Gary Gates Posted June 23, 2015 Share Posted June 23, 2015 I am looking for a source for steering sector parts for my 1917 Maxwell Truck. The worm and worm wheel are both badly worn. (Maxwell # 's worm B1739 and Worm wheel 20053) I would like to update it to a reciprocating ball set up like my 1919 Maxwell Truck has. Does any one have any spare parts or know a source?Gary Gates Link to comment Share on other sites More sharing options...
Hudsy Wudsy Posted June 24, 2015 Share Posted June 24, 2015 You might speak with these fine folks. If they can't help you directly, they might be able to refer you to someone. Steering gears and related items is what they do: http://www.larescorp.com/ Link to comment Share on other sites More sharing options...
60FlatTop Posted June 24, 2015 Share Posted June 24, 2015 It seems like replacements could be recast in a foundry that does small jobs. I worked in a foundry years ago and we would cast our own parts for high wear items.Bernie Link to comment Share on other sites More sharing options...
Gary Gates Posted June 26, 2015 Author Share Posted June 26, 2015 Does anyone have experience with an independent foundry or small foundry that has or would consider recasting replacement parts that could be re-machined as replacements? I would prefer a business that I could just furnish the parts to copy and not to completely rebuild the sector. Link to comment Share on other sites More sharing options...
Bhigdog Posted June 26, 2015 Share Posted June 26, 2015 (edited) Machining a worm and gear is not something the vast majority of small machine shops could accomplish. There is quite a bit of complicated tooth geometry to a worm and gear for it to run smoothly not to mention specialized cutters and machines. Not saying it can't be done if enough time and money is thrown at it. Just saying. If you are going to go that route might be better and less expensive to machine them from solid.......Bob Edited June 26, 2015 by Bhigdog (see edit history) Link to comment Share on other sites More sharing options...
Gary Gates Posted June 29, 2015 Author Share Posted June 29, 2015 Thank you for all the good responses! I have some places to check now! One other thought was that if anyone has a 1920's interchange parts book, it might show the sectors mfg. I'm sure Maxwell didn't make it them selves and it was probably used on several cars and trucks. Link to comment Share on other sites More sharing options...
Dan Marx Posted July 5, 2015 Share Posted July 5, 2015 I have a 1932 Chiltons Interchangeable Parts Hand Book and it only goes back to 1927 and it does list worm gear interchanges. What is the earliest interchange? Link to comment Share on other sites More sharing options...
Gary Gates Posted July 5, 2015 Author Share Posted July 5, 2015 Dan, The 27 exchange book is probably too new. The Maxwell trucks were from 1916-1921, then Dodge sectors might work.Thanks for looking. Maybe some one has an earlier cross oldex. Link to comment Share on other sites More sharing options...
Gary Gates Posted August 30, 2015 Author Share Posted August 30, 2015 Members all! Final Chapter to the steering worm saga. A machinist friend was able to polish the worm slightly. We then rotated the the worm gear 180 degrees ( so it is touching with teeth not yet worn). Further noting the sequence of holes in the mounting hub, we discovered that the boss was an eccentric and rotation allowed a tighter alignment on the sector. After this learning process, the result has removed the excess travel in steering and original performance obtained. Sometimes experience is a wonderful teacher!
