Shoota's R33 GT-R RB30/26

[Shoota_77]

Yeah bush was $40, 3rd gear $131. $180 all up delivered from Amayama.

That's one snazzy looking workbench!

? Isn't it ? Yep just a raised up pallet, so something you can put the centre plate on, have the long front sections of the shafts pointing down while you're tapping them out. Easier than trying to tap them out sideways when the centre plate and geaset is mounted in a vice.

Finished the teardown and rebuild on the old man's box and transfer case modification yesterday. A photo I thought you might find interesting proof of why not to use any smooth shift additives or anything but GL-4 oil in a GTR synchro box. This is a synchro from 1st, it is completely stuffed and has been attacked by incorrect oils being in the box. Nulon and Penrite additives are terrible for doing this. The new one is the shiny one obviously, and the discoloured one actually has some parts of the synchro teeth missing also.

 

The gear also had a lot of synchro teeth missing, all stuck to the box drain sump plug.

Holy hell, that's mangled!

A few minor updates.

New 3rd gear and press on sleeve finally arrived from Amayama. Corona making a (unt of itself again...

Front diff should be back in a week or so from the dude who is resetting it in the sump for me.

I tried BK's method of removing the shafts from the centre plate and had mixed results... The counter shaft went from staying in place after 20 hits with the dead blow hammer to launching itself out and smashing into the synchro on the mainshaft and smashing it in half ?‍♂️.  I decided to keep trying with the mains haft but ended up destroying my dead blow hammer which disintegrated in a shower of ball bearings and metal dust..   BK, you can stick your bloody method! ?? 

Went back to the original plan of modifying the press to finish it off. Seeing I bought the bloody thing primarily for that purpose I may as well use it!

I cut the deck in half then cut up some steel plate to weld it back together. I made it 120mm between each side which is big enough to fit the largest synchro on the mainshaft in between them.

I also drilled new holes on the middle of the deck to be able to support it from two points on the uprights rather than just the one. Seeing the deck is now wider it puts a lot more load on the pins. 

Cue more boring press modification pictures!

As soon as the mods were finished i threw the mainshaft and centre plate in the press and off it came with minimal effort!

Building my new mower shed next weekend so I can get my machining/welding/grinding shed up and running.  It'll be great to get all of that stuff out of main shed. 

Slowly slowly!

I can't believe you had so much trouble getting the shafts out ?! Anyway good to see you're progressing !

Yeah I dunno, it just had it in for me!  I'm not sure if it was because it was a pretty new gearbox??  Anyway, all good.  It's heading in the right direction now!  Once I get this shed out of the way I'm back into it!

Boring shed pic-

Ha ha, sorry they're all boring non car related posts lately!  Hopefully in a few weeks that will change a little bit......

Enjoying this thread, especially all the gearbag tip and pics!

I've got a noisy RB25 box, (whine in 1st and 2nd, when on/off power) planning to pull it down, hoping its just bearings. Threads like this are what make forums great.

 

Keep up the great work

[Shoota_77]

Hi mate, very kind words, thankyou.  I'm glad you're enjoying what is possibly the slowest build on the whole of SAU :).

I can feel the motivation juices slowly churning away again so fingers crossed I can start to get into it again.  If we end up going back to shorter hours here at work again (due to COVID) then there's a chance I'll have a bit more extra time to work on it again!

House is only 6 years old so renos are years away!

Ha ha, put in a pool for the kids or get a sequential.... Hmmmmm.

Sequential will be cheaper!

and less maintenance too, pool you need to skim, clean, scrub, chems, etc.

Samsonas, well just an oil change

[Ben C34]

Kids will swim in pool 15 times a year max once novelty wears off after first year.

 

you will drive the car maybe more than that a year?

This man here makes a valid point, you would definitely drive the car at least 16 times a year. So in conclusion, get a sequential box.

[r32-25t]

Kids want a pool, tell them to get a job and buy one 

[PLYNX]

Get sequential, install it and then drive kids to council pool/beach/river/pond/billabong in it !

Win ! Win !

[admS15]

Sau has decided, sequential it is then?

[Shoota_77]

Jesus that escalated since the last time I checked in ??.

16 swims a year versus no drives for 8 years. The pool is looking like the smarter option at this point!

I’d need to sell the car to afford either of them which would make one of the choices a redundant decision.....
