For the first time the log indicates some of the steps taken to do a major overhaul of a manual pump.
This turns out to be a two day job It can't be said to be a rebuild but it is easy to see how other components could have been replaced.

All the materials would have probably been purchased locally and painting and sign writing would have completed the job.
But note that there is no detail of the purchase of the materials it could of course have been to hand
Maybe the captains expense log will contain details I have yet to research this document
