Getting this 86' 6 cyl Trader work ready

In the 4 cyl Mazdas the thinwall liners were hand pull and install......quite amazing quality for a cheap truck .

Many years ago, way back in the 80's when I was a younger lad fixing lifts (elevators for Brocky)

Bare with me here

Occasionally we had to change a bearing on a gearless hoist motor
These are a really tight press fit the factory

We would cut the outer shell with a grinder and then split it
Then pry all the rollers out and pull the cage off

There is a point to the story

We then cut through the inner bearing case and would split that off

At a guess the bearings were over 12 inches OD, thinking closer to 14 inches
The ID was maybe 7 inches

We then would get a cheap foam esky (cooler for Brocky) and cut the end out to fit over the hoist motor shaft and silicon the esky on
We would prop the esky up on blocks of wood and fill with liquid nitrogen

It shrunk the shaft a huge amount

After maybe half a hour, we would just smash the esky off and quickly slip the big bearing

So now that waffle is done, not knowing exactly were you are, most vets or herd improvement companies have plenty of liquid nitrogen on hand

So maybe just get some from them and really shrink the liners and maybe just push them in by hand with a glove on

Yep, that's the best way.  The videos I saw more or less had them dropping in.

When I did mine,   I'm wasn't sure how easy it is to source/use  and then how quickly it boils off as you do the six liners.

Hence I tried dry ice first.  3kgs of dry ice (-76*C) is about $70 from memory. available at CIG and places.

I figure if I can do them in the Kenworth's VT903 I reckon this engine should be OK. I'll take everyone advice using the dry ice.
The 903 was like rebuilding a giant version of a 350 Chevy. Getting the heads on and off was the hardest bit due to the blocks surface angle but pistons and liners slipped in by hand.

The rear engine busses were the same ...the sloped block would dislodge the seal rings ..........one time I had a 6/92 head fall right out of the bus and onto the dirt .........I gave it a sweep with a straw broom ,and stuck it back on the engine ......... a guy was watching me ,he didnt say a word.

Looks like I have to wait now until I return to Victoria to grab the pistons and liners I need.

The place I was looking to buy a rebuild kit from, who advertise them is just a BS parts suppliers now and known for abusing everyone that makes simple enquiries with them. You should read the reviews on google. (wish I had done so first) Not naming them but they have a place in Craftsman Ave Berkeley Vale NSW. I wrote an honest review just to see what he would say and sure enough boom.

Nothing has changed here as years ago when I lived on the Central Coast and these guys were at North Gosford they were so hard to deal with.

SMS diesel, Lidcombe,  I used to deal with has given away stocking these earlier Trader parts now but still are great company to deal with for other Japanese truck parts.
ABC diesel (Asquith) were squeezed out of Sydney moved up to mid north coast to Coba country, Nabiac.

I use to use Brett's in that general area for all of the parts I needed for Lorry the Hino. 
Hopefully it's not them but I don't need to know as we no longer have Lorry.

Brakes / clutch are sorted need some pistons/rings, liners and gasket set which I'll sort out back in Victoria.
Just hate dealing with companies that tell you they have all the parts on their website but really don't have them at all.
 

or send you different branded oil filters to what you bought.  Or supply rocker cover gaskets that don't fit and leak.
