Davey - Service Motor Kit for Silensor SLL400E (Old Generation, No Splined Groove) with Shaft & Impeller - KSLL400

Davey – Service Motor Kit for Silensor SLL400E (Old Generation, No Splined Groove) with Shaft & Impeller

This is the genuine Davey service motor kit (SLL400E) designed specifically for the original “old generation” Davey Silensor SLL400E pool pump — the variant without a splined shaft groove. The complete kit is supplied with a new shaft and updated impeller, ensuring full compatibility when upgrading the motor assembly on these earlier pump variants. It is the correct replacement solution when the motor of an SLL400E (“-0” suffix model) has failed, lost efficiency, or requires a full motor overhaul.

Compatibiliteit

This kit fits the Davey Silensor SLL400E in its original “old generation” configuration (model suffix “-0”), identifiable by the absence of a splined groove on the shaft. It is not intended for current-generation SLL400E pumps with a splined shaft, nor for three-phase SLL4003F variants. The SLL400E is a single-phase, 220/240 V / 50 Hz pump rated at 1760 W (2.4 hp), and this CE-rated motor kit is distributed exclusively through Davey Europe for the European market. Always verify your pump’s generation before ordering.

What’s Included & Why the Shaft and Impeller Matter

Because the internal geometry of the old-generation “-0” motor differs from the current design, Davey specifies that when the motor is replaced on these pumps, the impeller must simultaneously be updated to the new style. Accordingly, this kit is delivered complete with the new-specification shaft and impeller — ensuring correct hydraulic balance, proper clearances, and reliable long-term operation. The service motor assembly covers all primary internal motor components required for a full motor replacement.

Installatie

Replacement of the service motor is a workshop-level procedure. Davey Silensor service spanners (part numbers 13810SP and 13810-1SP) are required to remove the case nuts, along with bearing press tools. Installation should be carried out by a qualified pool equipment technician following Davey’s official Silensor servicing instructions. Ensure the pump is fully isolated from the power supply before commencing any work.
