Title: Penn 704 rebuild
Post by: Jerseybros on March 19, 2017, 07:44:37 PM
I know this has been done before, but I took a couple pictures throughout the process of restoring a penn 704.

So here's what we are starting with.  Very tight to crank, and lots of surface corrosion:

The first thing that I started with was disassembling the reel:
Undo the drag knob first and remove the spool.

Next using a flathead screwdriver remove the side plate by take out the three screws holding it on the housing.

Removing the screw threaded through the crosswind and spool shaft allows us to slide out the shaft.
Using our pliers we loosen and remove the nut holding the rotor to the pinion shaft and we can then remove the rotor(cup).

Once the cup is off we can pop off the rubber spacer by hand.
And three more flathead screws give us access to the pinion bearing, and also to slide out the pinion shaft.

Winding the handle backwards unscrews the handle from the main gear, allowing the main gear to slide out the housing.


This leaves us with a fairly empty housing and this is the stage that I will start with the photos:
Here I've started to drill out the pinion bushing with a 12mm drill bit,
I've also used the same bit to drill out the main gear inside bushing and then popped out the rest of the bushing with a hammer and screwdriver from the outside.

Here you can see the drilled pinion bushing and main gear bushing, I've also pressed into place the two bearings that will replace the bushings!!

Taking a break from the internals of the reel, I marked out the rotor(cup) to be drilled and went to town first with a smaller bit as a pilot and then using larger bit of your choosing. 

Popping a dremel wheel attachment into my drill I connected the holes to make rudamentary slots that I then went back with a hand file to clean things up.  I also removed the far side bail attachment with a hack saw and filed smooth.

Same treatment drilling the spool.

On the top lip of the spool make sure to de-burr the holes very well.  I went back and hit them all with a round file as well to round the outside edges of the holes so that when casting, any loose line that gets compressed into the holes may easily unwind off the spool without binding in the holes.

On the side plate, the original emblem was missing, and was severely corroded so I filled the indent with epoxy and sanded smooth for paint.

Back to the inside of the reel.

One of the things I don't like about these reels is the line lay.
Even with mono they give you the hourglass shape which hurts casting distance and can cause wind knots.

Similar to how van staal and zeebaas fixed this, we need to change the shape of the cross wind to gain a more even line lay.

The first two pictures show how I drilled out the original cross wind, filled the gap with epoxy and then redrilled the crosswind to an "s" shape.  The third picture is one I found online where someone made a whole new crosswind with the "s" pattern.  The correct way to do this is to make a new crosswind, however I do not have the tools required to make this piece, so in the meantime the epoxy version will hold up just fine.

At this point, give all the parts a good cleaning and I went ahead and put on a couple coats of paint.

Now we can reassemble the reel following the reverse of the steps listed in the first post.

And viola we have a finished reel.

This will be great in the surf here and on the boat.  Now upgraded to have 3 bearings and fixing the line lay.

Thank you,

Flat black automotive spray paint.
We shall see how it holds up.

It looks good. I have a beater 704, I might try and do this. I'm a big 704 fan.

Did you use a drill press to do the drilling?

If you feel inclined, please post back your opinion on how the paint holds up.

Very nice and not that easy to do.

I have a 706 with 2 one way bearings plus the dog is still in place. I had it built for my grandson. It was mine in the 70's and then my son's in the 80's.

Rick Champagne did the work for me. Its painted in the Florida gators orange and blue with a white side cover. The emblem hole just like you did. We then found a Gators sticker for the side cover.

Ill post a picture soon.

The needle bearing on the main shaft is an anti-reverse bearing so this one has instant anti-reverse with the dog as a backup.  I wanted to see if anyone would pick up that it was in there.

What locations are your bearings?

I have done one other 704, and a 712.  These are pretty simple and great reels that have been used day in and day out for years, and will continue to do so.

I used a hand drill, dremel and a hand file to do the rotor cup and spool.  Takes a little longer and a little more effort but you don't need fancy machinists tools to do this!!

I've been polishing an old beat up 704z. I was a little afraid to take a drill to the rotor and spool, but now because of your post I think I'll go for it

So a little update on this.  I got bored so I'm now up to 8 bearings in this thing.  Three on the main shaft(one instant anti reverse), two on the pinion shaft, two in the knob, and one on the line roller.

Big exterior changes are the new Eva knob and the Mitchell line roller!

Now that the new line roller is on there I was able to spool up and fine tune the line lay.  This thing casts a country mile and the braid flies off the spool with the modifications to the crosswind!

All set for the spring bass run!

Nice!  I'm just getting the hot rod spinner bug.  How much pressure is on the cross wind and how will the epoxy hold up?
Title: So far so good
Post by: Jerseybros on May 24, 2017, 03:55:12 PM
Have had this out on the boat a couple times and at the surf a few as well.  Put it through the ringer yesterday after work with a couple dozen blues, and a thorough sand and salt water dosing.

So far the crosswind is holding up, I do plan to make a real one at some point.  And the anti reverse bearing had no problem stopping these chopper blues without the dog engaged.  I expect it to eat into the main gear shaft eventually but this is half a trial run to see how long its gonna last with macgyver'd parts.

Self wrapped rod, hotrodded reel, homemade plug + screaming drag = priceless!!

Hell yeah! Always loved the tough matte black look and it works well with this Penn Staal. One thing with those early greenie spools is i've read they're pot metal and can crack when drilled out like that. This topic was discussed on the Stipersonline forum. An aluminum one from a Z series might be the answer. The AR bearing mod is sick!
