Toyota centres

Post by **landy_man** » Thu Jul 03, 2003 9:39 pm

O.K. - done a search and I know I've seen it somewhere but can't find the post

What do I need to do to get toy diffs into my Rover housings...

I know this has been discussed before but can't find it...even on Pirate :cool:

tax refund on the way, so need to start making plans

Hilux diff centres front and rear.
Front diff from 80-100 series and some hilux diffs are high pinion reverse cut, worth fitting to front, helps with drive shaft angles.

Redrill the RR housings to take the Toy centres.

JacMac has the rear axles in stock. $650.00 inc flanges.
Jacmac makes the front axles to order. $550.00

Spindels require boring out 30 thou.
Pinion flanges require drilling to RR bolt pattern along with boring out centre slightly.

Reassmble.

Regards
Michael.

Worked for me

Landy man,
What ratio you looking for.

Michael.

Post by **landy_man** » Sat Jul 05, 2003 11:09 am

have not decided yet... most probably 4.88

why???? do you have some for sale

PM me if you do please

Post by **landy_man** » Tue Jul 29, 2003 7:41 pm

Okay...
So tax refund has arrived and am ready to convert.

Does the 80 - 100 series high pinion come in a 4.8 ratio ??

Post by **HSV Rangie** » Tue Jul 29, 2003 7:46 pm

available ratios.

3.42,3.54, 3.72, 3.9, 4.1, 4.3, 4.375, 4.56, 4.71, 4.875, 5.28 & 5.71

As far as i know.

80 and 100 come in 4.1 and 4.3.

Michael.

Post by **landy_man** » Tue Jul 29, 2003 7:49 pm

so if i wanted high pinion front I would have to go with 4.3.....

Post by **Bush65** » Tue Jul 29, 2003 8:21 pm

80 series are 4.1:1 100 series are 4.3:1

Post by **landy_man** » Tue Jul 29, 2003 8:36 pm

Ahh crap..... that means the 4.3 high pinions are going to be $$$$$$$$$$$ seeing they are from a 100 series...

might have to go lux centres front and rear

Post by **Strange Rover** » Wed Jul 30, 2003 7:26 am

4.3 high pinion must come from something else as well. This is what I got and paid about $400 (Im guessing here but it may have been only $200 and was definately less than $500)

Ill ask Ruff to check this thread cause he knows what come out of what and where to find it.

Bundera.

Michael.

Post by **RUFF** » Wed Jul 30, 2003 6:00 pm

Yes Micheal is right a lot of Bundera fronts were 4.3. You should be able to find these for around $400-$450 second hand.

Post by **landy_man** » Wed Jul 30, 2003 6:09 pm

beautiful..........
now just need to find a wrecker with Bunderas

Post by **DiscoDino** » Wed Jul 30, 2003 9:41 pm

So from which trucks did the 4.875, 5.28, and 5.71 come from, and are they weaker than the higher ratios? just like the 4.7 is weaker than the 3.54 on a rover?

Post by **POS** » Wed Jul 30, 2003 10:05 pm

Yes they are weaker!

The 4.88 would be the strongest out of the ones you mentioned!

The 4.3 is by far the easiest to find in HIGH PINION!!!

I have just priced some around Brissy ( for no particular reason :oops:

) and most are between $400.00 and $500.00!!!

Post by **Slunnie** » Fri May 07, 2004 10:26 pm

Talk about raising a thread from the dead. :roll:

If you were to fit hilux diffs to rover axles and you wanted the 4.1 ratios, then the R&P come from the front of the LC80. What gets done with the rear? Does the front LC80 R&P go straight onto the rear Hilux diff or are they reverse cut or whatever and perhaps not a good call?

Post by **landy_man** » Fri May 07, 2004 10:28 pm

the 80 front is high pinion reverse cut which is not a good idea in the rear -
the rear is a standard hilux item...
cheap as chips

Post by **Slunnie** » Fri May 07, 2004 10:30 pm

4.1 is Hilux? Oh.

