Thread: County rear disk brake conversion, pics & p/n's

Just out of interest, has anyone done the measurements using old two door Rangie hubs? (I am assuming they will have the same bearing spacings as 110 County hubs.)

dont assume, apparently there are 2 versions of the 110 hub, BEFORE the Tdi narrow bearing hub....

I think all the 110 front hubs are the wider spacing, but there are two different rear (drum) hubs, wide spacing on earlier 110's with slotted keyway in the stub, and narrower spacing on late 110's/early Defenders with the flat machined on the stub, this spacing is narrower than the earlier hubs, but wider than later Defenders which have the very narrow spacing.

I know that the very early 2 door rangie hubs don't take the LR alloy rims, but I have access to a pair of rangie assemblies and am wondering about using their hubs to get the '91 Defender track correct. Just thought someone may know.

If I'm correct the '91 Defer has the same CV's as the 110 models, so likely the same front hubs.

not really sure what alloys fitting has to do with the rear disc conversion?? If your 91 Defender has a track width of 1551 wms-wms, then I think you will find that the early RR hubs will not make your rear drum Sals be the same, but 16-20mm short over all as the 110 front hubs are....

Early rangie hubs can have problems fitting alloys due to the larger outside diameter of the hub, only a by a small amount which can be machined down relatively easy.

86 vogue alloy wheels wouldn't fit a 81 hub until it was machined.

When I first bought my 120 (MY 87), I swapped the front hubs to the rear, and fitted a pair of early rangie front hubs in their place on the front. I did this, not only to convert the rear from drum to disc, but the rangie hubs had been converted to vented discs.

The moral is that those early rangie hubs had the same bearing spacing as the 110/120.

However the rangie hubs I used were the early ones that have imperial bolts and a slightly different pitch circle for the drive flange, and the drive flange from the 110/120 wouldn't fit. Ashcroft, etal make suitable flanges for these early hubs to be used with 110 half shafts or cv's.

It still remains to be confirmed if early rangie rear hubs will give the correct wheel track.

I have to say that I have read many threads about converting drum rears to disc, using either early front hubs or later hubs and stubs, but my memory is that this is the only one that revealed the issue of the narrowing of the track if using early front hubs. I'm guessing that most of those other threads (non Aus) were for peeps with 90's, and they don't notice a problem with clearance between the tyre and rear spring perch.

John, Eric confirmed that the early RRC hubs do not give the correct wheel track when fitted to a pre 87 stub axle. They appear to give the same result as the county front hub.
