Mauser 98k - Model M48
somewhat difficult (it requires some strength in your hands and you
are dealing with a very powerful firing pin spring, so pay careful at-
tention).
a. Check the position of the safety lever. It should be in the vertical
(upright) position. If it isn’t, put the bolt back in the rifle and
close it. Swing the safety lever up to the vertical position. Then
remove the bolt from the rifle and proceed.
b. Separate the firing pin assembly from the bolt body as follows.
Observe the small spring loaded plunger on the rear of the bolt
opposite the bolt handle. It is the Bolt Sleeve Lock Plunger.
Grasp the bolt in your left hand and with your left thumb, push in
the plunger. With your right hand, grasp and turn the whole rear
assembly counter clockwise. After one or two complete turns, the
rear assembly will turn easily without pressure on the locking
plunger. Unscrew the assembly and lift the firing pin assembly
out of the bolt body. You will likely find it covered with protec-
tive grease, which would likely cause a failure to fire. Soak both
the entire empty bolt body and the firing pin assembly in solvent.
c. Notice that the bolt body has two gas vents in the bottom of the
bolt body. These serve two purposes. First, they serve as the pri-
mary gas escape holes in case of a cartridge failure and second,
they are two lubrication ports giving you access to the whole bolt
internally because you won’t want to take it apart very often.
d. Clean the bolt body:
i. Swab the interior of the bolt body. Make sure there is no
dried grease left inside.
