Title: Diawa DF-100A
Post by: Bill B on September 29, 2012, 09:55:08 PM
Here's a partial tear down of Diawa's DF-100A.  This is a monster sized spinning reel at an affordable price...it won't compete with any of the Penn Spinners, but for casting lead a long distance it will do fine.  One thing I did find out is some of the screws are a little soft so make sure you have a tight fitting screwdriver when tearing it down.  Figured all my Penn's have their own tutorial so I figured I'd do the spinner.

The spool comes of in the usual manner, the drag washer was fiber and could use an upgrade.

Drift the shaft sleeve retaining pin out to the right, push it to the right only, the pin it spined on one side and will not go the other way

The bearing retaining plate comes off next, these screws were a little soft be careful

With the retaining plate off out comes the bearing, the brass shaft centering bushing, the brass spacer, and then the aluminum spacer

Next remove the three screws holding the side plate noting the bottom screw is longer than the other two, at least there was grease inside the gear housing, remove the last screw and remove the shaft retaining plate

The handle shaft pulls out, and remove the brass shaft bushing, the anti-reverse dog and anti-reverse selector come out, make not of the direction of the anti-reverse dog and the selector switch spring is tight in the hole, be carful you don't bend it

Here we are all torn down, except the bail mechanism

Everything goes back together in the reverse order with no surprises, but lots of grease

The shaft bearing was unsealed from the factory so it cleaned up real easy and was hand packed with grease, I'm more worried about corrosion than feather light spinning

All done and back together, no real surprises except the sleeve pin, which drives only one way, was kinda hard to hold the reel, drift and hammer...

Very nice, yes we need to see those as well. By the way, is that banana flavored yogurt on that main gear? ;D
Thanks for sharing Bill.

Thanks for the tutorial,I've got one of those and have put some big fish on the beach with it.For the price they are a great workhorse but that bearing needs to be done after every trip.

I'm a little confused (that's typical but I'm a little more confused than usual!), I've read that this reel has a multi disk drag stack, but I only see one in your tutorial. Are you missing some or is the internet lying to me again?

No the photo is correct it has only one washer.The reel still gets up to 20# of drag but works better at 15#,I changed the washer that came stock with a carbon fiber one that I modified to fit so it is now much smother.

Great, I'm interested because a fedex box will arrive at my door with one in a few days, I'm going to fish it on a 12 ft Penn torque, thinking 60 braid with 40 top shot. Do you remember what washer you used?

It was a ht-100 006-115 drag washer and if I remember right it was almost a perfect fit.Hope it helps.

Post by: Bill B on October 02, 2012, 12:18:07 AM
It'll be a good match for the 12'...I've got mine on a 15' Okuma Tundra, good balance....just be careful when you tear it down, the screws were soft and buggered easily...also the shaft bearing is open from the factory and will allow lots of water and sand into the top of the reel...I fully recommend the banana flavored grease over the standard oil flavored ;D
Title: Re: Diawa DF-100A
Post by: saltydog on October 02, 2012, 01:40:09 AM
I will agree about the banana flavored being better but I recommend a banana cream it is much smoother.Yes the bering should be done after every trip.And those screws are very soft indeed.

Well then, the screws will go to stainless and I'll baby the bearing. I'll pick up the washer before the reel gets here.

Got mine last night, what a disaster. No drag washer and the bearing was full of gunk. Mine also had a small fiber washer on top of the click, and it has some ugly noises under the hood when spun fast. Can't complain for the price, I think I'll get an HT-100 to replace the fiber washer on top of the click. Anyone ever run without the click? I hate the noise and it would be nice to run a flat plate with a bigger washer.

OK, so I finally noticed that mine is missing an A in the name. It is just slightly different. It had a spot for te drag washer and so I put it in and greased the drag top and bottom. The loud clang happens when the cross wind stud hits the plastic ramp in the frame. I think it has excessive play in the shaft and can't figure out the best way to remove it.

