Posted January 28, 2017 Share Posted January 28, 2017 You can look up any seal by just having the id and od sizes. http://www2.chicago-rawhide.com/popup_parts_lookup_457010.htm Link to comment Share on other sites More sharing options...
Jim Bird Posted January 28, 2017 Author Share Posted January 28, 2017 Sourced the correct seal from SKF Canada through a local transmission shop. Link to comment Share on other sites More sharing options...
Nile Posted January 29, 2017 Share Posted January 29, 2017 Any chance you could post the part numbers? Thanks - Nile Link to comment Share on other sites More sharing options...
