Has anyone modified the TR-4 / TR-6 tranny layshaft assembly to
accept larger, higher capacity bearings? Turns out the root cause of
my transmission failure was the failure of the front needle bearing
in the layshaft assembly. Before I do the parts search / purchases,
I thought I'd check to see if there's a longevity improvement that
can be made there.
It's been a while since the box was apart, and let me tell you - with
a buggered up layshaft shaft the disassembly is challenging.
I'll be replacing, input shaft, layshaft and 3rd gear at least. Also
had a weird failure where one of the pins that the spring slides onto
in the overdrive is broken off - may have been an assembly issue.
I may have most of the parts needed for the rebuild, we'll see what
uncle jack's tranny parts stash includes.
Cheers, Tony Drews
