2014 RTV 1140CPX New Project for Restoration - PART 2

This is a continuation of this thread: https://www.orangetractortalks.com/forums/threads/2014-rtv-1140cpx-new-project-for-restoration-part-1.70102/ I knew this thread would get long, so here is more work done on the RTV now in Part 2. The work has been coming along and I've gotten the...

CONTINUATION - Front and Rear Suspension and Hydraulics

Here are some photos of the project as of today along with some narration.

Rear Axle Completion:

Banding of the rear bellow that covers the Transmission drive shaft to the axle drive shaft (allows for spines to move as suspension moves)

Insert the inner bearing seal first - then insert the axle.

Then, draw the shaft into the axle

Here's the axle installed.
This is tricky and heavy.
The axle has to be lifted into place on the spring and the 2 shafts (transmission and axle) meet with splines lined up. Then the clamps are secured which locks the axle, and leaf spring shock support together.

And that bellows that you secured onto the axle shaft? Yes, that also gets a band where it meets the transmission shaft.
Be sure and grease those splines before assembling.

FRONT HUBS and BRAKES:

I think Kubota designed this very complicated system well.
The hubs are very precisely machined to small tolerances.
The parts fit perfectly and there are MANY.

Make SURE that the two halves of the case go together easily.
Ensure the alignment pins are unobstructed.

I used Red Rubber Grease on the seals and surfaces.

Ensure that the piston is aligned with the case when installing. I used my press to do the work.
The grease makes things slide easily.

Note that there are outer alignment marks as well.

That completes the brake piston portion of the hub.

Now on to brakes themselves...

 

[Nicksacco]

The brakes are composed of 3 friction pads and 4 steel discs. The friction discs rotate with the axle shaft via serrated teeth that match the splines on the shaft.

The steel discs are stationary. The have "teeth" around the perimeter that match with the inner case.


Install the shaft seal AFTER the bearing.

Now insert the Axle shaft and begin stacking the brake discs starting with a metal disc.

Watch out for Oring not remaining in the channel.

I use a contact glue for this kind of thing. Works great.

Bring the halves together carefully and ensure the Oring stays in place.
Bolt the cases back together and replace the bearing, retaining clip on the axle shaft, and the cover for the retaining ring.
Then insert the seal in that case half.

Now you're ready for 5 oz of UDT.

Whew! Lots of parts - and these guys are heavy too.

Next I bled the front brakes.

Then I attached the dump valve and filter housing/filter.

Once done, I changed all 3 Hydraulic filters and replaced the UDT in the tank, and transmission.
It takes 7 gallons to fill everything.

Remaining items include:

Painting
Front Wheel Alignment
Replacing all plastics
Electrical Wiring (going to add flashers and turn signals)

I hope this aids folks thinking about this kind of repair.

This machine is going to be so perfect that once it is done, you are not going to ever use it for fear of it getting dirty. Your work is better than the day it left the factory. I'd like to send you my 1979 Ford truck for a rebuild like you are doing. LOL.

Ha!
Thanks Dusty. I think it's gonna go in the Living Room as a centerpiece

 

[DustyRusty]

I like your way of thinking. I had a friend who didn't have a garage, but he did have a room with a glass sliding door. He removed the glass door and panel, drove the car into the room, put the glass back in, and worked on the car all winter. His wife wasn't happy about this sudden takeover of the room but eventually started to help him with the restoration work.

Perhaps I missed it in the earlier thread, but what are you using for ‘paint’? Specifically those gray parts.

 

[Nicksacco]

HI @chris_the_wrench

Grey on the axle cases and hubs is charcoal grey powder. I powdercoated these. It's not a perfect match but good enough actually.

Grey on frame and other frame related parts where I sprayed is Kubota Dark Grey Enamel. Quart is part number below. I have used Kubota spray paint and it's good, but I like mixing and spraying myself because I can control the curing.

I thinned with Xylene and added Majik catalyst hardner.
