Flywheel for 6-conversion to 901 gearbox, Vendors disagree on part no. Options

[rwfms]

(IMG:style_emoticons/default/agree.gif) the starter stock is more than enough,Bosch make great starters when I reconditioned them years ago most only needs a clean and lube,the worst I found needed commutator machined and new brushes and these were old starters back then,save the reduction high torque starters for high comp petrol motors and diesels (IMG:style_emoticons/default/dry.gif) .
Sounds like the OP may have had a flywheel with no induction hardened teeth...easy to check with a hand file the tips should be bloody hard.

Thanks for the tip. I'll let you know when I get the gearbox out.

I think Root Werks is right about the timing marks on the flywheel. I haven't confirmed that with the vendor but I will.

I prefer the 74- up 911 starter. The starter is 1.5 hp, almost twice the horsepower of the .8 stock starter. Plug and play.

be aware - there was a run of those 1.5 starters that had a "thin" nose bushing - which tended to crack - resulting in chewed-up ring gear

i trashed 2 new 914-6/901 flywheels with one of those 1.5 Bosch starters (that i b'ot new) before i found that cause on a pelican thread - i no longer know the link but it was circa April 2012 after i posted the message below:

- you can just get the ring gear replaced by RIMCO - they do a nice job and understand our stepped flywheels http://forums.pelicanparts.com/porsche-911...ear-repair.html

i now run a genuine IMI HiTorq on my 3.2 - and on my 454 chevy - both b'ot on eBay

- if ya just want a good used higher torq oem 3.2 Bosch starter ('89) - i have one on shelf FS
