> patience.  The bearing splitter I found didn't fit perfectly so I had to 
> modify it on my grinder--making grooves for the gear puller to fit into. 
> Next, make sure the shaft of your gear puller doesn't try to thread itself 
> into the hole in the front of the crankshaft.  I had to put a small metal 
> dowel (cut the head off of a bolt)  in that hole to keep that from 
> happening.  It all depends on how big or small your gear puller shaft is. 
> Once you crank the gear puller fairly tight, it's time to douse the shaft 
> with WD-40 and apply heat with your torch to the pulley around the shaft. 
> Then keep slowly tightening the puller, while applying heat (nice to have 
> a 2nd person here also) and it should pull off.

>    Most likely the crankcase front cover oil seal behind this pulley is 
> leaking so plan on replacing it also--and that means the crankcase front 
> cover gasket and governor housing gasket will also have to be replaced.  I 
> also replace the water inlet elbow gasket if it show any signs of leakeage 
> while I have the front exposed.

>    When you put the new pulley on, make sure you oil up the shaft and 
> pulley.  Then use a dead-blow hammer (or a piece of hard wood between the 
> pulley and your sledge hammer) when driving it back on.  You'll have to 
> hit it pretty hard to get it to move back to the original position (which, 
> by the way--you should MEASURE the distance between the old pulley and the 
> housing before you remove it).  You may have to heat the pulley around the 
> shaft if it won't drive back on all the way with just hitting it.
>
>    I hope this helps.  I learned all this the hard way by trial and error.

>> Hi Folks,
>>
>> I'm looking for a bit of friendly advice.  Dad and I decided to do some
>> spring cleaning on the Super A recently.  It has quickly become something 
>> a
>> bit more than spring cleaning though.  One thing I noticed is that one 
>> catch
>> for the handcrank on the crankshaft pulley is broken off.  I always 
>> wondered
>> why it tended to slip on one side... duh...
>>
>> My question is obvious.  What's the procedure for replacing the 
>> crankshaft
>> pulley on a Super A?  I guess I should go ahead and order a repair manual
>> from Binder Books, but it never hurts to ask you all too.
