Yes, in the three different printed manual versions that I have, 1984, 1986, and 1997, two of the three show the transposed number (884283 vs 884823) in the pictorial text, however on the page listing all the service tools all three versions show the correct number.(884823)
It might be noted that there are two tools listed for installing the injector copper:
- 884557- drift for installing the copper sleeve in the head
- 884823- flaring tool for swedging the copper into the head
According to the online store “Marine Parts
Express” the swedging tool does not show up discontinued.
