GS1000 Turbo, attempt no 2

Recommended Posts

Have been busy again.. about time too ;)

 

Half of the crank is done now, damn it takes a lot of time, it's not real hard, just time consuming.

 

Now I need the straight cut gears, before I can finish the crank, but other things coming up, so I'm afraid it's going to take a while again.

But there's a little bit of progress.

It took a while.... But, today the straight cut gear for the crank came in, so I finally can build my crankshaft :)

Finally, I've finished the crankshaft... 

 

All to 0.04mm acurate, new main bearings, new big ends (the last 4 in the world I think ;) ) 493 rods, side clearence on the rods a wee bit more as the minimum clearence according to the manual, straight cut gear.

Don't think i've heard of anyone pressing up their own crank before - good job. Bit of weld I spy on that S/C gear? Is the rest fully welded?

Are you going to bother with balancing - shame not to!

Yeah, bit of a weld on the gear, I see that on all the welded cranks, all is welded..

 

Not sure regarding balancing, I've been told these sort of cranks can't be balanced like it is now

Must be possible - these cranks in ProStock motors have 14k redline - no way they aren't balanced ........... 1850cc as well!

I'll see if I can find someone, the con-rods can be "locked" in position, so hopefully it can be done..

I was told they can only be Statically Balanced.........

My understanding was that all the parts were weight matched before assembly O.o

The V&H Pro Stock rental motors only do 4 passes before a tear down.............:o

It was only a friendly question! The OP has pressed up a nice crank to exacting tolerances - its straight and all the parts may be weight matched - but what about the weld dotted around the pins? Only takes a few grams to end up with a vibe monster. V&H dynamically balance their cranks - https://products.vanceandhines.com/store/suzuki/33-9113/

1460 On most prepped Drag cranks i've seen Weld on pins is exact opposite on pins and of equal length, so more of worked out maths to be same weight on opposite throws to even out or eliminate vibration.
