Honda P/N 19200-MZ1-315 94-95 CB1000 Water Pump Overhauled RARE p/n 19200-MZ1-315, With Front Cover P/N 19221-MZ1-305.  This pump is obsolete from Honda.  All new parts except housing and impeller. The pump assembly has also been Alodine'd (light gold tint) which is an aircraft grade anti-corrosion coating that bonds with the aluminum surface.  This is also an excellent prep if you choose to paint.  This auction is for the outright purchase of this overhauled pump and required O-rings,  exchange is necessary. Priority shipping in the lower 48 only on overhauled pumps, email me for other locations.

NOTE: This pump has a pit on the hose connection, see photo,  and will not affect operation, it is behind where the hose clamp will be.  I suggest that you fill with JB Weld, which works well.

OEM style bearing with precision laser cut slot for oil pump tang, ceramic/carbon seal set, lip seal and O-rings, see photo of parts.   Please read my life time warranty below.

I have spent 3+ years working on this and have been able to find a company to manufacture the correct bearing, including the U slot cut precisely with a laser.  It is not machined or ground out with unknown dimensions, it is very accurately centered and fits with the same tolerances as Honda has used. 

I have included one of my test pumps in the photos.  Like my test pump, all overhauled pumps will be cleaned and micro bead blasted, assembled with care and then tested for leaks, like the photo.  I run them for 20 to 30 minutes and verify there are NO leaks.  

If you have a press and are able, I also sell a parts kit that will include a specially made tool and detailed instructions.  Due to the unknown and the possibility for damage etc. there is no warranty on the kit.  I inspect every kit before shipping.

LIFETIME WARRANTY: The advantage of having me rebuild your pump, or purchasing an assembled pump, is that I will give you a lifetime warranty.  If the pump ever leaks at the weep hole, I will repair and ship back to you at no charge.  This does NOT cover the cost of removing the pump, shipping back to me or ANY misc. damage.  Do remember it is up to you to maintain the cooling system in very good working order and always use distilled water when mixing with antifreeze.

Thanks, stay cool......