Counterfeit? Doesn't usually happen with low-priced stuff, but there seems to be an unusually high number of problems with this one.  If I may ask, where did you get it from?
Title: Re: Diawa DF-100A

Looking at the parts diagram for the non "A" version, it really doesn't seem to have a drag washer.

Excessive play....is that the shaft rattling in the bearing or excessive play in the handle when turned?  Like the anti-reverse?  The loud clang should be the stop that trips the bail....not sure if you can fix that..
Title: Re: Diawa DF-100A
Post by: Ron Jones on October 09, 2012, 02:16:45 AM
The excessive play is in the rotor assembly (#11) it slides up and down the shaft a 16th of an inch or more. I think the loud clang on every rotation is the stud in the winder assembly (not seen on schematics) hitting the ramp on the body (#24) due to the excessive play causing misalignment. It doesn't seem to effect the function of the reel and only happens when it is spun fast. My gut tells me it won't happen when reeling something in. The other thing is that it doesn't have a bearing, more of a bushing in the body that was filthy. Also, the shaft sleeve retaining pin is not moving, at all. I removed the pinion retainer (#25) and pulled the rotor forward enough to clean everything up. With the drag washer in and greased, it has plenty of drag, and is about the perfect size for my rod. I'll fish it as is until it is time for braid and then I'll figure out how to totally tear it down and see if I can put in a bearing from the A model.

Thanks,
Ron

Hello my name is Chuck. Thank you for the tutorial on the Diawa DF/100 A. I have a question about upgrading the Drag washer. I've never worked on a reel before so I need to be very careful. Should a replacement drag washer, or any drag washer for that matter, be soaked in oil or greased before installing it? I'm a little nervous about removing the shaft sleeve retaining pin. But the shaft looks like it has plenty of grease on it where it goes into the bearing retaining plate. Did you hammer the pin out? also , the shaft has a washer that sits between the spool and the gear on the shaft that looked kind of funky when I took the spool of. do you recommend replacing it? (see Picture)Thank you.

Chuck...the drag washer seems to be fine to me...this reel never seemed to be beefy enough to be pushed very hard...I never felt the need to replace it...the sleeve pin will push out with a small punch or nail...it only goes one way...if you have to force it push the other way....grease should be put everywhere on the drags.....hope this helps....if you have anymore questions please ask....Bill

I have fished my Diawa DF-100 a lot over the last year or so. I put in a carbon fiber drag washer, it is a Penn HT-100 but I don't remember which one, with Shimano drag grease. I replaced the fiber washer you mentioned with a washer I cut from HT-100 with drag grease and I greased everything else with marine grease. This reel has held up really well, I fish it with 30 pound line and absolutely love wading into the surf with it, zero bearings to worry about. I may someday spring for one of Alan's handles but that is a bunch of coin for a reel like this.

There is one bearing that if you dunk your reel in the surf and don't clean it properly will go bad on you. 30 # line and 10# of drag and you can't go wrong with this reel, I have caught many Blackfin tuna, Amberjack, sharks and catfish with mine. The biggest fish so far with it is a 120# Bull shark that fought for about 45 minutes.

Thanks guys. I have some more questions but I'm gonna wait till the replacement washers get here. Daiwa is sending replacements and I ordered some Penn HT-100 drag washers from eBay. I need to get this reel in top notch condition for my trip to Costa Rica. I got a date with some Rooster fish down there.

Sorry, forgot the "A" has a bearing. The non A doesn't.

Hello to all,
I am planning to buy that reel from Ebay and wonder if anyone solved a problem with the ugly noise????

Second question:
Does that reel have enough drag power to handle with the fish up to 18KG (39LB)?
Thanks.

Here is an ADDITION to this thread . . .

I found another tutorial on a Polish website, where ADDITIONAL BEARINGS and other MODS were done to the DAIWA DF-100A GIANT.
