If it is determined that an overhaul is necessary, then inspect the entire engine for any evidence of external leaks, or defective parts, that must also be corrected before the tractor is assembled and returned to the customer. ENGINE The model Z-134 engine is a four cylinder, spark ignition, overhead valve type engine, using wet sleeves with a bore of 3-5/16 in. and a stroke of 3-7/8 in. The engine is manufactured with two compression ratios: 6.6 to 1 (regular) or 8.10to 1 (hi-altitude). Piston displacement is cubic inches for both compression ratios. The 6.6 to 1 compression ratio engine in the TO 35 Tractor developed corrected belt horsepower. Maximum engine torque occurs at an engine speed of approximately 1200 RPM.

8 INDUSTRIAL TRACTORS MASSEY-FERGUSON TROUBLE-SHOOTING Problem - Clutch won't release Possible Cause a. Oil or grease on friction disc b. Improper pedal adjustment c. Damaged pressure plate or clutch cover d. Friction disc hub binding on splined drive pinion shaft. e. Distorted friction disc f. Broken facings or friction disc g. Dirt or foreign matter in the clutch Correction a. Install new friction disc b. Adjust clutch pedal free travel and linkage c. Replace defective part d. Clean up splines and smear with small quantity of "lubriplate (Grade 70)" e. Install new friction disc f. Install new friction disc g. Remove clutch from flywheel and clean with dry rag. See that all working parts are free Problem - Clutch slip Possible Cause a. Oil or grease on friction disc facings b. Weak coil or Belleville spring. If excessive slip is allowed to occur, the heat generated will soften the springs and aggravate the trouble c. Binding of clutch pedal mechanism preventing its full return to stop d. Improper pedal adj ustment preventing full engagement e. Clutch facing worn Correction a. Install new friction disc b. Install a new set of thrust springs (primary clutch), or a new Belleville spring (secondary clutch) c. Free bearings. (NOTE: The clutch shaft bearings in the transmission case are selflubricating. Oil or grease should not be applied. ) d. Correct pedal adjustment e. Install new friction disc Problem - Clutch grabbing Possible Cause a. Oil on friction disc b. Binding of clutch pedal mechanism c. Worn out friction disc facings Correction a. Install new friction disc b. Free bearings. (NOTE: The cll1teh s~t bearings in the transmission case are selflubricating. Oil or grease should not be applied. ) c. Install new friction disc 16

The procedures will be the same unless otherwise specified. For overhaul procedures of the transmission, refer to the appropriate unit Divider Tab (i. e.: Manual Shuttle, 6 Speed Trans.) under this major group. (These transmissions may be either a "Single-clutch type" or "dual clutch type". Check which type is installed in the tractor being serviced and refer to the appropriate Divider Tab. ) Printed in U.S.A. 1

Tractors after the serial nos. listed above will have the Response Control located on the right side of the center housing as shown in Fig. 1. The lift links can be raised into transport position with either the Draft Control Lever or the Position Control Lever. To operate the Hydraulic system in Position Control, the Draft Control Lever must be all the way to the rear of the quadrant. The lower links can then be positioned by the Position Control Lever. When the Position Control Lever is moved toward the rear of the quadrant, the lower links will raise. When moved toward the forward side of the quadrant, the lower links will lower in proportion to the position of the lever. This lever is used for attaching and operating equipment that is not draft controlled. To operate the system in Draft Control, the Position Control Lever must be placed in transport position (to the rear of the quadrant against the stop). The Draft Control Lever, which is on the outer quadrant, is provided with an adjustable locater. This Printed in U.S.A. 1
