THE GENERAL DATA

Bolts Torx

And – a bolt with head Torx (an external six-coal asterisk),

In – a bolt with nest Torx (an internal six-coal asterisk)

TRANSMISSION OF TYPE WITH

Nave of the synchronizer of transfers 3–4

Since January, 1983 (a code of date of manufacturing "DC") in mechanical transmissions of type With naves of the synchronizer of transfers 3–4 new types are applied. This change is entered for elimination of vibrations of a ring of the synchronizer, arising in not included synchronizer. The entered change does not influence a method of dismantling and the transmission assemblage, resulted in subsection 6.1.5.

Fastening back картера

Since March, 1983 (the code of date of manufacturing "DD") back картер transmissions of type With fastens by means of bolts with a head of type Torx.

In the course of unscrewing and a tightening of these bolts necessarily use of corresponding tools (Torx E12) these bolts adapted for heads. Use of the inappropriate tool will cause damage of a head of a bolt.

Other information, concerning a technical characteristics, adjustment and repair of a mechanical four-speed transmission, is resulted in subsection 6.1.
