7.4.14. Replacement of an epiploon of a leading gear wheel

Necessity of replacement of an epiploon define on decrease in level of oil in картере the back bridge (owing to oil leak through an epiploon) to the level breaking normal work of a reducer.

Zapotevanie mouths картера and even formation of separate drops in the quantity which is not exceeding specified below norm, is not a sign подтекания. At plentiful каплевыделении define an epiploon condition.

Definition an epiploon condition

PERFORMANCE ORDER
1. Put the car on the lift or a viewing ditch.
2. Clear of a dirt сапун, check up its condition.
3. Having turned away a control stopper, check up oil level in картере the bridge; if necessary, finish level of oil to norm.
4. Clear a mouth картера a reducer of traces of oil and wipe dry.
5. Will hang out the back bridge and put it on supports.
6. Get the engine, include direct transfer and, at speed of 90-100 km/h, warm up oil to temperature 80–90 ° With (approximately during 15 mines).
7. By the included direct transfer, at speed of 100 km/h, define quantity of the oil following for 15 minutes

The leak of oil exceeding 5 drops for 15 mines, is a sign of malfunction of an epiploon.

It is possible to replace the damaged epiploon, without removing a reducer from the car if replacement of other details of a reducer is not required.

Epiploon replacement

PERFORMANCE ORDER
1. Merge oil from картера the back bridge.
2. Ослабьте bolts of fastening of back wheels; put an emphasis under forward wheels and will hang out the back bridge; lower a lay brake and establish the gear change lever in neutral position.
3. Remove wheels and brake drums.
4. Turn away a nut of fastening of a board of a brake to a beam of the bridge and a pusher deduce semiaxes from a differential box.
5. Disconnect карданный a shaft from a flange of a leading gear wheel and take a shaft aside.
6. Check up a dynamometer the resistance moment проворачиванию a leading gear wheel and remember its size.
7. Holding a flange with a special key, turn away a nut of fastening of a flange of a leading gear wheel and remove a flange with a washer.
8. Remove an epiploon of a leading gear wheel.
9. Establish without a warp, оправкой, a new epiploon, having greased preliminary its working surfaces with greasing ЛИТОЛ-24.
The prevention

Not to damage an epiploon at запрессовке, it is necessary it запрессовать not against the stop, and on depth of 2 mm (a maximum deviation «-0,3») between торцем картера a reducer and an external surface of an epiploon.


10. Establish a flange with a washer on a leading gear wheel and, holding with its special key, tighten a nut of fastening of a flange, periodically checking a dynamometer the resistance moment, проворачиванию a leading gear wheel. If the initial moment of resistance проворачиванию was 58,8 Н·см (6 кгс·см) and above the new moment of resistance проворачиванию should be on 9,8–19,6 Н·см (1–2 кгс·см) more initial. If the initial moment of resistance was less than 58,8 Н·см (6 кгс·см) a nut of fastening of a flange tighten before reception of the moment of resistance 58,8–88,2 Н·см (6–9 кгс·см). If at a tightening of a nut the resistance moment проворачиванию is exceeded, disassemble a reducer, replace распорную the plug new then a reducer collect and adjust (subsection 7.4.7.6) see.

Assemblage of the back bridge spend in sequence, return dismantling.
