Re: [MBZ] OM603 camshaft installation
It certainly makes sense to me to follow the center-out tightening sequence for the final torque down.

Re: [MBZ] OM603 camshaft installation
Hi Luther, One thing about the torque sequence - typically, it's best to start in the middle and work towards the outside.. Hmmm... I'm havng trouble finding a way to dcscribe it... if the cam cover looks like this - with the #s being bolts -- 1 - 2 - 3 - 4 - 5 - 6 7 - 8 - 9 - 10-11-12 1st, snug one of the middles - 3,4,9 or 10. then the one opposite/other side - say you did 3, the next would be 10, then 9, then 4, then 8,5,2,11,1,12,7 & 6. That way, the surface will be kept smooth as any imperfections will be pushed to the outer edges with the tightening of each fastener, It's probably too late for you, but it should be disassembled in a similar sequence.

Re: [MBZ] OM603 camshaft installation-success!
R&R of the cracked head. I installed the bearing caps in the exact order they were removed, they are numbered 1-7. Thank goodness :D Bearing caps 2,3,4, and 7 were installed 1 turn per bolt at a time. I'm thinking that the mechanical interference is not enough lube/metal on metal. That's why I'm going to take it off and put it back on with lube. If I do it right, and there's still an issue, I have bigger problems. This is my first head R&R. All I'm doing is following the manual word for word. Hasn't been tough until this point.

Re: [MBZ] OM603 camshaft installation-success!
I just had another thought. If it the engine really is harder to turn than it was when you lined up the timing marks then you may have a lubrication problem with the cam bearings. Problem is, if you do than you may have already scuffed the bearings & if you have then they will wear out quickly.

Re: [MBZ] OM603 camshaft installation-success!
It should take some effort. You are turning the cam, the oil pump, opening the valves, operating the IP and taking the pistons through their compression stroke. The last time I turned a diesel over by hand, I was checking timing chain stretch and it was hard work. Can you take it through 2 complete revolutions without coming to a hard stop?

Re: [MBZ] OM603 camshaft installation-success!
He replaced the head. Cam bearings are two bolts, and must be "walked" down one turn at a time on the four or five bearing caps specified in the shop manual to avoid warping or binding the cam.

Re: [MBZ] OM603 camshaft installation-success!
Hey Luther, Why was the cam removed? What other parts were removed? The engine should turn over using a wrench on the crank bolt. If you cannot turn it there, the starter won't turn it either. I looked at the 603 manual & it appears the cam hold downs are held in place by a single bolt? The sequence of tightening these bolts is important to get an even pressure on the cam.I haven't kept all the posts to this thread - I seem to rememebr you teling us how you tighten the bolts slowly -- I assume you made sure the cam bearing housings went back on in the same order? Please don't be offended by my questions - if they seem basic its only because I don't know your level of expertise on this stuff - Toms right, the Mobil 1 is not the problem. The only thing that will prevent the engine turnng is a mechanical interference - Good luck - Larry T (67 MGB, 74 911, 78 240D, 91 300D) www.youroil.net for Oil Analysis and Weber Parts Test Results http://members.rennlist.com/oil PORSCHE POSTERS! youroil.net Weber Carb Info http://members.rennlist.com/webercarbs . - Original Message - From: "Luther" <[EMAIL PROTECTED]> To: "Mercedes Discussion List" Sent: Friday, August 10, 2007 1:55 PM Subject: Re: [MBZ] OM603 camshaft installation-success! >I was attempting to turn the engine over by the crank with a 27mm socket >and ratchet.

Re: [MBZ] OM603 camshaft installation-success!
Well, something has to be stopping it all from rotating. The timing chain goes around the injector pump, vacuum pump, crankshaft and then the camshaft. There are a few chain guides too - the two between the injector pump and the camshaft just site there, while the one on the other side applies pressure to tension the chain. Maybe loosen the chain tension and see which still have some wiggle in them? You can get to the injector pump gear underneath the vacuum pump. -Dave Walton On 8/10/07, Luther <[EMAIL PROTECTED]> wrote: > Sure, but it's how I set the valves on my OM617s AND how I set this engine to > TDC before I removed the old head.

