Hello , as you can see from part book , there is only a bushing and sharft and the packing in the pump , some have turned up new sharft and bushing when they became to to pitted to stop water bypass when new packing is fitted

use marine grease its better washout resistant. and never use graphite type packing with stainless shafts it attacks the stainless. fine on steel though.
I have replaced many brass shafts out of bulldozer water pumps with stainless and never had a problem. They use graphite impregnated rope packing.
The sugar mill where I worked used graphite impregnated rope packing on several centrifigal pumps all of which had stainless shafts.
If I had the option on packing, what would an alternative to graphite impregnated be? Just regular hemp soaked in plumber's green grease? That's what I used when plumbing although the components were all brass in that scenario
Leather shoestring, lol
The last water pump packing that I got from Ca for our D7 3t was a white teflon type square packing
The Teflon type seal for a 3T was also utilized for a 30 water pump. JM

i was told that by a marine engineer maybe its when combined with salt water it attacks/wears it. you can get plain white packing that isnt graphite treated. yet dad assembled many borehole pumps with graphite grease on the connecting collars and guide buckets. yet i trust the opinion of the bloke who told me and he should know over 30yrs at sea all over the pacific ocean

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
