Application: E9, E7 & E6

The 37720 Roller Lifter & Tappet Holding Kit is a specialized engine service tool engineered to securely retain roller lifters and tappets during engine maintenance, overhaul, or component replacement on Mack E‑series diesel engines. Proper retention is critical when performing tasks such as camshaft removal, rocker arm service, or top‑end inspection. Without a dedicated holding system, lifters can drop into their bores, become damaged, or be reinstalled incorrectly—leading to costly downtime and rework.

This kit uses purpose‑built rods and retainers that hold lifters and tappets safely above the camshaft, allowing technicians to remove and install camshafts, pushrods, and rocker assemblies with confidence. Instead of relying on improvised methods like magnets or tape, 37720 provides a stable, organized, and professional solution throughout disassembly and reassembly.

Ideal for professional diesel repair shops, fleet maintenance operations, and engine rebuild facilities, this kit improves workflow efficiency, prevents component loss or damage, and supports accurate reassembly to manufacturer specifications.

Kit includes:

  1. 37720-13A Magnet (16)
  2. 37720-14B Instruction Sheet (1)
  3. 37720-5A Top Rod (16)
  4. 37720-6A Grommet Kit (1)
  5. 37720-7A 30" Storage Pouch (1)
  6. 42425-3 Magnet Cap (16)
  7. 42425-4 Bottom Rod (16)
