western Posted May 13, 2019 Author Share Posted May 13, 2019 or leave existing sensor in place & use this to switch manually speed sensor/control box override kit got one on my recently refitted OD & it works fine. scribbles are mine.

Oakmaster Posted May 14, 2019 Share Posted May 14, 2019 Yes! - so in 4 years we have not made any progress on that front! Oh well! I will try the relay and the reversing switch approach. was your kit from Devon 4x4? - I wonder if anyone has worked out how to make the LED in the gear knob work to show if it is engaged? if not I could put a bigger brighter LED on the dash. (forgetful moi?) Thanks Ralph. B 1 Quote Link to comment Share on other sites More sharing options...
western Posted May 14, 2019 Author Share Posted May 14, 2019 Yes my kit from Devon 4x4, the led I think can be wired into the switch, so it lights when switch is operated to engage OD, I've been thinking of doing it to my gearknob led. 1 Quote Link to comment Share on other sites More sharing options...
western Posted May 19, 2019 Author Share Posted May 19, 2019 On 5/8/2019 at 4:57 PM, western said: It's getting better with use, most likely the new clutch parts beginning to bed in, I'll check the fluid level on friday & have a good look around for any leaks, but haven't seen any telltale spots on the ground. I'm happy with it & my 110 seems a bit queiter even without OD engaged. Well, done a long drive to Wiltshire & back this weekend, OD was fine on the main roads/motorway doing exactly as its meant to, BUT on local roads with it disengaged & sometimes when disengaging it would not disengage cleanly & I had a few occassions of unwanted slippage & taking to long to disengage which meant loosing road speed too, fluid was topped up on before the long trip, going to get some more fluid & change it during this week, may also drop the circular filter & clean it with brake cleaner & fresh ATF before refitting it, if that doesn't stop the unwanted slipping, it'll be removed & stored in garage until I can afford a Roamerdrive unit.

western Posted May 19, 2019 Author Share Posted May 19, 2019 Just been & checked fluid level it was approx 50ml down from dribbling out the fill/level hole, but no sign of any leaks on outside of the unit. Quote Link to comment Share on other sites More sharing options...
western Posted May 20, 2019 Author Share Posted May 20, 2019 Tried to drive this morning to go to work, virtually no drive at all, crept out of the drive & down the road, OD slipping a lot, only gripped for about 30 secs, so turned around & came back home, very slowly into my drive. Makes 110 undriveable. 1 Quote Link to comment Share on other sites More sharing options...
reb78 Posted May 20, 2019 Share Posted May 20, 2019 I would be tempted to replace the broken part in your old one with the necessary bit from the new one Ralph. The one you have has had a lot of other new parts (inc clutch) so will provide spares moving forwards for you too. Quote Link to comment Share on other sites More sharing options...
western Posted May 20, 2019 Author Share Posted May 20, 2019 About To go out & remove it all & refit the original transfer gear, only early shift this week so need it to go to/ from work, My previous OD is in bits in garage & needs gaskets, seals, filter changing if I decide to refit it, haven't got the it's or time to play with it until the weekend Quote Link to comment Share on other sites More sharing options...

