PENN 650 SS / 6500 SS Gear Ratio Mystery

[ez2cdave]

Guys,

I was surfing eBay and saw something I had never noticed before . . .

QUESTION : Did the Gear Ratio change between the 2nd Gen 650 SS (4.8:1 ) and the 3rd Gen 6500 SS ( 4.7:1 ) ? ? ?

I saw these images on eBay, all carrying the same Part #, but with different ratio's on them . . . Also, Mystic Reel Parts (MysticParts.com) does not indicate a change and implies that the gears are interchangeable.

Of course, if changing out both the Pinion and Main Gear (I always do gears in "sets" ), then I would expect them to "fit", albeit with a slightly different ratio . . .

Thoughts ? ? ?

Thanks, in advance . . . Tight Lines ! ! !

I tried that with a 6500 Dave. It didn't work. In this particular spinner. The bearings are different and the gears don't fit. In a 7500 and up, you can swap the alloy gears out with a new brass main and pinion.
As you can see, the bearings are different sizes, which means the case is different and a different handle will be required as well.
To substitute a bearing that will make all this work. Well, I can't find one. 8 x 17
The 650 also has a different rotor design than the 6500. The 650 has a keyed ratchet. The bigger ss spinners have the ratchet sitting on the rotor itself. It was just too big of a design change to make it work. So I threw in the towel.

I've been looking at the schematics for both reels . . . I must be going crazy, because they look the same to me. 

With your previous work on this, what changes were actually made ? Do the schematics just not show the difference(s) ?

I attached the schematics for both the 650SS and the 6500SS below . . .

Thanks !

Go ahead and give it a try Dave. My reels might be different. I got the brass gears from Alan Himself. You can see the difference in the size of the bearings and the gear, hence the cases are different as well, so the correct bearings will fit each of them. Short of switching out the entire case or finding the right bearings. I couldn't make it work.. Here is the thread.

I have a 650SS, but not a 6500SS . . . I just noticed the difference in labeling on the Gear Ratio ( 4.7 vs. 4.8 ) and was curious.

Do you think the 6500SS was an "improvement" over the 650SS or more aimed at cost-cutting ?

Thanks !

[Shark Hunter]

I gotcha Dave. I misunderstood. I know the 6500 has one improvement over the 650 as in a beefier handle pivot. I would say the alloy gear was definitely a cost saving measure, but they do things that I don't understand. Such as replacing the brass main with alloy, but the oscillator is brass? The brass main usually has an alloy oscillating gear. I still love the penn ss just the same. They are great reels.!

I believe it was because of the last part of your comment.
This is why I couldn't find a 6500 anywhere , but then I remembered I had one that needed some work.

It isn't just about the labeling, the ID on the bearing on the 6500 is about 1/16 larger.
Also, the bearing on the 6500 gets installed from the inner side of the cover plate, on the 650, it gets installed from the outer side.
If the cover plates where of the same dimensions, you would have been able to swap them to make the gear work. Unfortunately, the 650 plate is smaller, as you could see below

Sal,

That really made it "crystal clear" for me. Now, I understand the difference(s) between the "2nd Gen" 650SS and the "3rd Gen" 6500SS.

I wonder if the 6500SS is the only reel in the "OO" series vs. the "O" series that holds true for ?

Thanks !

Shark Hunter,

I just attached a PDF of your thread on the 650SS vs 6500SS compatibility here on this thread.

THANKS ! ! !

Just found out the reason why it won't work, nothing to do with
the bearings they are the same part number 20A in both the 6500ss
and the 650ss, the problem lies in 2 parts,

1. The side plate has a different part number

2. The housing has a different part number.

For this reason it won't work.

[Fisherman Paul]

Darren you mentioned the rotor cup is different but i just took
my 6500ss apart for spares for 650ss coming and under
the rotor cup it reads/ 27-650.

The handle, side plate, housing and main gear seem to be
the only change from 650ss-6500ss, if it has the same part number
between the 650ss-6500ss for them reels only it must fit.

I have around £120 in spare parts that will fit my 650ss coming.

My 750ss's and my 850ss have the original part for the bronze
crosswind gear.

These reels are 25+ years old so parts that some have in there reels
might not be the original part, if you own a 6500ss reel you will find
the part number came first from the 650ss, the only changes i see
are the main gear (one handle/pivot can be used left hand or right hand crank
with no change to pivot. The side plate and housing is a different
part number.

So in a nut shell order by part number for your original reel
and whether it's a 650ss, 6500s etc it must fit, but trying
to get the gearing to work it ain't going to happen
cause one is going against the grain so to speak.

Can't wait to get my reel ive a bronze crosswind gear
to go in to it out of my 6500ss, but you never know
i could open her up and i could have a spare, part will
fit though as it was put in the very first 650ss's as it was
in the 750ss's and 850ss'ss.

Paul,

Post up some pics, as you work on your reel . . .

Tight Lines !

You won't notice a 4.7 vs a 4.8 gear ratio when using the reel.... I'm wondering if they are the same (count gear teeth and divide main/pinion), but rounded up in one reel and down in the other???

Guys think about it, when ordering a part it goes on part number
for that reel, up the page the chap has the drawings with part number
take a closer look you will see the guts of the parts have the same
part number, but also look at the parts that don't, its the parts that
are different you want to be looking at, well care full of.

The guts of parts for a 6500ss will be stamped/parts 650 well mine are
as you will see from the drawings above, thats why part 24-750
fitted my 750ss, it is the same part thats in your 7500ss reels but was also in the very
first 750ss's hence the part number.

Its the parts that don't match up you have to be carefull off
as it won't work but the same part 0 or 00 will.



If i get a chance to take pics i sure will.
