G'Day,

Well stone me! Just got back on the road after my rear hub incident. Gave the bike a good wash and went for a couple of short rides to check everything out as detailed in my last post. Had noticed a couple of black streaks on the swing arm that I took to be burnt on oil from when the hub shit itself.

Anyway when I was checking it all out I noticed more spots all over the same area. Scrubbed away with degreaser, polish, brasso etc. and they wouldn't move, just took the paint off.

Thought it was an odd spot for chain lube to flick to and what the fuck was in the lube anyway. Looked up to find a small hole in the edge of the battery container underneath the seat. Poked it with my finger and the hole got bigger. Yep, it was battery acid doing the damage.

The battery had been leaking through the seam where the top joins the body. Supposedly a gel battery? Bloke I bought it from had not long put it in as the original died from lack of use.

So beware this brand of battery. Also beware that if a battery does leak (and the battery place says it doesn't happen with gel (?)) then the plastic tray is no protection. Bubbled away merrily when I neutralized it with bi-carb.

So another thing I can be paranoid about. I've sealed the new battery around the seam with silicon and to make extra sure will make a sealed stainless steel tray for the battery to sit in.

Paint code is 'C' according to the plate on the frame. Anyone know where I can get touch up paint for the swing arm?

Cheers

Deano:blah:

Hey Deano.

I had this happen to me twice.

Once with my Brute 750S back in 2005. Swingarm was replaced under warranty by the then importer Paul Feeney, though I had to ship the bike from Sydney to the Gold Coast at my expense.

And again two months ago on my 910R after a new gel battery had been fitted at service time. It took a while but the battery manufacturer eventually accepted liability, after the faulty thing had been sent to the factory via the local rep and importer. In the end I had the swingarm pulled out, resprayed and refitted at no cost to me. The boys at Motorcycle Weaponry did all the work and chasing for me. I only just got the bike back three weeks ago. The damage was bad but not as extensive as that in your pix.

Unfortunately I don't think you can touch this up. You probably need to have the whole swingarm resprayed. Acid and magnesium don't mix very well.

Cheers mate.

You just keep hitting the jackpot mate, so sorry to hear, so I gather you had the alternator repaired, did you check to see if it's charging correctly and not cooking your battery.
I would have replaced the battery with a new non lead-acid style battery like a Shorai LiFe

or a Ballistic job

I think it's really worth looking into the new battery battery technology, there are a few guys on the forum already running these with great success.

BTW, the swing-arm is Alluminium alloy not Magnesium.

Donsy,

Yeah, must have kicked a Chinaman (apologies to our Asian cousins). Checked the output at 14.7 volts which seems to be about right (I hope). First thing I did as I cooked a zillion batteries on my Sportster over the years. Harley had trouble working out what a regulator was 'sposed to do. About the same as their concept of brakes.

I will definitely investigate these batteries you mention.

Thanks mate.

Cheers

Deano

What a heartbreaker... Makes my decision to go with Shorai in the MV and Duc seem like an even better decision.

I hope that mess gets sorted!

A properly serviced (and manufactured!!!) AGM (absorbed glass mat....not really gel) battery will not leak acid. There should be no loose fluid in the case.....however!! if the battery is overfilled, or is charged initially with the wrong type charger (high amperage) then the plates can not absorb all the acid. The fact the case separated is a clear indication this battery was defectively manufactured....I'd try and get the company that sold it to pay. Battery acid does make a mess, doesn't it? But should not have damaged the plastic!!!! What the hell kind of acid did those Chinese use?
