Ford Focus automatic transmission 4F27E diagram:
1 - clamping band;
2 - planetary gear;
3, 4, 12 and 13 - multidisk friction clutches;
5 - oil pump; 6 - hydrotransformer;
7 - input shaft;
8 - idler pinion;
9 - differential;
10 - pinion gear;
11 - freewheel clutch.
The automatic transmission with a designation 4F27E Ford is established with the engine of 1,6 l Zetec-SE. The transmission has electronic control and function of blocking of the hydrotransformer. Two planetary numbers available in a gear box create various variants of transfer relations. For Ford transmissions repair required special tools.
Ford Focus transmission iB5 diagram:
1 - clutch working cylinder;
2 - breather;
3 - main drive shaft;
4 - secondary shaft
5 - differential.The transmission iB5 is established with engines of 1,4 l Zetec-SE, 1,6 l Zetec-SE and 1,8 l Zetec-E. With the engine of 2,0 l Zetec-E and both diesel engines transmission МТХ-75 is established.
Ford Focus transmission МТХ-75 removal and installation: remove a wire of "weight" from negative side of the accumulator battery; turn on 5 turns of front absorbers nut rods; remove air filter with the sleeve; remove air intake of cooler; remove wires from candles and spray jet; unhook contact socket from the fan electric motor; unhook contact socket from the switch of backing light and from the speed sensor; remove wiring harness from the gear box; remove the fan; remove catalyst converter from an exhaust manifold; establish shift lever in a neutral position and fix; hoist the car; remove contact socket from the starter; remove cross-section levers of front suspension; remove both drive axiss of wheels; unhook control linkage; remove the belt of auxiliary units; lower the car; unhook the tube from working cylinder of clutch and cautiously tie up a wire; remove the grease separator; fix the power unit by means of various adaptations and prepare for a trunk jack wide enough prorate under an oil crankcase; lower slightly power unit; remove rear engine bearers; cautiously hoist the car; turn away bolts of fastening of the transmission, having left two, and remove the bracket of the steering hydraulic booster; tilt the power unit forward and prop up wooden laths (length about 300 mm); fix the transmission that it has not fallen, and turn out two bottom bolts; remove the transmission. Transmission installation spend to sequences, return to removal, thus: use only new nuts; temove air from clutch hydrodrive gear as it is described earlier; adjust control linkage the gear box as it is described earlier; start up the engine and warm up it to a working temperature; make the trial trip run not less than 20 km. For this time electronic engine management systems and the car should be activated. If you find out failures in engine work, for example non-uniformity of rotation of a bent shaft of the engine idling, it is necessary to go on specialised station Ford where to you will reprogram a control package anew. After the trial trip again check up levels of working liquids, reliability of fixing joints and leakproofness of hoses.
Mechanical unblocking of automatic transmission 4F27E selector: the ignition key can be taken from the lock only after selector installation in position «Р»; for conveyance of the selector from position «Р» it is necessary to engage ignition, to press brake pedal and on the selector button; if you cannot engage ignition unblock the selector manually for any reason; for this purpose insert the suitable tool into a bore located on a left side of the central extension housing, press blocking lever and move the selector.
Ford Focus transmission iB5 removal and installation: remove a wire of "weight" from negative side of the accumulator battery; turn on 5 turns of front absorbers nut rods; remove air filter with the sleeve; unhook the tube from working cylinder of clutch and remove a bracket; hoist the car and remove contact socket from the switch of backing light and a speed sensor; remove a gear controls cover; remove cables from a bracket, having turned clampers clockwise; remove from both parties cross-section levers of a front suspension (fig. 1); remove a buckle of intermediate bearing fastening of the right drive axis of wheels; pull out both drive axiss of wheels from the transmission and cautiously bring by means of a wire to a body heel; a bore in the transmission close a pure rag for prevention of escape of oil; remove a starter; separate a reception tube of the muffler;
remove engine bearers (fig. 2); remove the drive gear belt cover of auxiliary units; lower the car on a floor; remove rear engine bearers; remove clutch working cylinder bracket of the tube connecting; remove rear engine bearer bracket; turn out the top bolts of fastening of the gear box and lower the power unit, how much it is possible; cautiously lower the car; turn out the most accessible bolts of transmission fastening, having left only two; tilt the power unit and prop up its wooden blocks (length about 300 mm); fix the transmission so that it has not fallen, and turn out last two bolts then remove a transmission from the engine. Transmission installation spend to sequences, return to removal, thus:
use only new nuts; temove air from clutch hydrodrive gear as it is described earlier; adjust control linkage the gear box as it is described earlier; start up the engine and warm up it to a working temperature; make the trial trip run not less than 20 km. For this time electronic engine management systems and the car should be activated. If you find out failures in engine work, for example non-uniformity of rotation of a bent shaft of the engine idling, it is necessary to go on specialised station Ford where to you will reprogram a control package anew.
