TM 5-3805-262-343-7. TRANSMISSION MAINTENANCE a. PressureTests.This task covers testing of transmission. Testing consists ofperforming main pressure check, cooling circuit check, and oil flow out of transmis-sion check. Do these tests whenever you suspect problems in the transmission.TOOLS: No. 1 Common Organizational Maintenance Tool KitFixed open end wrench setPressure gage, zero to 250 psiFlowmeter (FSCM 45225 PN CAS-10280)Flowmeter fitting kit (FSCM 45225 PN CAS-10106)MATERIALS/PARTS: Lubricating oil (Appendix C, item 15)PERSONNEL REQUIRED: Two Construction Equipment Mechanics MOS 62BREFERENCES: TM 5-3805-262-10TM 5-3805-262-20PRELIMINARY PROCEDURE:5-3805-262-10) .MAIN PRESSURE CHECK (SHEET 1NOTEEngine right side panels removed (refer to TMOF 3)(1)(2)(3)(4)(5)Check transmission oil level (refer to TM 5-3805-262-10). Add oil asnecessary.Perform engine stall tests (page 3-19) to be sure problem is in transmis-sion.Check adjustment of control valve linkage (refer to TM 5-3805-262-20).Adjust control valve linkage as necessary.Remove clutch pressure switch from transmission control valve (refer toTM 5-3805-262-20).Connect pressure gagehose to transmissioncontrol valve port fromwhich clutch pressureswitch was removed.
