Dan107 Posted February 26, 2022 Author Share Posted February 26, 2022 I think in the morning I'm going to try and run my snake camera up from the bottom and see if I can find those timing marks. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/5/#findComment-490403 Share on other sites More sharing options...

fjh Posted February 27, 2022 Share Posted February 27, 2022 (edited) the dam timing tool bolts somewhere on the back with the rear cover piece removed unfortunately you can be one tooth out one way or the other with the dam thing at our shop we had to fight this a have dozen times! you have to check it with the computer after you have the engine running to confirm if it is synced! and ITS SO EASY TO SEE back there! 😡 Edited February 27, 2022 by fjh Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/5/#findComment-490426 Share on other sites More sharing options...
Joey Mack Posted February 27, 2022 Share Posted February 27, 2022 youre talking about the 'A' hole and the 'B' hole tool.. yep, got to have the lower timing cover off to do it. then you need 2 bars made by Volvo to press the cover back down in order to bolt it back in place properly... terrible... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/5/#findComment-490430 Share on other sites More sharing options...

Onyx610 Posted February 27, 2022 Share Posted February 27, 2022 Do you have fleet impact? If not I’ll look up the procedure on one of our MP8s on Monday.

Joey Mack Posted February 27, 2022 Share Posted February 27, 2022 I know one thing... He will need a half a reem of paper and extra toner to print the book on just this portion of the repair.. I know... I did it. In total, I believe I have about 400 pages (single sided) on just the MP-8.. In my library I have books that thick, but they cover MANY versions of the engine. anyway, it's great that you have access to this info.. jojo 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/5/#findComment-490435 Share on other sites More sharing options...

Onyx610 Posted February 27, 2022 Share Posted February 27, 2022 I think he will get this done, I’m sure a lot of people have done it without the tools and been ok. Also on the other hand I’m sure a lot of people have done it without the tools and weren’t ok. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/5/#findComment-490444 Share on other sites More sharing options...

Are you talking about the large inspection hole or the small bung hole, and is it a dimple mark on a tooth, or a hole in the flywheel I’m looking for? I should have marked this stuff before and this is a prime example of what happens when a person gets in too big of a rush!

Joey Mack Posted February 27, 2022 Share Posted February 27, 2022 (edited) the little broken hole... my guess is someone tried to bar the engine over with a small pry bar or big screwdriver.. You will see a zero on the flywheel edge. that sets the engine to TDC on #1.. then when you place the cam, you set the cam to TDC.. theres more to do but that is the basics of it.. I expect MackPro and 'V' to join in on this and fill in my blanks... jojo Edited February 27, 2022 by Joey Mack Poor spelling 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/5/#findComment-490477 Share on other sites More sharing options...
fjh Posted February 27, 2022 Share Posted February 27, 2022 (edited) That there is where you need to start in my opinion .good starting point Joe! the hole in the top may have also been a failed clutch brake at some point as well! seen this happen many times! one of the few things I have done on the red engines I have been in ivolved in physically and not a silent observer!

You just need to follow the procedure. Watch the video if you don’t have it. I also sent you the procedure for replacing all the gears and no where in there does it say anything about marking them or timing the idler gear. If the crank is at tdc, your cam is at tdc, and your cam gear is lined up with the the mark on the head your engine is timed.

It is very easy to be off one tooth one way or the other from my observation ! Our guys struggled with this more than once just sayin! Use that keen eye bud ! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/5/#findComment-490484 Share on other sites More sharing options...
