Guy goes into a garage to grease bearings.....

[mfenmor]

Way to cold today. I didn't even want to go out and start the fire.
No work today.
Tomorrows another day.

[mfenmor]

Another cold day, but managed to get my butt in gear and go start the fire in the garage.
Outside thermometer said 15.
in the garage....

Got all the engine and trans mocked up.
tomorrow I'll paint and drop it into the tub.

slots to adjust the belt length.
I'll add jack screws to adjust the position.

amazing fabricating mike ...hope you don't mind me being totally engaged in your project . after designing and building kiddie rides for 15 years , i love the creativity of a build like your doing . my mind starts visualizing whats next and how will it be tackled. latest thing is thinking about your portal boxes and the sprockets and chains in them wondering what size chain , and how will they be able to be tightened if needed. i,m thinking of some kind of the hard plastic chain tensioner material inside the portal half way between the sprockets on one side of the chain that could be adjusted from the outside of the portal by a watertight bolt ... ? or something . maybe you have it figured out already .. and i'll go wow ! what a great idea . j.b.

Thanks JB.
I build kiddie rides too, just for bigger kids.

I got a little more room in the garage today...
Because frame is in the tub! WHOOHOO!

Let the assembly begin.
Had to trim the skid plates a bit. I only want one layer between box and frame.

But not for a few days. Gonna be busy plowing 2 feet of snow which has already started early.
Glad I got a Max Kubota WG750 with a snow plow ready to go.

I got another idea.

So I warmed up the garage today in anticipation of getting the drive train installed, However...in my excitement of getting my new portal boxes done, I forgot to order new inner bearings! The original start of this thread. DOH!

Ordered new bearings FIRST!

So I just attached the boxes to the frame in tub.
This took 4 hours today. Fun fun fun.

A little silicone, no water in please, no oil out.

1/2"-20 grade 8 bolts fit in VERY tightly. Bolts mic'd at .496 so drilled and reamed holes to .496
No threads in the holes, all shoulder.

IMG_0562.jpg

Torqued to 90 Ft. Lbs.

I feel VERY confidant no further support will be needed for these.

Gotta wait for inner bearings to go any further.

Had to trim the skid plates so only one layer of material between frame and boxes.

I'll start installing T-20 and laterals.

looking awesome mike ...excellent job. i'm really looking forward to the portal box chains installing , etc. the portals do look very stout . j.b.

[john swenson]

i just went back and looked closer at the picture looking down in the portal box. are the 2 bolt holes facing toward the center slotted ? chain tensioning system ? j.b.

Sorry JB, no slotted holes.

Another five hours in the garage today,
Got the T-20 and engine mount installed.

It's amazing how some of the small stuff can take up so much time. I spend 6 hours today on the shift linkage, though I did make new couplers for the diamond shifters.

Got the inner bearings installed.
I made this centering shaft so i can tighten flanges without axles installed.
If you try to tighten the flanges without an axle installed, it may not be (and probably won't) be aligned with the outer bearing.
Smack the shaft while bolts are semi tight to settle bearings straight.

I marked my bearings so I know where the grease holes are in them, then I line them up with the grease zerk. Just my OCD.

Had to pull the boxes back off.
The bearing retaining bolts interfered with the bottom of the tub.
Got the heat gun out and will make a few more mods just under the frame.

You can see where it was bolted to the frame, and the tub just starts curving under where the bearing flange starts. Not much to move, but just enough to make you go "GRRR"
