How to Replace a Bandwheel Bearing - Wood Mizer LT40

I had replace the bandwheel bearing on the wood mizer lt40 sawmill after it began to howl! This is how I did it.
Doing your own maintenance on the wood mizer lt40 is just part of running a portable sawmill business and this was my first band wheel bearing that went bad so I had to replace it. I didn't see many videos on how to replace it so I made this one for anyone in the same situation as I was! Hope it helps someone.
Here is a link where I found several of these bearings:
www.bdiexpress...
The Koyo 5309 was the recommended bearing at a good price and I see them here at $119.45 however they list several alternatives including the Timken at $177.00
Amazon also has alternatives but I don't think I'd use those bearings as quality is important on a sawmill! I'll be ordering a Koyo since the Machine Shop thought they were a good alternative that wasn't 5 times the cost of the Wood-Mizer Peer bearing.

Check out some of the things I use in my daily work on the sawmill (or in editing these videos and making them). Thanks!

And you laugh at me over a few (or many) toe board incidents. This video was very informative. Thanks, Dic.......I mean Erik. Bad Dave

[@TheOldJarhead]

lol oh you don't know the half of it!

[@MsdMakingSawDust]

I like that one !!!!

Those bearing are a close/tight tolerance press fit in the wheel hub. anti-seize would have done NOTHING to help. You can warm (200-300F) the wheel hub up and sometimes drive them out, and it makes it easier to press them in. You can use a couple c-clamps and pieces of angle iron to clamp together and push the bearing in, then use a spacer between the bearing and the angle, so you can keep pushing the bearing in. it also helps if you install the retaining ring and push the bearing to the ring, unless there is a lip on the hub that the bearing seats against in the hub. in that case, you just push the bearing in till it seats against that lip. as for the amount of slease you used on the idle shaft, yea, you used WAY to much. a little, as you said, goes a LONG way. as for the torque on the bolt allen head bolt, 150 should be inch lbs, NOT ft pound for that size bolt. im sure there is a standard torque chart for bolts on google, BUT!!!!!, there is a tq chart in the lt40 parts manual for your year model, page 6, and item 5 on page 20, 3/8-16 which is 40 ft lbs, or 480 inlbs (40x12=480). gorilla torqing things on like that will only lead to threads being stretched and material fatigue, which could lead to failure at the most inop time (in the field)

Thanks! Great info!

I was hoping it was like my older LT30 with pillow block bearings on the back side of the wheel. Mine are starting to sound like gravel :/

[@TheOldJarhead]

It wasn't too bad ;) The lesson I learned was: take off the wheel, take it to the machine shop, let them deal with it and then take it back and put it on (the right way)!

[@Twobrothersoutdoors]

I'll be a son of a gun, some of my specialty tools end up at auto parts stores or snap on truck

[@TheOldJarhead]

lol yup me too! Good thing they are easy to find that way! ha!

[@Twobrothersoutdoors]

@@TheOldJarhead it's convenient, but the damn storage rate is a killer 😏 using a machine shop when in doubt was probably smart. I imagine fracturing that cast wheel wouldn't be too hard. Good video!

[@TheOldJarhead]

Yes the darn storage fees suck! I mean really, I found it there after all! ;) And yes, I was worried about damaging the bandwheel so went with the smart choice! Thanks!

[@davidjohnson145]

So he put the wheel on backwards nice I saw that must’ve pulled a Dave again😂😂😂

[@TheOldJarhead]

hahaha Hey Dave! Different Dave but no, this was all me!

[@DANG--]

It was to dark to see you put it on backwards, could not tell for sure until about 13:47 then I saw it was on backwards. You said that was a wood mizer bearing correct ? Wood Mizer with china bearings? I guess i need to start looking for a replacement that is made in the USA. I have been binge watching your videos, now that i am back from vacation, so I hope i am not to late on the comments. lol

[@TheOldJarhead]

Yup, they use a Chinese Peer bearing. In the description below there is a link to buy better ones. I am not affiliated or sponsored by them, it's just a link I found. And you are always welcome to comment no matter how d the video!

[@TheOldJarhead]

By the way, thanks for binge watching ;)

[@southernadirondackoutdoors]

Fun video...for viewers at least! How many hours would you say the old bearing lasted?

[@TheOldJarhead]

lol I'm glad it was amusing lol. The bearing lasted just shy of 600 hrs

[@monspoon]

Thanks! I've been putting this job off for a while. The woodmizer book that came with the mill fell apart at the bindings and is in pieces scattered around our mill, so I was going to get a quick walk through from WM by phone. Rainy day today, so I figured I'd dive in....then found your video which was really helpful. I've replaced the drive wheel bearing, and many other parts....just always hesitant to dig in. We have an electric lt50 with 8000+ hr and a lt40 with almost 12k!

[@TheOldJarhead]

I'm glad you found me and that I could help motivate you! Good luck with the bearing replacement! Some go easier than others! Your mills have a LOT of hours, but that's why I bought my 1st one over 12 years ago! They just keep on milling! Cheers!

[@monspoon]

@@TheOldJarhead ugh stuck on the 7/32 Allen. Buggered up the hole. My machinist friend is on the way. Drive wheel went pretty smooth. We saw salvage old growth redwood, Mcmullin Sawmill. Our WMs are workhorses. Run hard. Thanks again for putting out the helpful vids!

[@TheOldJarhead]

Crap! Hope he can get it sorted. Got a l8nk fir your biz? YT? And thanks! I enjoy helping if I can! Cheers!

[@paulcasefarms9933]

I have a vid on that that I made in 2020 but you do a much better job !!!!

[@TheOldJarhead]

There were two I think or maybe just one I found via search! But thanks! I'll have to go watch yours and see if UT was one if them!

[@paulcasefarms9933]

Turn it around the other side out at 13:20.

[@TheOldJarhead]

Yup! LOL

[@MsdMakingSawDust]

Good video , you got to love them snap rings. Have a automotive shop and replace bearings all the time, I’ve seen some snap rings fly off into the un-none … lol good video Thanks for sharing..

[@TheOldJarhead]

Yes sir those are tough and always a concern lol. Thanks

[@thearrowheadwoodsman3811]

Very good ! I've been frustrated with woodmizer once or twice. Enjoy bourbon:30 Cheers !!

[@TheOldJarhead]

Thanks! They have always been good to me! Bourbon Thirty it is! Cheers

[@johncote8061]

Replaced the band wheel with the back side facing out? I was thinking marking the front of the wheel might have been a good idea before pulling it off. Great video.

[@TheOldJarhead]

Yup! I figured it out as soon as I tried to put the band on lol. Was an easy fix though;)
