CT235 with tons of corrosion around oil cooler lines and plate under battery

jcims · Aug 20, 2019

Hey folks,

Have a low hour 2011 CT235 that has a problem with creeping corrosion around the plate that the battery sits on and the oil (?) cooler lines that pass through it. I'm not that worried about the battery, but am concerned that I'm going to have an oil leak/dump when those fittings give way. I recall a thread about this from many moons ago (circa 2012 or so), but can't find it.

Does it make sense to replace the fittings going through that 'plate' with something aftermarket? I'm not really worried about the battery itself and I'm assuming that Bobcat hasn't re-engineered this part for better corrosion protection.

Thanks in advance for any suggestions

I changed my stock bobcat battery right away after I noticed it was leaking acid into the battery compartment. Happened mostly when I would get the tractor a A little unlevel.
I caught it before the damage got too bad but it was corroding out the battery tray very quickly.

Clean the area well and spread baking soda around in the area - will help neutralize the acid

Because of someone's suggestion on this forum I bought some of this and put on my connections. I have not had corrosion since. This has been since first week of May, this year. Not that long but it has never taken that long for corrosion to start. NO-OX-ID A-SPECIAL HD Anti Corrosion Antenna Electrical Contact E-Cig Grease NEW | eBay

James (K0UA) told me about it as well, I think 6-7 years ago, I had just changed the original battery and + power cable, purchased the NO-OX and applied it.....
I just checked it a couple days ago, and still no sign of corrosion.

Battery that came with My Kioti CK35 leaked all over the place when mowing started to corrode everything up front. Pulled that piece of junk sanded and painted everything then replaced with a optima red top and haven't had a bit of corrosion since.

When I ordered mine it came in two 8-10 ? Oz cans, doubt I will ever need to order again, maybe my grandson can use the excess up when he inherits my stuff!

Likewise.

I got rid of the wet cell battery and installed an AGM.

Many years ago when my Long 2360 was new and just delivered, I noticed lots of corrosion on the battery support carrier. I treated it and repainted. It continued to rust, and a closer examination revealed the battery was actually split and leaking when it was less than level. So I called the dealer and he sent out a new battery. I cleaned (baking soda) the metal, primed and painted. Before long the second battery got a split near the top of it, and was leaking acid. So this time I grew a brain and measured the charging voltage.. 17 volts. Whoops, that ain't good. I finally found a loose wire on the external voltage regulator (not built into the alternator, like most modern ones will be) and repairs that. So now we put in battery number 3, and measured the voltage, all good at around 14.1, falling thru time to about 13.8 as the battery charged. So I fought the corrosion of the metal battery support plate again and again. Even though no new acid was being dropped on the metal, that stuff soaks into the "rust" and is difficult to neutralize. Finally got it to stabilize and hold paint. A thick plastic battery carrier would have been a great idea. Of course this old Long was a copy of a much earlier Ford design and it was more like a 1950's tractor instead of a 90's tractor.

So yeah the No-Ox-Id will stop the normal corrosion that forms on battery terminals/cables, but If you have a split battery leaking actual fluid out onto your carrier, you have a much larger problem.

I am also still using my original "stock" of No-Ox-Id gleaned from the leftovers of installation of PBX battery systems in the telephone industry. I am down to 2 or 3 ounces maybe now, but will it run out before I "run out"? I don't know. Good stuff, and I have been using it for 40 years.
