Topic tags/keywords: planer laguna used repair

Hi everyone,
First post – looking forward to hearing some experienced opinions. I got a lead on a used Laguna 20” planer, model number MPLAN2011-0130. 7.5 hp motor. Single phase 220V power. It’s in a different city a few hours away so I can’t go see it in person yet. The guy selling it says the motor is in good shape, but that it needs new cutters and bearings. He’s asking $450 for it. Seems like an amazing price for a machine that retails new for $6,000+.
I can source replacement cutters on my own. I’ve never repaired machinery like that, but am reasonably confident I could figure it out. My question to you is how difficult is it to change out the bearings (and get the parts)? At that price, am I pretty safe?
Thank! :D

I would take it in an instant. Bearings are a cheap, easy fix. Even if you have to hire it. If you were in the Midwest, I would better than double your money on it. It is a great deal. Is the serial number filed off? Ha ha.

Buy it quick!

Have rebuilt a couple of common 15” planers, and one antique 18”. The 15” designs are near identical to the Laguna images I find for the model PN posted (just like most planers).
Bearings are standard metric 6000 series, and easy to find. On 15” model, the cutter head bearings cost me less $20 for a pair of high quality Japanese motor bearing. Less if you want to use cheap chinese bearings, which is probably the reason it needs new ones?
Can replace all 23 bearings on 15” planer rebuild for ~$150. Every rebuild needs a couple other small parts, but as long in-feed and out-feed rollers don’t need replacing, I spent less than $200 to total bearing replacement and rebuild. Any 20” machine for $450 will sell for $1000+ when rebuilt, so hard to lose money even if you have to spend $180 on new rubber out-feed roller?

The only challenge to planer rebuild is weight. To replace bearings you pull the head and gear box. The 15” planers have 3” OD solid steel cutter head, and cast iron box full of gears is all heavy. One person can handle 15”, but a longer head you will want some hep wrestling a 80+ lb assembly out from side of machine.

Changing the cutter head bearing means opening up the gear box, so you will probably need to call Laguna for replacement gasket. They will have expensive bearings too.

If you want to see what’s involved on smaller generic 15”, one of the wood working magazines has several part series on changing 15” planer to shellix cutter head. They show entire tear down and re-assembly. Don’t have time to search it out for you right now.

Best Luck.

That happens when a used tool is priced to sell. Learned the hard way myself. I found a table saw, sent the link to my bro to ask for help loading it, and by the time he got around to taking a look the post was deleted and the saw was sold.

Now i just tell the seller I will take it pending inspection and inform my brother he has to help because ive helped him move like 13 times. Thats gotta be good for at least a half dozen more tool purchases

Have your say...
