There always seems to be a lot of confusion and questions on ID’ing power steering pumps and what kit to use because Rock Auto has a horrible listing on these parts, they refer to chrysler pumps, Saginaw pumps, But NOT a TRW pump. The following info should help the TRW owners on this site. Would be cool to have others add there pumps ( Federal, Saginaw) with part numbers, tools needed and such.
I’ll start this one off! Because I just got done resealing two different styles of TRW pumps. The “Small” TRW pump is the pump with the plain shaft, no hole, no hex. The Edelmann kit part number is 7897. The “Large” TRW pump with the hex shaft ( Does Not have internal threads to reinstall pulley) uses Edelmann kit number 7898. You can buy the kits from Rock Auto or Amazon.
Note...don’t buy the lisle tool part number 39000, it won’t fit the pulley hub to remove the pulley. I ended up buying an OTC tool. Worked great.
You do need a press to get each of these pulleys back on. None of these shafts are threaded for the tool to reinstall the pulley.
Hope it helps....
