7 tooth steering box re-assembly

[ian Simpson]

I am about to re-assemble the 7 tooth steering gear from my 1928 Tudor with new worm and sector and associated bearings.

My question is this: the references I have do not give any empirical clearance or pre-load data for the worm to thrust bearings fit as set by the shims. Is 'tight but not too tight' good enough?

Also, are new shims available should I need them?

Finally: am I being anal? (Please do not answer this, my wife, children, grandchildren, neighbours and passers-by have already told me.)

Thank you in advance.

I would just remove shims until the end play is gone. At most just the slightest hint of getting tighter, but no real force required to turn the shaft.

Like Tom said. I call it quits when I can feel a slight drag when I turn the shaft with thumb and forefinger.
