Dismantling and assembly of multidisk brake В1

Dismantling

Design of multidisk brake В1


6b — the External support of brake В1 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 brake В1

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 compress it until the groove for a lock ring will not be released.
4. Remove a lock ring (6e).
5. Remove the piston (6c) from an external support, carefully submitting air to an opening (A).

Assembly

PERFORMANCE ORDER

1. Establish the piston (6c) on an external support.
2. Establish a disk spring (6d).
3. Establish a stripper (073) on a disk spring (6d) and compress it until the lock ring 6e will not be established in a groove.
4. Insert a lock ring (6e).

Cut of brake В1


6b — the External support of brake В1 6c — the Piston 6f — the Disk spring 6h — the Lock ring 69 — Frictional disks	70a — the External disk in thickness of 1.8 mm 70b — the External disk in thickness of 3.5 mm / a new disk of 2.8 mm 70c — the External disk in thickness of 4.0 mm L — the Gap

PERFORMANCE ORDER

1. Insert a disk spring (6f) and the block of disks (96g) on an external support and measure gap В1. Insert disks of brake В1 together in an order presented on an illustration, and establish them in turn.
2. Establish a press (078) on an external disk (70c).
3. Compress the block of disks against the stop (the otmetochny ring - a small arrow yet will not seem). 4. Measure a gap of "L" between a lock ring (6h) and an external disk (70c) in three points. The size of gaps in multidisk brake В1 is specified below in the table.

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

Establish the picked-up ring.
