For those with repairable Bellett water pumps (needing impeller , shafts, bearing , seals etc. ) it may pay to contact James Florrimell at Auto Surplus in Mitcham, Melbourne Vic. . EMail - firstname.lastname@example.org
. James had a Trade Stand at the Victorian Classic Japan Display at Como Park and in further contact with him he has indicated that he should be able to supply the above repair parts. I found James very helpful and professional in his field.
Well worth contacting if you have some supply problems.
