cat thirty

[Jason 10/D4]

Hi guys looking at the parts book is a split head thirty later than a 13000 serilal #? I always thought I had a late thirty but according to my parts book I have an early thirty style tractor with a mid to late manifold. A 1930 model, two to be exact. Just was wondering trying to gain some more cat knowledge. Thanks, Jason

Are the manifolds different on the split heads? I see the water jackets are different in my parts book. Jason

The split head thirty has the primer cups in the intake manifold, not the head like the earlier thirty does.

Thanks for the replies just trying to gain some more knowledge. Helps when looking at my parts book too. Jason
