Electrical: Front cam seal repair

[1 dude]

Hey my 1990 240 is leaking from the cam seal, Im thinking I can fix it, and do a new timeing belt at the same time, from what I understand the belt is marked, and the pullys as well? and am I going to pull the top pully? and does that come off easy or do I need a special tool? I do have a wheel pull tool.
If there is a link or something that would be great
I know Im sounding dumb but I fix things all the time, just want all the info upfront
Thank you

You don't need a special tool, just something to stop the sprocket turning when you undo or do up the bolt. You can wedge a screwdriver through a hole.
You need to release the bearing cap, which means slackening all the others too progressively to avoid risk of straining or breaking the camshaft.

If there is wear ridge or scour mark on the shaft where the seal has been running it's a good idea to put the new one in a slightly different position. I believe I have read a tip somewhere to simply push the seal right in and put another on.

The cover on top of the engine with the oil filler cap built into it. It will be either black or silver
