question on the teflon seals on the input shaft worm gear.....

putting those white teflon seals on was a BEAR ...heated them in hot water for 30 minutes before stretching them over the shaft.

they are on but are stretched a bit so there is some side to side movement. this is preventing the input shaft from going into its
home position in the case.

how long does it take for these seals to return to their "normal" size? is there anything to do here but wait?

 

I just wrapped the teflon seals with a plastic bottle (split so it will tighten) and then used electrical tape on the plastic to apply constant pressure.

now to wait for 4-5 hrs...

 

well, looks like I screwed the pooch on the o-ring install on the worm gear. they will not set into the groove. the original ones that were on the worm gear broke/got damaged
when removing...so there is no going back with them on. the dimensions of the o-rings are:

ID: 1.36"
OD: 1.54"
Width: .09"
Height: .09"

There IS a groove in the center inside of the o-ring which I'm told is used by the hydraulic pressure to keep the o-ring compressed against the case and prevent leaking. The
kit supplied (allmakes) has white colored square cut o-rings that do not have this groove. I believe this is what is preventing them from seating in the groove. so, I need to get
the PROPER ones.

Note this is from a GE 6570000 steering box which LR used in the 03/04 model years.

Anyone know where I can find replacements? I've asked RimmerBros for info on the Genuine LR kit to see if they would provide measurements for me and confirm they have
the groove style ones in their kit.

UPDATE: Rimmer bros DOES NOT carry the Genuine Land Rover item anymore either. So, from my searching there are NO Genuine QFW100140
kits available anymore unless someone has one in their tool bag. Anyone care to share?

I THINK I know what happened here on my install. The supplied o-rings in the aftermarket kits are square cut teflon units and DO NOT have the groove in the underside.
The channel that they sit on the worm gear has a round snap ring embedded inside. I THINK (anyone know for sure) you have to remove the snap ring from the groove
BEFORE installing these aftermarket teflon seals for them to sit down enough to allow the worm gear to fit in the case.

I appreciate any info from those who have gone before me.

 

OK, i believe I have found the issue. the metal ring UNDER the o-ring (the original teal colored one) was causing the square cut white one to not be able to go far enough
into the groove. This prevented it from going into the case. I removed the spring and took one of the surviving white ones and put it on...wrapped it with black tape for 30
minutes to make it "set" into the groove...lubed it up with fluid and it went into the case with not much fuss.

 

found a source on the interweb for square cut o-rings to match the original o-ring suitable for use in a PS box.

I googled who the distributors are in north america for Freudenberg (who make the kits for Land Rover). They didn't return my
emails for a quote.

Once I found who the local cats are (tampa)...called them and they had stock next day for the Quad series o-ring suitable
for power steering box for fitment on the worm gear. stock #: 126 on product chart. Company I sourced them from is
Wyatt Seal.

 

I received the 6 quad o-rings.....got them installed onto the worm gear....does not look like they are gonna work. Too tight. Binding.
over 4 lbs of force required to move spin the worm gear in the case WITH NO PRESSURE on the big nut on the end. the material
of them I think is binding in the case. friction. so....I think I'm going to have to find the viton material ones. grrrr

I just removed the worm gear/input shaft from the case and removed the 3 o-rings and carefully inserted the worm gear again.
This time, smooth as butter. Little to no resistance....so it would appear the o-rings are binding.
