If it becomes necessary to check the valve/ignition timing position of the engine, use this procedure:
With the engine switched off and electrically isolated, remove the rocker cover, Operation -.
2 Remove the cover (A2) from the flywheel housing. The top bolt (A) is the timing bolt.
Caution: If a customer-fitted speed sensor is fitted to the flywheel housing, it must be removed before the
engine turning tool can be inserted.
Remove the plug (A) from the timing bolt location in the flywheel housing and fit the timing bolt.
4 Insert the engine turning tool, CH48, into the flywheel housing through the aperture behind the cover
(A2). Use a /2 inch drive ratchet with the turning tool to rotate the engine flywheel in the normal direction of
rotation (anti-clockwise when viewed on the flywheel) until the timing bolt engages with the threaded hole in
the flywheel. The piston of number cylinder is now at TDC (top dead centre).

When the number one piston is at TDC on its compression stroke, the valves of number one cylinder will be
fully clos ed, if not, remove the timing bolt, rotate the engine by a further 60 degrees and insert again the timing
bolt. The piston of number cylinder is now at TDC on its compression stroke. Withdraw the timing bolt from
the fly wheel and rotate the engine backwards until the follower of the number one injector rocker lever is in
contact with the back of the cam lobe.
5 Attach a plunger clock and set the plunger on the top face of the rock er lever of the number one injector at
the position shown (B). Set the clock to zero.
6 Rotate the engine in the normal direction of rotation until the timing bolt can again enter the hole in the
flywheel and check the reading on the plunger clock. The cam lift at this point should be 2,92 +/- 0,25 mm
(0.5 +/- 0.00 in).
7 Repeat step 6 to ensure that a consis tent reading is obtained.
8 If the reading is not within the limits, adjust the position of the adjustable idler gear to advance or retard the
camshaft as necessary. Refer to Operation -. ,威爾信P40P3發(fā)電機(jī)配件,帕金斯曲軸價(jià)格,perkins噴油泵,沃爾沃柴油發(fā)動(dòng)機(jī)配件 專供,鉑金斯發(fā)動(dòng)機(jī)手油泵,帕金斯發(fā)動(dòng)機(jī)循環(huán)水泵,帕金斯電子柴油泵,哈爾濱哪里賣鉑金絲發(fā)動(dòng)機(jī)配件,四缸珀金斯發(fā)動(dòng)機(jī)缸體價(jià)格,能否買到帕金斯配件,帕金斯發(fā)動(dòng)機(jī)四缸機(jī)曲軸報(bào)價(jià)
