Cessna FEL Pump

[JamesBe1 84]

I have started cleaning up my FEL pump (it's pretty bad), and was disassembling everything today, and am stuck getting the pulley off. I found that it was held in place by a 4mm allen screw on the shaft collar. Got that out, and the pulley won't come off. Tried tapping it off with a hammer, soaking it in BP blaster, and it still won't budge.

Is there something I'm missing? Any ideas you have would be greatly appreciated.

Thanx,

James

I had to cut mine off my cessna pump. Then I just took it to my local machine shop and they made a new one for it.

Ouch! Just curious, where exactly did you cut it? I might consider cutting mine off (it's fairly rusty) if I can pick up a new one easily.

I used a 4 1/2" grinder with an 1/8# cut off wheel and cut it in half. You won't be able to cut it completely to the shaft but can get it close. Then I cut around 1/2 the shaft making a few small cuts around the collar in pie shapes. Then used pliers to break off the pieces. Mine was real rusty also. I even tried to press it off in my arbor press. I picked up the pulley/shiver at tractor supply and the machine shop supplied the collar. Good luck

Thanx B

Sounds like you had a heck of a time with yours.

I think I'll probably try prying and tapping it off this afternoon. Maybe try a little heat from a propane torch. That's about as far as I want to go. The pulley is not so bad that it has to come off. I figured that since I was stripping and repainting everything else, I might as well do this too. If I can't get it off, I'll just wire brush the heck out of it and clean everything up with mineral spirits before I repaint.

It would be nice to get the pulley off, but the effort may not be worth if for cosmetic purposes.

Have you tried a flange puller???

[JamesBe1 84]

Er, I have a flywheel pulling kit, but this particular pulley doesn't seem to have an open center. I looked around the internet for pics of flange pullers, but they come in various formats.

What would the flange puller I need look like assuming it is something that can pull a pulley with a closed center?

[JamesBe1 84]

My bad. It does not have a closed center on the pulley. I tried my gear puller and heat, and it still won't budge.

I think I am going to leave it in place and clean everything by hand before I paint it.

Thanx,

James

It was a pain to get off. I needed to rebuild the pump that's why I needed it off.

[JamesBe1 84]

I don't think I will be able to get it off without destroying the pulley. From what I read around the interwebs, it's difficult to find the right pulley. Most people get something close and use a bushing.

Oh well, I just spent half the afternoon with several bottles of cleaners and brushes and rags and cleaned every little crevice that I could find. I guess I'll just add another coat of paint on top of all the rest. There was the original red coat, then someone painted everything blue, then a coat of red on top of that. Mine will be the fourth coat in places, lol.

I'm not looking to win any prizes, I just like to kinda do things right when I can. Sometimes, like now, the effort outweighs the benefit.

As an extra, here are a couple of pics of the pump:

OK, so I finally got it apart as much as possible with the exception of the pulley from the pump. I cleaned and repainted everything and installed new hardware. Here is the finished product:

See above for the before pictures.

Try the puller again. Tighten it as much as you are comfortable with, then whack the center screw with a hammer. The shock will help break it free. I had to pull the hub off my D200 axle that way. It took about 2 hours as It was only giving about 1/16 inch at a time.

[JamesBe1 84]

Thanx Coldone (you really need to sign your name for us my friend),

That's some darn good advice, but since it's all painted and put back together, I don't want to tear it all down again.

Besides, last time I started whacking things with a hammer:

I'm a little hammer-shy at the moment

Ouch! Looks like a job for JB and duct tape!

Lol! Maybe even some supre-glue too.

I was thinking of using a j-hook, but since it is broken along the porting itself, I didn't want to take the chance. I found a used block that I am almost ready to reassemble.

I wonder if it's weldable?

Since then, I've been really shy about whacking things with hammers.

For cast iron welding you need to find an old welder, gray haired and hunch backed preferably. I am not a welder so take it for what it is. I have heard that cast can be welded and there are several methods. The one I think stands the most chance of working is to make a small bead and walk away, come back in an hour or two and make another small bead. Continue to do this until the entire weld is made.

I too am "whacking shy" but it does have it its uses. It has taken years of breaking things with hammers to teach me when and how to whack things. Gallagher was an amateur!
