Greetings from Spain!
Version: RX (previously called RE)
This trailer has a flushing system, ALKO sealed bearings and spring/shock absorber suspension type.
Despite of this equipment, the owners manual clearly states that the breaks and the hubs cannot be submerged...
I'm not an intensive user, I only use my boat during the summer holidays and in which I put the boat in the water and take it out twice. This means that the breaks and hubs are submersed a total of 4 times per year.
I never carry this operations after a large towing so the hubs are always at a low/proper temperature when they are submersed. Also, I immediately flush the breaks and wash the trailer after I used it. The rest of the year, the trailer and the boat are stored indoors.
Nevertheless I own it for almost 2 years now and I think it is time to do a service or at least to carry a quick check and confirm that everything is in due order.
I've made some research over the internet and mainly in this forum and I learned that:
The ALKO water proof hub caps are difficult to remove and it is recommended to have a former tool.
The waterproof sealed hub caps of my trailer are the following:
ALKO ref.: 1313924
The recommended former tool is the following:
AL KO ref.: 603751
up to here everything is clear, but the problem is that I need to buy the sealed bearing replacement kit (with circlip and one shot nut) but I don't know which is version of AL KO brakes that my trailer has fitted.
I suspect it is the 2051 version but I'm not sure. Perhaps you can identify them from the bellow pictures or you can tell me where to look for a hard stamped number/ref.?
I cannot find the part nr. on the manufacturer's part list because they use their own internal number even for the 3rd maker's parts.
Thank you for your help and regards!
