Have done a bit of research and found many older postings on UN1 gearboxes and NG3 gearboxes.
Have worked out that UN1 gearboxes appearstronger and better suited to higher load/torque situations than NG3 but also appear but be rarer than the proverbial hens tooth.
Investigations else where have come up with other UN numbers such as UN5 in a renault master van, can anyone entitlighten me as to whether the UN1 box has a newer stronger replacement and what vehicles if any it can be found in.
Also is there any web source for gear ratios etc that anyone knows of. :adrink:
I currently have an old 4 speed UN1 attached to a rover V8, I did not do the join but am curious to know why the box needed to be turned upside down and presumably the diff switched over. Any details would be helpful.
