PFA - does anybody know if the synchro / baulk ring set from a 5 speed TY754VB7AA are the same as a 5 speed TY752vb3fa ??

Cheers

Don Clark

At a quick glance no.

TY752VB3FA - 32650AA001
TY754VB7AA - 32650AA032

Which given that TY752VB3FA is a Revision C classic box (1995/6) and TY754VB7AA is a Revision F newage box (2005/6) seems to make sense.

Excellent thanks for confirming, i did have my doubts but hoped all 5 speeds used the same, never mind !

Do you have the part number for the baulk rings ? To help my search begins to see if i can actually purchase baulk rings/syncro for a vb3fa ( 1995 wrx ) gearbox..........

The 3FA box was only fitted to the revision "C" WRX between dates below

(equates to MY05)
Revision C models were built between

so for two "model years"( which roughly equates to MY95/96).


However as Rallyspec assemble kits (although they don't specify which subaru part numbers are included) that would be the way to go.
Before purchasing it may be worth enquiring with them what kits would actually be needed for your specific 3FA box but from what you have listed would appear to be suitable.

Hi Dom, Many Thanks,Just to confirm with you , Rallyspec have said i need parts

RSTR-1091B = 32652 on Driven Shaft Diagram
RSTR-1092B = 32650 on Driven Shaft Diagram (includes all 3 pieces)
RSTR-1095B = 32614*B on Main Shaft Diagram ... used for 3rd, 4th, and 5th gears.

Do you agree, those are the only parts i need to order to fit new synchros /baulkrings to the shafts to the ty752vb3fa (1995) ?

Don Clark

That would be the 64K dollar question.
I would imagine it depends what you find as you take it all apart.

Possibly the shaft lock nuts and washers listed below

Ha I hear what you are saying - but in theory are those parts the synchros / baulk rings ( I’m not looking to replace bearings or anything else )

Don Clark

I missed off a lockwasher in list above



same part numbers as UK Turbo 2000 5MT

Excellent appreciate the assistance bud, about to order all those bits, about £190 delivered ( minus custom charge )

Then its onto a company that can fit the synchros onto the loose shafts i have removed from the box, i would attempt myself but i have no way or idea on how to undo the locking nuts whilst stopping the shaft rotating ( Guess you set up a jig to hold the gears /lock them whilst you undo the nut )

cheers
