Angle gear.

Does anyone know if the angle gear is the same in a S60R, and a XC90 2.5T, both manual? My thinking is, if they're the same, I might buy a spare, and recondition it, just in case.

Post 790190 by Santa on 2015-11-07 07:57:10

I believe it is the same as the XC90 (collar gears are the same so cant image the angle gear being different).

Post 790197 by Dangerous Dave on 2015-11-07 09:59:46

Best thing to do is get underneath and have a look. Some angle gears had a chain drive unit attached, there are that many different versions. They did a strengthened version too.

Post 790201 by MoleT-5R on 2015-11-07 12:07:57

also it will require the same drive ratio as the rear axle, if you are building it as a swap in unit should anything go wrong with the existing unit iirc

Post 790203 by stribo on 2015-11-07 12:44:11

Are they not all 1:1 ratio?

I've got a spare one in the workshop I'll check later if your wanting to know

[QUOTE=stribo;790203]Are they not all 1:1 ratio?[/QUOTE] yes in theory when with the matching rear axle. so if for example the rear axle is 3.31:1 then the angle gear needs to match it but in reverse so 1 input turn gives 3.31 output to rear diff, thus in reality at the angle gear input 1 turn will give turn a the rear axle so a theoretical 1:1 overall. If I'm wrong in this thinking please shoot me now, but that is how I understand it, Dangerous Dave will be along in a minute if I'm wrong with a proper explaination

[QUOTE=stribo;790208]Yes please mate.[/QUOTE] I forgot and it's a bit dark now lol. I thought they were 1:1 and box matched the rear diff. Can check in the morning now.

Post 790267 by stribo on 2015-11-07 22:29:25

My understanding is, the front and rear diff are matched, and the angle gear is 1:1, just to turn the transverse output from the gearbox, to the longitudinal drive to the propshaft.

Early ones were 3.31:1 to match the final drive ratio of the diff (which was inherited/modded from the 900 series). If you check my build thread (in my sig) I've got my angle gear dismantled and you can see the difference in the gears. Think the later ones were changed to 2.78:1 (I'll have to dig out the data to check that and what year they changed) The front diff works seperately to the rear diff, think of it as the angle gear is added (bodged on LOL) to the drivetrain after the front diff, so you need an overall 1:1 ratio through the angle gear and rear diff. Bloody mind flock :)

If your having a spare, just buy a good one and weld the sleeve. Mines very low miles 38k from a p2 2003 but shaft is worn even at low miles, but otherwise perfect, I'll weld a new sleeve on and keep it as a spare, not that it fits my v70r

Not surprised it did go, I know they break if launched lots but I'm guessing his power upgrades didn't help.

It was launched hard by the looks of it :D It's completely different now, he's modded it loads

Post 790291 by stribo on 2015-11-08 00:06:45

Our S60R has been launched hard many times, I think the failures people have suffered are because, they don't realise they weep oil, and they run them dry, as they don't keep them topped up.

[QUOTE=stribo;790267]My understanding is, the front and rear diff are matched, and the angle gear is 1:1, just to turn the transverse output from the gearbox, to the longitudinal drive to the propshaft.[/QUOTE] nope the front diff makes no real difference to what happens at the rear (they still work in sync with each other), this thinking is what has kept my v70r awd off the road for so long as I got it into my head that the box I bought didn't match the rear diff, but in the end that makes no difference as long as the angle gear and rear diff are matched......kicking myself as she could have been back on the road ages ago.......:buttkick:

Post 790352 by Ettienne on 2015-11-08 19:58:12

How do the ratios compare on the xc90 to s60, should give you a rough idea. However won't the xc90 have a larger rolling tyre radius, so if they're geared similar on the tacho, there probably different lol

Had a look through some volvo tech stuff but can't find the ratios, they hide it really well :( Will keep digging...

(If that makes sense) I remember looking at axles etc when I was going to manual convert the laser I seem to remember the xc90 was different and ratio of 3.31, 3.66 and 4.3 stick in my mind.

Lol[/QUOTE] do you understand how it works now, took me a while to get my head around what is relatively simple really was just muddled by final drive ratio's of the rear diff and gearbox which really have no influence on each other as the cars FD is gearbox governed. Might be worth noting what rear diff ratio's / angle gear unit part no's and just watch for when they come up.
