2008 Shimano Stella SW 5000 HG to PG gear swap question

Rate this topic

14 posts in this topic

I did the gear swap by ordering parts from plat.co.jp and I did the pinion gear, main gear, and idle gear. I DID NOT order the worm gear since based on the USA 2008 Stella SW8000PG and HG schematics, they are the SAME. Now I'm thinking the USA schematic is incorrect. Going to slower gear should require the worm gear to be cut differently and to  go up and down slower to match the lower gear ratio. The reel works fine but when I went to remove line(that was spooled by the HG gear set) and put on new line(with the PG gear set), I noticed that the wraps are wrong and it's missing spots on the spool. I used 10 lb mono and 15 lb mono for backing and both produced the same result. No knot on the spool. Just blue painter's tape so it's not the spool knot causing the issue. BTW plat.co.jp shows a different part number for the worm gear for the 5000SWHG and 5000SWPG.

I think you are correct - part is not the same PG vs HG.

How did you find the schematic on the USA site?

from going over both schematic PG and HG, 

- i think that you did everything correctly, best is to make a quick call to Shimano in California talk to one of the Stella guru ,, ,they will know.

The USA Shimano parts website has the wrong schematics for the 8000 SW(actual PDF said 18000SW). I have the schematics in the box of my USA 5000 SW and mine is 6.2 gear ratio so it's actually the same as a XG JDM model. The JDM HG is 5.7 great ratio. 

 

According to the printed PDF that came with my reel, the USA 8000 SW(5.7) and 8000 SW PG(4.6) use the same worm gear. There is no USA 5000 PG for the 2008 model so I can't look that up directly and compare. I think this is wrong since on plat.co.jp site, they use different part number......but the 5000 XG and HG, 6.2 and 5.7 uses the same worm gear part number!

 

I called Shimano yesterday but their reel service phone number and extension is not working. The main number worked but it failed when you connect to the fishing reel.

 

I tried spooling again yesterday with straight braid and now I'm convinced that I need a worm gear with different cut.

That's not working at all....

The reason I asked about your 5k '08 Stella on the USA website is that I couldnt find ANY 5000 size schematic when I looked. Must open my eyes wider.

Was it with all the other schematics that started with 08 as the prefix? 110 files is a lot to troll through.

Australia site also had no PG for the 08 5k.

At least plat had the correct schemtic.

It's here:

 *

The 2008 model do not have the B or C in it.

 

The 8000 links to the 18000 schematic but if you click download, you will get the right 8000 schematic.

For the B model (2013), Shimano added TWO more idle gears and that somehow was able to reduce the need for different worm gear in the same size but different retrieve speed. Same worm gear for 5 or 6k model and same worm gear in 8 and 10k model regardless of retrieve speed.

 

The idle gear in the 2008 is much simpler. Drive gear mesh with pinion gear which mesh with one idle gear that's locked on top of the worm gear and turns the worm gear which brings the shaft and spool up and down.

 

Looking at plat site for the 2013 B model, the same part number exists across the same size regardless of speed so plat will not randomly put a different part number when it's the same part. So it must mean that Shimano USA website has the wrong part number for the worm gear in the 8000SW and 8000SWPG since they are different on plat site.

Might need to shim the spool up but it's a much better line lay with old gear set. Definitely need different worm gear for the PG set.20200808_170448.jpg.c878378b4106ec105385768dd2e4eb98.jpg20200808_170522.jpg.194f8a9c8cfb59529e0f13f619a86f8d.jpg20200808_170618.jpg.f867bba2f212a7c5a3e8fcd449e9a0bc.jpg20200808_170703.jpg.7ce7e14d6a06b76125adbe97028ad08b.jpg

Finally got the parts from Plat. I'm going to redo the whole tutorial in case I need to do this again. For now here's the difference in the worm gear. Need a thin shim to push the spool up a little bit.

2003 Shimano Stella SW HG to PG gear swap. Need 4 new parts from the PG reel from plat.co.jp site. Basically new drive gear, pinion gear, idle gear AND the worm gear. Without the worm gear, line lay will be horrible.

 

Remove spool, spool shim, and then remove .9mm hex set screw:

20200824_130747.jpg.2b294311ecaf3b6838a18bd144e1fdd4.jpg

 

Set that set aside and remove the rotor by removing the components below. Note all Shimano rotor nut are reverse threaded so CLOCKWISE to LOOSEN! There is a ball bearing inside the rotor nut.

