REPAIR INSTRUCTIONS - HR2527A/HR3025/HR3030

NOTE: Always take time to lubricate all metal and nonmetal parts with a light film of oil before reassembly. This step will ensure proper fit, at the same time protecting the pump's nonmetal parts (elastomers) from cutting and scoring.

7.Tap the back of the manifold (28) with a rubber mallet to dislodge, and slide off the plungers (10). Take note of the position of the discharge port so as to place the port in the same position during reassembly.

9.Remove the valve cones (19A), valve springs (18), v-sleeves (20) and pressure rings (22). Inspect for wear and replace as necessary. Remove the spacer ring (16) and flinger (56) from the plungers (10).

11.Reassemble in reverse order. Fill the crankcase until the proper amount of oil (see specifications page 3). The pump is now ready for operation.

10.If the crankcase oil seals (15) are to be replaced, they can be removed by prying loose with a small screwdriver. Take care not to make contact with the plunger (10) and pry out the oil seals from their housing.
