description

The 214-7187 is complete camshaft assembly for original 3126 engine, integrated with drive gear and thrust plate. It drives both valve tappets and mechanical fuel pump. This classic engine is fitted on older earthmoving machines and highway trucks under heavy vibration and variable load. Lobe pitting, spalling or journal scoring leads to poor acceleration, rough idle, uneven fuel delivery and smoke. Severe damage causes valve-to-piston contact. Its cam profile and flange dimension differ from 216-7921 for 3126B, direct swap is not allowed.

Product Advantages

1. OEM timing profile for original 3126, well-matched valve and mechanical pump delivery for stable low-speed response
2. One-piece forging with integrated flange, stable concentricity and good fatigue resistance under cyclic loads
3. Thick hardened lobe surface stands frequent impact of mechanical injection pump
4. Gear included as a kit, avoids timing error from separate gear sourcing

FAQ 

1. Can 214-7187 interchange with 216-7921?
No. 214-7187 is for original 3126 while 216-7921 is for 3126B. Lift, flange and fuel calibration differ.

2. Does it fit 3116 engine?
No. Bore, stroke and cam profile are different, non-interchangeable.

3. Can the camshaft stay in service with minor scattered pitting?
Mechanical pump carries heavy impact. Pitting spreads fast and replacement is recommended.

4. Can the included gear be reused on an old camshaft?
Not recommended. Gear and cam are matched; separate reuse leads to uneven tooth wear and timing shift.
