Thread: My saggy old lady

You can get 9.00x16 MRF Bar Treads from Ag Tyre Service in Moree. Not sure they will fit under your standard setup - though they are standard on the 1 tonne version of series landies.

Ask Banjo about the suspension, he's just done his.

From what I understand, the 9.00x16 tyres will give a stock motor a hard time, and your diffs/axles an even harder time. A good method of getting the old girl beter off road is softening the springs.. there are some who have perfected this idea on the site.

9.00x16's will also throw out your ratios a bit I imagine..

9.00x16 were optional on 2a at least, and standard on the One Ton. But the One Ton was lower geared and had the six cylinder engine. With standard gearing and either of the four cylinder engines you will spend a lot of time in third gear and low range.

The One Ton also had lower geared steering, and 9.00x16 tyres won't improve the steering effort.

Spring over axle has been done on Series Landrovers, but I have yet to hear of an example that was considered a success. Engineering approval, if you need it, is unlikely.

As mentioned, 9.00x16 tyres can be found but tend to be expensive.

Was the one tonne the swb with cutaway guards? cause mine is a lwb soft top which was a 6cyl 2.6 Landy engine but I had an incident where those pistons were destroyed. I've swapped to a 202 with 186 head. So the 202 should handle the extra strain but I'm not sure wether it has lower gearing in it (i do start in 2nd though).

Thanks,

The One Ton was a 109" model that was not generally sold in Aust. As the name says it had a 1 ton load carrying capacity. It did not have cutaway guards.

"The 1 Ton 109" - produced from 1968 to approx 1977, covering late IIA and early series III Models. It was basically a Series IIB Forward Control built with a standard 109" body, featuring 2.6 litre petrol engine, lower ratio gearbox, ENV front and rear axles, (Salisbury front and rear on later Series IIIs) though some late IIAs were fitted with ENV axles in front and Salisbury on the rear. The chassis frame was unique to the model and featured drop-shackle suspension similar to the military series Land Rovers. 900x16 tyres were a standard feature and these machines were commonly used by utility companies and breakdown/recovery firms. Only 170 IIa and 275 (approx) Series IIIs (1 Ton) were built for the home market.

So your vehicle is not a 1 tonne and your standard axles/front rover diff will not survive trying to turn 9.00x16s. Also the holden motor does not rev as well as the rover motor so also may have issues (but the the tyres will act like an overdrive so it might go OK). If you do go to 9.00x16 you will need 4.7 diff ratios, stronger axles in the rear and major diff/axle/UJ work at the front (Rover Diff) - the rear Salisbury should be OK.

If you vehicle is a standard civilian series 3 with out the raised military spring mountings,(not long shackles) then I would suggest that to get better spring articulation you fit Parabolic springs and matching shockers,this will give you about a 1+inch lift,without having to modify either UJ's or chassis X members (driveshafts rub on full deflection) if you wish for more clearance then fit 8.25 x 16 tyres a local bloke has them on a Toyo-four runner, quite sucessfully on beach work they are standard A/T pattern


cheers

UncleHo: this is exactly what i am now thinking..

Garry: thank you for your info

Anyone: what height is the 8.25x16 and where can i get them? and are the parabolic springs something i could find at my local 4wd shop or would landy ones be a hard find?

Thanks all,
