    FORM-IN-PLACE GASKET

    The engine has several areas where the form-in-place gasket (FIPG) is in use. To ensure that the gasketfully serves its purpose, it is necessary to observe some precautions when applying the gasket. Beadsize, continuity and location are of paramount importance. Too thin a bead could cause leaks. Too thicka bead, on the other hand, could be squeezed out of location, causing blocking or narrowing of thefluid feed line. To eliminate the possibility of leaks from a joint, therefore, it is absolutely necessary toapply the gasket evenly without a break, while observing the correct bead size.The FIPG used in the engine is a room temperature vulcanisation (RTV) type and is supplied in a 100-gramtube (Part No. MD970389 or MD997110). Since the RTV hardens as it reacts with the moisture in theatmospheric air, it is normally used in the metallic flange areas. The FIPG, Part No. MD970389, canbe used for sealing both engine oil and coolant, while Part No. MD997110 can only be used for engineoil sealing.

    Disassembly

    The parts assembled with the FIPG can be easily disassembled without use of a special method. Insome cases, however, the sealant between the joined surfaces may have to be broken by lightly strikingwith a mallet or similar tool. A flat and thin gasket scraper may be lightly hammered in between the

    joined surfaces. In this case, however, care must be taken to prevent damage to the joined surfaces.

    Surface Preparation

    Thoroughly remove all substances deposited on the gasket application surfaces, using a gasket scraper

    or wire brush. Check to ensure that the surfaces to which the FIPG is to be applied is flat. Make surethat there are no oils, greases and foreign substances deposited on the application surfaces. Do notforget to remove the old sealant remaining in the bolt holes.

    Form-in-Place Gasket Application (FIPG)

    When assembling parts with the FIPG, you must observe some precautions, but the procedure is verysimple as in the case of a conventional pre-cut gasket.Applied FIPG bead should be of the specified size and without breaks. Also be sure to encircle thebolt hole circumference with a completely continuous bead. The FIPG can be wiped away unless it ishardened. While the FIPG is still moist (in less than 15 minutes), mount the parts in position. Whenthe parts are mounted, make sure that the gasket is applied to the required area only.The FIPG application procedure may vary on different areas. Observe the procedure described in thetext when applying the FIPG.

    REMOVAL SERVICE POINTS

    A TIMING BELT REMOVAL

    When the timing belt is to be reused, in order to allowre-installation of the belt so that it travels in the same directionas before it was removed, mark the direction of travel withan arrow before removing it.

    Caution

    (1) As water or oil on the belt can seriously reduce itsusable life, ensure that the timing belt, sprocket, andtensioner stay clean and dry while removed, and neverwash them. Parts that have become too dirty shouldbe replaced.

    (2) When any of the parts are oily, check to see whetherthere are any oil leaks in any of the oil seals or thecamshaft oil seal on the front of the engine.

    B TIMING BELT REMOVAL

    1. Turn the crankshaft to bring the piston in No. 1 cylinderto its TDC on the compression stroke.

    2. If reusing the timing belt, use a chalk to draw an arrowon back of the timing belt to indicate rotation direction.

    NOTE(1) Water or oil on the belt shortens its life drastically,

    so the removed timing belt, sprocket, and tensionermust be kept free from oil and water. Do not immerseparts in cleaning solvent.

    (2) If there is oil or water on any part, check the frontcase oil seal, camshaft oil seal and water pump for

    leaks.

    19. Turn the crankshaft two complete turns clockwise andleave it to stand for about 5 minutes.

    20. Check to see if the metal wire, which has been insertedduring installation procedures, can be removed easilyfrom the auto tensioner.If it can be removed with a light force, it indicates thatthe belt tension is appropriate. Now, remove the metalwire. Another indication of an adequate belt tension isthat the protrusion of the rod of the auto tensioner fallswithin the standard value range.

    Standard value: 4.8 5.5 mm

    21. If the metal wire cannot be pulled out easily, repeat steps18. and 19. until an adequate tension is obtained.

    4. LASH ADJUSTERS

    Caution(1) The lash adjusters are precision-engineered

    mechanisms. Do not allow them to becomecontaminated by dirt or other foreign substances.

    (2) Do not attempt to disassemble the lash adjusters.(3) Use only fresh diesel fuel to clean the lash

    adjusters.

    (1) Prepare three containers and approximately five litersof diesel fuel. Into each container, pour enough dieselfuel to completely cover a lash adjuster when it isstanding upright. Then, perform the following stepswith each lash adjuster.

    (2) Place the lash adjuster in container A and clean itsoutside surface.

    NOTEUse a nylon brush if deposits are hard to remove.

    (3) While gently pushing down the internal steel ball usingspecial tool MD998442, move the plunger through5 to 10 strokes until it slides smoothly. In additionto eliminating stiffness in the plunger, this operationwill remove dirty oil.

    CautionThe steel ball spring is extremely weak, so thelash adjusters functionality may be lost if the airbleed wire is pushed in hard.

    NOTEIf the plunger remains stiff or the mechanism appearsotherwise abnormal, replace the lash adjuster.
