It’s A Roller!

Published by John under Tractor

Not under it’s own power, but at least its not on blocks anymore.

‘ still a long way from done, but will probably wire ‘er up first to be able to move it in-and-out of the shop at times.

Suspension & Wheels

Published by John under Tractor

Neither Front nor Rear mountings are done at this time:

When looking at the photos of the front, you’ll notice the piece of
2″ ID Mechanical Tubing welded to the center cross-member, under the
radiator. This is for the front oscillation pivot. The visible square
tube (2″x2″x1/4″) on top of the axle will bolt to the axle using the
original bolts for the leaf pack. I will weld a bracket from this
square tube to another piece to create the pivot.

The rear frame is cut-out (C’d) for the rear axle and will have 2
1/2″ x 1/4″ flat bent in the shape of the “C” and welded to the inside
of the frame. Additionally, I will take another piece of frame – from
the 7′+ section standing in the rear of the garage – and “C” out of top,

slip this piece in from the bottom and bolt to the outside of the frame
and lower edge of the frame… somewhat hard to explain without being
able to use my hands to talk. ;^)

The wheels were definitely a trick with a lack of machine tools at home. Low-buck, but here’s what I did:

  1. I took the Schrader valves out of the valve-stems to insure all air
    was out of each tire figuring the heat might make the air expand too
    much.
  2. I then took my dividers and slid one end around the 4 1/2″ hub hole
    with the other end set to create the necessary diameter center to go
    inside the 16″ wheel.
  3. I “rough cut” the center out of the wheel with the torch.
  4. I set the axle up on saw horses and bolted a jig-of-sorts made from
    angle to where the leaf springs mount on one side. My hand grinder was
    band-clamped to the jig so as to place the grinding wheel up against
    the edge of the rough-cut wheel

    center. A stop was used to prevent me from grinding away too much material.

  5. Bolt the wheel center to the axle hub and rotate by hand while running the grinder.

The 16″ Pickup Truck wheel are actually riveted together. The bolt
center is riveted to the “ring” (for lack of proper terminology) in 4
places with 3 rivets each. I left the rivets in, but cut the “bracket”
part free from the center. This allowed me to weld only to the riveted
bracket instead of the rim ring. My wheel is now assembled exactly as
the original except with a welded center instead of a one-piece stamped
center.

After doing the first, I tried cutting the center out of the
wheel with a jig-saw and metal blade… Slower going at first, but with
copious amounts of oil on the blade while cutting, it definitely made
short work of the finish grinding.

The dropped axle could create ground clearance issues on certain
terrain, but it’s what I have to work with at this time. Although our
yard is not flat by any means, there’s nowhere I can high-center so it
should work for me.

Tractor From a Ton-and-a-Half

Published by John under Tractor

I’ve been tinkering with this project in my spare time since April:

Tractor Project

It’s a conversion from a 1958 Chevrolet Series 40 ton-and-a-half. (I’ve got other
plans
for the truck body.)

Since our garden is already growing and we won’t be doing any major
exterior improvements this year, my hopes are to get the actual
foundation of the tractor up-and-running this Summer. Then install some
sheet-metal and possibly FEL during Autumn/Winter and come out strong
for ‘08.

The hydraulic pump that was previously driven from the transmission
PTO will be relocated and belt driven from the engine pulley. This will
allow use of live hydraulics and free the trans PTO to drive a
traditional rear spline.

Rear View

I had intentionally left the frame long, figuring that I could
always cut it to length after completion. My reasoning was that I’ve
read about many projects using 2 transmissions for gear reduction and
may want to do something similar in the future. This would require
setting the rear further back than it is now. The challenge is that the
truck pinion yoke is off-center a few inches and it may make more sense
to build a gear box.
