Drivetrain Alignment.

[KatoKid]

Some questions out of curiosity but also to help with my build......

 

Its pretty common knowledge that the engine and trans in 240's and 260's are offset to the drivers side but Ive never seen an explanation for it. Does anyone know why? I'm guessing its for clearance for carbs/airbox or even something to do with providing exhaust system clearance for the LH drive cars?

 

I measured engine/trans position in my car before I pulled it and crankshaft nose is 20mm closer to the drivers side and the trans output was 5mm closer to the drivers side so this raises a few questions and bear in mind I didn't check the diff location before I pulled it:

 

1/ Above measurements would indicate the engine /trans is installed on an angle IE. not parallel with the centreline. If this is so, logic would say that the diff is also slightly angled to maintain the correct tailshaft alignment?

 

2/ Has anyone checked if the diff pinion is in the centre of the car or if the diff is parallel with the centreline or angled ?

 

3/ Have I measured my car incorrectly and the whole drivetrain including diff is actually parallel with the car centreline, just offset to the drivers side?

 

Reason I ask all this is that I'm contemplating using a non Nissan/Datsun diff and CV shafts and want to understand what to look out for when it comes to positioning the new diff so I don't have any NVH issues.

 

Cheers.

equal halfshaft length that can preferably maintain the same angularity through bump to droop. ie 1 short & one long the angularity diferentiation is greater for the shorter shaft.

but with and around the limitations of its enclosure, ie the body shell.

less angle is better, no angle is best.

soft mount anything that vibrates if possible, also if noisy in operation, sound deaden or shield it with a softer panel/material than body

can answer the q's above but lunch is up.......
