Removing Crank Gear...

[armbrusb]

Hi,

I am having som difficulty removing my crank gear. It seems to be on there VERY tightly. I can't seem to get pulleys in behind it becaise it is a. very close to the block and b. blocked by the half-circle below the gear which I guess protects it from rocks etc.

Two methods have been suggested to me to remove it. These are to a. tap holes into the gear and use a pulley to yank it off and b. break it off.

I have to admit that I am leaning towards option B as a new crank gear is only $50 and it seems like a few less steps. I would like to know how well people have gone with this? Any help would be fantasic!

Thanks,

Ben.

take option b.

[armbrusb]

Have you done it? Do I use an angle grinder or shoudl I use a chisel. I am a little concerned about damaging my crank or the oil pump using option b. How have you done it? Thanks.

drilled 3 holes side by side in the gear between teeth. Then used a chisel to wedge in the hole, hit it, and split the gear. Came off easy as.

Dont drill into the crank...big no no

Do you mean like this?

WTF are you doing!!!!!!

You don't need to damage the gear in any way, shape or form. It should slide off over the woodruff key.

I wish it did just slide off - but it seems to be very stuck. I am lead to believe that this is a relatively common problem, but maybe we are just doing it wrong. What are the steps you use to get it to slide off?

more like how i shown.

For the effort to get a seized one off, id rather do it this way.

had same problem on a magna v6 a while back, i used to gas torch to heat it up and off she came in a matter of minutes.

dunno if it would help you?

Oh I see. Q: do you strike it with the chisel from the top or from the front?

I drilled into the front and used a gear puller to get it off. Saves hitting shit with chisels.

Mine was rusted on on the old rb20, not that you could see it until the gear was off.

The rb25 one slid off and on easily.
