MQ 5pd conversion problem

[Brendan-s]

Hey everyone, have got a little bit of a problem I was hoping someone might be able to shed some light on.

Basically, when my 4spd in my MQ diesel Patrol gave up the ghost I put a 5spd from a later-model MK petrol Patrol in. It was a fairly easy swap, as far as custom stuff goes, just had to get some custom shafts made up as well as custom gearbox mounts. Everything's bolted back together fine, the rear shaft is in, I can drive the thing around... almost...

The problem is that when we put the box in, I left the pushrod that goes from the slave cylinder to the clutch seperator fork out. It was a bugger to get back in so I undid the bracket which the slave cylinder bolts to the bellhousing to, slid the pushrod in and did the bracket back up. Now, the pushrod is on a nasty angle (probably like 30° to straight horizontal) and it seems the clutch won't engage properly.

Does the pushrod have to sit dead-straight on between the fork and the cylinder? If it does, why when I used the original bellhousing, original clutch fork and original slave cyl has this changed? Please help, any ideas are welcomed!

A pic or two would work wonders here.

But anyway, on a totally different gearbox swap I've done, I had to mount the slave cylinder on a flat plate that utilised the standard bolt holes, then had its own new bolt holes for the slave cyl, repositioning it lower down on the box and inline with the clutch actuating mechanism.

thanks rock... i rang nissan before reading here on a tip from my boss who confirmed it. could someone possibly post a pic of a later model one so I can see how it sits? also casn someone explain why I should need a different slave cyl when it's all original stuff down to the bellhousing?
