3500B additional camshaft hall sensor installation

[ Edited ]

Dear all,

looking for any picture and technical drawing of the Caterpillar 3512B camshaft group.

we have to install an additional trigger magnet  and hall sensor to locate TDC for our AKC system on a BiFuel conversion.

Following some pictures of the 3500 A spec series camshaft front end and how the sensor mounting was done there (3512A).

Question is if something similar is possible on the B spec engine? Hope somebody could help. Every piece of advice would be great!
