I was wondering if anyone would know what the part numbers are for the following bearings?

These seem to be just end open needle bearings.

And these seem to be a similar size but with a seal at one end?

Any help would be appreciated especially if it was an NSK bearing number

TM 9-2320-246-34P shows them to be the same bearing, FSN #3110-975-3586. I use a Timken B-1412. Seals in the steering bellcrank are FSN #2530-697-4249, I don't have a crossover for that.

Got a little done on the 4WS today.

I made a drill template for the holes to mount the steering bellcrank

Image

3 of the holes are 5/16" and one corner is a 3/8"
Drill the first hole and then turn the plate and bolt it on with the first tapped hole. Then drill the rest. I didn't want it to move if I drilled all 4 at once. Also take note that I had to make the plate have 4 pads as the bosses on the trans-axle were a long way from flat.

Image

Image

Image

The rest of the holes worked good with the exception of the angularity on the top ones because the frame tube is in the way. In hindsight if I ever did this again I'd take the frame tube out so it would be a perpendicular shot to the mounting pads

Image

Image

And the mounted bellcrank. Not my best safety wire job but I'll redo it when I tear the whole mule down for it's resto.

Lance, from what I am seeing you will have no issues with the quality of your work on that 4 wheel steer installation.

It's been a while. I overheated and warped/cracked the head on the '43 GPW so I had to teach myself how to weld cast iron and then surface it. It's all fixed now but it took time away from the Mule.

I installed the 4WS kit I got from Charles Witt (muleman7). It was a very complete and nice kit. Anybody that's looking for a kit I'd recommend the one from Charles.

Image

Along the way I found this tag on the passenger side drop axle cover. I'm assuming it hadn't ever been apart? unless the person that took it apart put the tag back like I just did.

Image

The 4WS is a huge improvement from the 2WS. I couldn't make a U-turn in the street I live on before, now I think I could turn around twice.

Mule is looking good Lance, those newly painted wheels REALLY show how faded the paint is on your mule when you got it. I like the drilling block idea to make sure your holes are being drilled in the right place, (the first try). Having to use 'binocular bolts' makes them hard to thread when you goof and drill two holes side by side. Image :lol:

I started working on a passenger foot basket. So far I have the mounting block. Time to break out the tube bender and start making the actual basket.
The choke will get relocated over to the drivers side near the on-off-start switch. I have an electric start so there was no reason to have the pull start ferrule? on the passenger side any more.

Looking good Lance, you do nice work. Are you planning on putting a threaded screw through on that fitting, or will have a lock screw only on the bottom tube of the footbasket? How are you planning to bend the 1" tube in that tight turns used on the foot baskets? Looking forward to more photos of your progress.

Good question on how to secure it. The obvious choice would be to replicate something along the factory lines but then in my opinion that's way overbuilt.... I really haven't decided. It's the weekends project so we'll all know by the end of the weekend.

The bends are going to be 3" radius (I already have the dies). The factory bends were 2" radius. The 2" radius dies aren't even available for my bender http://shop.pro-tools.com/products/manu ... ty-package let alone paying for a set of dies to do 8 bends. So it'll have 3" bends. Guess we'll see how obvious it is that they're not the same.

I have found the same thing. Just about every tube bender I have found has only 3" radius for their smallest dies. I would not think that an additional 1" wider radius on 1" steel tubing would look really obvious, but you won't know for sure till you try it. Are you using steel or aluminum tube on your footbasket?

Well It's done or at least less the expanded metal which I'll do in the morning and paint everything of course. I also have to make the pockets in the deck for the seat back.

WOW Lance, looking 'great' (better than good). What gauge tubing are you using on the foot baskets. I assume the seat back was made with the same tubing. Do you have any detail images if how you connected the the steel tube to the screw clamp on the bottom tube?

I put the expanded metal on today and worked on the pockets for the seat back a bit.
Drilling holes in the deck. I think I measured about 10 times before drilling. :shock:
