Like the range of gear ratio's? I also wonder if the bogie-drive on the 6x6 was uniquely designed for Volvo, or whether it had other applications as well, before or after. http://disc.server.com/discussion.cgi?id=54728;article=2296 xxxxxxxxxxxxx Anders Rydén Portals Fri Jan 27, 2006 22:08 81.225.53.97 Portal axels have driveshafts that are not concentric with the hubs. Somewhat like this (extremely crude) scetch _ _ |/|I=======(O)====I|/|<- here are the drive shafts |\|I /\ I|\|<- here are the hubs |/| /XZ\<- rock |/| ============================= Compare this with the ordinary axle below _ _ |/| |/| |\|I====/\=(O)====I|\|<- hubs and drive shafts in line |/| /XZ\<- rock |/| ============================= As you can clearly see in my (excellent) illustration, the portal will clear the rock where the ordinary axle will get stuck given the same size wheels. And if your axles are the original axles, they are _not_ Dana 44's. That is a common mistake. They are Salisbury model 4HS-001-85 front and model 4HA-00-92 rear. However Salisbury was bought by Spicer, which changed it's name to Dana Corporation in -46 and Salisbury is now called Spicer Axle Division. I found some info on Rzeppa joints on RZEPPA JOINTS The most common type of outboard joint is the "Rzeppa" style. This type of joint was invented way back in 1920 by a Dana engineer named Alfred H. Rzeppa. His design allowed power to be transmitted through six spherical balls located between an inner and outer race. In this design, the balls are held in position by small windows in a cage assembly that fits between the inner and outer races. The design of the joint is such that the position of the balls always bisects (cuts in half) the operating angle of the joint. It’s a slick design that works something like a bevel gear. But instead of gear teeth transmitting the torque across the joint, the balls push against their respective tracks in the inner and outer housings.

I was surprised to hear about the original axles NOT being dana 44's though! They seem so close - And (it's been a while) but I'm pretty sure the ring/pinions and seals from a 44 all work on this axle. The portal axle explanation was clear - I first saw this type on a picture of a pinzgauer (sp?) and the moderna day Hummer H1 also seems to have this type of "offset" axle. I just never knew it was referred to as a portal. (I was imagining you were all referring to a european word for "half-shaft" or something.) Thanks to those that contributed to wikipedia. xxxxxxxxxxxxxxxxxx -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] To: Volvo303@yahoogroups.com From: jb Date: Thu, 2 Feb 2006 10:18:58 -0800 Subject: Re: [Volvo303] Interesting axle details Reply-To: Volvo303@yahoogroups.com On 2/1/06, Willem-Jan Markerink wrote: > > On 28 Jan 2006 at 21:55, Willem-Jan Markerink wrote: > > > Does anyone on the list have knowledge of this particular > > model/series of Salisbury? > > Like the range of gear ratio's? > > I also wonder if the bogie-drive on the 6x6 was uniquely designed for > > Volvo, or whether it had other applications as well, before or after. > > > > http://disc.server.com/discussion.cgi?id=3D54728;article=3D2296 > > xxxxxxxxxxxxx > > Anders Ryd=E9n > > Portals > > Fri Jan 27, 2006 22:08 > > 81.225.53.97 > > > > > > And if your axles are the original axles, they are _not_ Dana 44's. > > That is a common mistake.

I've also been told that the Volvo portal axles were built right along side the Salisbury axles. -jb