 

20200824_130825.jpg.7acb6c8f64f91a12acdb548d14504841.jpg

 

Unscrew the silver cap counter clockwise:

20170429_135641.jpg.f987395d29ae066a23e9dd24a29a7d6c.jpg

 

Remove that and the parts below it in order:

20200824_130903.jpg.58fc44578f659a2cf9603a5c73bd6990.jpg

 

You will not have that black part that screw into the ARB unless you order an ARB and it will come with that tool which makes life much easier than dealing with tiny springs and block below:

20170117_141259.jpg.2f3ddf72092413d2af3373d19f748c4b.jpg

 

With the ARB tool, simply screw it onto the ARB and lift out unit as a whole:

20200824_125628.jpg.2a7076493db82c8de08bc37d045c0e74.jpg

 

20200824_124829.jpg.00e5488f493ba7e5877220f76d2f665a.jpg

 

Next is the pinion gear retainer. Note the correct orientation:

20200824_130110.jpg.b6c30215b449c2e01e401c32611468e1.jpg

 

The bottom of the ARB must align with those two open holes. The large one and small one.

 

The two small circle on the left at 8 and 10 o'clock in the above picture drops into the large hole and the large single protruding bump at 6 o'clock  drops into the small hole. This is the only way the ARB will engage and be one way!

 

At this point you can continue to remove the pinion gear and bearing or you can skip to the gear box disassemble if you are simply lubing or replacing gear or adding shim. Actually you wouldn't have to go beyond removing the rotor if that is all you want to do.

 

Remove the pinion gear and bearing and remove the bottom cover. Note that there are two screws holding the bottom cover:

 

20200824_134137.jpg.d86d311276b047ad86cdb4ede649d86a.jpg

20200824_130903.jpg.bd0104bf87b0a19b6d8373fe8eaaed60.jpg

 

Now remove the rubber piece that locks the open bail in place and remove the white piece that will reveal two screws for a total of 4 screws that hold the gear box together: Note the white bail trip ramp.

20200824_131022.jpg.e76dea2e53fcdc81e4cf1b8887731f63.jpg

 

Remove drive gear and note that there are bearing and shims on the drive gear.

 

20200824_131222.jpg.f814a5717229024420ba327005c1cd75.jpg

 

You can remove pinion gear if you have not already done so.

Now we will remove the two sliding worm gear support. They are identical in size:

20200824_131313.jpg.fc3aaa6cddafe7e578e4442d8d36d5f9.jpg

Edit : The black spacer shown below is actually installed on the worm gear drive BEFORE putting in the bearing, not after as shown. It is not sandwiched between the plastic and metal piece.

20200824_131431.jpg.387768ed296e6bef3c5e46118e46f2fd.jpg

 

20200824_131501.jpg.a51d2241ae69ae1ee9d0e5398c7f3a39.jpg

 

20200824_131532.jpg.f36786e840c302fb05b3ebd1f4f49971.jpg

Now the main shaft should easily lift out.

Note that the bearing for the worm gear sits flush in the hole so when you swap the worm gear and idle gear, it needs to mate correctly or else it will not sit flush. This will take trial and error by holding and pushing the worm gear while turning the idle gear with a tweezer.

20200824_133225.jpg.f27f288c9edd7d4ea5be129cff55264c.jpg

 

 

 

Oh don't forget the new worm gear needs that little black o ring.

 

20200824_132255.jpg.b6859fd4106a134a3739d7304740b2c7.jpg

 

Drop a little bit of grease on the new components and assemble in reverse. Note the note above for the ARB.

 

Overall picture with parts in the correct order:

 

20200824_131556.jpg.5bebb1fe959502415e341fb8d8b88ee0.jpg

 

Edit: The worm gear bearing spacer goes onto the worm gear BEFORE the bearing. It is not sandwiched between the plastic and matching metal piece that hold the sliding rod that align the mainshaft to the worm gear. Check Schematics. Also there is a bearing that sits on top of the idle gear. It does not go inside the idle gear. It sits in the cavity of the body. I thought I forgot to switch it from the HG idle gear but there is no room for it to fit inside.

Missing a picture showing the bottom of the ARB. And I can't edit my post anymore.

20200824_124721.jpg.92bf01878a64fa9ea5efcc314ac3d33f.jpg

 

Two small circle at 8 and 10 O'Clock goes on to the large hole of the pinion gear retainer. The large bump at 6 O'Clock goes into the small hole of the pinion gear retainer. This is the only way to put the ARB in and make it one way.
