Edit Reason: Length for BP118 added
)
Hi All
Having discovered our propshaft was the wrong length in that it was lock solid between the fabric joint and the rear flange I did a bit of investigation as I was under the impression there were only two lengths long and short for the the long and short chassis. I discovered that there is a long one for the long wheel base and three for the short wheel base cars. The below is from the Austin Handbooks and the Austin Index Pages ref to the A7 Companion for info.
1926 Handbook 353j Propshaft Part BP28 Three speed box speedo on pulley, Type 1 axle (A7 Companion).
1928 Handbook 353w Propshaft Part BP28 and BP73 speedo on back of three speed box (I guess shorted due to longer gear box), Type 1 axle (A7 Companion).
1930 Handbook 670c Propshaft Part BP73 speedo on back of gearbox, Type 2 axle (A7 Companion)
1931 Handbook 670d Propshaft Part BP93 Increased length due to torque tube change in axle type (this is noted in the index pages), Type 3 axle (A7 Companion).
1932 Handbook 888 Propshaft Part BP93 and BP118 the latter for the long wheel base cars, Type 3 axle (A7 Companion)
1932 Handbook 888a Propshaft Part BP118 long wheel base cars, Type 4 axle “D” (A7 Companion)
Measuring from the fabric end of the propshaft to the middle of the cardan pin I believe the order is as follows.
BP28 original propshaft 20"
BP73 reduced for speedo on rear of gearbox 19.5"
BP93 does anyone know what this propshaft measures?
BP118 26".
We now have the correct propshaft but curious as to the length of BP93.
Thanks
Douglas
