General Pump GP Kit K28 Packing Assembly (GP)

Worked great no problem

This is not an OEM kit. They look used and refurbished.

fit like a glove

This kit is made in China, not Italy as described. It is definitely NOT the OEM General Pump kit which comes in General Pump packaging.

great product

This kit is a good value on Amazon - the price is significantly lower price than we paid to Landa Industries for same kit. *** Straightforward replacement *** These pumps need qty three (3) kits (one for each of the three pistons). Very slight design differences in the kit parts components, between the components on our older T47 S 20mm x 16mm pump, but external dimensions are identical. We're assuming the differences are likely design improvements. Tip - lacking the special GP factory retainer ring retractor tool, we used an arm taken from from a gear puller tool, to gently pry out the three large #43* retainer rings that were firmly seated in the pump head. The pump head is brass so be careful not to scratch/damage its surfaces. Another tip - used a large needle-nose plier to rotate/loosen the #46* intermediate ring while removing it. Be sure to put some never-seize on the eight head bolt threads. Mgf recommends using silicon assembly lube. Torque spec on the eight bolts for the pump head is 22.1 ft lbs./29.9 N-M. *Part numbers referenced from General Pump T47 S pump spec sheet.
