While inspecting the high gear assembly on a 1970 TBolt I noticed that the bushing appeared cracked on the outer portion. I pulled out another from a parts box & found it to be cracked as well. After researching the problem I discovered that this bushing is of the split variety and that replacements are actually available, if needed. But a new question arose when I discovered that the two bushings differed greatly in the distance that they extended from the end of the assembly (see photo). Is there a prescribed amount for this distance or is it set up for each individual transmission? Any insights appreciated.
if it helps any the one on the right looks correct. its possible the one on the left could have broken off as a groove gets worn there from the seal thats in the plate behind the clutch basket. i replaced a set of bushes in a '65 tears ago but ill be damned if i can remember what the spacing was. I WANT TO SAY (but not sure) that those bushes, and there two, press in til they but up to each other and the result is the correct protrusion. i DO remember they required a light reaming afterwords.
The bush needs to extend enough so that the oil seal in the primary case has something to run on, not critical , just long enough and a wee bit more. When I replaced these bushes I had to ream them to get a running fit, used an expanding reamer.
