    Default Hewland part ID

    I have a few parts I'm not sure about so hopefully you guys can identify.
    I don't see a listing anywhere for an 8/33 ring and pinion but here one is. Also appear to have fixed 1st for a 4-speed. I think the 5-speed has the reverse and 1st gear closer together and could be either Mk9 or Mk5 gears. I know that Mk5 and Mk9 gears aren't interchangeable, just wanting to confirm what these are.
    TIA

    8/33 ring and pinion is VW and used in older Hewland MK6. MK8/9s had Hewland manufactured item.

    Yup. Ring gear and pinion from an older Mk6 Hewland which used stock more stock VW parts, namely a stock VW differential, ring gear and pinion shaft. The 8:33 is a real stump puller Have it in my Bobsy FF. And to use taller gears to get my same speeds, etc vs a Hewland 9:31 diff. (e.g. a 26/25 4th, one over, top gear to get same results as a 24:27 in a 9:31 box.). All the hubs that slide on the pinion are unique. I think they were made by Hewland but made to work on the stock VW pinion shaft.

    The bits ty-rapped-together is a set is a low ratio 1st gear. It has the lay shaft slide on part also having the reverse idler drive gear integral. A much stronger set up for such a low ration gear set which if separate would be very, very thin and will probably break. Cool set up, but requires a lay shaft without the integral reverse slider built in.

    As to the odd lay shaft and gear, I have no idea what that is.

    Bob is spot on again. 8/33 was popular in the 1 liter F3 cars where the same 115 Hp that your FF Kent makes at 6500 rpm was made at 9500 rpm with no torque. Just ask Andy. Todd
