New style Haban casters
 

Ok guys need some input here. Any of you rebuild the new style haban front casters? OE wheels look to have bushings and sleeves with 1/2 inch bolts going through. Bushings are 1.382 OD and ID is for 3/4 inch shafts. The OD of the sleeves are .750 and ID is for the 1/2 inch bolts.

Just trying to source this stuff locally without paying an arm and a leg but my local bearing store can't get the bushings. I picked up the right ID OD "wheelbarrow" bearings as they call them which looks like it will work but wondering if they're too light duty to hold up against the mighty Haban.

Wheel bushings look almost exactly like the O front rim ones but ID is different

Thinking about trying to find some pipe to make the sleeves but hoping someone has a source and numbers that have done theirs. I'm re using the wheels btw.

I'd bet that the wheel barrow bearings will work just fine if you keep them greased. Here is a link for some tube that should work for bushings.

If your in a rush you could cut the existing bushings in 1/2 and reinstall them with the worn part to the center.

Thanks for the link Sam. I might just do the cut the sleeve in half method temporarily.

What's the weight rating on those bearings??? That deck is pretty heavy

Alvy,the o.d is the flange?or the where it steps in? If so I have set for you.

You better check the OD. Measure where the bushing fits into the wheel. I'm assuming that it's 1.375". If it is you may want to look at something like this for a bearing and eliminate the spacer.

Any decent welding shop worth it's salt should have bushing stock in various ID's and OD's
Those cheap WB bearings are just that, cheap.
Think you would be much better off w/the higher quality type that are in Cub front wheels.

Look on eBay for sealed bearings. I did that on my Kubota deck that would wear bushings out every 2 years mowing 5-6 acres a week. The Kubota deck is twice as heavy as the Haban and I've not touched it in 7 years. I'll see if I can find what I picked up. The Kubota, Haban and 3000 series wheels are the same.

Where it steps in. Let me know, thanks pal

I believe the problem with using bearings might be that there is a grease fitting in each wheel that sticks in to the bore and the bushings have recesses made into them to go around the fitting so that the wheel can accept grease.

I think you are right about the bearings I got being cheap and won't hold up to the abuse, this one only cuts about 2 acres a week but all year round.

I might go you're route or SAMs route Todd if Lew doesn't have the bushings. These lasted over 1000 hours of use and although the ID is wallered a little they're not bad, the steel bearing sleeve is what really bit the dirt.

Confused why they did over size bushings and a sleeve and not just 1/2 inch ID bearings that ride directly on the bolt but the bolt might put preload on the bushings flange when it gets tightened too. Thanks for all the replies

I have 6 of those wheel barrow style bearings if you want them, $10.00 shipped. Check and see if the grease fitting will clear the bearing, it may be in the hub deep enough to work.

Just had an idea, take the old bearings and have them bored to 1" then use 1" OD X 1/2" ID tube for the spacer/ bushing.

Jeff in PA could do them in a couple minutes.

I'm going to order a set of these for the Haban that I'm doing now.

Well Uncle Lew to the rescue. He had OE bushings and sleeves. I still am in awe of the amount of things he has in his stash. I'm sure he won't mind me saying, price was right on too. Thank you guys for all the advice and brainstorming, I've done a lot of it today as well. Will post back with results when the mailman arrives.

Those are cool Todd and good price. Looks like they're sealed.i actually make it a practice to remove the seals and pack sealed bearings with a special grease we have at work called S350. It's great stuff.

That's a good idea too Sam. I also thought about JEff as well but need the stuff ASAP as the grass in the sunshine state grows at an alarming rate this time of year. Learned a lot from this thread thanks guys.

Well Uncle Alvy,seems things worked out well for you today.
Already to ship out tomorrow.
Just to let you all know the axle bushing on a 82 series steering knuckle is the same,just have to shorten it.
