12" Mark V Mounted Planer Woes - Table will not adjust

[charlesteel]

Model 5990 SN 15546
One of the adjustment rods will not turn on my router. I followed the manual but am stuck.
My table does not have four set screws on the bottom. Two of the locations have pins, the other two have nothing.
I'm not sure what to do at this point. I'd hoped to get them free from the table and loosen the one that will not move (and clean all of them).

Any help is greatly appreciated.

More information. Looking "newer"?" planers, I see there are notches cut out of the tops of the Left and Right End frames. Can someone tell me what this material is (cast iron?)? I could drill access holes above the three table adjustment rods and at least be able to move them using the adjustment wheel. C

I would remove the chain and attempt to rotate the lead screws individually. I am guessing that one which is 'stuck' is out of sync. If not, then you can address the misbehaving 'rod' all by itself.

I would NOT do any modifying unless thee fully understands WHY it is not cooperating.

I've removed the chain. Three of the four will turn. The fourth acts like it is frozen. I've moved the other three, attempting to get all in sync with no luck.

I can't get to the top of the lead screws, as the side panels have no access notches.

Not sure top access would help. The sprocket allows applying more torque than the small diameter at the top.

You may need to be more 'aggressive". Try more torque alternating in both directions.

OK, I'll give it another try tomorrow, thanks! I'll need to find something better than needle-nose pliers then. It's so stuck, they pop out of the sprockets.

Finally! I have all four almost completely screwed in (lower the height). Tomorrow I'll make a block and try to dial them in sync. Took a lot of torque to get the one to budge.

Eureka! Bottomed all four sides out, then used a level to get the table as close as possible. All four are moving great now!

Time to shift to the manual and get them all spot on.
