I thought I would chronicle assembly of the G0490 and installation of the Byrd Shelix cutter head to document any issues and solutions.
In this first pic I have unbolted the motor from its shipping location and mounted it onto the motor bracket inside the cabinet. I also installed the dust collector outlet and mobile base lift wheel. I got the beast up on the stand with the Kubota tractor, its not a one man job without a hoist or method of lifting it.
Issue #1 – Hand space is cramped around dust collector sheet metal when installing the 8 bolts to hold the jointer to the stand. Plus you can only get about a 1/8 turn on some of them with an Allen wrench. Recommend a long extension and Allen head socket for this job as ideal, I made due with a long screw driver to get the bolts snug then a short Allen wrench and suffered through the 1/8 turns.
Here I have removed the straight knife cutter head, I backed off the table stops and lowered both tables to maximum, the 4 bolts were not very tight in fact I found a number of fasteners that were not very tight so I’ll be checking them all as I go. The cutter head came right out with no issues.
Here is my victory picture, the bearings and these cast iron blocks have been successfully removed from the old straight knife cutter head and installed on the new Byrd Shelix cutter head. It was not without drama however.
Issue #2 – Pay no attention to the instructions, you can’t tap these bearings off the old straight knife cutter head with a dead blow hammer and block of wood. The narrow left green cast iron block tapped right off without much effort…leaving the bearing still firmly attached to the cutter head shaft. The right one would not budge, note the bearing in the right wider cast iron block is held in place with a snap ring on the inside of the block.
A trip to Harbor Freight and I’m now the proud owner of a 12 ton hydraulic press. I used some scrap lumber to make a box for the cutter head (4 sides and a bottom nothing fancy) so it would stand up straight on the hydraulic press and drop onto the block of wood as I pressed the bearings off the straight knife cutter head. First up was the wider right hand cast iron block and bearing, it went BANG!! when it let loose no way it was going to be hammered off as per the instructions.
Issue #3 – The left side narrow cast iron block tapped off the bearing easily but there’s a problem. The bearing is firmly pressed onto the shaft and there is not much room behind that bearing to get old of it. Maybe they make a gear/bearing puller that’s small enough I don’t know but you have to get under the inside bearing race and apply force there so you don’t ruin the bearing. There’s only about 3/16” of space. I happened to have 2 thin box end wrenches for getting into narrow spaces that were about 3/16” inch thick, I sandwiched the bearing between them and used the press to pop the bearing off. The press had bent the wrenches significantly before it cut loose with a BANG!! that’s how tight it was on there.
Re-installing the bearings was straight forward though I used anti-seize as the factory should have. The left bearing was easy using a socket, I used a 3.5 inch piece of black iron pipe filed flat to seat the right bearing/cast iron block as the shaft sticks out a couple inches for the pulley. Speaking of which the bolt holding the pulley on was fairly loose and I read about a couple instances where peoples pulleys had fallen off. I may put some blue Locktite on that bolt holding it on. NOTE: The left and right bearings are two different sizes.
Tomorrow I’ll continue with the assembly and cleaning.
