Bens bosch conversion dont use the wrong key!

If you can get bolts in with it a tooth out when your cross threading the bolts in / bolts are going in at an angle, they will not go in with a tooth out if you have the belt tensioned correctly.

Exactly what I mean, they will go in a turn or 2 but wont thread in properly. Still enough for some people to think they line up though, when really they dont. Thats why you should always screw the locking bolts in as much as you can imo

I spend a friggin week dismantling pumps only to realise it was just a tooth out... but the bolt still went in a few turns!!! :nope:

Id disagree with Mark (dangerous, I know....) about the holes lining up if it was 1 tooth out. Dave will vouch for me in saying that even when they are 1 tooth out it can be possible to get the holes to 'nearly' line up, and you can get a bolt in a couple of turns. Make sure the bolt you are using to check the locking holes screws in a good 6/7 turns!

And I cant see how you could get the pump 180 out. It has 2 locking holes, one at 12 o clock and one at 4 o clock. Its worth checking though that you havent put a bolt through the 12 o clock hole in the pulley and screwed it into the 4 o clock hole on the pump bracket? Which would make it ~ 120° out.......

What I mean is the pump is 360 out meaning instead of compression strok it would be exhaust

But your cam will change the compression stroke to exhaust stroke if its timed up correctly
