    Kashiyama raw water pump-gctid649173

    Fleet,

    After an exhaustive forum search about Kashiyama pumps I believe I have determined there is no way to lubricate these pumps. Mine are on my workbench where I have complete access to them. There is no zerk fitting that I'm able to see.

    Both are working fine but after 3 years I am changing out the impellers which appear to be in remarkably good condition. It's easier for me to remove the pumps than attempt an impeller change out while on the engine.

    Jim, I have the hino 110 , and need to replace the rawwater pump that broke while I was trying to remove the suction hose to clean out pieces of the empeller. Do you know if we have the same pumps, and is there more to removing the pump then just the two flang bolts.

      Kevin,

      I'm sorry I do not know if we have the same pumps. For comparison the pump I have has four hold down bolts. I can't imagine being able to break the pump while removing the water hoses as this pump is pretty stout. There are inlet/outlet hose fittings that bolt to the pump, maybe you mean these as they are thin wall brass or bronze?

        Thanks Jim, but are pumps are different. The 110's have 2 bolts mounting the the pump to the engine block and hose nipples for the inlet and outlet screwed into the pump housing.

          "There is no zerk fitting that I'm able to see."

          The grease fittings for the EH700 pumps are in the center of the housing between the pulley and the pump.

          This pic should make that clear if I can post it correctly. See #9.

            Smitty,

            I must have weird pumps as they do not have zerk fittings anywhere. Ironically, I see a boss in the top of the casting where they would/should go. The two pumps I have are on 1989 EH700's which, I believe, was the last year these engines were used on 3888's. I wonder if there was a design change to eliminate the zerks in later models?

              I have a 1988 3818 and the stbd engine has a Kashiyama port the original from Bayliner. I bought my boat in 1994 with these pumps. I assume the stbd was changed buy PO. I have never had a problem with the Kashiyama and there is no zerk.

              Smitty,

              Is the diagram you posted of the 1988 and before pumps rather than a Kashiyama which was used in 1989 boats? If it is a Kashiyama why have we had no problems?

                Richard,

                Are you saying the Kashiyama is an after market pump on your boat and the other pump(whatever it is) was the original? I suspect it's the other way around but I may have misunderstood your post.

                  Jim,

                  The Kashiyama is yellow on the stbd. The port is original engine blue. I believe the Kashiyama is the replacement. I see that your picture of the Kashiyama is blue, there must be some changing of pumps during manufacture of these boats?

                    Jim,

                    My 1989 3888 has the same pumps, both are original. Both of mine have the zerk fittings for grease in the bosses. In the factory manuals I have they talk about lubrication intervals (500 hours or once a year) and grease types. "Inject a good quality grease meeting MIL-G-10924B specifications at the grease fitting with a manually operated "gun" --avoid seal damage by stopping injection as soon as back pressure is felt. "

                    If the bearings are sealed, the grease fitting is not necessary, but if open bearings I would want some way to lubricate them.

                    I'll post a photo of mine when I get back from the boat today.

                    Interestingly, my coolant circulating pumps both have grease fittings as well.

                      Richard,

                      Interestingly enough underneath the blue paint on both of my pumps is yellow paint! The paint signatures suggest the pumps began life yellow and were overprinted the blue green once assembled on the engine. Perhaps the yellow is primer?

                      James,

                      Take a look at the attached pic. It appears Kashiyama made a design change somewhere along the end of the production run of pumps. I say this because my boat is an 89 but it has signatures of the 90 version, things like the fuel supply lines and valves that were apparently a 90's change. I suppose if the pump is sealed and not leaking it doesn't require greasing.......I hope! My circulation pumps do have the zerk fitting and I have greased them.

                        Same as my 1987 3870 with EH700 Hinos, I bought a spare pump off a 250 hp in a 45xx that had been re powered and it also has a zerk.

                          My original 1986 Kashiyama pumps had the zerk fittings.

                          I replaced one last year with a new Kashiyama, and it is sealed and does not have a zerk.

                          I rebuilt my old Kashiyama ( the one with the zerk fitting) and now carry it as a spare.

                            Jim,

                            My 1989 is I suspect a very early 1989 as it still has shore power connections near the cockpit. Serial number ends in F889.

                            Here is the picture of my pumps, both are identical. Interesting that when I removed them this winter to check impellers (both still perfect) there was yellow on the bottom. I thought it might have been a lubricant of some kind, never occurred to me it was the original paint.

                              I wonder if the overhaul parts remain available for these pumps? I'm not ready for t hat just yet.......it's just a matter of time I suppose.
