Removal, service and installation of the oil pump

Removal

The Reduktsionny valve can be removed without preliminary dismantle of pump assembly.


 PERFORMANCE ORDER

  1. Remove a belt of a drive of GRM (see. Removal and installation of a belt of a drive of GRM).
  2. Remove cogwheels of cranked and distributive shaft, and also a natyazhitel of a GRM belt (see. Removal and installation of a natyazhitel of a gas-distributing belt and cogwheels of a drive of GRM).
  3. Turn out bolts of fastening of a back cover of a drive of GRM from a head of cylinders and the case of the oil pump, uncover the engine.
  4. Remove the pallet of a case and a maslozabornik (see. Removal and installation of the pallet of a case).
  5. Disconnect electroconducting from the sensor of emergency pressure of oil.
  6. Turn out a bolt of fastening of the sensor of provision of a cranked shaft, take away the sensor from the pallet.
  7. Turn out bolts of fastening of the case of the oil pump. Extremely carefully remove the pump case from a pin of a cranked shaft — try not to allow losses of directing plugs. Remove sealing laying of the case. Laying can be thrown out — at assembly it is subject to replacement without fail.

Service

 PERFORMANCE ORDER

  1. Turn out fixing screws and remove a back cover of the pump.
  1. Marker (at all center punch and not chisel!) mark the adjusting provision of internal and external gear wheels of the pump — at assembly components should be established strictly similarly.
  1. Take internal and external gear wheels from the case of pump assembly.
  1. Turn out from the assembly case a cap of the reduktsionny valve, take from a landing nest a spring and a plunzher — try to remember the adjusting provision of components. Remove from a cap a sealing washer.

    1 — Plunzher
    2 — the Spring
    3 — the Sealing washer
    4 — the Cap

The valve can be disassembled without preliminary dismantle of the pump.

  1. Carefully clear all components and attentively examine them on existence of signs of excessive wear, chips, задиров and other mechanical damages. The failed elements replace. In case of detection of defects of gear wheels or the case all pump assembled is subject to replacement.
  1. If the condition of components is found satisfactory, measure with the help щупа lezviyny type gap size between teeths of internal and external gear wheels, and also size axial люфта gear wheels and planeness of a cover. If the result any of measurements falls outside the limits an admissible range (see. Specifications), replace pump assembly.


  1. Assembly of the pump is made upside-down. Pay attention to the next moments:

    1. Make sure of correctness of installation of both gear wheels (see the marking put in the course of dismantle).
    2. Do not forget to replace a sealing washer of a cap of the reduktsionny valve — a cap tighten with demanded усилиемю
    3. Before a vvorachivaniye clean a carving part of fixing bolts and put on it a layer fresh hermetic, track, that all fixture was tightened with demanded effort.
    4. On termination of assembly fill the pump with fresh impellent oil, manually rotating its internal gear wheel.

Installation

 PERFORMANCE ORDER

  1. Before installation of the pump remove from its case an epiploon of a cranked shaft, having accurately hooked it approaching Russian cabbage soup a shlitsevy screw-driver. Fill a new epiploon with sealing sponges in the engine. Press an epiploon by means of a cylindrical opravka aflush with the pump case. Track, that the opravka rested only against the rigid external region of an epiploon.

As an opravka it is possible to use a replaceable face head of the suitable size or a piece of a pipe of the corresponding diameter. Having planted an epiploon, grease its sealing sponges with pure impellent oil.

  1. Make sure of absoluteness of purity and dryness of interfaced surfaces of the case of the pump and the block. Track, that directing plugs were on the regular places.
  2. Establish on the block of cylinders new sealing laying.
  1. Accurately establish the pump into place — track correctness of input of an internal gear wheel in gearing with facets of a cranked shaft. Extremely carefully plant pump assembly on directing plugs — try not to damage epiploon sponges about ledges (1) and facets (2).
  1. Screw bolts of fastening of the case of the pump and tighten them with demanded effort.
  2. Connect electroconducting to the sensor of the sensor of pressure of oil. Establish on the place in the pump case the sensor of provision of a cranked shaft (CKP), screw and tighten with demanded effort a bolt of its fastening.
  3. Establish a maslozabornik and the case pallet (see. Removal and installation of the pallet of a case).
  4. Establish on the engine a back cover of a drive of GRM — track, that fixing bolts were tightened with demanded effort.
  5. Establish cogwheels and a natyazhitel of a belt of a drive of GRM (see. Removal and installation of a natyazhitel of a gas-distributing belt and cogwheels of a drive of GRM). Establish a gas-distributing belt (see. Removal and installation of a belt of a drive of GRM).
  6. In summary replace the oil filter (see. Head Routine maintenance).
