Lokka fitted

[manora]

I can get to the site but it will not let me scroll any further than 09 and "A" almeras etc, some times it will not load at all, could it be my browser Google Chrome.

Glad you got your shims sorted Manora, result, you should be OK on 144 but was that with the casing bolts torqued up? Rick

I use Iron, a derivative of Chrome, and it's fine. Maybe some setting you have in yours.
The gap was pretty much the same after torquing down and I bench tested again after it was all back together, fingers crossed it tests ok on the car.
I've been trying to work out if a smaller gap is better or not but can't really come to any conclusion.

if the gap is too small it cannot unlock completely, if the gap is too large it cannot lock completely, Rick

Well, it’s been busy day. The diff has been in and is now out again.

Got the whole thing back together this morning and tried the required tests.

Not good The Lokka won't unlock as it should although it did try a couple of times. Maybe 144 thou is just not good enough, I thought, so back to the spanners and out it came again. Much faster this time, I'm getting to be an expert :thumbs.

Upon inspection I found that the gap was still measuring at 144 but I decided to recheck everything from the start. When I measured the drill bit I use as a gauge my electronic vernier showed 135 thou first time around now it was showing about 137. Out with the micrometre, should have use it from the start :doh, and it in fact measured 140 which was confirmed by my trusty manual vernier. A few more comparisons has proved that the electronic vernier is b****red and is now heading for the bin.

Anyway, to cut the story short I actually have 145.5 thou, average of two sides, gap and it seems it’s not enough although it is within the recommended range.

The good news is that the nice Nissan parts man rang today to say the washers I ordered will be here at the end of the week. They should be about 30 thou so it will be more grovelling to the nice toolmakers for a go on their surface grinder. Down to 20 thou each this time, should give me about 155 thou gap, bang in the middle of the range.

Hope springs eternal

Once you've sorted the bolts on the front crossmember its pretty quick, as long as you don't have a sump guard to remove as well.
Bit of a fiddle getting the rear crossmember back in place, it's about 3/4 inch wider than the torsion bars and has to go in one end first.
It is heavy though, I have a motorcycle lift which is ideal for lowering and raising it into position. No way could I lift it and wiggle it around and get bolts in.
I used to do it with gearboxes but I was a lot younger then.

I see

Doing my oil and filter tommoz, so will have a good look at it whilst I'm underneath to see what holds it in

How did you do the on vehicle unlock test????????? did you have a mate if not exactly how did you do it, Rick

I have a wife who used to me making strange requests for help and I did the test a per the fitting sheets.
With the gearbox engaged it refused to unlock in either direction however with the gearbox in neutral it seemed to unlock ok. They make the point that all should be as per the test so I decided to start again.

I have one of those.... No tool box is complete with out one...

Mind you, bleeding the Clutch did her head in for a while, especially with the T2's habit of leaving the clutch peddle on the floor, and needing to lift it back up with your toe...:lol

interesting, at 145.5 you should have had enough clearance, I must admit I did my test on my own, I used a 3ft knuckle bar on the near side wheel nuts and stressed it in reverse with axle stand then turned off side forward and it slipped once then locked as the strain was relieved on the near side, but test proved, did the same for the following 3 tests, how is yours now you have assembled it again?

It's still in pieces while I get the washers reduced some more although I may have to wait until the new ones arrive and I get them ground to size. The original ones are a bit distorted now after they were ground.

This Lokka is driving me nuts, Worse yet, I'm driving my dearly beloved nuts as well.

I now have about 158 thou on the critical gap, well within spec, however I cannot get it to unlock correctly as per the instructions

I'm going to ring 4WD Systems in Oz for advice, when they are out of bed, cause I'm not happy fitting it again until I'm sure it's right.

Maybe it's me but nothing seems to quite go the way it should

when you measure this gap are you doing it with the springs and pegs in, I did and also I measured opposite sides at the same time cos I found the things cocked slightly so giving a larger reading than it should till I balanced it with a drill and feelers opposite, Rick

Exactly according to the instructions, springs and pins in, two drills/feelers and an average reading.

I've just refitted and tried again and get the same results as before. With the gearbox engaged I get no unlock, with gearbox disengaged I get perfect unlock in all parts of the test even though the prop shaft doesn't actually turn, just rattles a little.

Just taken it for a test drive and with manual hubs locked and 2wd there is maybe a tad more self centreing on the steering but not an issue at all.

I haven't had a chance to try properly in 4wd but I did put the 2 nearside wheels in a muddy ditch and it just drove out with a slight wheel spin from the offside front. I also, for the last few yards back home, put it in 4wd on the road and turned into my gravel drive way, very strong self centering and no sign of it unlocking on the turn onto the gravel although with such a brief and unsuitable test I can't really draw any conclusions.

Looks like a late night/ early morning phone call to Oz.

You can say that again, if I didn't have such a cheery sunny personality I could get really depressed and it's blowing a gale and pouring down here NW Wales.

I'm going to call at about 7 in the morning, it will be about 3.30 where they are and it means I don't have to stay up late and have a good nights sleep.
