MATING THE FLYWHEEL HOUSING AND BELLHOUSING
It is possible to take the flywheel housing from the 19J engine and fit this in place of the housing on the back of the 300Tdi. But we choose to adapt the 300Tdi housing so that its lower stiffening brackets can be retained. These brackets on each side connect the engine block to the bottom of the flywheel housing and are beneficial for the more powerful and torquey engine-gearbox combination.
Luckily, I had a spare 300Tdi flywheel housing and LT77 bellhousing, making it easier to illustrate the process for this feature. This also allows trial fitting to the back of the engine on the floor, and to the gearbox in the Land Rover.
14 So we apply this same work to the real flywheel housing on the back of the engine, so the bellhousing will fit perfectly in place here, too.
13 With the extra stud and locating dowel removed, the spare flywheel housing and bellhousing now mate together perfectly on the bench.
7 This spare 300Tdi flywheel housing is identical to the one that came with the replacement engine. The lower stiffening mounting points can be clearly seen.
10 The removed stud will be used at the bottom of the flywheel housing, so the locked together M10 nuts are left in place for the time being.
9 One of the studs to the right of the flywheel housing is removed by locking two M10 nuts together on the stud, to turn it with a 17 mm spanner.
8 A spare LT77 gearbox bell-housing will allow a trial fit to the back of the replacement engine, which proves valuable in highlighting a potential problem.
11 One of the locating dowels on the flywheel housing also needs to be removed. The location is detailed in the instructions from Steve Parkers Ltd.
12 The dowel is fairly easily removed by gripping it with engineer’s pliers and rotating it back and forth, with upwards pressure at the same time.