Re: [MBZ] OM603 camshaft installation-success!
Should be fairly easy to rotate a 603 -- if quite stuck, something is very wrong. I would remove the cam and make sure you have #1 on TDC. Check the installation, too -- if you got it sorta cocked, it may not turn because it's bound. It's not hard to turn the cam with a large screwdriver inserted between the hub and locating pin.

Re: [MBZ] OM603 camshaft installation-success!
You must follow the directions with Assembly Lube, as with everything else - some people operate on the principle of "if a little is good a lot is better" - not with assy lube - when applying the assy lube make sure you use a small dab and rub it in good - a blob can stop the flow of oil. And that's when problems start. As Tom says, oil works as long as you have a good film. Another method that helps is to leave spark plugs / glow plugs out and disconnect the ignition/main power line so the engine will not start - then crank until you see oil pressure on the gauge. Good luck.

Re: [MBZ] OM603 camshaft installation
On the 4 cylinders, a piston hits tdc every 180 degrees of crank rotation. On the cam, since it turns at 1/2 the crank speed, an intake (or exhaust) valve opens every 90 degrees. When the cam is not restrained by the timing chain, it will rotate to a position between the lobes. What I found by trial and error on the OM621 engines was that if I set the crank at 45 BTDC I could put in the cam and timing chain, and install the IP because the cam and IP would be close enough to the resting position not to run away, and the crank was close enough I could get the timing from there. When I did the valve seals on my 603, I believe I put the crank on tdc, then put in the cam and its sprocket, and turned the sprocket by hand or with a socket on the nut to line up the timing mark and wrapped the chain on it. I'm sure it was a bit of a tussle to hold the cam and get both halves of the chain over the sprocket and get a connection link in, but I don't remember it being as bad as replacing a M103 water pump. Congratulation of figuring out the combination that worked! Loren At 12:35 PM 8/9/2007, you wrote: >Anyone have experience installing camshafts? I can't keep mine at >TDC when I'm tightening it.

Re: [MBZ] OM603 camshaft installation-success!
Oil is fine as long as you are sure that you have a good coating during assembly. The risk with oil is that so much may run or drip off that that you don't have a good oil film in the bearing. But this is not likely if you oil & then assemble right away. A lot of people like assembly lube because you can verify visually that there is enough on the part.

Re: [MBZ] OM603 camshaft installation
Once everything is together - timing chain in place over camshaft - the timing mark on the camshaft should line up with the crankshaft at TDC. The timing mark is on the camshaft, not the gear. You can then rotate the engine with a socket on the crankshaft. There will be a noticeable and dangerous lurch of the timing chain when the vacuum pump clears top position and it's spring pulls it back down forcing the timing chain along with it. If the camshaft timing mark does not line up, I was able to remove the chain tensioner and get enough slack to move the timing chain over the camshaft gear one link at a time. This is a good time to check on the timing chain stretch. There is no adjustment if the marks do not line up other than to replace the timing chain. Don't try to rotate the engine if the marks do not line up. The resistance may be due to the valves hitting the piston. Hope this helps... -Dave Walton On 8/9/07, dave walton <[EMAIL PROTECTED]> wrote: > Remove the vacuum pump. It's return spring is what keeps the timing > chain from moving freely.

Yes, I am tightening all 8 bolts 1 turn before going through the sequence again. I've been working on it nearly 2 hours this morning and cannot get it to hold TDC. Advice? TIA all. -- Luther KB5QHUAlma, Ark '87 300SDL (272,xxx mi) head case '85 Ford F250 6.9 diesel (x58,xxx mi) '82 300CD (166 kmi) '82 300D (74 kmi) getting donor engine-sold '85 300D (280,176) parts car sans engine ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
