Type 9
Bought a type 9 box from a 1.8TD sierra (diesel of course!) that lots of people on the web/forums have said that it will have a 4.1 (or something
equally horrible) as a first gear ratio. BUT, it has a 1st gear ratio of 3.65 like 4 cylinder petrols yet has a long input shaft like a 6-cyliner
petrol.....
http://www.type9gearbox.co.uk/type-9-production.html
Will this box be a stronger build as (it is from a deisel) than the petrol engines or is it likely to be the same ?
Is there anyway I can see (if I remove the top plate) to know if it is stronger (bearing/synchomesh etc) ?
Thanks in advance
Andy

The heavy duty box has a layshaft bearing stub bolted into the main case with 3 bolts. in the end of the layshaft cluster is a roller bearing pressed
in. The normal box just has the end of the layshaft spindle visible in the main casing, about 19mm diameter (remove the bell housing to see the end)
and the layshaft cluster runs on this shaft with 21 needle rollers.
Other than variations in the 5th gear selector mechanism dependant on age and gear ratio's, the rest of the bearings/syncro's etc are
identical between the two.

The 4 pot box has a short input shaft with 18 teeth and a short cover (3.65 first)
The 2.8 box has a long input shaft with 19 teeth and a long cover (3.36 first)
The 2.3 box has a long input shaft with 18 teeth and a long cover (3.65 first)
The diesel box has a long input shaft and 18 teeth and a short cover (3.91 first)

Don't confuse the number of teeth on the gear (as listed above) with the number of splines on the input shaft. That is 23 for ALL type 9
variants.
Also remember that over the years many boxes have been stripped and rebuilt using parts from other boxes.
I have seen a diesel box fitted with a long cover to potentially confuse the buyer into thinking they were getting a more valuable V6 box.
