Hi all,

I finished disassembling the transmission of my spider S4 and it's time to decide what parts to replace.

In particular, the 5th gear shows a nick that seems to be caused by a foreign object - I couldn't find the offender though.

Before opening the transmission the gear didn't give any particular trouble and it wasn't noisy, at least I never noticed it.

Do you think this gear should be replaced? The problem is, it's not the only one having this problem...

Thanks!
Ciao,
Enrico

The person to give you a positive answer (and he probably has the gear) is Alfar7 here on the BB. The question is, what does the mating gear look like?

Gear ding

If the majority of the gear tooth in question is smooth and there is no "raised" surface ridge I would not be overly concerned.

Dear Gordon Raymond and AlfaR7,

thanks for your feedback.

I'll inspect more closely the layshaft gears and the other output shaft gears and post my findings.

Thanks again,
Enrico

Hi,

I didn't have time to go to the garage in these days as everything and more happened! So I still don't have the pictures of the layshaft gears as well as the other gears to show.

I'm not sure if the mark looks like it was done with a grinder. This is a good question, I read that sometimes at the factory they grind the gears to get rid of some defects but I really don't know if this applies here. Maybe somebody more experienced with Alfa gears can add his feedback.

Thanks.
Ciao,
Enrico

Layshaft 5th gear ding

Hi,

I inspected the layshaft 5th gear and found another ding. I don't think it's the twin of the output 5th gear ding shown above because they seem to be on the opposite side of the gear.

The other gears solid with the shaft don't have any mark, fortunately.

I look forward to your opinion on what to do with these gears.

Thanks.
Ciao,
Enrico

A chip. Clutchless shifting. Grinding gears. Whatever. Possibly the errant chip caused the other dent? This is another one not to worry about. Check with Alfar7. MAYBE he will agree with me!

They look like recent grinding marks, someone has been in there before you. Maybe the butler did it? its very recent.
Put it together it will be fine.
