I AM WORKING ON RETRACTING THE REAR SHOES ON THIS AXLE. There is two oval holes on backing plate and it appears there is a risty star wheel in each hole. Later today I will use the oxy-acet torch to heat up the "barrel" next to each star wheel. I expect its the brake shoe design with two wheel cylinders per backing plate. I can't find any photos or diagrams on internet nor do I have a service manual. It appears on one side of backing plate star wheel is located in top of oval hole and on bottom of ovaql hole on other side of axle. What I see next to star wheel I am hoping is the barrel that the star wheel threads into. Can anyone give me any photos, diagrams, or suggestions? Thank you. I am having a problem attaching photos to this post

Photo with hole that nut driver can go through to loosen little bar so star wheel can be turned. I discovered today the star wheel mechanism is seized.



I am trying to remove the star wheel mechanism assembly. So far the assembly will rotate back and forth on the backing plate. I can't seem to remove it. Pin in center turns with assembly and on back of backing plate is what appears a rivet head versus a bolt head.

Yesterday we managed to pry drum off. I then figured out how to retract shoes next time. There appears to be a 5/16" or 3/8" cap screw holding a little bar against star wheel. With the drum on a person would rotate the drum so you could stick a long nut driver through one of the three holes that 3 countersunk bolts hold drum to axle. Once cap screws are loosened a person could rotate star wheel from back side of backing plate. Both little bars are perpendicular to shop floor. One photo came in rotated. I'll post more photos later.

The first two photos showing the oval holes, The photos came in sideways. The oval holes are located on either side of axle and are perpendicular to shop floor.
