Checking Timing

Postby moneypit » Thu Mar 26, 2015 1:40 pm



How do I check the timing on my 1100 I don't see any DIY articles. Is it important to check after changing Timing belts..

Assuming you didn't allow the cam sprockets to rotate when the belts were off, and made sure the arrows were all in alignment again when you put the new belts on, there is no reason to check the timing.

All you can do after changing the belts is to slowly rotate the motor by hand to check for interference from the valves, if it rotates freely, then your good to go. Regards, Johnny

With all respect, you can check your timing with a timing light as shown in the manual, you can confirm the timing using a inspection sight cap and a timing light...Note: if you are on all your cam
marks you are good to go as admin. mentioned.....I have done this many times and I have checked my advance with the timing light at the pulley while the engine is running... My good friend told me I need to get out more.. :lol: trying to see the advance throught the inspection cap is near impossible because the oil is flying around at a higher rpm,, that's why I check it at the pulley...I have videos of this somewhere.. But you can see the f-1 mark fine at idle with the inspection cap, it's when you turn up the speed is when you can't see the advance marks..

You can really see the F-1 on at idle with a inspection cap.. The trick is to do this in the dark, you see it better.....

A very good idea!
I can see where using a timing light would be helpful in finding fluctuations in the timing that would indicate vacuum problems, and not to knock your idea, but assuming that all the timing marks are lined up correctly (shafts, crank, etc. ) to begin with, it seems a little redundant to use a timing light?
I just cant see an advantage. Regards, Johnny

I noted that too....If someone wishes to check the timing without doing the belts this is a easy way to check... :D also it's total confirmation that his job is correct..... His question is, Is it important to check the timing after the belts have been replaced,, I would, but it's not necessary, I just like checking it to make sure.....I am showing him how...He asked How do I check my timing? I just answered the question he asked... :D Just remember you are looking for F-1 when using the light,, T-1 when setting the belts, have a great day.. Oh yeah,, if someone is off a tooth before he removes anything you will see the difference with the timing light on the F-1mark, it will be off the mark...Not lining up exact...I can tell you if both cams are aligned before starting the belt job..LOL
