Our NEW replacement water pumps are to original specifications by leading OE manufacturers and include fitting gasket..
KUBOTAMAN TOP TIPS
Water pump failures may be attributed to any of the following:
Bearing failure (noisy, caused by over-tightening of fan belt)
Mechanical seal failure (leaking)
Poor flow rate causing engine overheating (Impeller corrosion due to improper water treatment)
In the majority of cases, the most economic option is to replace the entire pump. However, repair kits are available for a few engine types (see below).
WATER PUMP GASKETS
All our gaskets are manufactured specifically for Kubotaman (all 'soft cut' gaskets are made in-house on our own laser cutter). They are the result of 20 years experience of repairing and remanufacturing these engines. Our sets are complete and comprehensive. Unlike others sets on the market, we pack everything you need to complete your build, including alternatives where necessary.
THERMOSTATS WITH GASKETS

KUBOTAMAN TOP TIPS
Thermostat failures can be diagnosed by any of the following symptoms::
Overheating (thermostat sticking in closed position)
Overcooling (thermostat sticking in open or partially open position)
Erratic overheating and overcooling (thermostat sticking randomly in position)
In the majority of cases the most economic option is to replace the thermostat.
WATER PUMP REPAIR KITS
New replacement parts for your own Kubota Water Pump; Gaskets, Bearings and Seals (Mechanical, Gland, Carbon)
For a more economic solution, repair kits are available for a small range of water pumps. The repair kit consists of the bearing, the carbon seal and the gasket. To replace the bearing and seal requires the technician to remove the impeller and press the old components out of the housing. When installing the impeller back on the shaft it is important to set the clearance between the impeller and pump body to the correct value. It is best to measure this clearance before removing the impeller in the first place.
