Due to an issue I found (from a previous owner(s?)) - I had to do a deep dive into my front spindles. The results are interesting, and I wanted to see if I could determine if I have original spindles, and if not, what the source is.
The Problem (Corrected):
I kept losing preload on my front passenger wheel bearing. It turned out the inner bearing race that was installed in (both sides) was undersized, and the PO had installed a brass shim. On the pass side - the shim hadn't perfectly engaged the bearing, and slowly was being crushed, allowing the race to drift slightly towards the upright. On the driver side, the shim was installed "properly" (if you can call it that), and the race was fully seated in the hub.
I know what bearings & races I need - the information below is intended to help identify the source of the spindle.
The Bearing & Spindle Dimensions:
I believe the components of interest in the front of should be (mostly) Triumph TR6. I have a TR6 Hub and Rotor, TR6 Calipers and Pads, and was able to use "some" of the TR6 Bearing components, as listed below:
Inner Bearing: Diameter Source Comment
Race: Timken L44610 1.980" OD ???? Undersized - Shimmed
Race: KOR 07210X 2.000" OD TR6 Correct Size - Fits Hub - Delivered in a Lucas Box Market TR4-TR6
Bearing: Timken L44649 1.062" ID TR6 Correct Size - Fits Spindle - Was on Car from the PO
Bearing: KOR 07100S 1.000" OD ???? Undersized - Doesn't fit spindle - Delivered in a Lucas Box Market TR4-TR6
Outer Bearing: Diameter Source Comment
Race: ??? (Installed) 1.575" OD TR6 Correct Size - Fits Hub - Delivered in a Lucas Box Market TR4-TR6
Bearing: KOR 03062 0.625" ID TR6 Correct Size - Fits Spindle - Delivered in a Lucas Box Market TR4-TR6
Conclusion & Question:
So I am going to use the KOR 07210X Race and Timken L44649 Bearing (after checking with the Folks at Beaver Bearing that they are compatible). But - what car is this spindle from? It's not TR6, and I thought Herald / Spitfire / GT6 were SMALLER than TR6 components.
Any wisdom from this august group?
Thanks -
Rocky
