Thread: Maxidrive axle flange keeps on loosening

Thanks all, does anyone know the size and length of the 5 bolts used for the drive flange to hub?

Just happens I've been messing round with flanges/bolts in the last few days:

County (thick drive flanges) 50mm, M10x1.5 Grade 10.9
Tdi vintage Defender (thin flanges) 45mm, M10x1.5 Grade 10.9. Landrover P/N is BX110095M.

I haven't played with anything newer than a Tdi so can't confirm if the later defenders are the same.

Thx,

I measured the existing bolts and tehy are only 35mm so I woudl imagine with a Maxi-Drive flange being thicker there isn't that much left to grip.

I have decided to go with teh following:

Nordloc washers
A longer allen key bolt (45mm) but also bouth 50mm but need to check whether they will work.
Locktite

Question on the Locktite, I bought the 263 which is the high strength but I see most people refer to the 243 (which I presume is medium strength. Any views on whether I should use the 263 or will I have trouble later getting it undone?

When I was writing my earlier post, I was fairly certain the new bolts I was supplied with were 35mm long. IMHO too short with maxi-drive flanges.

I also believe I replaced them with 50mm long bolts, but had to counter drill the hub slightly as per my earlier post.

From memory, 45mm long would be about right and not need counter drilling, but I saw advantages in using the 50mm long bolts.

I checked last night and the maxi-drive flange is pretty much the same thickness as the standard defender one (ie thin flange). Within 0.5mm.

I personally wouldn't use allen head bolts as its just another "special" tool you have to have should you ever need to get the flange off trackside.
Your choice though.

50mm bolts on thin flanges became shank-bound when I checked. You might be OK if those Nordloc washers are pretty thick, but best to run a bolt in and measure before fitting the flanges.
If you've been running shorter bolts make sure you clean out any sealant inside the holes as it can be enough to hydraulic and stop the bolts going in to far enough (or rip the threads out if you force the issue).

Don't have any experience with the high-strength Loctites apart from bearing retainer so can't comment on that.
