Timing belt replacement (B16A2)

**omgzilla** · 02-02-2008 03:45 PM

Doing the timing belt on my EK4 (manual) and just wondering what is the best way to lock the engine once its set at TDC? ...whilst trying to remove the crank pulley.

Theres a plastic tool that Bursons sell

U place it between the two cam gears and as u spread it out it locks into the teeth on the gears and then you tighten so that they dont slip

EDIT Pic

This one appears to be metal

theres markings on the engine shouldnt need to lock it just make shore you find the markings

He was wondering how you get it to not slip once you match the cams and crank with the markings?

It does happen sometimes that once you set it to TDC and you maybe knock a gear and it springs off of TDC

Thanks for clearing that up Drew.

I am trying to lock the engine so that it is locked on TDC so I can then remove the (very tight) crank pulley bolt - without the engine moving from TDC.

Any other suggestions than the cam locking tool?

Not really no

In the rocker assy rails there are 2 holes, 1 will matchup with a hole in the cam, put a punch or similar thru and it will lock the cam.

Agreed, the holes are there to align the cams instead of using the tool listed above...
But I disagree they could be used to lock the engine & undo the crank bolt.
IMO this would likley cause damage to the engine.

omgzilla, have you tried putting it in gear & having a freind stand on the brake pedal while you swing off the crank bolt with a large breaker bar with an extension added?
Failing that, you may have to get to someone with a large enough rattle gun to do the job.

Thanks Edge and Toda!

Will give the breaker and friend helper thing out on Monday arvo - had thought of this previously but thanks for the tip regardless.

Might have to bring home my rattle gun and borrow a compressor. Will my 500ft/lb gun be enough for the job?

NP...
500ft/lb gun should do the trick...
Just be sure it's oiled up & there's plenty of pressure.

LOL i guess i should have read the post properly. that is only to lock the cam to keep them in place while the belt is off. there are a few tools out there to lock the crank pulley like this 1 http://www.youtube.com/watch?v=RE-pzP8g_x4 . a tool like this should also be use to torque up the crank bolt when installing it.

Awesome! Might have to grab one of these tools!

The place that sells them: DenLorsTools also have a sweet Valve Adjustment tool!
