I am working on a air locker for the vw kombi diff but before I go any further ,I would be interested to know if any one knows of a diff lock that is off the shelf already ?? so far I can not find one any were ?
I am not sure on the ( if there is a strong market for these ) but will build mine any way .
mmm thanks modulus , I knew I seen this some were ?
I have just stripped my mates holden HSV diff down HYDRATRAK thing , mmm what a heap of SHIT this car is thye rear end has fallen out 4 times any way ,the hyra thing a like a detrot locker no more , after I got it out ,and he left to get lunch .I decided to cut it open in the lathe , got a cuter $70.00 ground it to a V turned all the power off in the house ,max amps ,and started to cut it open ,I found that when they wear there is no were for the filings to go bearing bronze ( sealed from diff oil ) it has a hi temp grease that is packed in and sealed off .
I then looked at the kombi diff .I think I can fit this to the center a bit of machining a adapter ( spline ) a few mods and it will fit .
But there about $1300.00 so thats out .
The option your ref to is better .
look for the HSv with out a hydratrak at the car yard ! holden drive on !

This has possibly been thought of or even talked about before, but how close is a Subaru diff to a VW???
Is there a Air Locker for Subaru available(That could be modified)?

seagull, you make..........me buy !
seagull ·
I started it to day patent pending ! graig , O did you get the photos I sent you ?? seagull
Andy42 ·
I am with craig you make I BUY:thumb:thumb
Craig Torrens ·
got the photos,thanks...........................now start working on the diff !!!!!!!:thumb
P.S. I'm using a 1800 Kombi box. :kiss
seagull ·
man the pressure to get these is on ,now to find some HSV up side down in the bush !
Craig Torrens ·
that can be arranged!:P.................................tell me what you need.
seagull ·
There easy to um borrow just ask the kids at the loly shop !
Craig Torrens ·
what about a normal Holden LSD???
Brad ·
I'm with these guys, I am using a 091 box though and would like to use the 4 spider diff from the later transporter.
But you make and I too will buy if teh price is right :>
daz67 ·
Me Too.
You make and I too will buy if the price is right :>
Craig Torrens ·
Sounds like a group buy seagull !!!!
VWCOOL ·
I'll be in on that, too. BUT take a look at the Lock-Rite (mayby lock-right) diff. They do a centre for the BTR diff (Falcon, Commodore etc). I'm sure they have a diff for the Kombi box. Not sure about Beetle
seagull ·
craig , I have not seen the holden LSD ,the locker hydratrak is a mini spool small .I need to get hold of the following 2ltr kombi box , 1800 kombi box pdf format of the crown wheel and pion then run the holden pdf over that , with some help mabe here this may pay off .I would say if it works it would be a very good set up ,the hydra can be split opened and the shims replaced ,then rewelded ( dont tell the holden boys ) so need to get them first before they go in the bin .a air locker may be the go as well ,
but re this , my mate has a nissan 720 twin cab 4x4, nissan v6 he has fitted a air locker to the rear he was showing off smoking the rear big bags when he seen only one wheel was smoking he hit the switch ( air pump ) BANG the diff blew up . not smart .the other point when going hard ( oil temp ) is up they leak air pass the o ring seals you see hear the leak from the oil breather tube and when the car is in a standing position the pump runs ( no leaks from air lines )
Brad ·
if it isn't going to be a command locker of some type there is no point as an auto locker and spool is already on teh market, as is an LSD.
seagull ·
yep ,but the cost ! is_____
Brad ·
Ok I will reword for ya .. 🙂
I am only interested in a Command Locker as I like steering my buggy when I drive it. So if it is going to be a auto locker, spook, LSD etc etc then I am not interested.

Yeah I think in a Buggy the diff of choice is a command locker.
I think Vacuum Hypoid style Diff-Lock would be the best style as that way you don't need an air compressor.

Talk to "Country" Rod Hatters old navigater they put a ford 9" into a 2lt kombi box ( it could take 300hp).

