Aligning Timing Mark Plate Thingy On The Head.

[Gameboy]

This stupid thing movies around to much. Any tips on bolting it so its 100% accurate so I can do the belt correctly?

How much is too much? It has 3 bolts that locate it so it really shouldn't move that much. Unless someone has increased the size of the locating bolt holes in the backing plate on yours, any amount it moves wouldn't be enough to worry about.

Or the rubber gromets are missing

It also aligns via the cams. So that's 5 holes to align it too. Surely you can figure it out.

My money is on this, or they are worn. There is not really that much play in the backing plate when the rubber washers are fitted and in good order.

this is how I get it aligned..

set all cam gears into the exact location, then put belt over it and cable tie it on temporarily as you put the belt over the idler/tensioner & crank. Once everything "looks" ok.. remove cable ties and crank the motor by hand (remove the spark plugs as it's easier).. do it a few times clockwise only.. then check again..

Once she's sweet, nip up the tensioner nut.

I think he is talking about the backing plate?

clearly I didn't read the post properly lol

There should be rubber grommets and then steel washer inserts which press into the grommets. Last I checked there are four bolts that hold the backing plate to the head, that was on an rb25 head, 20 or 26 could be different.

There isn't enough slop in those bushes and grommets to be a whole tooth out. If it is bad enough that is the case, then you should try and get new grommets and inserts and hopefully that takes out some of the slop.
