1928 Buick Master removal of starting crankshaft cap

Recommended Posts

Is there trick or special movement to remove the crankshaft cap?

I can pull it forward feeling the force of the spring but it will not come off.

 

Should I use some more force? I don't wan't to break something...

No chance, the thing is stucked. May be bent or having some dents jamming it. Mine looks not that nice as the one from the parts book:wacko:

Thank you, that helps!

 

I'm wondering why I can feel the backpressure of the spring. The cap must therefor be jammed somewhere at the engine side pressing the spring together when I pull it. I can turn the cap almost free, feeling a light resistance. It seem like the whole spring turns, like clipped to the cap.

I can pull it forward to see the shaft. I cannot see the spring but I can feel the resistance while pulling. Installing a bearing puller and trying to pull with a sledge hammer didn't work either. What came out is something like a greased thread in several pieces...?

Either I leave it in place or I cut it open and look for a spare.

If you are able to see the shaft, then you are past the crankcase cap pin that holds the crankshaft cap in place.  It may also be stuck to the seal cap, and that is pushed toward the cotter pin and collapsing the spring.  The drive pin is the widest part past that point.  Maybe you can squeeze the tube so it is oval in the direction that you want to keep it from hanging up on the drive pin.  If it is hung up on the seal cap, you may need some penetrating oil and some time and possibly heat.  Hugh

Thanks for the picture Hugh, that helps!

 

As I can pass it forward it goes over the drive and cotter pin but I cannot see the seal by pulling it. So most probably the seal is stocked and moves forward collapsing the spring. This will also explain the remains of the greased stuff coming off.

I will try again and let you know.

 

Leif, the cap is aluminium.
