IE A014TECHNICAL REPORTS ON THE SMU-46 FLEET · OCTOBER 2001
KamAZ engines: compression up, cylinders evened out
Compression increased in all cylinders of both vehicles, the spread between cylinders decreased. 9.1–20.6 % — compression by cylinder on both trucks, 22.2–26.6 → 25.9–30.0 (2001).

What repeated on both trucks
| VEHICLE | ODOMETER AT THE “BEFORE” READING | DISTANCE RUN BEFORE THE CHECK READING | WHAT WAS MEASURED |
|---|---|---|---|
| KamAZ, plate No. V 841 OKh | 37 951 km | 11 014 km | Compression by cylinder, oil pressure |
| KamAZ, plate No. V 814 EM | 49 134 km | 15 445 km | Compression by cylinder, oil pressure |
Compression by cylinder, right bank — both trucks side by side
| CYLINDER | V 841 OKh, BEFORE | V 841 OKh, AFTER | V 814 EM, BEFORE | V 814 EM, AFTER |
|---|---|---|---|---|
| 1st | 23.2 | 26.1 | 26.6 | 29.7 |
| 2nd | 22.5 | 26.6 | 25.7 | 30.0 |
| 3rd | 24.1 | 26.3 | 26.1 | 29.6 |
| 4th | 22.2 | 25.9 | 24.8 | 29.9 |
| Spread between cylinders | 1.9 | 0.7 | 1.8 | 0.4 |
The compression unit is not filled in on the report forms; the values are given as they stand in the documents. The rise occurs in all eight cylinders, with no drop in any of them.
Oil pressure in the lubrication system
| MODE | V 841 OKh, BEFORE | V 841 OKh, AFTER | V 814 EM, BEFORE | V 814 EM, AFTER |
|---|---|---|---|---|
| Idle | 1.6 | 2.0 | 1.9 | 2.4 |
| 2000 rpm | 3.7 | 3.9 | 3.8 | 4.7 |
Oil pressure in kgf/cm². At idle the “before” reading was taken at 45 °C, the “after” reading at 60 °C.
