timing gear & 1 7/16" socket

[moggieman]

Does anyone have a steel timing gear for a B18 they could sell me? I think my fibre gear may have gone but don't want to spend £120 on a new one just in case it hasn't. I'm also looking for a large 1 7/16" socket to undo the nut that holds it on. Thanks, David

I think the going rate for steel timing gear is about $200 USD or 120 pounds. if you have torn into the engine far enough to get the fiber gear off, then you should go to steel. I have had fiber timing gear last 60,000 miles and others sets, blow up on start up of a rebuilt engine. Therefore, I don't use fiber anymore, even on stock engines.

As for your other post about getting the old one off, you should be able to turn the nut off (you may have to put the car in gear, parking brake on) and use a small 3-jaw gear puller with the fingers in the three holes in the face of it. I have never had a gear that I could pull off with out a puller. It's not a hard pull but you need one. Check the brass cam retainer plate for wear while you are in there. There are not available from Volvo (north american anyway) anymore but if you bug your local Volvo Penta dealer they still have them and it's the same part number. Also if you are going to reuse the old gear, make sure it has timing marks on it and/or check the new one for timing marks before removal of the last one to make sure you get things lined up again.

Good luck!

Thanks - it's good to know how do it it. If things get that far, I would replace with a steel version.

I may have a steel timing gear in the garage. I will have a look

Is it true that the steel timing gear is more noisy than the fibre ones? That might be a consideration.

You can't just swap over the steel timing gear as it needs a matching crank gear. The teeth are different. Change as a set.
Noise increase varies but if it's loud just say it's your supercharger.............

Personal experience is that the first 500-1000 miles there is more of a metallic/tinny/wizzing noise to it but after that it quiets down and you really can't notice. Also if you are in there, make sure the brass elbow that sprays oil into the bight of the gears is clear. If that sprayer plugs, you get undue wear in the gears (fiber or steel).

And yes, you should swap the gears as a set. Most times the teeth are different anyway as Derek said...

a 32 mm spanner will fit the nut if that is of any help. As above, I found that I had to put the car in gear with handbrake on to fix cam and crank before turning the nut. Don't over-tighten the nut when ref-fitting or you will end up having to replace the cam as I did !

I hardly noticed any increased noise.