western Posted May 20, 2019 Author Share Posted May 20, 2019 Got to have 110 on the road for tomorrow morning to go to work, Just dropped the oil it is black, a few drops on a clean rag, only done nearly 500 or so miles Quote Link to comment Share on other sites More sharing options...
western Posted May 20, 2019 Author Share Posted May 20, 2019 Some sludge on inner face of baseplate I cleaned this & the filter with brake cleaner before fitting. Could be gummed up inside, but a strip down will have to wait until the weekend Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 20, 2019 Share Posted May 20, 2019 That's not good for 500 miles, but then if it was slipping.... You will toast it very quickly indeed, much like an autobox without the kickdown cable connected. Quote Link to comment Share on other sites More sharing options...
western Posted May 20, 2019 Author Share Posted May 20, 2019 All removed now & on bench, original gear refitted & all good for going to work tomorrow. Will pull the OD filter either tomorrow evening or at the weekend. Quote Link to comment Share on other sites More sharing options...
V8 Freak Posted May 20, 2019 Share Posted May 20, 2019 Sorry to see this Ralph.... After new clutch / brake material, springs, filter and spragg clutch it was behaving itself until it ran low on oil. As I explained before, we only discovered the oil leak once we made camp that night and it was taken out that evening. It wasn't slipping all the time.. Only on a few occasions but once we discovered the leak it was safest to remove it.... It sat un-touched in the box as you got it for two years.... I believed it to be in good order but didn't have any vehicle to fit it to... 1 Quote Link to comment Share on other sites More sharing options...
western Posted May 20, 2019 Author Share Posted May 20, 2019 No worries, going to remove the big filter tomorrow if I can get the cap off & give it a good clean, actually looking inside from the bottom plate it looks quite clean, didn't have any big bits fall out when the bottom plate was removed.

V8 Freak Posted May 20, 2019 Share Posted May 20, 2019 If you're going onside, here's a pic of the brake / clutch material for comparison to new... And the obligatory pic of the new spragg clutch.. And springs... Might be worth checking the piston that generates the oil pressure? I'm assuming it needs oil pressure to hold the brake / clutch material into the Overdrive position to make drive go through the planetary gears? (Effectively the cone is a brake not a clutch) Or do as Rich suggests and build one from the best parts of both? Quote Link to comment Share on other sites More sharing options...
western Posted May 21, 2019 Author Share Posted May 21, 2019 No problem with the parts you changed, as they old ones are in the box, going to look at the filter first, hopefully my angle grinder adjustable key will get the filter base off.

V8 Freak Posted May 21, 2019 Share Posted May 21, 2019 I was only thinking out loud while typing Ralph.... Filters, springs, brake media, spragg clutch "should" all be ok.. So the only thing that came to mind was suitable fluid pressure to force the cone to act as a brake and route the drive torque through the planetary gears.... (If my recollection is right, spragg is only really a reverse safeguard!) Therefore if filters are clear it could point to potential wear in the pump mechanism?

reb78 Posted May 21, 2019 Share Posted May 21, 2019 I dont think the filter will yield anything fruitful here Ralph - I think we tried it in Mo's truck and with a new one and it didnt help at that point. The springs seemed to make a real difference as it is these that hold the clutch in the 'off position'. When pressure from the pump is allowed through by opening the solenoid, the clutch is pulled back into the other cone and drive goes through the unit.

western Posted May 21, 2019 Author Share Posted May 21, 2019 Filter, relief valve & piston accessed, & some gunk removed from filter element, piston, springs look OK, Inside of OD looks clean too. Quote Link to comment Share on other sites More sharing options...
Snagger Posted May 25, 2019 Share Posted May 25, 2019 What is that? It looks like it could be broken up sealant. Was it you who has to encase the sensor in epoxy due to a broken plastic casing? Any of that on the clutch packs or in the solenoid system could cause slipping. Quote Link to comment Share on other sites More sharing options...
western Posted May 25, 2019 Author Share Posted May 25, 2019 It's not sealant, just black gunge, I haven't done anymore to it so far, need some more ATF, going tohave another look at it tomorrow or monday. Quote Link to comment Share on other sites More sharing options...
Snagger Posted May 26, 2019 Share Posted May 26, 2019 Any idea on its source? Whatever it is, if it's in the clutch pack, it could be holding the plates off one another or lubricating them. Quote Link to comment Share on other sites More sharing options...
western Posted May 26, 2019 Author Share Posted May 26, 2019 all that black gunk came out of the filter, I haven't opened the casing yet Quote Link to comment Share on other sites More sharing options...
Snagger Posted May 27, 2019 Share Posted May 27, 2019 What is the oil pump made of? Is it a fibrous gear like the LT77/R380? If so, it could be breaking up, and the reduced oil from a worn pump and blocked filter wouldn't help with the pressure on the clutch packs.
