looking good guys ! make sure the plungers in the brake expander are in the correct way, I believe from memory they are "handed"

To clarify: Adjuster unit and Expander assembly.

The brake ADJUSTER plungers are left and right hand, i.e.: "handed".

See part numbers for the handed adjuster unit plungers:
C01UC-105217 R.H. (right hand)
C01UC-105218 L.H. (left hand)

Another thing to consider is the fact the EXPANDER housing is not fixed, but 'floats".
The brake expander housing is supplied with slotted or castellated brass nuts, and Thackery washers to create the necessary tension.
The floating expander housing assists with the brake adjustment

I have a question regarding the difference between the bogies
Rear and front bogies are the same the track adjuster is different catalog number
What is the differences?

The height of the rubber is different. I had noticed that your carrier has the front (adjustment) wheels used on the boggies. Should be working though.

The track adjuster wheel rubber profile can be observed visually, you will see it appears "lower" than the standard bogie wheel. The "higher" rubber profile on the standard 94x3 Canadian bogie wheel is obvious on a side by side comparison. Look also for the markings such as CTL 94 x 3 and CTL 17 x 3.

Wheels and tires should be should be considered as two components. This is because production changes were not concurrent. Ideally you are looking for the latest production, marked C.T.L. 94 x 3 on both components, i.e wheel and rim.

Why? Two reasons:

1) Early "wheel spoke diameter was increased to overcome spoke breakage which occurred with the first type wheel under severe operating conditions."

2)"The rubber in the tires was also modified to overcome blow-out . . ."

Instructions were issued directing that: "first type bogie wheels were not to be perpetuated by re-tiring."

Note: "RE-tiring of the original design bogie wheels with 19" tires for use as track adjusting wheels (CTL 17 x 3) is considered satisfactory practise."

You are likely aware the track adjuster wheel mounts on a spindle using different inside and outside inner diameter bearings. This is unlike the bogie wheels that use two bearings with the identical inner diameter. Those differences also require the application of different related components. See your parts manual illustrations and note the different applications for the following part numbers: TL 18, TL 19, CTL 20B, CTL 21, CTL 22, TL 23, TL24, CTL 25, TL 95, CTL 334, C01UC 100300, C01UC 100301, CTL 1798.
