Thanks for jumping in!

Reed: Actually, it the damper never came off the engine; it's a '74 225 that I installed in the car at the same time. It's a three sheave pulley and worked fine before with power steering. The inside sheave is unused, the second sheave drives the PS pump and the third sheave drives the alternator.

?

If memory serves, the middle sheave is supposed to drive the water pump and alternator and the sheave closest to the radiator drives the power steering pump. The innermost sheave next to the engine drives the AC compressor and/or AIR pump (on vehicles so equipped).

There should be a spacer behind the fan, but I don't recall offhand how thick it should be. The fan should be within one inch of the radiator though. If everything is installed correctly, the stock fan should not hit the crank pulleys even with power steering.

Post subject:	power steering conversion=fan clearance issues
Being older and somewhat lazy (and tired of 5 1/2 turns lock to lock in San Francisco traffic) I am converting my '63 Dart GT to power steering. I obtained a power steering pump w/brackets, steering box/hoses and crank pulley from a '66 Dart GT and have installed it, but now find that the original '63 fan interferes with the crank and pump pulleys. If I use a 1" spacer between the fan and water pump pulley, it clears the PS pulleys but hits the radiator! I hate to go electric fans, but I'm just not seeing a lot of options here. I should also note that the radiator is a late '60's unit (Part #354) and not in really good contrition....might be time to replace! Any thoughts/suggestions entertained.....

Did you get the crank damper pressed all the way back on? Installing PS shouldn't change the distance of the fan from the engine or the radiator. Sounds like you need to get the crank damper pressed all the way on.

Is the radiator an original or replacement? I know on my 2 core Champion there is only about 2.5 inches between the water pump pulley and the radiator.

Reed you are correct inner is the AC, middle is the Alternator/Water Pump and outer is the Power Steering. It sounds like Reed may have been right from the beginning. Your damper my not be pressed all the way on. Can you get an idea of how much space is between the timing cover and the last crank pulley? Should be VERY minimal.

Ok GIGO; I just re-examined the crank pulley and I incorrectly reported the belt order. The inner sheave is unused, the middle sheave drives the alternator/water pump and the outer sheave drives the PS pump. There is indeed minimal clearance between the pulley and timing coverand the belts line up properly. The fan I have came from the original 1963 225 with a single belt crank pulley and no PS or AC. It has no spacer, and needs almost an inch spacer to clear both the crank and PS pulleys. Given the available info, I'm thinking that the non-original 354 radiator projects too far in from the support, and I need a lower profile fan.
