Replacing right crank seal Tri-z- Help!

[Tri-Z Pilot]

How do you get the nut off the idler gear without it moving, so you can replace the right crank seal?

[denn]

The only way I ever did it was with an inpact wrench. Just throw it in reverse and jog it once or twice, It will loosen and spin right off.

Dont have one, any other ideas?

[davham]

Use a penny. Put the bike in gear and hold the brake. Put the penny between the gear and clutch basket gear.

[denn]

Ok, If your cylinder is off put a fairly large screwdriver through the upper connecting rod hole (with the needle bearing out), slowly turn the nut on the gear until the screwdriver bottoms out. This will stop it from turning. Make sure you center the screwdriver and push the rod all the way front or back so when the connecting rod comes down the screwdriver is to the outside of the cylinder nuts. I've done this a million times it will not harm anything. If your cylinder is not off put a rachet on it and try wacking the end of the rachet handle with a this might shock it loose.

The penny trick did not work, just bent the hell out of it! Probably because I do not have brakes, and the clutch slips, any other ideas?

[davham]

Get another penny and use a to smack the wrench. Just dont use any other pocket change, you can damage the teeth.

[Tri-Z Pilot]

So give it a quick smack to jar it loose? Why a penny? Is it softer than the gear teeth?

[davham]

Yes a penny is softer, you could try a dime but use caution. You dont want to chip the teeth and you definately dont want to use a nickel or quarter. Having brakes would help prevent the tranny from turning.
Go back to Denn's post, if you cylinder is off do it the way he mentioned it will work. I've done it this way but have used small blocks of wood to prevent the screwdriver from damaging the gasket surface.
Just dont lose your cool and become a "ham fisted" mechanic, parts aren't cheap.

I can only guarentee that any mistake made will cost more than a cheap impact.

Hey dude, the penny trick DOES work. I had already split my crankcases, but I slapped them back together real quick, used a Craftsman 1/2 drive torque wrench(just like a breaker bar but longer), put on the socket(I didn't have the right size, so I had to use a bit bigger, but it still worked), I put the socket on the nut, jamed the penny in the gears, put my foot on the bottom end to hold it and got it right off. I wish I lived nearby you, it took me a total of 30 minutes to bust down my whole engine, minus the primary gear nut. Wheeeeee!

[Tri-Z Pilot]

really, I mangled two pennies today, with no such luck. I went to put the trike away, tried to take it out of gear and the shifter had no resistence or clicking. I guess denn said sometimes right behind your clutch basket there is a shift fork that has a spring that sometimes pops off when you have the side case off, so I am going to go buy an impact driver to get the clutch basket off to see what the problem is.
