Introduction

The Milwaukee Rotary Hammer 260520 D14A 2016 gasket may need replacement if the device is leaking oil, isn't hitting hard enough, or is stalling. Keep in mind that this guide calls for accessing the gear case assembly, so expect whatever is touching the device to get exposed to grease. Some of these steps also require a considerable amount of force from the user.

Gaskets are mechanical seals that protect joined surfaces under compression by padding the space between them.

Tools

Step 1

Remove the battery by sliding it from the base.

Step 2

Remove two 20.3 mm screws at the right side of the drill base using a Torx T3 screwdriver.

Step 3

Step 4

Remove four matte 24 mm screws on the crankcase at the rear cover of the drill (connecting the chuck to the handle) using a Torx T3 screwdriver.

Step 5

Remove two 24 mm screws on the housing cover beneath the ventilation slots. These screws point into the drill.

Step 6

Using a Torx T5 screwdriver bit, remove two 26.8 mm screws on each side of the drill housing cover, located beneath the ventilation slots. These screws point upwards.

Step 7

Gently pry apart the covers for the drill handle.

Step 8

Push down the locking sleeve at the head of the drill.

Step 9

With the sleeve pushed down, pry off the dust cap.

Step 10

Turn the drill so that it points downwards. Push in the ball support plate so that the 7 mm ball falls out.
The ball may fall out unexpectedly. Make sure you are attentive and have a clean workspace.
