looking for LT230 reduction gears

[def-90]

ok not sure this is the right place for this but i'm chasing some LT230 reduction gears prefer 30% will probably take 50% gears though.

reason, goin V8/auto and would like some Xfer gears, and as maxi no longer is around i'm having trouble finding some.

cheers

Not any more. My understanding is that Dave only produced one run of the 80% reduction gear set (used a different method to Maxi-drive to get 80%).

They didn't sell as well as the underdrive (on pto) that offers a much greater reduction with low-low, low, low-high and high.

I heard that Dave's supplier used sub standard steel/methods, so there were a few premature failures...

Maybe it is time for Dave to have another go?

wasn't there talk on here that MR had bought the rights off Mal and was going to start producing gearsets ?

Hi Def-90;

Reduction gears for an LT230 TC are still kicking around from Maxi-Drive , spoke to Hi-tech Engineering last week which fitted a 30% reduction gearset ( I think ) to one of our Club members Discos

Call em 02-47217783

Has anyone looked into having their own low range gears made by a machine shop with gear cutting expertise? If not, am thinking of doing it myself later. Note you need to remove the low gear from the cluster on the intermediate shaft and securely fit a smaller one. Maybe making copies of Maxidrive gears would minimise design work as they seem proven good ones. They are straight cut gears, which are easier to make than helical.}. Extra noise from them should not be a significant problem. (Wouldn't want straight cut gears in high though!)
Indications of how the likely cost of having gears cut and heat treated etc should be interesting Wonder if decent ones could be made for less than around $1500, which I gather is about what Mal used to charge.

FWIW, there are some excellent race car gear manufacturers in Australia including Holinger Holinger Engineering (http://www.holinger.com.au/) (although I doubt he'd be interested as he used to have miles too much work with the V8's and BMW Motorsport) Pfitzner, http://www.ppgearbox.com.au/index-html.htm Albins gear, Albins off-road gear : Front page (http://www.albinsgear.com.au/) etc.

Maybe one of these speciality shops could generate sets ?

Mal (Ex maxidrive) still has a few bull gears left. Mal said he may make them in his spare time till used up. Now will be an exchange setup so you need to know what gear suits your box 1st or it will be out of action for a wile.

cheers fellas,

spoke to barry at hi-tough today and he's having a chat to mal t'row for me. yeah he still has orders for O.S he is completing and turn a few more out until he's outta gear.

MR automotive are still in chats with mal re. making the gears, they're having another next week and by then they should have a fairly good idea if they will take them on or not.

cheers

Sorry Baz - that is a high range kit. These guys are talking about low range.

[def-90]

dammit baz you got me all excited there for a second!

well as it turns out mal has none left and will not likely have any, but i have sourced some second hand, yet to clinch the deal, sclarke you dont really want your set i don't think....ummm...they don't match the colour of your county!!:p

Ok well it look s like mr automotive (32846688) 99.999% will be taking on the maxi Xfer gears, at this stage same price $1650ish. so all looking for some can give warren a call.

so i just got to work out if i want the 30% for that price or 50% for a cheaper?.........

thinking the 50% may be too low (4.4, Zf auto, 3.54's and 35's)

any thoughts?

Does this help?
ZF Ratio (1st at top, 4th at bottom) High range (1.003) High range (1.22) low(stock) Low(30%) Low(50%)
2.48 8.81 10.71 29.16 37.90 43.73
1.48 5.25 6.39 17.40 22.62 26.10
1.00 3.55 4.32 11.76 15.28 17.63
0.73 2.59 3.15 8.58 11.16 12.87
All with 3.54 diffs

With a manual, the best solution would be to have no ratios which cross over (i.e. 5th low is slightly lower than 1st high), but I am not sure what is best with an auto. 50% would give you a bit of a gap between 4th low and 1st high - but that may be OK - torque converter and powerful engine should compensate.

You will be spending a lot of time in 3rd-4th low offroad - how strong are they?
