KB-2 water pump rebuild
![Post Post](./styles/OldIHC/imageset/icon_post_target.gif)
Sooo I've started on the water pump rebuild on the KB-2. The first step was to remove the bearing snap ring from behind the fan flange, next the impeller which came off (with a hydraulic press) fairly easily. The shop manual shows it being removed with an arbor press. That ain't gonna happen! I have a 20 ton arbor press trust me!. Once the impeller is off the bearing and flange are pressed out of the water pump housing (Remove the snap ring before doing this) .
Next came the flange (fan). YA! That wasn't moving at all with a 40 ton hydraulic press and heat! Over to the lathe to drill a 1/2 inch hole through the end of the shaft. The shaft is 5/8 inch.

Even with all that metal removed it was still tough going but it did press off.
Once apart it was cleaned and blasted.

I have a good source for the W/pump bearing a Federal bearing No. FB 5144 and a seal so that should be OK.
Here is the casting number and a symbol (upper right) I'm trying to decipher, a "T" "B". Any ideas on this symbol?
