Within the hour you could have the rocker cover off a Perkins 1004 and a feeler gauge between rocker and valve tip. Set them cold: 0,20 mm inlet, 0,45 mm exhaust, working through firing order 1.3.4.2. This book covers the Manitou ML 632 and ML 635 through the MT 1740 SL, Série 2.
Few things are worse than a telehandler that revs hard but won't push into a pile. The shuttle transmission section covers the forward and backward line of force, clutch pressure checks and troubleshooting. You can test the transmission before you split anything.
The complete Perkins TPD 1350 workshop manual is bound in. Axles, brakes, boom, cylinders, hydraulic pressures, diagrams and the stability alarm are all covered. Work through it and the machine will lift and drive again.
