Crankshaft sprocket stuck

[PFFlier]

Hi guys - Newbie here.

 

I'm putting a new timing belt kit in my VG30E and trying to do all the oil seals, water pump, etc while i'm in there but I can't get the crankshaft sprocket off. I put WD40 on, tapped on it while pulling but no luck. I was afraid to pry in the back because I didn't want to ding up the timing belt plate behind the sprocket that keeps the belt in line. Do I need to torch it? Also, do most people install the water pump with just the gasket or do they use the red silicone?

 

Thanks

If you ding up the plate in back just pry that off as well. gently tap it flat again, clean up the ding and open the hole up just barely with a dremel.

Idnno why they made it so it snaps onto a groove in the crank when the pulley pushes it against the sholder protruding from the seal anyway.

Inspect your keyways, the original woodruff key was 2-3mm too short which allowed it to walk into the pulley and out of the crank slot. If you are victum of this and they are worn here is your fix.

 

clean them up and have someone with welder come over.

just put a stich weld in the center of the worn area

get a 18x5mm woodruff key (stock was too small)

using a 1/2"x1/8" grindstone on a dremel clean up the keyway and lengthen it to fit the longer key.

It should fit snug maybe even have to gently tap in w/ hammer. Try not grind deeper just yet.

slide the gear or pulley over the shaft without the key to make sure the saft is cleaned up enough

insert the key and check deepth. make the keyway just deep enough so that the pulley or gear has to be slapped in firmly with the butt of your palm.

 

as for the pump, mine had a felt-like gasket so I smeared just enough RTV on both sides to give it a reddish shine. this also helps it not slide arround when your putting it up. I had abbout 1/32 of squeeze out all arround.
