Road wheel clearances

[Erichornby]

Evening All.
Build is proceeding well and have finally got round to installing the road wheels onto the axles. Wheels have been completed with bearings, shims and rubber infills /tyres. Fitting wheel onto axle CV0211A gives interference between wheel rim CV0209 and Torsion Bar CV0206 when trying to fully locate the bearings onto the axle. The interference is sufficient to lock the wheel. Tried every combination of wheel assembly/axle and I am unable to achieve full location of the bearings/wheel assembly without binding. Placing a 2mm thick M10 plain washer onto the axle appears to work for some axles, the remainder requiring 2 washers to achieve clearance between wheel rim and Torsion bar.
Unfortunately, placing packing washers between the rear bearing, 6000 2RS, and the face of the axle CV0211A reduces the bearing support area for the outer bearing 698 2RS. Additionally, placing the securing washer CP0142 and M4x8 CSK screw in position then loads the bearing, due to the clearance introduced between the end of the axle and the end of the bearing.
Measurement would indicate that the maximum discrepancy on the road wheel rim to rim measurement is 0.4mm and axle and bearing to bearing dimensions is also within 0.2mm. I can only assume that the tolerances measured are within those allowed for the different manufacturing processes and none would explain the poor fit being achieved.
It would appear that each axle 20 mm dia section should be increased from 10.0 to 11.5mm to allow the wheel bearings full location and maintain clearance between rim and Torsion bar.
Has anyone had similar problems and how have you achieved a satisfactory solution.

Best regards

Eric, can you post or email us some pictures of your assembly.

Evening All,
Your prompt reminded me to have another look at drawing 17 and, I should have realized earlier.. I had one wheel mounted on the back of the flange so reducing clearance between the suspension arm and the wheel rim to minus 2 mm. Follow the layout shown, don't assume, and everything starts to work correctly.
Have now rebuilt 7 of the 14 wheels, just the remainder to build, mask and respray. Really enjoy duplicating work
Many thanks for the advice.

Hi Eric.
You should try building the Chieftain
(All meant in the best of humour)

Take care

Hi Charles, looks as though you are a bit of an expert with the range listed!! I'm used to cross sectional drawings and seem not able to visualise the assembly requirements from explored views. Hope that improves as time goes by.
