research for AD'S on cessna 150 fork -

71-22-02 R1 CESSNA: Amdt. 39-1323 as amended by amendment 39-1327. Applies to 150, 172, 175 and 182 series airplanes with 1000 or more hours' time in service with earlier type nose gear fork installed but does not include the above model airplanes installed with nose gear fork bearing P/Ns 0442503-497, 0543043-497 or 0543043-498, or newer nose gear forks identified in current Cessna Parts Catalogues
Tthe fork I have is the later style PN 0442503-497 is clearly visable .

Scaled the fork tube and the fork to set proper lenght - per the plans the fork is nested against the
lower torque link attach point which is a distance or length of 2.120" - the neck on the fork is not nearly that long - and the scaled distance between the torque mount and axle bolt is 11.00" per the plans . The fork was purchased still on the cessna steering tube and was set flush to the bottom of the fork @ 1.475" . This would leave a Gap or distance of 5/8" or .625" of free space to the torque link mount . The fork is a tight press fit and is then bolted with an AN4 - but to remove any potential to shear the bolt and slide the lower leg into the tire ( which would be one hell of a nose wheel landing) I am going to fabricate a 5/8 inch spacer and press it on the lower leg tube snug against the torque link mount - then press the fork to the spacer . This gives me 10 and 5/8 inch clearance between axle and torque link mount verses 11.00" as scaled off plans.
Hopefully 3/8 inches wont be that big of a situation come prop time - I already have a concrete saw - I dont need another.
