Early (2005 and older) vs Late (2006+) Crankshafts

[zx809]

i also have a 2012 rxpx and im going to be putting the crank from a 04 in it what do i have to change?? everything will be 2012 except the crank??

[nmpeter]

well here we are again....I have a perhaps 05 or 06 4tec coming in this weekend to have this problem solved

"somehow" "somebody" appears to have mixed up the parts from two different motors during a rebuild...or who know what

all signs point to the timing being wtfo.

i have a slightly different problem. Is it ill advised to try to pull the pto with the engine still in the ski..or is it a suicide mission.

blunt honesty please. I'd prefer not to pull the engine. Again, I get sucked into these things because the guy has according to him about 7k into this ski and he believes I can save him from his wife for a fair price. and besides, I love a cheeky problem and this one, correct me if I'm wrong is in the top ten mistakes for parts swapping.

my bet is later model crank, early PTO and wheel

[4tec Hoarder]

Pull the engine, it takes less than an hour, and will save you a lot of swearing.

[nmpeter]

this engine was installed by another guy, have no idea what I'm going to find as far as the wiring. I suspect its a cut and splice job too.

but I'll take your opinion under advisement after I have the ski in hand.

I dinged my elbow badly last season and I'm maybe not quite ready to wrestle the engine

appreciate the very early morning response however...

[nmpeter]

well I pulled the engine out inbetween a bunch of startup services this week and found some curious bits

the folks that put this together totally screwed getting the encoder wheel on correctly...or did they. It had been incorrectly installed

Couldn't find my crank locking tool, so I should have my new one by tomorrow and a set of new flywheel bolts

the engine coughed now and then, but all the particulars were in order I assumed since these guys didn't use new head or flywheel bolts they could have easily done this.



the block for sure is a 2004, but I'll have to take a good look at everything once I get the crank locked up.

This engine was coming apart anyway, the flywheel bolts had been reused.

the encoder wheel has no part number on it so 10+ years later who knows what's really going on.

I'd like to get this right the first time obviously so if you got something say something!

[nmpeter]

with the wheel in the assumed correct position the motor coughed a few times and fired right up!.

unfortunately, the head gasket is leaking oil.

that's right folks, you can reuse a head gasket by spraying it with a can of high tack and the bolts?..well the look okay..what could happen?
I can imagine what the flow will be when the engine is allowed to come up to full temp

This ski is the moneypit of 2018 and it's not even july 4th yet

it's got all new mats and upholstery, so much money spent on this one it's near humorous

[nitrousballa45]

can you do the same thing with a 300 crank in an 04 motor would be a 300 motor incognito pull pin rotate counter clock wise 2 bolt holes plus a half tooth.

Im going to revive this for some additional insight. I seem to be reading that most people here are swapping either 2006 and up crankshafts in to the earlier engines or vice a versa. In my case I have a 2004 or RXP that threw a rod on the memorial day weekend. I have found a great deal on an early 2006 215 engine (complete) i have had zero luck at finding an 04-05 engine at affordable cost. So basically what I will have is one complete 2004 engine (with hole in the side of block) and all of my complete working 2004 rxp electronics (no codes present before failure, all sensors etc are good). I will also have a complete 2006 engine manufactured 02/06. So... differences I take what I need to do is rotate the wheel 120 degrees clockwise on the 06 engine and use the PTO cover with 06 sensor and plug it into my 04 harness and good to go aside from a 7-9 degree static timing difference which the ecu will compensate for? What about all of the other sensors etc? I just want to compile a checklist of what all I need to do before I can drop this engine in.

If you use the 06 crankshaft and the 06 PTO cover, you shouldn't have to rotate the wheel.

Just wanted to update this thread. The 04 Crank Positively works in an 06 w/ 06 Electronics. Just remove pin from Crank & rotate Reluctor wheel counter clockwise 2 Bolt holes. I would assume the same could be said for using an 06 Crank in an 04 Engine, just rotate Reluctor/Flywheel 2 Bolt holes Clockwise. The plugs for both the stator & CKP Sensor are the same, so its plug and play.

So to place a 2005 215 motor in a 2007 rxp ski I just need to pull the timing cover, move the reluctor wheel two bolt holes counter clockwise? Do I need to use new bolts or can I reuse the old ones?

[nmpeter]

you want to absolutely replace the bolts, they are inexpensive. Consider them insurance against having to go in there again for a good long time. Be careful with the timing wheel, the large magnet can throw you off. double check before you button it up. make sure the gasket surface are clean clean clean as a messy PTO cover seal is just fuggin ugly. I'd mark the position with yellow paint before disassembly so you get the correct offset on reassembly. Do the next guy a small favor and mark an area on the interior and exterior of the pto with the year of the engine.

Keep in mind. I am typically the next guy

Why don't you just use the timing cover that came with the 05 motor instead?

Will it work that way? If it will I will absolutely do that. I was advised by the guy I am buying the engine from that the timing cover would need to be changed. I came here for a second opinion to see what would be needed.

Here is the original post I made on Greenhulk asking if it would work. I was advised that I would have to modify the reluctor wheel.

Thanks!

Ive read through this thread probably 10 times. Im just trying to be 100% sure im getting this right. I have a 2002 GTX 155 that the motor gave up on. I bought a 2008 GTX 155 with 34 hours on it. The 08 ski was trashed so i pulled the 08 motor and dropped it in my 02. I installed the 08 longblock with the PTO cover and flywheel but swapped everything exteral from the 02 motor on to the 08. The ski fired right up and seem to run fine. Once in the water it didnt want to run above idle. So after some calls to a few places that claimed to be in the know I pulled the motor and replaced the 08 PTO, flywheel and encoder wheel with the 02 parts. Now the ski wont start.
So after reading this thread Im thinking I need to clock the 02 encoder wheel 127* clock-wise. Is this correct? If so Ill have a machinist buddy of mine move the locating pin hole 127* and then move the bolt holes 7*. I will use the PTO from the 02. I just want to make sure im doing this right. I dont want to pull the motor again!
