Rob's AK40

[Rob Parker]

Hi Rob,
Interesting to read (and see) your build. Stating the obvious, I presume you are giving feedback to Jon at AK. I'm sure he would want to be advised of any difficulties. He doesn't need grief from customers who are thousands of miles away.
I see you are in the Bristol area ..... I'm a long way from you in the heart of the Norfolk Broads. I have an MDA that I've owned for nearly 15 years. It's fitted with a highly rebuilt Ford 302 and for a laugh the car is painted in proper Ferrari Rosso Corsa red ...... we call it our one finger salute to Ferrari.
Anyway, good speed with your build ...... 2030 is looming so you need to crack on !
Best regards
Steve

Hi Steve,

Yes, I contacted Jon about the issue. I believe he has recently changed supplier for the hubs.

Regards, Rob.

I also had contacted AK about them being stiff, was told it was normal and would free up with use. I had asked about known torques for preload because I was going to open them up and reset them.

Hi Douglas,

I guess you mean the rotational stiffness of hub bearing ?

Jerry, yes, sorry for not clarifying.

Finally, I test fitted everything on the chassis.

The hubs have provision for knock on wheels. The threads are handed; right hand thread on the nearside, left hand thread on the offside of the car.

I have added the brakes too. I need a separate caliper for the handbrake - watch this space.

Would you like a cad file for a bracket to for a Wilwood caliper?

I got that same BS from Mick at Southern GT about one rear hub being noticeably tighter than the other.

Disassembly revealed hubs were not machined the same, the tight one hub OD was too big so they cranked down on the bearings to get it to seat. Dam near didn’t get it apart. My machinist fixed now both torque up evenly and turn with even feel.
