Getting a Manitou angle gear box back together with the right shim stack and backlash is what the 28 pages of repair manual 647058EN are for, covering five variants across the MLT and MT S.B-E2 telehandler range. Your Manitou 15930, 15932, MLT 630 / 731 Turbo S.B-E2, MLT 634 / 731 Turbo LSU S.B-E2, MT 732 / 932 S.B-E2 repair manual PDF takes the main housing, input shaft and output shaft through full disassembly and reassembly, with an exploded view and torque tables. Shim pack calculations for both shafts lead into the dial gauge backlash check and sealant notes. Set bevel gear backlash at 0.12 to 0.18 mm, and seat each oil seal 1.5 mm below the housing face. Guess the shims and you tear it down twice. Gear identification numbers help you order the right bevel pair first time, and the bookmarked, text-searchable PDF finds any figure fast.

Manitou 15930, 15932 Common Problems This Manual Covers
Manitou MLT 630 angle gear box oil level low and oil dark past change interval
Drain the angle gear box and refill with 2.5 l of the recommended lubricant following page 4. Change oil after the first 50 hours, then every 800 hours max. Check the level at the oil level plug, then torque the drain, filler and level plugs to 20 - 30 Nm as listed on page 27.
Manual Section: Angle Gear Box Maintenance p. 4Angle gear box input shaft oil seal leaking oil around the input flange
Remove the input flange and replace the input shaft oil seal. Press the new seal in to 1.5mm below the housing face, as specified on page 18. Refit the flange and torque the input flange retaining bolt to 95-120 Nm. Refill with oil and check the level before running the machine.
Manual Section: Reassembly p. 18Output shaft rear oil seal weeping oil at the housing face after rebuild
Remove the output shaft rear oil seal and check the needle bearing. Refit the needle bearing into the case to a depth of 1.5mm below the housing face following page 22, then press the new output shaft rear oil seal into the case to a depth of 1.5mm below the housing face per page 23. Also confirm the output shaft oil seal sits 1.5mm below the housing face per page 21.
Manual Section: Reassembly p. 23Bevel gear set whining or grinding under load after angle gear box reassembly
Set up a dial gauge and measure bevel gear backlash following page 26. It must read 0.12 - 0.18 mm. If it falls outside that range, correct the shim thickness and measure again before you close up the housing. Shim pack calculations are on page 24.
Manual Section: Check Adjustment of the Set p. 26New bevel gears fitted with mismatched identification numbers, angle gear box running noisy
Verify both bevel gears carry the same identification number and fit them only as a matched pair, following page 15. Read the tooth marking and mounting distance data for that pair, then carry those values into the shim pack calculation on page 24. Never mix a gear from one set with a gear from another.
Manual Section: General Informations p. 15After reassembling the angle gear box, the main housing bolted joint is seeping oil
Clean both mating faces and apply sealant as covered in the Check Adjustment of the Set section starting on page 26. Torque the 12 housing bolts to 39 - 58 Nm following page 25. Refill with 2.5 l of the recommended lubricant, check the level, and watch the joint on the first run.
