saluate.dat fiind faptul ca a venit primavara si motorul meu are vopseaua cam decolorata m-am gandit sa ii trag o vopsea noua.La demontare am constatat ca am multa mizerie in rezervor.cum o pot elimina ?am auzit de faza cu lantul in rezervor dar ma gandesc sa nu imi faca vreo bucurie la sonda si sa ma trezesc cu ``punctari`` prin tabla.multumesc anticipat pentru sfaturi

deci ...e semirecomandabil cu lantu-- daca e tabla subtire si lantu prea mare si tu prea vanjos ......il poti ....indoii

..... poti incerca cu jet de apa sub presiune ...*(spalatorie auto)

 

 

eu unul am bagat lantu in rezervor am clatit ...cu benzina ...dar fara mare efect ..... a curs dar nu tot.... oricum a luat jegu de 40 de ani ..din rezervoru de festival....

 

apoi am spalat cu detergent de vase ..... pt ... degresare ..... am clatit f bine apoi cu apa.... (la spalatorie auto) ...

 

apoi am bagat OTET .. am lasat peste zi si noapte ... apoi am scurs ... .... (poti incerca acid clorhidric (muriatic) sau solutii spciale ..dar mai rare pe la noi)

ideea e ca dupa ce bagi OTET ...sau un alt acid... tre sa il stopezi cu ... bicarbonat ... ala de baga mama la prajituri ....

apoi iar speli f bine......

 

dupa ce faci pasu asta ..... ca sa elimini si bicarbonatu iar speli f biiiiine .....

 

il usuci cu ce poti cat mai repede .... si il umplii cu benzina ..ca apoi iar ...corodeaza....

 

daca ai ...indicator de nivel in rezervor ...scoatel inainte sa .... faci vre o treaba ...dinasta ....

Parerea mea e ca te maninca in fund. Lant in rezervor, acid clorhidric... De fapt, cu ce te deranjeaza mizeria aia?

 

 

 

pai imi murdareste filtrele si imi intra in carburator

daca ii infunda decantoru ala ..de pe rezervor ...ce sa mai curga ,,,, in filtru???

 

de scanteie ...nici nu e vorba ..... eu n am auzit la nimeni ....

 

3.... OTET simerge ca uns.... 20 de lei sticla ...

Mai bine motorina,cu benzina su totodata cu lantul se poate sa faca vreo scanteie !!

In atmosfera aia saturata de vapori de benzina, poti trage si cu tunul!

Ia gandeste-te putin la contactul becului "rosu" din rezervor sau la pompele de benzina imersate in rezervor, care nu sunt altceva decat motoare electrice de curent continuu care au carbuni si perii colectoare.

P.S. 1 Asta suna la fel ca si mitul aparatului de radio aruncat in piscina sau in cada, mit intalnit in filme.....

P.S. 2 Daca taceai.....

Sau mitul chistocului de tigara aruncat in benzina....

 

Tigara se stinge cand o inmoi in benzina... :angry:

Am si eu o intrebare mai naiva: rezervoarele se curata periodic si la masini? Ma gindesc la ce tre' sa fie intr-un rezervor de masina, masina care in medie vede mult mai multi kilometri decit un motor.

Nu cred ca se pune problema in functie de numarul de kilometri.

Cred ca mai mult conteaza cat timp "zace", in special daca e vorba de un rezervor metalic.

Hi

 

I have a 1989 R100GS that I have owned for the last 15 years. I have been having problems with the inside of the tank rusting. On a test ride after a carb rebuild to check out my beautifully synchronised carbs I had to switch to reserve and the resulting flood of rust and crud blocked the inline fuel filters and the bike limped home. I decided to give the inside of the tank some serious attention.

 

After research on the web I decided to clean the inside of the tank using electrolysis, and then seal the inside of the tank using POR15.

 

Here is the inside of the tank after draining it, removing it from the bike and rinsing it with a garden hose.

 

 

 

To carry out electrolysis on a rusty tank you need a sacrificial anode. You apply a positive voltage to this and a negative voltage to the tank. The anode gets eaten away during the process. You need to ensure that the anode and the cable going to it cannot touch the tank. I chose to use a broken long power screwdriver blade held in a plastic funnel as my anode.

 

 

 

I filled the tank with warm water with laudry soda in it and then inserted the anode. The power supply was a 12V battery charger. I left the petcocks on the tank. Once I urned on the power to the charger the initial current was about 1A indicating considerable chemical activity, but this soon drops as the anode gets surrounded by chemical sludge and the water inside the tank cools.

 

 

 

I initially left the process for 4 hours. I then turned off the power drained the tank and rinsed it out with a garden hose. A considerable amount of the original reddish brown paint came out together with very brown water.

 

I repeated the process several times. Here I have a ring of bluetack around the petrol cap opening so that the cap fittings get cleaned. You can also see the very dark colour of the water after a lengthy period of electrolysis.

 

 

 

When the anode is removed from the tank after each period of electrolysis it is surrounded by a green foam and when this is cleaned off you find the anode severely eaten away.

 

 

 

I repeated this process several times. Once I rinsed and shook out several largish chunks of what looked like soft red sandstone. I dont know if they were products of the electrolysis, or the results of years of petrol additives. Here is the inside of the tank after a thorough rinsing partway through the process.

 

 

 

I repeated the process until when I rinsed the tank I only got a few bits of paint out and I could not see any obvious rust. The water was still dirty though but this could well be due to chemical products produced during the electrolysis. Here is the result.

 

 

 

I bought a POR15 Motorcycle petrol tank repair kit. You need to add another can of petrol tank sealer as the R100GS has a large tank. I then followed the POR15 tank repair process. The first step is to clean the tank with Marine Clean an industrial strength degreaser and then rinse it. The next step is to etch the inside with Metal Ready. This neutralises the rust, etches the inside of the tank and acidifies the surface so the POR sealer sticks.

 

Here is the result, ready for sealing.

 

 

 

The POR15 sealer has the colour and consistency of silver hammerite. The final step is to block the petcock holes, pour the sealer into the tank and slosh it around to cover the inside of the tank and then let excess sealer drain out through the petcock holes. I used a plastic emergy fuel cap to block the filler hole which worked very well. This turns out to be quite difficult as the large and strange shape of the R100GS tank means some parts of the tank cannot be coated this way. I had to resort to a long artists paintbrush to get some parts of the tank covered.

 

The sealer is then left for 96 hours to cure. Here is the final result.

 

 

 

If you are thinking of doing your tank this way a few words of warning. 1 Electrolysis generates small amounts of hydrogen an extremely flammable gas. 2 The tank must be negative and the sacrificial anode positive 3 If I was doing it again I would leave the petcocks on during the degreasing and eching processes 4. POR15 tank cleaner sticks to everything, sets like iron and doesnt appear to be effected by any solvent I have access to so wear gloves and take extreme precautions again spillage. 5. The tank will drip sealer for hours so mount it securely with the petcock holes at the lowest point and with the petcock threads protected by tape and drain into containers you will throw away.

 

Steve

daca bagi lantul in 2 luni arunci rezervorul ca rugineste de tot .......se sableaza apoi se face tratament

treaba asta se face in functie de mediu ( daca e mult praf sau nisip ) de calitatea carburantului sau de materialul din care e facut rezervorul

referitor la ce au zis :

p.c. .....treaba cu electroliza e ingenioasa !!!!

survolaj ....merge incercat si cu gaz .....oare ofera si o protectie antirugina pe cateva uni acolo ???

oricum ideea era sa nu bagi lantul ca in cateva luni iti rugineste de tot !!!
