Hello Does anyone know the size of wheel bearing my bass tracker 17' pro trailer has it is the original trailer that came with the boat new. To grease the bearings do the dust covers have to be removed to get to the grease zerts. Thanks.

Re: Trailer bearings

Hi,
Most trailer bearing sizes are the same. Don't just take off the dust covers to grease them. Take the hub apart, replace the bearings and use a premium WATERPROOF grease. I use Timken bearings and Krazy Grease. Timken bearings are the best and Krazy Grease is the absolute best waterproof bearing grease on the market. Make sure you pack the bearings good. Spending $30.00 on new bearings and grease will save you in the long run from replacing your tires on the side of the road.

Re: Trailer bearings

I was just wondering on the size so I could pick them up to have them just in case. I believe the bearings are good. To check do I have to just jack the tire off the ground and check for noise or wobble or other signs of problems. Going on a long run and just want to make sure that they are ok to travel. The last time I took it to the lake I notice one of the dust covers was missing hope that does not cause a problem. Thanks for the info any other suggestion would be gladly taken.

Re: Trailer bearings

With no load on the wheel simply spinning it will not identify a bad bearing -- it can but it generally doesn't. Some axles have grease ZERKS (not ZERTS) but many do not. For those that don't you remove the wheel and hub, remove the rear seal, remove the bearings and then clean them up. You inspect them carefully for pitting, scoring, crazing or other damage. You inspect both the rollers and the races. If they are ok, you "pack them". If you don't know what that means you can google or yahoo search for the procedure. If the bearings and/or races are bad you drive out the old races and press in new ones. The races, bearings and seals all have numbers on them. Any auto store can cross reference them for you. When replacing the wheel and hub, preload adjustment is essential. Do it wrong and you will be sitting along side the road. Know what you are doing or have someone do it for you.

Re: Trailer bearings

angler, go ahead and get into your hubs. It's not that difficult and you'll benefit in all sorts of ways. First, you'll learn exactly what size bearings you have. Second, you'll see for sure with your own peepers what condition everything is in. Third, if you ever have to perform emergency surgery on the road it will be much easier if you're familiar with your setup. Here's my SOP. Feel free to modify or ignore as you see fit.

Hook the rig up to your TV. Jack up one side of the trailer just high enough that the wheel will spin freely. Crack open a cold one. Spin the wheel with your ear close to the hub just to get an idea of what it sounds like, then remove the dust cap, pull the cotter pin, remove the castle nut, washer, and outer bearings and place them all on a clean shop towel. Wiggle/pull the wheel until it comes off the spindle. At this point I like to lay down another clean shop towel and sort of bounce the tire/wheel over it until the inner bearing falls out onto it. Once you've done that inspect the inner seal for any leaks and replace if necessary.

Next, remove as much of the old grease as possible, then repack the bearings. There are tools for this, but I just put a glob of grease in my palm and slap the bearing into it while slowly rotating it (bearing) to insure even grease intrusion. Drop the inner bearing back into the race (which will still be inside the hub) and slide the wheel back onto the spindle. Repeat the packing procedure for the outer bearing, then put everything back into place. When tightening the castle nut I like to hand tighten it then snug it down a little more with a wrench or channellocks just to be sure everything is seated properly, then I back it off until there's a tiny bit of play in the wheel. Put the cotter pin back, give the wheel a spin to be sure everything's free and easy, then replace the dust cap, apply the grease gun to the zerk, and fill 'er up.

If you have bearing buddies stop pumping when the spring loaded plate (you'll recognize it if you don't already know what I'm referring to) almost reaches the outside of the cavity, otherwise you'll blow the inner seal and lose grease as you travel. You know what that means.:eek::facepalm::mad: If you have the sure lube type configuration (zerk on the end of the spindle) pump away until grease oozes out the front of the cavity. That's pretty much it. Sorry for the info overload, but I'd rather overload than underload you.;) Good luck and welcome to iboats.:cool:

Re: Trailer bearings

One thing to keep in mind when inspecting the bearings. Trailer bearings are the "cup and cone" type. This consists of a tapered roller bearing assembly (cone) and a race that the bearing assembly sits in (cup). If there is pitting or wear on either one be sure to replace the whole bearing set. Do not mix a bad cup with a new cone and vice versa.

Re: Trailer bearings

Thanks for all the help. These spindles do have grease zerks on the ends of them. I checked them all out and with all the info that I got from all of you I think I am in good shape. And :) (Incoop) there is never to much info and I thank you for that any overload is very appreciated. Ice cream sounds tasty. Thanks to all.
