SPACER 2G8093 - Caterpillar

Visual Checks
1. Check the oil level in the transmission and differential.2. Check all oil lines, hoses and connections for leaks or damage. Look for oil on the ground under the machine.3. Move the control lever to the REVERSE position and all FORWARD positions. The detents must be felt in all positions.4. Check the transmission control linkage for damage.5. Let the oil out of the housing for the transmission oil filter. Remove the check the filter element for foreign material. Check the magnetic strainer in the case of the transfer gears.a. Aluminum particles give the indication of torque converter failure.b. Bronze particles give the indication of worn clutches in transmission.c. Rubber particles give the indication of rubber seal or hose failure.d. Shiny steel particles give the indication of pump failure.e. Iron or steel chips give the indication of broken components in transmission, differential or transfer gears.If you find bronze, rubber, aluminum, iron or steel particles, all components of the hydraulic system must be washed clean. Do not use parts with damage. Use new parts.Checks During Operation
With the engine running, move the selection lever to all speed positions. The detents must be felt in all positions.Operate the machine in each direction and in all speeds. Make note of all noises that are not normal and find their sources. If the operation is not correct, make reference to the CHECK LIST DURING OPERATION for "problems" and "probable causes."Check List During Operation
PROBLEM: Transmission gets hot. PROBABLE CAUSE:1. Bad temperature gauge.2. Low oil level.3. High oil level.4. Core of oil cooler not completely open.5. Low oil flow as a result of pump wear.6. Magnetic screen not completely open.7. Long periods of operation with converter at or near stall speed.8. On machines with retarders, to much use of retarder. PROBLEM: Transmission lever does not make a shift. PROBABLE CAUSE:1. Adjustment of control linkage not correct.2. Control linkage damaged.3. Clutch not releasing. PROBLEM: Slow shifting. PROBABLE CAUSE:1. Low oil pressure.2. Adjustment of control linkage not correct.3. Control group for shift pressure not operating correctly.4. Air leaks on inlet side of pump. PROBLEM: Clutches engage very suddenly (rough shifting). PROBABLE CAUSE:1. Adjustment of control linkage not correct.2. Primary setting of the relief valve not correct.3. Load piston not closing.4. Valve springs that are weak or have damage. PROBLEM: Transmission does not operate in any speed or does not engage (slips) in all speeds. PROBABLE CAUSE:1. Low oil pressure caused by: a. Low oil level.b. Control linkage loose or adjustment not correct.c. Failure of the oil pump or oil pump drive.d. Air leaks on inlet side of pump.e. Leakage inside transmission.f. Adjustment of the modulation relief valve not correct, or valve does not close.g. Spool for flow control valve does not close.2. Mechanical failure in transmission.3. Automatic selection group not operating.4. Failure in torque converter.5. Failure of the differential or the final drives. PROBLEM: Machine moves in NEUTRAL. PROBABLE CAUSE:1. Adjustment of control linkage not correct.2. No. 4 clutch not engaged (slips) because of: a. Low oil
