Salisbury Rear Pinion Replace or Adjust?

Hello All,

G'day Tins, I am not sure whether the link for Mike from Britannia Restorations that you sent me is the same one I found last night when I was digging around ... before the electricity went off ... however, there is a lot of air time that shows the differential casing spreader that Mike uses. It looks far less complicated and less expensive than the ARB spreader. Accessed 22 June 2024 from,

It looks worthwhile looking a the third alternative and seeing if it fits the Dana's as well? Fingers crossed!

Kind regards
Lionel

To check directly whether the issue is the pinion, it is quite easy to remove the rear cover on a salisbury (less messy if you drain the oil first), and you can see exactly what is happening.

Note, my 110 is now well over 700,000km, and I have had to replace one (RH) drive flange, and I have got the replacement half axle, but have not yet installed it, as the splines on the axle are well worn, but no issues with the diff. But while it has done a lot of off road, and a lot of towing, and has the rather rough Isuzu engine, there has been little towing heavy loads, and rarely operated close to maximum load.

Apart from the worn splines, and two sets of brake shoes and one pair of drums, the only rear axle issue has been a failed RH wheel bearing.

The ARB one locates in the housing and spreads it apart, the one used in the video compresses the housing to spread it apart.

I haven't had to overhaul a Salisbury but recently 'found' a spreader (pic attached).
I did buy a Series IIa GS some years ago that had a Salisbury rear axle installed, the half shafts were welded to the drive members to overcome backlash or loss of drive !!!

Yep. Same as the Datsun workshop tool we used on the BW diffs in locally assembled 200B and Stanza cars. They certainly didn't have the longevity JDNSW describes from his Salisbury. Some howled from the factory.... All the imports had IRS. Never needed to touch them.

Wish you hadn't mentioned Danas... OKA has two of them. I have a noisy front wheel bearing... What next?

Have you ever hit a rock with the front one?
I have on mine and thats why I am making that guard.
One river crossing a rock made a hole in it, saw the oil in the water. When I got out I had to drain the oil, bash out the dent and filled the hole with Sikaflex.
I carry 2 litres of diff oil so I was OK. The engine and gearbox use the same oil and I carry 10 litres of that. could have used that in a pinch.
Just wondering as Okas have one in the front from factory, do they give it any protection?

Hello All,

I contacted Mike about the differential case spreader that appeared in one of his earlier YouTube clips. Mike sent me the following link that features a YouTube clip all about how to make and use the spreader. Thank you very much Mike - it is greatly appreciated!

Just got to do some conversions to Metric so I can understand the sizes required.

Kind regards
