Caterpillar repair kits for JMP sea water pumps are available in different configurations for maintenance and overhaul operations.
Scandiesel supplies JMP repair kits for sea water pumps compatible with Caterpillar applications.
This page includes the main repair kits available for different pump models, including complete repair kits, minor repair kits and seal kits, where applicable.
The technical illustrations show the components included in each individual kit and are intended to make identification of the supplied parts easier. To confirm correct compatibility, we always recommend checking the pump model, engine model and, if available, the original spare part number.
Sea Water Pump JPR-CT0150
Repair kit for Caterpillar JPR-CT0150 sea water pump. Complete kit JSK0168 and minor kit JSM0168 available. Contact us to verify compatibility.
Available Kit:
- JSK0168 – Major Kit
- JSM0168 – Minor Kit
Important technical note
The JSK0168 and JSM0168 kits are intended for servicing the JMP Marine JPR-CT0150 pump.
When using JMP components for service work on original/OEM Caterpillar pumps, special attention must be paid to the mechanical seal: for original/OEM pumps, the OEM CAT mechanical seal must be used, not the JMP mechanical seal MCSSET0008.
The JMP mechanical seal MCSSET0008 is intended exclusively for the JMP Marine JPR-CT0150 pump.
This difference is due to internal modifications introduced to improve the durability, quality and performance of the JMP pump.

Sea Water Pump JPR-CT1800R
Repair kit for Caterpillar JPR-CT1800R sea water pump. Complete kit JSK0139 and minor kit JSM0139 available. Contact us to verify compatibility.
Available Kit:
- JSK0139 – Complete Kit
- JSM0139 – Minor Kit
Important technical note
The G18082X model uses the Sherwood 18000 impeller (#8350-01K), with a 14-spline drive insert.
The G2902X model uses the Sherwood 29000 impeller (#8359-01K), with a 10-spline drive insert.
The complete pump assembly JPR-CT1800R can be used to replace the G18082X. However, as shown, it is not possible to use the internal components of the JPR-CT1800R replacement pump — namely kits JSK0139 and JSM0139 — to service the older G18082X pump version.
If this older G18082X model needs to be serviced, the Minor Kit #JSM0139 can be used, but the #8350-01K impeller must also be purchased separately, as this is the impeller with the 14-spline drive insert.
The components included in kits JSK0139 and JSM0139 can be used to service the JPR-CT1800R pump and Sherwood models G2902X and G2906X.
Both Sherwood models use the same internal components; therefore, the Major Kit #JSK0139 and Minor Kit #JSM0139 can be used for both pump models.
However, the drive gears — which are not included in either the minor kit or the major kit — are not the same.
It is important to note that the G2902X, corresponding to the JMP Marine JPR-CT1800R pump, uses drive gear p/n 22789, with 40 teeth.
For this reason, the complete JPR-CT1800R pump assembly cannot be used as a direct replacement for the G2906X.
To use the JPR-CT1800R pump as a replacement for the G2906X, the drive gear must be removed from the new pump and the existing 36-tooth drive gear from the original G2906X pump must be installed.

Available Kit:

Important technical note
This note does not apply when the major and minor kits are used to service a JMP Marine JPR-CT3054 branded pump; this note only applies when servicing an original/OEM pump internally.
The JMP spare parts kits listed below can also be used to repair and service original/OEM pumps, but the CAT mechanical seal p/n 4204328 must be used instead of the JMP mechanical seal MCSSET0008.
The mechanical seal MCSSET0008 is intended exclusively for the JMP Marine JPR-CT3054 branded pump.
Why was the mechanical seal changed?
To provide a longer-lasting mechanical seal, improving product durability and performance.

Sea Water Pump JPR-S7632
Repair kit for Caterpillar JPR-S7632 sea water pump. Complete kit JSK0072 and Minor kit JSM0002 available. Contact us to verify compatibility.
Available Kits;
- JSK0072 – Complete Kit
- JSM0002 – Minor Kit
Important technical note
The Sherwood 27000 impeller must not be used on JMP Marine JPR-S series pumps, even if the dimensions appear to be compatible.
The Sherwood version is manufactured with a thicker threaded insert, which can bottom out against the end of the shaft and prevent the impeller from seating correctly inside the pump body.
Using this impeller may cause an incorrect clearance with the pump cover, resulting in overheating, damage or melting of the impeller.
For JMP Marine JPR-S series pumps, only the JMP #7608K impeller must be used.
Furthermore, the internal components are not compatible with those of the OEM pumps.
