What is the proper procedure to grease the hubs?
Details for first time greasing and subsequent service would be appreciated. Thanks!
-
DirtyGermanAZ· 5 years ago
Axle hubs are almost always contaminated with casting sand. Use a nylon rotary brush and soapy water to wash the inside of the hub. Rise throughly with clean water. Let dry throughly. Use light oil to coat the inside of the hub and pack with 1/4" of high temperature axle bearing grease Synthetic Multi-Purpose Grease NLGI #2. This post is based upon personal experience putting together a trailer like this.

bearings are loose and pre packed. You can add more grease before assembly if you want. Afterward there are zerk fittings in the hubs to maintain the grease.
Helpful?
-
UltraTowExpert13· 8 years ago
There are grease fittings on the back of each of the hubs. The bearings should be manually repacked every 2000-3000 miles or yearly and this may require taking the trailer to a qualified technician.

Do the aluminum surfaces have a protective coating
Aluminum may not rust, but it will corrode.
There is an assortment of protective coatings typically applied to aluminum i.e. Alodine, Anodize, Hard Anodize, paint, epoxy Powder Coat.
Is anything used for surface protection on the aluminum portions of this product?
What about the steel axle? Does it have a protective coating?
thanks,-
dukehamm· 6 years ago
The axle is painted, looks like powder coat, same as all other steel pieces of the kit. It is a "U" channel, not solid/enclosed tube.

UltraTowExpert· 7 years ago
This Ultra-Tow Folding Aluminum Utility Trailer is brushed aluminum. There is no surface protection, as aluminum will not react with water (rain or sea). The axle is black powder coated.

How do the hinged lock together to keep the trailer from folding during driving?
-
Bajafrenzy· 7 years ago
It bolts to the support frame. To make it quick action, I use a quick release pin so set up/take down time is faster. Even if you forget to put the bolt/pin in, it still wouldn't fold up on itself though.

Two hitch pins and clips are used to lock the trailer in the towing position.

Can I use this for my jetski?
Can it be fitted with a winch and bunks so I can trailer my jetski with it?

The trailer is not designed to be used for a jet ski application. We do offer the item number 37554 for a jet ski or personal watercraft.

What is the width of the Coupler Base?
I'm looking to upgrade the standard coupler to a 2" version since every other trailer I have uses a 2" ball.
-
UltraTowExpert11· 3 years ago
The coupler base measures 2-1/2 inches wide. The item number 605644 will be a 2 inch ball coupler that will fit a 2 1/2" wide base.

GumpaD· 7 years ago
That is one of the enhancement I made to mine for the same reason. Northern sells the coupler to fit this trailer (2 1/2" channel), but holes to mount the 2" coupler don't match the holes for the 1 7/8" coupler. You will have to drill 2 new holes. I highly recommend using a drill press. The steel is pretty thick (as it should be).
