Year: 1990
Make: Toyota
Model: Pickup

Hi, Folks.
Happy 4th!

I have done an engine swap into my 1990 Toyota pickup and wish to retain my original 10PS15C pump. I have realized that the donor engine (2000 4Runner 5Vzfe) came with a 10PA17C pump and therefore will not accept my smaller 15 due to the fact that there is approx. 10mm difference in length and thus the belt misalignment. I could possibly try to scrounge the wrecking yards to find another pulley with less offset than my current one or, is there any issues associated with putting the 17 in this truck? I am running R12 still and I will freshen up the 10PA17C with new seals and replaced with mineral oil.
Thanx!
Bud

Did you change out all your pulleys to run a v-belt system?

The current engine config uses a 4-groove belt and I had previously swapped out the old single v-belt pulley with the one from the donor engine. Well, I hit the junk yard today and came back with three different pullies that I "eyeballed" for a possible fit as the offset looked possible. I found a 6-groove unit from a Jeep Cherokee, another 5-groove from a Toyota Camry and lastly, a 4-groove one from a Corolla. I settled on the Jeep one as it is a perfect fit aside from two extra grooves. Same diameter and the same 40-degree pitch on the grooves. Problem solved! The 4-groove Corolla one fit as well but the OD of the pulley was considerably larger and, although it too would have worked, it would have spun slower so I kept the Jeep pulley on it. I sealed the system and pumped some N2 into it so I will let it sit that way until tomorrow and hopefully have a nice, tight system. Thanx again! Bud
