Gears are often press-fitted onto shafts. You
get them off with a gear puller.

I found that there were two cap screws holding it on, once they were removed came right off. Now to find the solution to replace the right angle gear assembly as a whole, like either a gear box, or some other route. Anything has to be cheaper than a machine replacement. Thanks Loren.

Replacement parts found, digging through interweb and half a day later found the solution on LJ’s. Renova still carries steel replacement gears for this. Not cheap, but much cheaper than throwing away a useful tool.

there is a pin in the gear, drive it out and push gear off.

there is a thread on here somewhere, in regards to this fix, as the new metal gears are very expensive, i attempted to adapt a off shelf gear from a local co. and couldnl’t get the correct size, gearing, angle ect.

so i opted to move the belt and gearing up on top of stand, see the thread if you can find, i’ll try, but am terrible with this kinda stuff.
anyway, it makes the unit functional, just have to address height issue with either vice grips or channel locks, been using mine like this for a year or so, little tedious at times, but it works.

i just get pizzed off at the feed belt not staying centered, have to adjust regularly
good luck

$158 is obscene for a couple gears that should be more like $25 for the pair from a high margin supplier like McMaster or Grainger.

Knockonit, I just bit the bullet and spent the money on the metal gears. I know they are outlandishly expensive, but they are cut and drilled to fit exact, so I went with it. To replace the machine would be $1400 for Supermax or $900 for Grizzly. So for a little under $200 I justtified keeping what i have. I did see your approach and wondered if you couldn’t adapt one of those closed end ratchet wrenches to replace your visegrip. Seemed like a lot of work to flip everything around, and my time in the shop is limited by my time at work, so had to go the quick fix route. Did get all the gears off, so now waiting for the parts to arrive.

Thanks for the reply.

I wrestled with the thought of paying 158.00 for a gear so I laid underneath for a while and tooled around and came up with a simple solution. disconnect the elevation shaft from the right side of the machine which meshes with the gears get rid of it. get a 1 1/8 wrench and raise the table by turning one nut ( 1 of 4 ) one on of the elevation columns . a little slow for now but works fine and bypasses those gears. or you can unscrew the two small screws and drop the gear and fabricate a handle and crank that you can screw onto that mechanism. or get a ratcheting wrench to fit the large nut. I am good for now to get my project finished but still thinking of a wat to make it quicker.

it was a great sander, but eventually i came across a performax 16/32 at an awesome price with stand and lotsa extras and just bought it, and did fend this off on another woodworker in the east valley, who really enjoys the useful remedial set up, he is aware of the opportunity to buy the gears but has opted to modify my approach some and uses a rachet type wrench. says it takes some getting used to, but serves the purpose

i do love my drum sander. makes life so much easier

Search “Delta 18-36 Sander Owners…..A Must Read ” on Sawmill Creek.
Gears are available from Boston Gear for about $30 for the pair.
