[TR] 72 TR6 front seal

[DAVID MASSEY]

The first step is to remove the radiator.  That is necessary be make room to remove the fan assembly and the access the bolt that secures the pulley.  Once the pulley is out you then remove the timing chain cover since the oil seal is installed from the inside.  

If you go to Roadster factory:  https://trf.zeni.net/TR6bluebook/13.php  you will need AF17 cover gasket and AF20 oil seal.  Note that the seal seals up against a sleeve that will come out with the pulley.  Odds are there is a groove worn into this sleeve where the seal rides.  This is from the grit that embeds itself into the seal and grinds away at the steel sleeve.  The oil seal's effectiveness is dependent on this sleeve having a smooth surface which will no longer be there.  I suggest you replace this sleeve as well.

Assembly is the reverse of the above.  Pay attention to the timing chain tensioner and make sure it is positioned properly.  

Depending on how many miles you have on your car, how much confidence you have in your mechanic abilities and how susceptible you are to Shipwright's disease, you may want to replace the timing chain while you are at it.
