REPLACEMENT OF TRANSMISSION OIL PUMP
The paver is equipped with an oil pump on front end of transmission. (Item 65, Figure 51)This pump provides positive
lubrication circulation to gears and bearing in the main transmission.
If it should be necessary to replace pump, it is important that it be properly mounted.
Failure to follow this assembly procedure can result in premature failure of the pump.
METHOD:
1. Check condition of upper shaft bearings in transmission. A slight lateral movement of shaft should be possible if
bearings and shah are in acceptable operating condition.
2. Inspect pump coupling for wear and make sure it will slide freely on pump shaft. Also, inspect driving slot for
coupling in transmission shaft. Replace parts if worn.
3. Assemble pump to transmission and only finger tighten bolts. Fill pump with the recommended transmission
lubricant.
4. Attach lube lines to pump. Do not completely tighten lines so that the pump will be free to align itself to the
transmission while rotating.
5. Start engine and engage clutch. While pump is operating , tighten mounting capscrews evenly and
progressively.
6. Tighten lube lines securely.
7.
TRANSMISSION OIL LINE FILTER
A fine mesh filter screen is used ahead of the oil supply line of the transmission pump to keep the foreign particles
from damaging the pump. This filter is a cartridge type unit which is screwed into the transmission housing. The oil pump
suction line fitting is then screwed into the center of the filter cartridge. (Item 86, Figure 51)
If an oil pump in apparent good condition fails to maintain a good flow of oil through the sight glass, a plugged filter
screen may be responsible. If this is suspected, back-flush the strainer and transmission case as follows:
1. Disconnect the suction line to the pump and attach a hose and funnel so that flushing solution can be poured into
the line.
2. Drain the transmission oil, then re-install the drain plug.
3. Pour a quantity of Texaco Rando AA flushing solution into the gear case through the pump suction line to
back-flush the filter screen. Fill the case to a point above the normal oil level (on dipstick) and allow several hours for the
solution to dissolve the oil residue.
