gears don't engage
A friend at work has a spartan with a sierra box in it. He is just trying to put it back in after a rebuild, but when its in it won't go into
gear but on the bench its fine. Any ideas?
More details - It will go into gear when engine not running but not when running.

Does it try to go in , but make horrible grinding noises? Does the clutch fully disengage? If bot sure, point the car down an open empty drive, stick
it in 2nd, put the clutch down and try to start it. If it jumps forwards the clutch needs looking at it. If it doesn't jump, then
something's up with the box.

Clutch not clearing! If he carries on trying he will end up damaging the box, another possibility is the spigot bearing in the rear of the crank
picking up on the first motion shaft.

slector fork dowel sheared..?
A friend of mine recently lost almost all of his gears in his type9 box(westfield....) after a trackday..
all he can get is 5th and reverse..
We've stripped the engine and box out of the car, and took the top off the gearbox, to discover the hardened dowel that locates the selector
fork to the top rail had sheared above and below the rail, allowing the selector fork to slide along the rail freely.. previously he had spoken to BGH
geartec and they over the phone diagnosed the problem, and later it proved to be 100% accuarte..
If your problem turns out to be this, semi-easy fix, replace with a 8.8 or 10.9 short bolt (4-5mm dia) with head so that it cant completeley drop
though., better still skim the threads down a bit so they act like teeth, and also allows you to unscrew/remove it later after gently tapping it in
with a hammer..
BGH recomendation was to replace the std dowel (rolled hollow dowel) and put a 2mm stainless pin through the center of it to give extra strenghth..
RobinHood 2B 2.0i pinto, Keihin 38mm Carbs, lightened flywheel, O'Mori remote filter kit, 10 row oil cooler. Modified head, 10.2cr, special
valves FR22 cam, 4- 1 header.
