KevinNY Posted July 24, 2007 Share Posted July 24, 2007 Does anyone know the differences in the Santana Series III gearbox/Tcase that supposedly make it stronger than the LR Suffix C boxes and Tcases. I know the ratios are the same and the Santana has the beefier "Honeycombed" case, but are their significant internal differences in strength?

FridgeFreezer Posted July 24, 2007 Share Posted July 24, 2007 Are you meaning the Santana box (LT85) that was fitted to early defenders? Quote Link to comment Share on other sites More sharing options...

Phil Hancock Posted July 24, 2007 Share Posted July 24, 2007 It has normal suffix D innards in it. The difference is basically a mod in the production of the gears to reduce the tendancy to jump out of gear. Quote Link to comment Share on other sites More sharing options...

EDIT: Nevermind, I found that information. Thanks again. Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted July 25, 2007 Share Posted July 25, 2007 Why muck about - drop a 5-speed in. Series boxes were never designed for more than about 60bhp. You can even keep it 2/4wd with an LT230. Quote Link to comment Share on other sites More sharing options...

CR88 Posted July 25, 2007 Share Posted July 25, 2007 The Santana gearboxes are usually stronger and are a good choice in mine honest opinion. But is already a 5 speed gearbox? If it is the 5 speed gearbox is mandatory to modify the chassis and propeller shaft. Because it is longer, even by a small distance, with the frame. I never drove any LR with this gearbox, but the opinion is always the same. Is very stronger and reliable but a little hard to use it. Another point when dimensioning a gearbox is the torque that is taking in account and not the power. If you increase the power of your engine will only get hotter the oil.

FridgeFreezer Posted July 25, 2007 Share Posted July 25, 2007 Unless you have a SWB and Mr grinder and Mr Welder have to come for a visit! Didn't say it was bolt-on, but it's doable. Looking at the layout on mine (109) I reckon losing 21" out of the drivetrain should be pretty easy, and that's with the long V8 bellhousing. I have a good 3-6" space in front of the engine and a long-ish rear prop, that's with a Series front end and PAS. Quote Link to comment Share on other sites More sharing options...

I believe the difference in the suffix D setup is a larger front layshaft bearing and larger intermediate shaft. Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted July 25, 2007 Share Posted July 25, 2007 Bearings and shafts are the same sizes as earlier. The drive dog teeth/syncros are machined so that under load there is a ridge to ride over to come back out of gear. Quote Link to comment Share on other sites More sharing options...
RPR Posted July 25, 2007 Share Posted July 25, 2007 KB, My Series box, of indeterminate suffix, has held up to the V8 so far, so why not check and service the SIII box while it's out/accessible for the engine swap and stick with it until it goes boom. Even then, a recon box is probably cheaper than buying a Santana Series box or doing an R380/LT230 conversion.... Quote Link to comment Share on other sites More sharing options...
Tonk Posted July 26, 2007 Share Posted July 26, 2007 a lt77 with lt230 into a 88 is easy doable, cutting and welding is required though. not particularly expensive if u pick up a cheap lt77 with worn mainshaft and rebuild it yourself Quote Link to comment Share on other sites More sharing options...
