Exsence dc 17 dc sound gone

Ask them to send the reel to Shimano Japan for you. See if they can handle that.

Funny thing. I just received a Exsence DC to service again. Did it last year and its time again for its routine dissemble...

When you halve the DC unit - the sealed unit is somewhat 'incomplete' from factory. I guess that slipped through QC, howefer this reels gone through some extremely heavy saltwater use and survived for all these years.

When you look at the DC switch mechanism you can see green corrosion this time around. Testament to its engineering I guess - you must've got a dodgy unit otherwise could it be that the internal contact fingers may have worn and not making contact for the unit to work?

She ain't pretty inside mechanically though, let me tell you that...

[Slazmo]

Those contacts and the plate. The fingers are making contact (or should be) between a few plates at any given time so maybe that's your issue?

Thinking out aloud here... Anyone feel free to chime in?

The DC unit shouldn't be disassembled, that's the first issue. As I stated previously there is a sealant applied and once the unit is opened you need to replace it. The stuff we use is something that Japan sends us as we use it on the electric reels as well. It's sort of a silicone based caulking. That is the best way I can describe it. The caulking material is applied by hand to seal this area (or should be) but as we know humans are not perfect. Air bubbles can form if not applied correctly. Too much will cause it to push out of place. Plastic pieces can warp slightly from being removed from molds. Several things come into play here. This is why when we have a reel sent in for a DC issue we typically replace the unit as opening it could cause further issues.

The DC unit in that reel was not designed to handle being submerged, even heavy salt spray is not good for longevity. The only DC unit that is completely sealed is the one in the new Curado DC and SLX DC. My experience with the foreign DC models is limited as we do not sell them in the US. I have extensive experience with our DC units from Calais and CTE since we sold those here and I am the tech that repairs them. The Exsence DC unit is similar to the one used in the Calais. I know that switch area is hard to seal 100% once the unit has been taken apart. It tends to lift a little. I have seen people try and home remedy it with silicone and other things that use the reels for surf casting. They get wrecked and water will get in eventually. I had one customer that continued to have issues so I took apart a new unit and sealed it with the special caulking. He went from sending his reel back every few months to now it's been over a year.

Not all grease is waterproof. Some actually absorb water. However, when it comes to electrical components and contacts you are very limited to what types you can use. A regular dielectric type grease works about the best for corrosion protection and maintaining good contact for electrical needs. Since this is a rotating switch the contacts will rub the grease off to a point so it is never 100% covered. This is why it is mostly used for pin type connections that do not move.

This one sorta has to be, to remove that side plate bearing - that circlip is monumentally hard to undo without sticking a swath of metal probes in there to try to fish it out.

The Exsence and the Calais are different, the Exsence in this case has a coverd* coil, whereas the Calais is what seems to be conforming compound covered as to the OG Calcutta DC. Every now nd again you'll see one with green corrosion on the coils where waters gotten through and started working on the coils.

With that rotary switch, I'll use either lanolin or a silicon grease. Both of which are acceptable for electrical equipment - not too much however both are dielectric and both will protect the electrical contacts and stem corrosion into he future.

thanks guys last few post really were informative and i learned lots of stuff from this topic.

anyway i ordered a new dc module and replaced it , the dc sound is more prominent but still not as good as the day 1.

[Slazmo]

Sounds like you've got a few bearing issues in there from the sound of the raspyness on the video. Or is it just me?

[Mdmel]

Yeah although smooth the sound is a bit harsh aint it ?

[Slazmo]

Yeh get onto replacing those offending bearings and back off the friction knob so that their is a hairs width of side to side play in the spool. From what it looks like the spools not getting enough revolutions too.

[y2k88]

Bit painful to listen to those bearings hahaha.

I like to take the spool out and let everything air dry after fishing salt.
Feels like it's a bit of a usability fail with the way the DC unit is held to the frame with 3 screws, compared to the quick release ones in the past/on some current models.

Probably clean up the spool shaft occasionally because excessive oil on the spool shaft/inside the pinion gear will slow things down too.

[Mdmel]

Thanks guys.

Im not experienced with gear so ill ask a friend of mine to open up the reel and check the internals.

if it is indeed a salt corrhosion problem then im gonna be quite dissappointed.

i used the reel 5-6 times in saltwater and always rinsed with tap water afterwards..

[Bantam1]

Your reel definitely needs some bearings. Probably pinion, X-Ship and the bearing on the spool. With the DC reels if the spool bearings are sluggish or not working properly it can affect the braking. The spool simply cannot spin fast enough to achieve the spool speed that the DC unit is programmed for. Get those replaced and your reel should work correctly.

Be a little more diligent with your cleaning after fishing in saltwater.

[Mdmel]

Thank you for all the positive feedback in tihs topic.

After bearing change on the spool the dc sound is fixed.Im gonna try the hedgehog air ceramic HD bearings in the future but it is fine at the moment.

Here is the pre and post videos of mine incase you wonder ..
