Crank Shaft Measurments

[luke.t.]

Hey guys

just wondering if anyone has a crankshaft out of a 4k that they can measure for me (with precision equipment) the standard size of the crankshaft where the rear main seal is.

I stupidly had the gearbox out and didnt check it when i last did the rear main and its leaking again. It had a groove from the old rear main so i tried to just reposition the seal.

That didnt work cos its done approx 1000kms with no issues but now is leaking like a teabag. I would do it myself but don't have the correct tools to get precise measurements.

I will be speedy sleeving the crank if your wondering why i need measurments.

or maybe someone knows the correct sized sleeve to get?

cheers for the help

not entirely sure what you are asking, but if you grab a 4k engine manual wont that give you the oem tolerances of the shaft?

I'm after the size of the rear part of the crankshaft. When you install a rear main seal the surface of the crank that sits on. so the diameter of the crank where the rear main seal sits lol....

The old seal has worn a groove and i need to sleeve it so it wont leak anymore.

just make the seal stick out 1mm so it sits on a new surface.

Speedy sleeve FTW. The rear main I have sitting here is 92mm OD, 70mm ID 8.5mm Wide.
