It doesn't matter what type of engine, diesel or petrol, the crankshaft seal replacement is a similar procedure.

First you have to remove the box, clutch assembley, check for excessive end float beforeyou remove the flywheel, if this is OK, continue, otherwise now is the time to rectify excessive end thrust.

Hook out the old seal, clean off the crank, check for badly grooved crank seal running surface ( you can sometimes let the seal 'stick out' slightly to enable it to locate on a 'not so worn surface', however if the original surface is OK, clean up and fit new 'lightly oiled' seal, coat the external seal face with 'Hylomar' before fitting.

Re-fitting is the reverse of dismantling, providing you don't need new/replacement thrust washers.

PS. While you're at it, check your spigot bearing for seviceability and lube it if required.

No, they usuall bolt up against a locating boss.

If the seal lip running area is badly scored, another fix is to get it cleaned up a bit - the WBX flywheel I know can be lathe mounted and a lightly ground in a good machine shop. If the flywheel needs refacing (cracked, blued,wavy) this can be done at the same time, but try Rex's tip to seat the seal at a different position if there's a single bad score (but deburr it if the lip has to traverse it when fitting). Don't forget to pre-lube the lip and running area.