Interesting. I notice on their site it says (about the vacuum locking carrier)
"The Vacuum Operated 4 Pinion Gear Locking Differential Carrier (pictured), can be manufactured to fit most conventional automotive Differentials"
and
"If you are interested in this Differential Lock Design for your vehicle - please contact us. "
I think someone should contact these people. They obviously have the CAD drawings of the carrier, if we could get the drawings, then draw a 6-rib diff, then we'd be able to figure out if it could work. They might even already know.

my relation ! runs these in his sand dune hill climer SWB jeep runing a super charged 351 v8 . I think this is what they call quadratrak ? not 100% sure .I do know it is vacuum operated
Chris the diff is totaly stuft after a race ! it wares the diff out I know a lot about this box and it good and bad points .the man is a legend amasing its made from a scrap plate and some old steel bar a old renault some old holden bits
.I had a look at the clutch after max raced it last .man it was just holding on ,fast car and big $ .
I worked it out a few weeks back for every 3 kmters you need to throw $100.00 out the window ,thats what max does .
pete wood ·
The idea looks great. I'd be interested in knowing if he can do one and what it would cost.
What do you reckon it would be like for the odd night at the drags?
Baja Wes ·
I reckon you don't need a locker for the drags in an offroad vw. I really really doubt you'll get any real wheelspin anyway.

Has anyone looked into the syncro vaccuum operated diff locks?
seagull ·
I looked a vacuum locker to day and its in my shed ! there is spool with a fork that pulls the dog gears in .It has never been used as the guy did not know what it was for ? now to get it in the diff center
dubcab ·
If any one can make a switchable diff-lock I'd certainly be interested. I was talking to a guy a year ago in toowoomba at the klub vw show,I think his name was rudy, he was driving a syncro with twin diff locks. He told me you can fit a l.s.d. or switchable lock to earlier kombi's but.....the cost $2500 and $4000 respectively. For something your going to use about 5% of the time its a bit exy. $1200 buys a bloody good electric winch. So without sounding like a tightarse an affordable diff lock option is what I'm after.
KruizinKombi ·
I could have used either of these on Monday.... got stuck chasing goats alongside the road (its a long story). The point is, I could have walked out of this no probs if I'd had a locker or LSD fitted....
seagull ·
Do you think so ! looks like a big hole
11CAB ·
Here's a pic of the vac locker in the locked position
11CAB ·
and unlocked
11CAB ·
So who has a CAD program and CNC machine?? Looks simple enough........
seagull ·
yes I wish I had one I would be there now making them .This one is from a vw ? and what box ?
11CAB ·
It is a factory VW locker from a T3 Syncro.....091 side shift trans.
Graham
MickH ·
How available are the side shift 091's with the locker???? Why not just use one of these and convert it to a "normal" shift??🙂
seagull ·
yep may be dont tell every one but ! who has a cad pdf format .I need to have a look .
Boozer ·
any update on this???
seagull ·
No I sold the gear off due to
time
$
I dont think any one would pay for it any way .
The air locker has lots of problems its in the O ring seals , diff temp goes up > air leaks out the diff breather , have seen them all and repared most of them .
I still working on the HSV holden one , so if you see one stolen in the bush , go your own way , if you get my drift 😉
Flintstones ·
Seagull,
Any progress on the HSV diff?
Cheers
seagull ·
I have done some work on this subject but due to two of my projects needing finishing have placed it on the back burner .My next project will require this set up so I will post it here when I have some work in progress shots .
Keep your eyes out for a 215kw holden parked on the side of the road !

.The unit when made is two halfs ( wave plates ) with the slides placed in the center then the uint is welded together with a tig , it filled with a high temp grease then sealed with a small bearing .
The problem is when the ( bearing thrust washer ) wears .The fine fragments have no where to go .The slides then are pushed into the center and do not drive ( lock ) each wheel .This then calls for the car to drive only one wheel or two as it may slip and find lock for a second then back to one wheel .
I have made a cutter for the lathe as to open the center , when I did the fist one I thought the center was filled with a coppy type grease ! then found it was small particals of the thrust washer .
I am going to see if I can get some thust washes made so I can repair the center , then return it to service in a VW diff .
The unit is over $1000.00 new or you may find one in a bin at a diff place like I did the other day .
seagull
Flintstones ·
if you manage to get some washers, ls there a way you can modify the LSD so this won't shorten the life of it again?
Cheers
seagull ·
I would say no , it needs to be cut open for repair each time .
After looking at this tonight I will not follow doing any mods to make it fit the vw diff .

try these guys at Modena Engineering I find them very helpful 0397824420 or 0397825273 they custom make gears all types of diffs might help.
