29. Use a scraper to remove all traces of liquid gasket from water
pump cover, chain tensioner cover and intake valve timing con-
trol covers.
INSTALLATION
1. Install timing chain and related parts. Refer to EM-64, "Component".
2. Hammer dowel pins (right and left) into front timing chain case up to a point close to taper in order to shorten protrusion length.
3. Install front oil seal on front timing chain case.  Apply new engine oil to the oil seal lip and dust seal lip.
 Install it so that each seal lip is oriented as shown in the figure.
 Using a suitable drift [outer diameter: 60 mm (2.36 in)], press-fit oil seal until it becomes flush with front timing chain case
end face.
 Make sure the garter spring is in position and seal lip is not inverted.
4. Install water pump cover and chain tensioner cover to front timing chain case.
