Alternative rear axles

Postby Andy W » Wed Apr 19, 2017 6:35 pm

Hi,
Humour my appalling lack on knowledge once more please folks.....I am pondering whether or not I should change rear axle...

I have a 1275cc Marina engine with Metro carb, Mini Spares inlet manifold & DMG tubular exhaust manifold & complete exhaust system (thanks to Panky & others for helping me with that set up).

I have a standard 1098 gearbox & axle.
I will be fitting slightly wider wheels in the near future.

Would a Marina axle be better & do they need any modifications or are they a straight swap?

Thanks,
Andy.

Marina axle is diffrent pcd, 95.5, also you would need to relocate the perches and I think?? change the yolk on the axle end of propshaft for the marina one,

and rework handbrake cables,

easier option, 3.9 diff and hardened halfshafts, only trouble is good 3.9 diff are difficult to find, david manners group(birmingham morris minor centre) for harder shafts

Just for your info, I've got a Marina 1275 feeding a standard real axle, but with hardened half-shafts.

Have not managed to twist the shafts off yet.

Yet. :)

I have just fitted a ford escort rear axle to my van with 9 inch drums limited slip diff anti tramp bars. With the ford pcd gives a greater choice of wheels and tyres, this has all been done for a power upgrade this coming winter.

Ok, so I have got hold of a Marina rear axle, with Minor fit hanger brackets welded on, BUT, it has the Marina hubs still fitted...how do I go about changing over to
Minor hubs so I can use Minor wheels? Can I swap my existing axle's stubs onto the Marina axle?
Thanks,
Andy.

I thought one of the plus points of this conversion was that you could then use a marina based front disc conversion and then have the same wheels all round, just not Minor ones.

I thought the Marina axle also took Triumph Dolomite wheels, which possibly means Spitfire too, though that was a different rear end set up, but could be worth checking as the more cars that had the same wheels the greater your chance of getting after market or second hand ones.

What you say is true Sean, but my intention is to fit wider standard wheels to keep the car looking fairly standard.
I want to fit either 4.5" or 5.5" rims & keep the 14" diameter.

you can remove the drive hubs and have them redrilled to minor pcd, you may need a Churchill puller to get the hubs off though as they usually become very tight, while in there I would change bearings and seals,, oh and you will probably have to have the brake drums redrilled,

if you are going to this much trouble why not do as Custard says and us marina front end so all pcd is marina and put dolomite wheels on with hubcaps, a 165/13 tyre gives the same rolling radius as the 14'' wheel you can even go to 175/13 if using spitfire wheels

if you can find any how about 15'' with 185 tyres,

Very, very nice wheels Woody! :D

I'm going to go a different route so if anyone wants this Marina axle, they can collect from S.Devon & have it for £75.00.
It has hanger mounts placed for Minor, & has new cylinders.

Hi,just to add to this,although I realise that you already have your rear axle,I believe that the rear axle from a toyota RT104 has the same spring pad spacings as the minor axle so can almost be a bolt up fit with a bit of fiddling.
Have not tried to fit one but have run a tape over one and it appears to be correct.
how can you work to a budget when you own a morris minor?
