Few questions from first few outings in 1989 2.5Di

[jaycey001]

Hi

I brought a 1989 Transit with the 2.5Di engine a month or so ago and have taken it on a few shake down runs before the southern Spain trip in July.
As expected there were a few electrical niggles and bits that needed sorted but apart from them there are a few other bits id like some advice on.

Firstly, It likes to jump out of 3rd gear when De-accelerating all the other gears are fine, its just 3rd which i think is a bit unusual considering its normally 1st or 5th that has the problems. it has the type9 5 speed box, is there a locking pin that could be worn or is it likely more terminal?

Secondly, is it normal to be having to drop to 2nd gear on long inclines? I am used to my 300tdi defender which isnt fast, but the 2.5 does seem to struggle on hills and thats in Suffolk so am not sure how well it will do when faced with anything substantial!

Despite all that, the engine is great and runs perfect and i would be reluctant to change it due to its low miles (37k) its just the gearbox I would like to sort if possible.

Cheers

Not sure about gearbox as morlst have mt75 s which are bulletproof....
If your fuel pump had a sort of 'castle' or tower but in top with a metal cap pull the bugger off undo the nut below with a 13mm socket un some mole grips and stuck a 4mm hex key into shaft and wind it in clockwise about 2 or 3 full turns lock nut up again and go for a wee drive...
TOTALLY transforms all di' s but only those blessed with manual pump..if has more than 3 wires visible from it its got an ecu so can not be tweaked...

Thanks - mine has the Lucas pump do you know if that can be tweaked the same way as the bosh units? I definitely dont have an ECU though

Not an Epic, just the lucas CAV....

The type 9 is generally regarded as a weak link when fitted behind a Di especially in a Lwb.
Make sure you have full recovery if you go overseas as they can fail with no warning

Look for torque adjuster in the top of pump...metal cover riund and prob ali aplrox size of 5p or tad bigger

Wrong pump Rob, this is the early Lucas CAV pump.

I've lifted this from another thread, I've never tried it and don't know if it's correct but here ya go.

I think if I remember rightly remove the blue cap and then take the screws out behind it slide the plate off the splinted shaft and use the plate to turn the shaft not sure Whitch way to turn it long time since have done one .
