new guy - new / old machine

[ivaada]

as always,,, thanks all for the guidance, and keeping me running straight down the road..
I learn a lot from every reply.
.
i need to move forward and try different fixes and not be locked down with "paperwork".
to that end... my next move is to buy a bearing kit....555074
.
and yes i was wrong,,i rechecked and there is not a slot for a c-clip on the inner side.. good call !
who knows what the PO did ?
.
and the question of the day...
does the new bearing kit come with bolts, or do they work with the existing...mine are 1/4 x 20.

[ivaada]

And,,,, I am still puzzled by the "shoulder screws"..54,61,105.
in my exploded view, the head appears to be larger than the screw shoulder or diameter, and also does not show a c-clip and washer on the head end.
and are they 1/4 20's ?
.
on my 505641, the bearing slips off the screw head end, and is held on by c-clips,, again, which my drawing does not show.
.
can this be explained ?
do i have the wrong drawing?

Items 54, 61, 105 are all the same PN, 514008. The shoulder screw head (3/8") is larger than the shoulder (7mm) which is larger than the threads (1/4-20). (Measurements from a '92 BS.) The picture of the 555074 kit indicates it comes with three bolts, four bearings, three lock washers, and two flat washers or shims. Everything except the flat washers looks like what I have. I don't know where flat washers go, maybe those should be nuts.(?) To confirm content I suggest calling SS CS. Two of the bearings are thinner and are used together for the auto-track for the upper wheel.

The notes for the kit also indicate it became standard after SN 97932. Yours is before that, the one I'm looking at is after. I think you are fine ordering the kit, though I'd confirm the content first. If it does not include the nuts (58 in the drawing) they are standard 1-4-20, probably what you already have, used on the auto-track only. Just confirm you have bracket 57 that it mounts to.

ivaada,

With the change to the newer bearings for the auto tracking and guides there were changes with the related parts too. No more "E" clips. As shown in the link below the Back-up Roller Retrofit kit contains everything needed to replace the old rollers and mount them. You will use the existing nuts and mounting holes in your Bandsaw. After the upgrade it will end up looking like the current parts diagram for the auto tracking and guide bearings. Installation instructions come with the kit.

The installation is fairly simple. After removing the old auto tracking and guide roller assemblies proceed as follows.

For the auto tracking put 2 bearings on the shoulder bolt followed by a lock washer and one of the original nuts. Tighten the nut and place through the hole in the bracket. Add the second nut and tighten.

For the guides put a flat washer on the shoulder bolt followed by a bearing and lock washer. Thread assemblies into the mounting holes on the upper and lower Blade Guides and tighten. On the upper guide the exposed end of the shoulder bolt will have the nut that helps hold the blade guard in place just like before.

Follow with an alignment of the auto tracking and guides.

Okay, I'm confused. But I already was. I don't see the flat washer on the current parts diagram nor on actual hardware. But I do see them in the pictures of the kit. I guess if they are exactly the right size it's no harm, but they need to contact only the inner race of the bearing. Has the bearing width changed, necessitating the washer?

David,

You are correct! The current exploded parts diagram at the link below does not show the flat washers. Only the lock washers are shown there. The instructions that come with the Back-up Roller Retrofit kit does show them going on the shoulder bolt/screw before the bearing for the upper and lower guides. All the copies of those instructions I have are dated 9/84. Interestingly my 2006 Bandsaw does not have the flat washers just like the parts diagram linked below. I guess it is safe to say that the flat washers can be used on the upper and lower guides but are not necessary. A flat washer is not used for the Auto-track Roller Bearing assembly.

The use of the flat washer will not change the position of the bearing.

found it,,,
the attached parts layout shows how the roller bearing on my old 1983 saw really are... the slotted screw with c-clips on both sides of the bearing.
found this is a Magna model 630 manual. Anyone know the year Magna became Shopsmith ?

"magna" to yuba to magna american to ss inc to rlf to rlf...

I leave for others to fill in the dates.

[chapmanruss]

When the Bandsaw came out the company was Magna Power Tool Corporation, but the original Magna Engineering Corporation was still there it is just that Magna divided into two divisions. Magna was bought by Yuba Consolidated Industries and they formed Yuba Power Products in 1958 along with another company they had bought. Yuba sold the Shopsmith/Magna line and it became Magna American Corporation in the early 1960's. After dwindling sales Magna American ceased production in the later 1960's. In 1972 Shopsmith Inc. was formed and restarted production and sales of the Shopsmith Mark 5 and the related Magna SPT's like your Bandsaw. Although still commonly referred to as Shopsmith it is now RLFBrands LLC since 2010 and for a short time between was RLFShop.

Because they were rollers the "E" clips were use to hold the position of the roller on the screw and allow the screw to be tightened on the guide assemblies without tightening against the roller. The upgrade is a much simpler system.
