Lots n Lots n Lots of Questions
I have lots of unrelated questions but I'll try to put them in some sort of numbered order. I have a '69 Loadstar 1700 with 5-speed trans and 392 V8, non-improved cooling. The Line Setting Ticket (LST) was attached to the sun visor so it got tore up and shredded over the years. And the truck was manufactured in Canada so the Wisconsin Historical Society has no info on the truck. After careful reassembly of the pieces I attached an exact reproduction below using * for the missing letters or numbers.
First question:
-1- I'm using a MT-112 Master Parts Catalog that someone in pencil wrote "1962 to 1967 models" on it. Are code numbers and therefore part numbers in this book correct to use for my truck?
How to look up part numbers:
-2- The way I understand it, on the LST the first column to the right of the description is the parts book section number. Then you put the section number together with the number in the next column to get the code number. And in the book, the code number in the section index gives the Fig. number of the parts the truck uses, correct? For example, line 21 in the LST is the transmission, and 13-036 makes up the code number for Fig. 13-058 which is my transmission's parts, correct?
More LST questions:
-3- What does 4160 and 704 mean at the top of the LST?
-3- What do the next two columns mean? In the example above, on line 21 what does 0009 mean? And what does "C" mean and how do I utilize that info?
-4- Any ideas what the exact missing descriptions are in any of the LST lines?
Now a few brake related questions:
-5- Using the LST I believe I've identified some of my brake parts. Eventually I plan to rebuild my brakes. And having read about some of the difficulties people have finding the correct Loadstar brake parts, in your opinion do you think it’s prudent I buy the parts I will eventually need now? For example wheel cylinders, part number 684-834-R91 (correct?)? are no longer available and however, when they are available at Napa etc, they are often wrong. I'll need 4 for the rear axle so do you think they will continue to be available as IH new old stock for another year or two, until I finally get around to rebuilding my brakes?
-6- Same question as above for my brake shoe set. Do you agree 386-073-C91 is my correct brake part number?
-7- And in your opinion do you think I should get a new old stock IH brake shoe set now while still available at surplus places?
More LST questions:
-8- Where / how do I find the brake spring kit part number or must I buy all the springs and links etc individually?
-9- Where / how do I find the brake drum part numbers?
And now a question for the more experienced:
-10- For peace of mind, I plan to convert to a dual circuit brake system. Fig 04-281 in my MT-112 parts book appears to show such a system. But it also shows a vacuum power cylinder between the firewall and the master cylinder. For a Loadstar 1700 application would this be used in addition to dual hydrovacs or instead of them?
It appears a dual circuit master cylinder would also bolt directly to the firewall without that additional power cylinder, see fig 04-256. And therefore I would assume in that case the truck uses dual hydrovacs for powering the two brake circuits. To me that would seem more than enough. Just looking for experienced opinions. And trying to keep the truck vintage correct.
Thank you, everyone, for your help in teaching this old dog new things.
