Re: Engaging 6x6 under Braking

Interesting... There must be differences in the system between varoius markets then, because there is no clear explanation on how this works. In the parts manual there are 2 switches on the pedal - 20 and 23. 20 is the brake failure warning, turning on permanently if the pedal overtravels (manual re...

Engaging 6x6 under Braking

Hi All, I read regularly that the Volvo has a system where under heavy braking it engages drive to the front axle to avoid the rear wheels locking up. However, what does this? I have read through the maintainence manuals, owners manuals and looked at the brake system diagrams and there is nothing th...

Re: Volvo ratios

Perhaps to answer the first question:- Portal box reduction = 2.06:1 - all versions Diff ratios = 9x33 = 3.666666 (x 2.06 = 7.553333:1) - TGB20 6x6 9x31 = 3.444444 (x 2.06 = 7.095555:1) - TGB13 6x6 11x32 = 2.90909 (x 2.06 = 5.992727:1) - TGB11 4x4 Transfer Case ratio = all versions High 1:1 Low 2.39...

Re: Volvo leaf to coil Spring conversion

I knew I had seen one somewhere... and after much searching.. there is was in you blog...
I guess you already know that one.

Heaps of Land Rivers have been converted to Volvo axles, and many of them are running coils. That set up shouldn't be too hard.

Jez at HOFS may be able to help...

Re: Planetary gear leak?

Two places I know of are:- http://www.tatanka.nu/ - they have all the C303 parts available. and http://www.flyingspanners.net/ - who do a hub seal conversion. I need to resolve the same issue myself and will be visiting one of the local bearing suppliers to see if I can get matched seals. I imagine ...

Re: Planetary gear leak?

Hopefully this worked.

Hub section was extracted from one of the Volvo manuals (can't remember which one). The red circles show the three seals.

And a picture of my hub dismantled...

Re: Planetary gear leak?

Hi Marcus, The outer seal is the notorius "Stefa" seal. It is a dust/grease seal as the outer bearing is greased. The next seal is on the portal gear and prevents the oil getting from the gear side/inner bearing to the outer bearing. The nut on the shaft has an O-ring seal to prevent oil leaking thr...

Re: Full hydraulic steering

Isn't full hydraulic steering illegal for road use? I thought the regulations required a mechanical connection, which doesn't exist in the hydraulic systems.
It's fine for competition trucks which are not road registered.

Re: Started video documentation for the C303 restoration!

Why don't you build yourself a garage so you can work over winter? Then the trailer can go where your truck is. :idea:
You know it makes sense...

Re: Just in case...

I have 3 sets of the high ratio (read 4x4 ratio) for my TGB13 6x6 sitting on the floor in my lounge (where else would you store them). Whilst not fitted, the quality looks excellent and Jez is extremely helpful and regularly kept me up to date on progress of my order. Will happily deal with him agai...

Re: TGB 13 6x6 "grumble"

Cheers Uli.
I gather that this is not typical and therefore something I can fix.
I took the rear prop shaft off and ran it with only the front rear axle driven, and the noise goes away.
Guess the PTO should be the next investigation.

TGB 13 6x6 "grumble"

Trying to acertain if the noise from my 6x6 is typical or needs help. I find when accelerating "on throttle" the rear axles are quiet (it's relative!), and when decelerating "off throttle the rear axles are quiet, but when holding a neutral throttle there is a terrible growl from the rear axles whic...
