Crank Seal Guard Install Instructions

This guide provides step-by-step instructions for correctly installing the Crank Seal Guard. Read all instructions thoroughly before beginning installation.

Items included in this Kit: 

  • 1x MaLo Industries Crank Seal Guard
  • 2x M8 zinc plated bolts
  • 2x Zinc plated washers
  • 1x Loctite medium strength 0.5ml
  • (Optional: 2x Aluminum bolts)

Tools needed for the install:

  • Torque wrench
  • E10 inverted Torx socket
  • E12 inverted Torx socket
  • T60 Torx socket
  • 10mm socket
  • Long wobble bar extension
  • Breaker bar 5mm
  • hex socket (4mm hex socket for optional aluminum bolts)

Install Instructions:

  1. Secure the vehicle (jack stands, ramps, lift) 
  2. Remove the cooling fan and splash guard. 
  3. Loosen the six E10 crank pulley bolts. Do not remove them at this stage. 
  4. Using a breaker bar and T60 Torx socket, remove the serpentine belt by rotating the tensioner clockwise. 
  5. Create a reference mark on the crank pulley and place a matching reference mark on the main crank bolt so the crank pulley can be reinstalled in the same orientation. 
  6. Remove the six E10 Torx bolts and remove the crank pulley. 
  7. Using an E12 Torx socket and a long wobble extension, remove the two aluminum bolts. There's one on each side of the crank seal.
  8. Inspect the engine block face where the plate will seat. Remove any burrs, high spots, or debris that may interfere with a flush fit.                                                    ⚠️ Clearance Advisory The clearance between the Crank Seal Guard and crank pulley can be minimal. Ensure no interference before proceeding. 
  9. Apply medium strength Loctite to the bolts and line up the plate over the crank seal and install the two bolts along with the washers finger tight. Adjust the crank seal plate so that there is an even amount of space between the crank seal plate and the crank hub. Ensure a flush fit with your engine block. 
  10. Starting with the left bolt (passenger side on a LHD car), torque the bolt to 15 ft-lbs. (20 Nm) then the right one. (For aluminum bolts use 6 ft-lbs. ( 8.5 Nm // 75 in-lbs.)) Make sure after tightening, that the plate did not bow or deform . It has to sit flush or it may rub against the pulley. 
  11. Reinstall the crank pulley using your reference points and torque the bolts to 35 Nm in a star pattern. 
  12. Reinstall serpentine belt and cooling fan.

Always verify with the latest BMW factory documentation for your specific vehicle model.
