Sierra Power Steer Q

[brendan_h]

is the wedge just to put the vit box inline with chassie

[BlueSuzy]

I have been searching everywhere for a certain mill cutter at my work to do the job for in my own time after work. But i cant find it! I've only been here 6weeks..So im also pushing my trial period with doing my own jobs. even if in my time.....

So im thinking flat plate style. then try to find 2 uni's...Vitara uni's?? and no welding allowed... But i need to find the uni's first before i start the conversion. so its a 1 dayer not a weeker off the road...

I have another car but selling it. and if it sells im farked if it takes a week to do the conversion..

Brendan, you would know the answer to your question if you read this post through you tool.

I think a vitara uni works, or a sierra uni from the firewall end.

I cut the input shaft off of a trashed manual steering box, bolt the rag joint solid (remove the rubber) then use the short section of splined shaft cut off an old box to join the rag joint to the uni.

This is best done with a late steering shaft that's collapsable. drill out the plugs that set the length and it can be adjusted to suit.

No welding, all factory parts, works a treat.

magnifico! Going to price up another sierra shaft. or just the uni...But they will want to just sell me the whole shaft

[Gwagensteve]

Make sure you currently have a collapsable shaft.

Steve.

[BlueSuzy]

yes i do

in terms of the probably easier part of fitting power steer, would a vit serpentine belt be close enought to fit if using a vit pump mounted on a G13? Or do i really need to measure it up and look for one off something else thats a similar length?

[BlueSuzy]

Some have air con on the belt too.

Just measure with string when bolted up, and go searching!

There is belts all sizes, all types.

Make sure you can tension it also.

This is exactly what I did. Theres no need to drill out the plugs though on the collapsible steering shaft. To shorten it I just sat it on some timber and tapped it with a lumpy just enough to shift it a mm at a time. I've done this in and then when I added the extra uni I had to lengthen and tapped it out. Its still as solid as it was stock.

[BlueSuzy]

ok. im going to have visit my wreckers once again.

Would the spline on a toyota box be long enough to cut it off to use as a spacer spline? And the toyota uni's? Cheaper 4 me thats all.

The suzy wreckers here will want to charge a mint for me to destroy a box spline..Where as this other on is mega size self-serve..

[Gwagensteve]

Cut the spline off of your manual steer box?

Lots of sierra manual boxes are stuffed now- they're out of adjustment. Shouldn't be impossible to find one that's not worth anything.

Steve.

[BlueSuzy]

I want to keep my box just in case something goes completely wrong for the moment.

[Hybrid]

Soft! Cut that bitch up!

Its a pretty straight forward sytem. I don't see how you can stuff anything up. Even if you can't get the pump sorted straight away the power steering box still works like your manual one. It will just take a bit more to turn for the time being.

[BlueSuzy]

Why am i soft hahaha. Went back to my suzi wreckers this morning.

Asked for a sierra uni and some shaft..The old bloke goes u again! Didnt we give you the vitara shaft!?!?

I said NO?!?!?

The vitara shaft for powersteering have a 2 uni's and a rag joint on the box side one.

The uni that is bolted to the rag joint, it is similar 2 bolt style!

But the bolts centres are different to the sierra. will have to make a small round plate.

EASY. No cutting up

[Hybrid]

Nice work. I thought I got my uni from a vit. Guess the splines are right on at least one of the vit models then seeing as you've had some luck.

and did this work out, blueSuzy? i'm looking at one now and the vit uni at the rag joint end has a bigger shaft. ( came out of a 2lt) was yours the same. secondly, even with a small round plate there will not be enough room for the nuts because of the larger diameter sierra shaft. the only other option i see is to swap half a uni with the other end to end up with the same spline size. this looks like a pita too cause the unis are peaned not circlipped. looks like i might have to go the stevie method.

[mr green]

yep, just did the stevie method. will swap a steering box out of my ute tomorrow ( the most buggered one i have) and do the spline chop. looks to be the neatest way i can see to do it, however you do loose over 4'' of callapsability. hope the engineer doesn't mind

[BlueSuzy]

Mine has been going good. But with heavy loads the pump seems to give up! Unsure. I should look into the pressure mod.

Vitara's have a slower ratio box too, unlike sierras box.

I used an adaptor plate(un engineered) It was alot of work though to get the plate as far up as i could. My diff is 25-30mm forward.

I used a 1.6 vit efi model, i think..It had no engine. Carb should be the same also. Unsure about 2L models.
