Olympus BH2-5RE Démontage, nettoyage et remontage complets

Clean Grease from the Various Components

Use a suitable solvent (e.g., acetone) to thoroughly

clean all the old grease from the stationary base,

revolving turret, threaded retaining ring, perimeter

bearing balls, center-pivot ball, mechanical detent stop,

pivot-adjustment screw, and the slotted lock ring, in

preparation for reassembly.

Reinstall Stationary Base into Revolving Turret

Hold the stationary base such that the center pivot is

facing downwards, and lower the stationary base into

the recess of the revolving turret (see

Figure 23 – Reinstall stationary base into revolving turret

Apply Ring of Grease for the Perimeter Balls

The next step is to apply grease into the ring in which

the perimeter bearing balls will be placed. Carefully

apply a ring of grease (item S2 of

channel formed between the outer perimeter of the

stationary base and the inner perimeter of the revolving

turret (see

Figure

24). Do not apply too much grease

here, to minimize the squeeze-out that will occur when

the threaded retaining ring is reinstalled to hold the

stationary base into the recess of the revolving turret.

Reinstall the Threaded Retaining Ring

Carefully engage the threads of the threaded retaining

ring with the threads in the revolving turret (see

threaded retaining ring

Figure 27 – Tighten the threaded retaining ring

Or use a center punch or nailset tool to snug the threaded retaining ring by placing the
