Not gone to Biling.

Well the theory seems to be working on Percy.. but I did bung a sailsubry axle under as well for good measure. Hardly notice gear changes at all.

No, give it to me and I'll put it into a SIIA SWB

I saw you had posted these thoughts as mine went on it's way. I had actually been considering this when you posted your problem on the way to Billing.

Oi. me dad worked on the design team of that one. One thing you can say is that they were ahead of the times in putting 4 gears in it.

mind, I'd recommend the ZF 4-speeder, as fitted to RRs etc., nice box.

the ZF 4HP22 as fitted to Rangies etc. (or maybe an HP24, if you has a 4.6, IIRC) is a nice box and reputed to be stronger than the 5-speed manuals.

from what I hear, the 4-speed LT95 (early RR) is supposed to be the strongest of the LR manual boxes.

if you put a later RR one in, you can have the BW transfer box with the viscous coupling as well...

That has to be the right way to go. It's one less cable to piss about with for one thing!

This is exactly the combination Warren and I were looking at earlier.

The only drawback is you're (we're) then stuck with the ratios, whereas we'd have more choice with a geared transfer system. I'm not overly bothered though as Grumble has the original low ratio (by comparison) front and rear diffs. Dave White mentioned this issue at Billing and i've been thinking about whether it would affect Grumble. I suspect not, unless anyone can offer further insught :-)

Ok, I'll grant you that one. Problem was 2 of them had a tendancy to fall out of it......

Alex

How seriously are you going to off-road in Grumble? For my needs (mostly on-road with a few forays onto gentle ground) the low ratios are not that important. So it's OK to chuck the box in and then tune the ratios with the diffs. If you want the ultimate low ratio then this may not work out.

Even with just the standard 3.5 (albeit in very good tune) I'd reckon that a 70mph cruise would be achievable if the standard overall ratios were upped a bit and the props quietened slightly. With a 4.6 in harness I'm sure that you have more than enough to pull whatever ratio happens to be there.

I think it's the logical way to go and it does fit in with my other plans for rebuilding the front of Grumble - 't will free some space (especially on the engine cover and hi-lo lever area - so an aircon kit can go in with the digital dash) together with the benefits of the overall drive train protection.

Sod really, going as it did - especially as we've sorted the overheating problem. Cruising down the M1 at 75 without the heater on full blast was an absolute joy - till the transfer box went!

Grumble can, but doesn't 'seriously' off road these days - although 'very rugged terrain' is planned. The 'low' in a 101, as you know, is about 'gentle walking pace'. This is well handy at times and I'd like to keep close to it - although not for mud-plugging.

I think the issue is with the high ratio. With low revs the engine is not as efficient - so cruising at 60-70 only doing 1800rpm is not necessarily a good idea. 'pends on the box, but with a viscous Borg Warner, there are no options - as with a geared transfer, for adjustment of ratio.

Erm, if that makes sense... :-)

Yes, BUT they are supposed to stay IN the box. Not automatically deposit them on the road.....

Two words.

Hillman Electromatic.

The damn thing used iron filings and an electromagnet instead of a viscous torque convertor.

Now imagine *any* moisture getting in there.

P.

This is the new bleeding edge of clutch technology - magneto-rheological clutches and electro-rheological clutches - and the Hillman was made when ?

An idea long before its time. What a shame.

The reference I saw for it was a 1956 car. My father who started his apprenticeship in 1962 tells me that they would basically tell any insurer who came looking for a quote to write the car off. The garages hated working on them.

As for the 1100 automatic box, there is a story told of a mechanic at Macrae and Dick in Fort William in the late 1960s who had one brought to him with a noisy gear box.

A standard trick to quieten a noisy gearbox at the time was to pour a handful of sawdust into it to thicken the oil a bit. Worked a treat on the manual boxes of the day.

The result with the 1100s autobox was that the microbore galleries clogged and it tried to select all four forward gears and reverse at once.

The leccie fan I reckon.

The switch packed up so I though enough was enough and put a Rangie viscous fan back on. Also put the old rad cowl on and changed the water pump (although there didn't appear to be anything wrong with the old one - just a few less blades). The collective result is that cruising at 70mph (did I say 75 before? - silly me!) is an absolute joy ;-)

I did a test run after the MOT and was happily (accidentally) doing 85 with the temp at a steady 65-70^ - Only trouble being the noise - but the lead sticky stuff from Billing may cure that a tad.

Interesting. As posted earlier (topic Hot Rangerover), I'm sure mine RR runs hotter with the new water pump I recently fitted. The pumps are not all the same then?
