300 vs 240 Damper Pulley??

[JWW]

I recently bought some power steering components at a local salvage yard. See thread link below, I feel like a got a good deal.

The guy behind the counter talked me out of getting the damper pulley. (Side note: all this came from a 300 CI engine truck). He told me that the whole pulley along with the harmonic balancer would have to be pulled. He told me that it would not work on my 240. I non the wiser agreed and left with the steering box, pump, and bracket. Still a good deal for me.

Is this guy correct? I assumed you can pull the damper pulley by itself. I'm learning as I go on this old truck, any suggestions?

Also, do I need a double pulley fan wheel or will my single pulley fan work OK?

Thanks in advance for the help.

the pulley bolts onto the damper i think.

That is what I thought. I figured you took the one bolt out and pulled the pulley off without removing the balancer, but will the double pulley from the 300 fit on a 240?

Thanks

i dont know that the single bolt in the center will pull the balancer and the pulleys off at the same time. there should be three or four bolts holding the pulley to the balancer.

The yard man is wrong....a 300 harmonic balancer will fit your 240, which doubles as the pulley.

When I was gathering the pieces to install a Bendix PS setup on the 240 in my '67 a few years ago, the 240's lower pulley and harmonic balancer was a single unit and was a single-groove setup. Therefore, I had to get the harmonic balancer from a 300 which had a dual-groove pulley...also built in, they cannot be separated...and are completely interchangeable with a 240. The aftermarket companies even list a single number for both engines.

sorry i told you wrong.

So, when you take the one bolt out, you can pull the balancer off of the crank? (still green on these engines) Sounds like I need to have the yard man pull the balancer off and vola, I have myself a double pulley.

Yep, just a regular everyday harmonic balancer puller is all it takes after removing the center bolt. By the way, you're also going to need the double-groove water pump pulley, in case you don't already have that.

I thought I would need the water pump pulley. Thanks for confirming. I'll get both of those. I guess the guy wanted me to make sure the 300 balancer would work for my 240. I guess I can appreciate it in a way.

JWW,

Maybe it's just me but...

I'd pull it myself, (yeah, you'll need a harmonic balancer puller to do it properly). If they will let you!
Would be nice to know some "yard monkey" didn't mess it up by removing it with a 2 pound sledge hammer!

The yard guy still insists that the damper will throw the engine out of balance. He said the engine is out of a 79, however the truck looks more like a mid seventies model on the grill. I know grills can be changed. However, I told him that the pulley should work and I was willing to take the chance. He tried to tell me he called the local Ford dealership and they said it would not work for my 240. I even mentioned that early 80's inline six pulley wheel would work.

Anyway, I'm going to get the pulley/damper anyway. I'll take some pics and post later.

Thanks

Oh, yeah, Basketcase, I would do more damage than good taking the damper off myself. Thanks for the suggestion though.

I didn't have to use a double belt water pump pulley. I have the water pump/alternator belt and a second belt running the powersteering pump only. Seems to work fine.

My power steering pump brackets are off a mid 80's truck.

The yard guy doesn't know WTH he's talking about. The Ford 240/300 is an internal-balance motor...and besides what we're calling a harmonic balancer is actually not quite correct, it's actually a harmonic dampener. It dampens out the harmonics from the engine, and has nothing to do with the engine's balance.

I agree. Believe me, I trust you guys more than the yard guy. He hasn't pulled the part yet. I'm not to worried about it. If this pulley wheel passes. I'll find another one. It will be a while before I get to install the PS equipment. I was just glad to get the steering box, pump, and bracket. Next I plan to buy the front end and convert to disc brakes.

I tell you, when you get parts for your bump it gets you excited about continuing building it back.

I did the power steering and disc brake conversion back in the summer. IT IS WELL WORTH IT!!!! You won't be sorry.
