Has anyone on here every replaced the bearings on a beacon star 10" or 14" slab saw? looking for advice and any information would be helpful. It looks to me like the bearings are pressed in and would maybe require a puller and maybe a press to re-seat the new ones?. Diamond pacific still makes this same saw now labeled as the TC14 shown in the picture below. Chuck

Fastest way to find out would be to call Don Depue at DP and ask. If you can get the old bearings out they probably have numbers on them and would be available through a bearing house like King or Kaman. If they are pressed in probably any automotive or other machine shop could help you out.

thanks John. I thought about calling them but having a contact name sure helps. I was hoping someone on here has actually done it to know what kind of job I am in for before I go for it.

Some bearing housings like that are "water pump bearings" and are pressed on the shaft. You drive entire shaft and bearings out and replace as a unit. Gy-Roc saws are like that. BD uses something similar on their now obsolete BD6 and PF10 (same part). They sell the entire housing, shaft, bearings, nut and flanges. Your housing looks like it is cast into the table?

nope not cast into the table. The blade,bearing housing,shaft and pulley all come off with (4) screws. Actually that's how you have to change the blade too. Chuck

If you strike out with DP unbolt the housing and take it to a bearing house. How long is the housing and overall shaft length? 5/8" shaft?

If the housing is 8" long, shaft 12-1/2", bolt holes 5-1/4" side to side and 3-1/4" across I have one. 5/8" shaft, RH threads. It was on a home made sander I found at a yard sale. I don't know what it came off of originally. I was going to haul it to Quartzsite along with a big box of other treasures. Pretty cheap if you can use it. PM me if interested.

So far I have been able to disassemble that style of housing with a dead blow hammer and brass drift. The bearings should have part numbers but ID, OD and width measurements will get you there too, often for a lot less money.

My Covington saw hs a similar bearing construction and i was hoping that it would last longer than me.That replacement looks like it would require heat.Call Covington to see what they suggest.It's all good advertising for them coming from a discussion forum.They are freindly and helpful everytime.

John- Thanks for the offer but the shaft on mine is 3/4. Plus each saw is factory aligned and then the housing is bolted down with the 4 hex bolts. after that they drill through the bearing housing and table in two spots kitty corner and tap and screw those locations so after that you are not supposed to need to re-align each time you take it apart. that means each housing is unique to that saw at that point.
I do need to call don back to see if the bearings are pressed onto the shaft or not. When I tried to take it apart yesterday it seemed like pounding on the end of the shaft drove the shaft and bearings out of the housing but the bearings never budged from there location on the shaft.
I would like to replace the shaft too while I have it all apart but don gave me a pretty hefty price for that so I might see if I can get it duplicated locally or from the member on here that was offering machine shop service.

Now that you mention it I think BD buys the shaft/bearings as a unit and presses them into the housing. If you can drive yours out take the shaft/bearings to a bearings house and have them order.

i would be more than happy to make you a new shaft if you think you need one it would be about 15 bucks plus shipping.
did you actually get the shaft and bearings out of the housing?...if so im sure we could help you get the bearings off and back on.
if all fails you will probably need to take it to a machine shop....if you dont have 1 close by....or they seem to expensive....if shipping isnt to expensive you could send me the unit and i would help you out...make new shaft....replace bearings for you and reassemble the unit.
everything would run 25.00 bucks...plus my actual cost of bearings...plus shipping both ways.
please let me know if i can be any help...kev.

hey Kev, that sounds like a great offer. I am assuming the bearings are pressed on since this is how the shaft came out. here's a few pictures that show the mess I am in now. If I could send my pile of parts and get back an assembled arbor thats the route I would go for sure. Let me know what you think after seeing the pictures. the bearings are labeled 6204-rs blade end of shaft has a groove for a snap ring that the blade washer tightens against and a snap ring groove at the bearing. pulley end of shaft has no snap ring grooves at all this is the inside of the housing thanks Chuck

your bearings by the photos do appear to have moved off of their fit on the shaft....so it should be easy to get them off....i really dont think you need to send it to me...or take it to someone....go get 2 bearings....those bearing numbers are common bearings....i replace them all the time on customers shafts.
you managed to get it apart....that was the biggest hurdle...get the new bearings...any seals if it had any....we all here can get you thru it....not gonna be hard i dont think...if we cant walk you thru it here...im just a phone call away.....kev.

kev, sounds like you dont want me to send it, lol. The bearings did not budge one bit when I pounded the shaft out. I have no idea what those other lines in the shaft are from. where the bushings are shown right now in the pictures line up perfect with each end of the housing. I pounded on the bearings with with a piece of wood using a 3lb hammer and got no movement. Do auto stores have a tool for removing them and reinstalling them?
thanks for all your help Chuck

most bearings on arbors are press fit but a tube just longer than the shaft will push them off = a little to a lot of fitting tool help will be needed (of course after the retaining clip/rings are removed) and put back on the same way. Most have just ceased and just need to be listened

Thanks for everybodys help and engorgement on this project. I took the shaft and bearings to nice small family owned auto parts store and they pressed the old ones off and new ones on for $20. Now here's the kicker, it turns out that the bearings must have already been going bad when I bought the saw and must have just went real bad recently because this thing is almost silent when its turned on now. It had always been loud but it was my first saw so I thought it was normal. So we are back to cutting again!
Thanks chuck
