Salisbury diff housing failures

**goingbush** · 21st September 2016, 09:54 AM

My lathe will do just 750mm with a tube mounted in the chuck if I put the tool post on backwards, I could do a run of the inserts but would need them pre cut to approx length about 755 mm / 405mm .

if you can't find anyone local I could have a crack but need to fix my motor first, its just started playing up, lathe wont start up in reverse .

want to sell it?

Nothy, You can have it if you want it, reason I changed it out was it leaks on the long side where the tube goes into the caste centre and I happened to have a spare lying around at the time. It has the brackets on it for a maxidrive actuator and stoneshield as well. Freight might be a killer - where do you live?

Damien, I measured it up today
long side is 715mm
short side 395mm
inside diameter (diff end) 68mm
outside diameter (flange end) 67mm
tube OD 80mm
The 1 mm difference seems to be from where the flanges are friction spun onto the tube and there are 2 ridges of about 5mm sticking up just inside each flange which would have to be machined or ground off with the extra 1 mm to allow the insert to be pushed into the tube.

Thanks Brian, so not as straight forward as just sliding a sleeve in then. Sounds like the 66.4mm hollow bore would do the trick as the tolerance isn't really going to matter.
But am commiting myself to using the 65Nb schedule160 pipe now as i think it will be better.
So if i was to get it machined down, would it be to 67mm or 66.8mm etc..?

No unfortunately, I would think that making the tube OD just a smidgeon under 68mm and take that extra mm out of the flange along with the friction weld ridges would be the best outcome. Thoughts?

Sounds good to me. So 67.8mm and bang it in the freezer if need be to fit it.

**Vern** · 21st September 2016, 04:07 PM

That will leave a sleeve with a wall thickness of 6.93mm, so total axle tube thickness of approx 12.73mm😎

Vern, if you like give us til tomorrow and I will get a price on supply and machining.

**Vern** · 21st September 2016, 05:30 PM

Ok then. Sounds easier😊

Keep in mind it an engineering shop giving me a price.....I put a few hundred dollars through them each year...will see what they can do
