33 Box On Neo Engine. Loud Grinding Noise.

[wildeagle44]

Hi.

Finished doing a neo motor swap into my 33. Only thing i changed was the block, still using all the 33 accessories, gearbox, clutch, slaves etc

Let the car idle for 20min to bleed coolant and went to take for test drive. After reversing 3m down driveway there was a very loud grinding noise. Clutch was engaged at the time.

Turned car off, checked everything and tried again. No noise. Go drive 50m and noise comes back. Again turn off, back on no noise. 50m again the noise came back. Put in neutral noise was there clutch in or out.

First thought was throwout bearing. Pulled the box, seemed alright. Will have a better look tomorrow.

Am i on the right track? Searching seems to bring up similiar symptoms for throwout bearing. But this is seriously loud. Like angle grinder loud.

Or could there be somthing up eith the carrier since i changed motor?

Any help is appreciated. Thanks

Was the new motor from an auto? You need to change the auto spigot in the flywheel for a manual one. Don't know if that would cause your symptoms though and not sure if you could even have got the box in now I think about it...excuse my rambling I'm tired...

Yeah you can put a manual box in with an auto spigot. The auto box input shaft diameter is quite a bit larger than the manual one.
