Folks, I have been going back and forth on the forum for months trying figure out the proper configuration and pulley combination to support an F to 2F change. My rig is a 12/72 FJ-40. I put a rebuilt 2F from a 1985 FJ-60 into the truck. I am putting it back together and felt I had done all my homework to make this work but it does not. I am really desperate to resolve this so I can get the truck running and on the road.
The FJ-60 pump with the fan clutch is too long and will not fit. It rubs on the radiator even though numerous folks told me it should fit. I acquired a pulley from a 1973 FJ-40 as I was told it would fit but the front pulley is too narrow and is not aligned quite right. I have searched the threads high and low for answers and have come up empty. Again, I really need help.
Here is the set up with the 1973 pulley on it with a washer shim behind the pulley to try and make it line up. The belt is too large for the pulley size and it does not line up which I am sure will cause wear issues on the water pump etc... Can anyone guide me in the right direction? Again I am getting desperate here. I appreciate the earlier input but all the previous advice does not seem to work. What the am I missing????
I really appreciate the help.
