Hi guys, looking for some help again.

I tried fitting the balancer and it stopped short a couple of mm.

Checked it to my fan pulley and definately not lining up.

Pulled it off and measured into timing case 27mm.

Measured balancer and it's 30mm.

Any good advice for a novice gratefully accepted.

 

The balancer is new and fitting to a 202 red motor.

 

Cheers

 

Marty

You'll know when the balancer is seated right home by the change in sound of the hammer blow. BTW, use a block of hardwood not a piece of steel pipe.

Hi Dave, started with the block of wood/soft :-) distroyed a couple of bits. then it stopped moving in so I went steel on steel which got it moving again. Just felt like it didn't want to go in any more. What does the balancer touch inside?  30mm doesn't go into 27mm?

The spigot on the balancer seats up against the crank timing gear.

Looking at your pics you had it seated all the way home.

I like to bake my balancers at about 120 degrees C for half an hour before fitting them. 

 

Remove from the oven with welding gloves, run down to the shed and belt them on with a bit of wood. 

 

Should only take three flogs or so to get them home with this method. 

 

Puts a LOT less stress on your thrust bearing than trying to flog them on cold. 

 

Cheers.

They're nice in a casserole too but it takes a while to soften them up.

a big pot of boiling water on the BBQ - use thick gloves.

Tried 100 degrees a few times, never quiet did it for me, but still, better than cold i suppose. 

 

120 is as hot as im game to go without hurting the rubber part. 

 

All better than a cold fitment though, like a dry pussy i suppose.....Lots of resistance. 

 

Cheers.

Agree with S pack, it looked all the way home in the first pic.
