98a omega 2.5 125kw v6 manuaal

keegi kindlasti ise teind ja äkki jagaks teadmisi minuga,et kiirelt ja effektiivselt ligi pääseda,ilma et üleliigseid asju eemaldaks....
hea oleks kui puust ja punaseks ehk step by step :mrgreen:

Kui inglise keelt jagad, on vastus siin (Haynes):

Camshafts and followers - removal, inspection and refitting
Removal
1 Remove the camshaft cover as described in Section 4.
2 Remove the camshaft sprockets as described in Section 8. If the right-hand cylinder head camshafts are to be removed, rotate both the inlet and exhaust camshaft backwards approximately 60°; this will minimise the valve spring pressure being exerted on the bearing caps and so lessen the risk of damage as the caps are removed. The left-hand cylinder head camshafts are best left positioned at TDC.
3 Starting on the inlet camshaft, working in a spiral pattern from the outside inwards, slacken the camshaft bearing cap retaining bolts by half-a-turn at a time, to relieve the pressure of the valve springs on the bearing caps gradually and evenly. Once the valve spring pressure has been relieved, the bolts can be fully unscrewed and removed along with the caps. The bearing caps and the cylinder head locations are numbered to ensure the caps are correctly positioned on refitting; an identification letter is also stamped on each cap (see illustration). Caution: If the bearing cap bolts are carelessly slackened, the bearing caps might break. If any bearing cap breaks then the complete cylinder head assembly must be renewed; the bearing caps are matched to the head and are not available separately.
4 Lift the camshaft out of the cylinder head and slide off the oil seal. Using a dab of paint or a suitable marker pen, make an identification mark on the inlet camshaft to avoid getting the camshafts mixed up on refitting; the inlet and exhaust camshafts are the same but it is important they are not interchanged as this will increase the rate of wear.
5 Repeat the operations described in paragraphs 3 and 4 and remove the exhaust camshaft. If the work is being carried out on the left-hand cylinder head, prior to removing the bearing caps, unbolt the camshaft sensor (see Chapter 4A, Section 14) and position it clear of the front bearing cap and free the knock sensor wiring.
6 Obtain twelve small, clean plastic containers, and label them for identification. Alternatively, divide a larger container into compartments. Lift the followers out from the top of the cylinder head and store each one in its respective fitted position. Note: Store all the followers the correct way up to prevent the oil draining from the hydraulic valve adjustment mechanisms.
7 If necessary, repeat the operations described in paragraphs 1 to 6 and remove the camshafts and followers from the other cylinder head. If all the camshafts are to be removed at the same time, make identification marks on the shafts to ensure they are refitted in their original locations, and note the camshaft bearing caps identification letter locations to ensure the caps are refitted to the
correct cylinder head.
8 Examine the camshaft bearing surfaces and cam lobes for signs of wear ridges and scoring. Renew the camshaft if any of these conditions are apparent. Examine the condition of the bearing surfaces both on the camshaft journals and in the cylinder head. If the head bearing surfaces are worn excessively, the cylinder head will need to be renewed.
9 Examine the follower bearing surfaces which contact the camshaft lobes for wear ridges and scoring. Check the followers and their bores in the cylinder head for signs of wear or damage. If any follower is thought to be faulty or is visibly worn it should be renewed.

Refitting
10 Where removed, lubricate the followers with clean engine oil and carefully insert each one into its original location in the cylinder head.
11 Lubricate the camshaft followers with clean engine oil then lay the camshafts in position. Ensure the crankshaft is still positioned approximately 60° BTDC then temporarily refit the sprockets (see Section 8 for details) to the camshafts (see illustrations). On the left-hand cylinder head position each shaft so that its sprocket timing mark is aligned with cutouts on the rear cover and on the right-hand cylinder head position each shaft so that its sprocket timing mark is approximately 60° before the rear cover cutouts. This will position each camshaft so that the valve spring pressure will be equally exerted along its length as the bearing caps are tightened.
12 Ensure the mating surfaces of the bearing caps and cylinder head are clean and dry and lubricate the camshaft journals and lobes with clean engine oil.
13 Apply a smear of sealant (Vauxhall recommend the use of sealant 15 03 170 - available from your Vauxhall dealer) to cylinder mating surfaces on each side of the camshaft oil seal apertures (see illustration).
14 Refit the camshaft bearing caps and the retaining bolts in their original locations on the cylinder head. The exhaust camshaft caps are numbered 1 to 4 from front to rear and the inlet camshaft caps 5 to 8 from front to rear with the corresponding numbers being marked on the cylinder head upper surface (see illustration).
15 Working on the exhaust camshaft, tighten the bearing cap bolts by hand only then, working in a spiral pattern from the centre outwards, tighten the bolts by half-a-turn at a time to gradually impose the pressure of the valve springs on the bearing caps. Repeat this sequence until all bearing caps are in contact with the cylinder head then go around and tighten the camshaft retaining bolts to the specified torque (see illustration). Caution: If the bearing cap bolts are carelessly tightened, the bearing caps might break. If any bearing cap breaks then the complete cylinder head assembly must be renewed; the bearing caps are matched to the head and are not available separately.
16 Tighten the inlet camshaft bearing cap bolts as described in paragraph 15.
17 If necessary, repeat the operations in paragraphs 10 to 15 and refit the camshafts to the opposite cylinder head.
18 Fit new camshaft oil seals as described in Section 9.
19 Refit the camshaft sprockets as described in Section 8.
20 Ensure the camshaft sprocket timing marks are all correctly aligned with the cutouts on the rear cover then carefully rotate the crankshaft in the normal direction of rotation until the sprocket mark is correctly realigned with the notch on the oil pump housing.
21 Refit the timing belt as described in Section 7.
22 Refit the camshaft cover(s) and timing belt cover as described in Sections 4 and 6.

Huvipärast uurin,et kas omegal tuleb hüdrotõukur lihtsalt tõmmates oma pesast ära.Kas mäletan õigesti et omegal hüdrotõukur pöörab töötamise ajal ümber oma telje(ühtlase kulumise eesmärgiga)?

Tõukuri "mytsid " tulevad lihtsalt ära.Siiani nähtutest ei tea küll miskeid imekanaleid mis mida keerutaks seal.Aga hea mõte uurida seda edasi.
Mina võtaks plokikaane maha ja vahetaks tihendid jne ka ära juba.Nukad pead enivei maha võtma
