Crank Pulley Installation Tool - Can Anyone Help? :)

I'm just wondering if anyone in the Perth area (I'm in Vic Park) has a crank pulley installation tool that I could borrow tomorrow? I will come and pick it up / return it, put a deposit down, provide beer etc :P

Or alternatively, know where I could buy one at a reasonable price to suit Nissan engines, either today, or tomorrow?

I have a really tight Ross balancer and I'm going to need a proper tool to get it on :/

Cheers!

Justin

You dont really need an install tool to fit the balancer on an RB. Its ideal yes. But not a massive requirement.

You can just use the bolt to press it on as it has a large thread. But it can't be too tight a fit.

The reason they have have those install tools is for engines where the crank pulley bolt is only a 10 or 12mm bolt and will not be able to press the balancer on.

When i was looking at doing this, i looked at buying the tool to do it. They were all a generic tool with threads, adapters etc to fit a lot of engines. However none came with the M16/18? shank to suit the RB25 crank.

In the end, i just pressed it on with the crank pulley, it was actually a walk in the park. Pressed on very nice and easily. Put anti seize on the crank and wound the bolt in then torqued it. Easy.

The interference fit was very close to ROSS' specifications though.

I'm not sure how out yours is? You need a telescoping gauge and micrometer to creaturely measure the crank and the ID of the balancer.

EDIT - If its too tight you can't fit it period, this was done by a friend of mine with his ROSS balancer onto his engine, he didn't have a care in the world for specifications or the interference fit. Needless to say, when it was time to get the balancer off, it was almost impossible too and the crank had been damaged from such a tight interference fit.

Cheer's Kitto, I will give the standard bolt a go. At first I didn't think it would fit on at all, although I just measured with digital callipers. I sent it back to Ross and he checked it with a proper inside mic and the measurements were apparently all good and within spec, so I will give it another crack tomorrow with the standard bolt.

It is a pretty chunky bolt, should be OK I think.

The balancer should just sit on the tip of the crank before it stops. Then you start winding the bold in.

Make sure you put never seize on the crank.

Thanks Kitto, you were right, it went on pretty easy.

Not happy with Ross, I just got the balancer back from them and they have dropped it, putting a huge dent in it (picture attached). The box they sent it back in was fine so it was obvious they dropped it before sending it back. :rant: I put it on anyway, hopefully it will be alright.

Far out, thats bad! Id be looking at them getting it fixed, especially for what they cost.

Yes I should complain given the cost, but to be honest I'm sick of dealing with them and waiting to actually install it, so I'm just going to leave it. It shouldn't have any effect on it balance or function, or at least I hope!

Dude if your 100% sure that the damage was NOT there when you sent it dont ask ROSS.... DEMAND a brand new one... Its called a HARMONIC BALANCER for a reason... Not a banged up lump of steel and rubber to drive belts!!! The fact they sent it back like that is INEXCUSEABLE imo..

PS: Make sure you torque the bolt correctly? Not the old "Impact/Rattle Gun" She'll be right method....Its the Number 1 cause of oil pump failures on RB's......Crappy chinese (were many branded items now come from), old clapped out balancers are up there aswell.

      Need AC Compressor for R32

      By Zabuza · Posted

      Ok glad you clarified on the frenchy’s options , I was worried about if my oem hoses would fit the new compressor or not if I just bought the bracket/compressor kit ,  didn’t realize they also sold a larger full conversion kit. Hmm may just go oem in that case then to make it easy only because I plan to sell this car to upgrade to a 32 GTR or 34 GTT.

      Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?
