How do I repair 53 year old landing gear?

Mike,
 
Where would I find information on repairing the landing gear for a 1947 bonanza 35 Model D831?
 
Thanks,
Kitty
 
 
Kitty;
 
Although the Beech 35 Shop Manual is the most likely answer, you have apparently run into a problem not specifically addressed within its pages. If you don't have a copy of this book, I would highly recommend it; it is available from any Beech (Raytheon) parts dealer.  Being as how you have an early, straight 35, you wouldn't need to order the supplement - that only contains data for the 33's (Debonair).
 
If you're concerned about landing gear rigging, be certain your technician fully understands the procedure and has all the correct equipment (including the manual) on hand prior to starting the project. If the manual doesn't specify it enough, a couple of pitfalls to be aware of:

1. Be certain you have an auxiliary power source; the battery is not good enough.  If you use a charger for boosting, follow the guidelines published for output. 
2. Be certain the overtravel is set correctly.  Several so-called Beech experts have rigged the landing gear to stop at the end of the sector gear, "to get full travel".  Wrong. 
3. The nose gear retract system can appear to have minimal play in bushings, etc., but, with proper downlock tension, you may be light on up stop tension.  Re-check those bushings.

If there is a more specific area you need guidance on, please don't hesitate to e-mail.
 
Gear Green,
