I know I can find these on my own but everytime i think I know what I want/need and I ask here i get a better answer. Soooo

Brake lines in flexible SS that are metric on one end and SAE (I hope? whatever a series rover is) oh and they need to be LONG.

Vacuum stuff. what is typically needed to engage a vacuum locker? (again ZERO experience rearing its ugly head). I figure a series gets about 20lbs at idle.

Ok,

Now I had a idea :idea: Lets say that C303s have something other than a 2"x2.25" flange on the pinion, could I take a flange and take off the rover flange off the end of the driveshaft and use a different flange on the U-joint?

Do not fall in to the vacuum trap like all the new POS 4x4s with a vacuum engaged frt axle. Ever seen a jeep munch it's frt axle because of a vacuum operated frt diff?

Your on a long steep hill climb and the pedal is on the floor, your vacuum goes to 1-2" and your forward progress slows down because your now in 2wd. You let you let up on the peddle and try to regain traction. Vacuum returns and slam,bam pop goes your front diff!

There are electric vacuum pumps and alternators off of diesels that have one built in.

Nevermind on the flange:

Just got this from the malaysian people:

"hi
ok you want to fix portal to 88.you got to change the sring mount or re weld it's position inwards.The long shaft flange is the same with land rover.rims are important and the locker valve. "

Now whats the locker valve?

Ron

Humm,

electric pump on my poor Noah. dimm, flicker, and off. Any idea how one physically works? Could it be converted to air or better yet cable. How about a vacuum tank, how would that work?

Scroll down and look at the pic with the discs. They did something to it.

Getting the vacuum shouldnt be too hard. Maxi drive lockers run off vacuum. You should just copy what they do cause I have never seen them have problems.

Sam

ps great looking axle. I like the way the steering joint is before the portal reduction. Right where it should be. What sort of joints do they run - CVs???

They run cvs and have 27spline axles. 2.1:1 in the hubs. Beastly but not as beastly as a Mog axle. Then again you can't use stock driveshafts with a Mog axle :)

What does maxidrive use? Got any pics?

Ron

Ill find out how the maxi drive set up their vacuum valving this weekend cause I will be wheeling with a couple of rigs that run them. (I will also take some pics of that series 3 ute cab as well)

Sam

Ron,

On your question about the "locker valve" I replaced one on my Volvo C304. Its a simple valve made of plastic which you can twist a quarter turn, and works like this:

Open: Vacuum goes thru valve and operates the diaphragm at axle to engage.

Closed: Vacuum is shut off. Diaphragm side is vented to atmosphere so locker can disengage.

If you can't get a valve that works like this, you can easily modify a simple ball valve to do the same thing by drilling two holes. One thru one side of the valve ball, and the other thru the body of the valve. Easier to send you a sketch. If yo need one, holler.

Regards

Forgot to mention that I have a small 2 litre vacuum tank for the lockers as well, and haven't had any problems with it disengaging... yet!

On your question about having the lockers actuated by a cable, the axles shown in the extremeaxle site look cable actuated. I say this because the vacuum diaphragm assembly isn't in the picture. All you see is a cable going straight into the diff, which is where the hockey puck sized vacuum actuator sits.

Regards

One more thing I forgot to mention (great way of increasing my posts huh?) about vacuum loss... I don't notice any on my Volvo which is in its original configuration except for the extra vacuum tank.

Just make sure you have a one-way check valve installed just after the intake manifold, before the vacuum tank, and you won't have any vacuum loss at wide open throttle. If your actuator valves and diaphragms are in good condition, and the hoses properly clamped you have no worries. In fact as a test, I could engage and disengage both front and rear lockers about six times, five minutes each time, with the engine off. I know, I should get a life!

Hope this helps.

Steve the post whore!:flipoff2: :p

Five posts compared to 5000!?? ;) Now who's been getting around more? :D

Sam, what the fawk? You can't go wheelin' this weekend, you're supposed to be taking picts of the drilled bushings! Damn, I'm never gonna get my shiat done! :flipoff2:

I only get around once more per day than you. As a rookie you learn fast!:flipoff2:

getting back to the vacuum question...

Red Dot and Hella make aftermarket electrical vaccum devices, as does WARN (but I think that theirs might be made by Hella...), so you could start looking that route instead.

Might be nice to have it NOT operated by the engine.

Just a thought. I can dig up catalogs and part no.'s if you want 'em.

Later,

Michael

yea I know. But today im on it and by tomorrow I should have some pics. The wheeling bit only takes a good half day. (unless someone gets really stuck :flipoff2: )

Sam

Welcome Steve :flipoff2:

I dont know many Steves let alone any from any from Kuala Lumpur. Great to have you here.

Dont suppose you know a Ralph that has a series 1 hybrid????
Hang on heres a pic.

Sam

Thanks for the welcome Sam and Michael. I had a different sort of welcome from Old Scout yesterday and was blinded by his math:flipoff2:

Dont suppose you know a Ralph that has a series 1 hybrid????

Sorry I don't, but it brings up an idea I had while up in Cameron Highlands last weekend (home of 3,000 Landies that pay no road-tax and work the farms and tea plantations)... can I put a S2b Forward Control Cab onto a S3 88 chassis? The FC cab was going for US$250, and I can get a running S3 88 for around US$2K. If you guys think its possible, then I'll start another thread.

Back to topic, I'm not a Landy owner yet. I'm only here to try help one of you guys with the 303 portals since I have a 304 (a tonne more capacity than 303) I just happened to see Ron's post on the Malaysian Land Rover Owners site and tracked it here. I think I've gained more than I've given!

Regards,
Steve.

Hey Steve :flipoff2: :flipoff2: welcome

AS far as the FC cab on an 88, Ive seen some pice of factory testing that was done way back, and as I recall, it was pretty dicy under hard breaking when coming down a hill. A 109 would be a better candidate for the FC cab IMO.
