There are many B/C/CA hybreds out there. The 4 spd tranny from a CA will bolt up to the B. ------------- What this country needs is more unemployed politicians-and lawyers. Currently have: 1 D14 and a D15S2. With new owners: 2Bs,9CAs,1WD,2 D12s,5D14s,3D15S2s, 2D17SIVs,D17D,1D19D;1 Unstyled WC |

| Will the B/C PTO housing go onto the CA tranny? |

Make sure you grind off the CA serial number or you will have a CA and not a B :-) ------------- ALLIS EXPRESS! This year: |

| On this same line, I have heard about, but never seen a 5 speed in a WC-WD45. Have any of you ever heard this? |

| I have a CA transmission I want to put on Kaleb's C. He doesn't want to give up the bench seat and the hydraulic pump is missing from the CA. If the C PTO housing will work back, that's the way I want to go. |

As stated above the B had a three speed transmission for it's life. However, I have heard as stated above that some attach the CA transmission to a B and it works well. Did we do it when we sold them? NO I can just imagine it will make it a better unit. Take good care of my favorite. Good Luck! Bill Long |

I have done this. But you will need a complete transmission case, pto housing and ca hydraulic pump. And to put on the B finals you will have to change the CA final drive bearing shell which are in the differential with ones from a B. The CA has larger bearing holders than the B. Atleast mine was that way. early B and 52 CA transmission. ------------- 51 CA, 57 CA, 53 CA(in progress) |
