Cam Bolt/Intermediate Shaft Weights
Cam/Intermediate Shaft Bolt and Washer = 77.65g
The bolt is M12 x 1.5 x 50mm
¼” Thick Washer – Beveled (Bellville?)
Washer O.D. 1.220” (about 30mm)
New Never Used Intermediate Shaft w/Key and Fuel Pump Lobe = 1175.45g/41.46oz/2.59lb
New Never Used Intermediate Shaft w/Key and center machined down to 0.775” =
1017.61g/35.89oz/2.24lb
Difference of:
157.84g/5.57oz/0.35lb after machining.
From the Hot Rod 2.2 Complete Review catalog, it says Koffel’s shaft with key weighs 2.5lbs before machining (which is what I got as well) and 1.5lbs after machining. It HAS to be gun drilled to save that much weight?
Used Intermediate Shaft without key but with Fuel Pump Lobe = 1173.45g
From the above, the key should weigh = 2.00g
