IMPORTANT:
Avoid Damage! Use liberal amounts of transmission oil to lubricate components as they are assembled. DO NOT use grease or other heavy lubricants unless they are called for.
[1] – Lubricate PTO clutch assembly bearings, seals, and bearing bores.
[2] – Install clutch assembly through top of gear case.
[3] – Insert front of assembly fully into gear case bore (A).
[4] –
IMPORTANT:
Make sure tang rests on gear case housing to avoid interference damage when installing rockshaft.
Rotate installed clutch assembly so that PTO brake reaction tang (B) rests on gear case housing stop (C).
[5] – Hold PTO shift gear and collar in position as temporary support tool (D) is removed.
[6] –
โNOTE:
Ensure that the M-B-R shift fork is engaged in the shift collar as the pinion gear shaft assembly is installed.
Index shift gear to PTO clutch drive gear and install pinion gear shaft assembly (E) and idler gear assembly (F).
[7] – Apply form-in-place gasket compound to gear case rear cover sealing surface (G).
[8] – Install rear cover and nine M8 x 30 cap screws. Tighten in a cross pattern to specification.
[9] – Install new O-rings (H) to grooves in gear case front cover.
[10] – Lubricate bearing surface (I) of PTO through shaft.
[11] –
โNOTE:
Rotate the PTO through shaft while installing it to the gear case in order to index shaft splines to the internal PTO drive gear and the rear pump coupling.
Install shaft through front of gear case, exercising care to not damage PTO clutch pilot bushing.
[12] – Index hydrostatic drive unit input and motor shafts to gear case couplings. Install unit to gear case and secure with five cap screws.
[13] – Apply form-in-place gasket compound to rockshaft bottom sealing surface.
[14] – Install rock shaft housing to gear case with six M10 x 50 cap screws (J) and two M10 x 70 cap screws (K). Tighten in a cross pattern to specification.
[15] – Install hydraulic pipe from hydraulic pump to rockshaft and tighten fittings.
[16] – Fill gear case with specified amount and type of oil.
[17] – Install suction pipe and hose from suction filter fitting to hydraulic pump. (See Remove and Install Oil Suction Screen in Section 70, Group 05.)
[18] – Install drain plug.