Which ones?

Post by **landy_man** » Fri May 07, 2004 10:32 pm

not 100% sure as i was not chasing those ratios
i ended up going with 4.5 hp from bundera and 4.5 rear from hilux

landy_man...

I'll be going the 80 front - Hi-Lux rear and getting some custom (from the US) gears for a 4.88 set-up.

Couple of questions if you may:

1. How did you mate the Toy Pinion to the Rover Driveshaft?
2. I keep reading "re-drilling the Rover housing"...but I remember that the Rover 3rd member is the one that has the "holes" in (in Arabic we call ie the "female" side of the joint) and the axle housing having the studs (again, teh "male" side...shows how sexist this society is huh?). Can you please elaborate? any detailed pics would be great as well.
3. Is this is correct list of things (sorry to be tiresome)
a. axles - 30 splines, 1.31" (source: Jac Mac)
b. flanges [is there a Front/Rear difference] (source: Jac Mac)
c. toy Housing [80 front - hi-lux rear] (source: scrap yard)
d. ARB RD23
e. redrilled rear housing [30 thousands to fit rear axles] (source: DIY)
f. redrilled front spindles

Thanks AGAIN in advance.

Strange Rover Wrote over at PBB:
No mine wont. I will just machine the rover size shoulder in the flange and redrill the rover pattern. The length of the toy pinion is 3mm longer than the rover pinion so drive shaft length should be the same.

1. drilled holes in toy pinion flange to match rover pattern
2. you drill the rover axle housing to match toyota pattern...I knocked the studs out and re used them
3. almost.....the rear axles are the jac mac 30 spliners....front you still use the rover axle housing just fit the 80 series diff centre again with jac macs 30 spline to whatever cv you have so....
if you are staying with the rover cv's then only the rear spindles/stub axles need to be machined out to fit axles.....if you are going the longfield cv route then the front spindle/stub axle also need to be machined and a new bush inserted
the rear flanges are custom 30 spline to rover hub pattern
front flanges will remain the same if staying with rover cv's....if toy cv then new flanges required

Post by **mickrangie** » Sat May 08, 2004 10:14 am

also 1 more important fing that Landy_Man left out...

Lots and Lots of swearing, kicking... etc

Post by **DiscoDino** » Sat May 08, 2004 6:23 pm

Landy_man: Thanks a lot for the details.

I will be going with Longfields up front, and 30 splined Jac Macs all over.

Some more details if you don't mind:
1. front and rear flanges to suit Toy CV and rear 30 spline axles are the same? (reason being that I want to ship spare parts as well so eitehr 5 of the same, or 3 of the same x 2)

Mick...Swearing is part of the fun!

Thanks again to all.

Nadim

Post by **landy_man** » Sat May 08, 2004 6:44 pm

yeah they are the same... 30 spline flanges
i dont reckon you would have strentgh issues with them..they are tough

sorry the pics are a little out of focus

Post by **DiscoDino** » Sat May 08, 2004 6:52 pm

Landy_man...

Thanks a lot...NOW everything is crystal clear! I've already ordered the RD23s, and will be heading to the scarp yards for the 3rd members. Should be ordering the stuff from Jac Mac by the 15th of the month.

Any pointers you can share over and above the ones you have already...

Thanks

Nadim

buy another farked centre...pull the guts out...cut the top off and you have a template for drilling your holes

Post by **rick130** » Sat May 08, 2004 7:02 pm

(in Arabic we call ie the "female" side of the joint) and the axle housing having the studs (again, the "male" side...shows how sexist this society is huh?).

Nadim, we say the same thing

A question re oil levels with the high pinion diff.
Is the filler in the pinion housing, and if not, do people fit a filler plug higher up the diff housing to adequately lube the pinion and bearings, ala Nissan Patrol front diffs which hold something like 5.5 litres of lube ?
