estelle Help adapting a different half axle to my Estelle

[Aram]

Hi guys,

 

I'm thinking on adapting a different set of half axles to my Skoda Estelle, which I'm at the moment rebuilding its engine. The problem I always have with the axles design is that the woodruf key/hub/nut assembly gets loose very often, so I want to try a different design.

 

The half axles I can have are from Ladas. The design is different: the Lada axle is a typical front-mounted engine with rear transmission. However the bearing is the same and its size gives me room for adaptations.

 

In the inside tip, Lada's has splines, Skoda has pin-and-guide block. I'm aware about precision that this needs, I know it needs to be done in a lathe, welding by hand turning the aligned parts, etc.

 

I can

• cut both axles and weld together the appropriate sides, reinforcing the joint by welding a sleeve, or
• cut the Lada axle and add a reinforcement ring at the pin side (probably an inner track of an old roller bearing).

 

The main issue: the diameter in the Lada axle, where the pin hole would be drilled is less than 30 mm (need to measure one, but I think it is 28 mm); the Skoda's diameter there is 32 mm. So somehow I need to add body or reinforce that tip.

 

My question is: how should I work the inside tip?

When answering, please keep in mind I don't have access to much more than what I describe.

Hello!

I would choose B to avoid unwanted vibrations. Good luck.

Thank you sir. Would that design be strong enough to hold the torque from the pin and guiding blocks?

Hard to say. I'll try to find some specs from the used materials for axles and try to make some simulations.
