6b — the External support of a brake B1 6c — the Piston 6d — the Return disk spring of the piston 6f — the Disk spring of the block of disks	6g — the Block of gear wheels 6e, 6h — Lock rings 073 — the Stripper A — the Oil channel of a brake B1

PERFORMANCE ORDER

1. Remove a lock ring (6h).
2. Remove the block of disks (6g) and a disk spring (6f) from an external support.
3. Establish a stripper (073) on a disk spring (6d) and squeeze it until the groove for a lock ring is not released.
4. Remove a lock ring (6e).
5. Remove the piston (6c) from an external support, carefully giving air to an opening (A).

Assembly

B1 brake section


6b — the External support of a brake B1 6c — the Piston 6f — the Disk spring 6h — the Lock ring 69 — Frictional disks	70a — the External disk 1.8 mm thick 70b — the External disk a disk of 2.8 mm 3.5 mm thick/new 70c — the External disk 4.0 mm thick L — the Gap

PERFORMANCE ORDER

1. Insert a disk spring (6f) and the block of disks (96g) on an external support and measure B1 gap. Insert B1 brake disks together in the order presented on an illustration, and establish them in turn.
2. Install a press (078) on an external drive (70c).
3. Squeeze the block of disks against the stop (the otmetochny ring - a small arrow will not seem yet). 4. Measure a gap of "L" between a lock ring (6h) and an external disk (70c) in three points. The size of gaps in a multidisk brake of B1 is specified below in the table.

In case of need adjust a gap by a selection of a lock ring (6h) of the required thickness. Lock rings 2.6, 2.9, 3.2, 3.5, 3.8 and 4.1 mm thick are issued.

Establish the picked-up ring.
