Hi All,

I am converting a r33 gtst from auto to man. I am having trouble getting the auto spigot bush out.

I have tried using the wet newspaper with a bolt trick but its not working at all.

Has any body got a spigot bush puller they can lend for a day, I really need it out as its holding me up.

Also, anyone got any other techniques.

Cheers

Daniel

Had the same problem converting an auto Stagea engine for a manual box in my 32. The usual method is to fill the hole with grease, then punch a gearbox input shaft into the hole.

However, I ended up resorting to a wheel stud tack-welded onto the bearing, then use a drift hammer to pull it out.

I have tried the equivalent and to no prevail.

The wheel stud you used, was it a perfect ft into the bush or was there 0.5mm - 1mm gap give or take each side.

Cheers

Don't remember - it was 3 years ago, and I'm suffering advanced dementia :laughing-smiley-014:

It doesn't have to fit - the weld will bridge the gap.

sorry to ask a dumb question....but why would an auto have a spigot bush? what sits in it?

I assume its in there for the torque converter and this ones a steel item it doesnt wear down, where the manual bush is brass and slowly wears down overtime. I think this is correct :down:

normally i use grease, but if you cant find a perfect fitting bolt to bash in there try using blue tack.

hasnt failed me yet. and also doesnt destroy the crank if you miss hit with the chisel idea from above..

I had another go at it today. Went to the bolt shop and got almost a perfect match for it..still wont budge, the newspaper keeps pressing into the thread.

The glue tack idea sounds good. I might try some grease instead of the wet newspaper too.

For mine I went to the local hardware and bought a suitable size bolt (like 16mm or so as mentioned before), CUT the thread of the end with a hacksaw and cleaned up the edges with a file, then filled the back of the crank with grease and gave it the FBH (f@cken big hammer) approach and it popped out easy as. The bolt has to be a tight fit - ie you have to hit it in with the hammer, and after a short amount of time it came out easy as. Cost me a couple of dollars - tried heaps of other methods before I finally gave this a go - was completely suprised at how easy it was. You then can keep the long bolt 'genuine spiggot bush remover' in your box of tricks for next time. As they say - the right tool makes the job easy! Good luck :-)

you sure the brass bush doent just fit inside of it? i dont see the point of having a bearing for an auto when the crank and torque convertor dont turn in each other unlike an input shaft of a gearbox. ive converted an rb30 auto to a manual and all you have to do is fit the bush

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
