[AT] OT: wheel packer question

[CRAWLER HEAVEN]

Stuart, Instead of gear oil you might try Corn Head Grease It turns to
liquid with heat but turns back to a jelly when cooled,it would so down the
leaking and it sticks and lubes well in a cavaity not like regular grease. I
use it in all my bottom rollers and front idlers i get mine from John Deere

Subject: [AT] OT: wheel packer question


Since things seem a little slow for tractor discussion, I will ask for some
help that is sort of tractor related.

I work for the County road dept. in the summer and we have an old wheel
packer that needs some repairs.

This unit has four tires on the front axle and six in the back.  There is a
large "tub" that is filled with gravel for weight.  On the sides are
placards saying "Ferguson".  The data plate on the front says made by Shovel
Supply, Dallas TX.  Unfortunately, someone pushed this packer from the front
and wiped the model and serial numbers from the plate.  We even removed it
to see if we could read the stampings from the back, but there were rocks
between the plate and the frame so the back was damaged too.

The engine and drive train is an Oliver tractor, probably a 770 or 880.
There is an Oliver data plate on it.

The rear drive wheels are run by large roller chains that come down from the
axles of the Oliver.  Of the 6 wheels on the back, the two outer ones on
each side are actually drive wheels that are connected to the chain case.
The center two wheels are just "tag" axles.

The lower unit of the drive wheel holds the axle, bearings and chain
sprocket.  They are attached to the chain case with bronze bushings that
allow the lower unit to pivot slightly from side to side.  I suspect that
this is to let one tire ride up over a bump without putting all the weight
on that tire.

The lower unit is filled to the axle level with 80/90 grease that also lubes
the chain and sprockets.  There is a seal between the lower unit and the
upper chain case.  This seal has to compress and expand to accommodate the
rocking from side to side that the lower unit does.  On our machine, the
seals are shot and all the grease runs out if you are on any kind of a side
slope.  We don't know if the seals are original or if someone has improvised
in the past.  In any case, the current seals look like they were poured in
place.  It is a rubbery compound (not RTV) but you can definitely see the
beads that were laid out.

>From the research I was able to do on the web, it looks like this was a
10-12 ton packer probably built in the mid to late '60's.  I have not been
able to find any source for parts or manuals.  If anyone has any information
that they can provide I would appreciate it.  Even ideas on how to make a
new seal for the lower unit.

Thanks,

Stuart
