KEP Kennedy Presure Plate problem

[larrym]

anybody seen this before? Solutions ??

I have a new-in-box KEP-1 pressure plate that I purchased thru GPR of San Luis Obispo (German Parts & Restoration) as part of a complete FW-Clutch conversion package to fit a 901 transaxle to a 3.2 engine

the GPR invoice - says part number "916-116-911-00 clutch set - 901 - 225 kit" and the FW is 930-102-033-01

today I finally tried to install the clutch

the bolt holes are not matching - the edges are about 1.5-2.0 mm inset from the matching bolt holes of the flywheel -

impossible to bolt up unless I hog out the existing holes in the KEP-1 PP

further measuring shows that the OD of the KEP-1 PP is maybe 1.5-2mm mm larger than the ID of the Porsche ring gear

- it would require a big hammer or some grinding on the OD to make this fit correctly

what do you suggest I do in order to make this thing fit?

or did GPR sell me the wrong PP ???? (see UPDATE below )

the label on the box only has the KEP logo and "Stage 1 228mm VW/Porsche Presure Plate" printed on it

update -

I sent the PP to Kennedy - and - it turns out the PP I have is the correct Porsche diaphragm, but the incorrect bolt holes - (? go figure how that happened) - The Kennedy box says 228 - but the PP inside is a vw bus 225 bolt pattern - (a shipping room error somewhere... ?) - so apparently the GPR kit was a mismatched set of parts -


update

A. Kennedy says there are TWO PP differences:

1. the bolt holes issue (they elongate them (the say "notch") to solve this) and
2. the diaphragm fingers on the correct one for Porsche have no flats at the T/O brg

B. There are also differences in the bolt-on adapter ring and starter ring gear

1. their early version was a one-piece adapter/gear - the PP was designed to be a very tight fit inside that ring, so there were no PP locating pins needed - that supplier went away

2. their current newer version is a 2-piece ring with a replacable ring gear; it uses locating pins for the PP, and the therefore the PP is not a tight fit in the ring - (price for this later type item is $170)

the "225" version without notched holes, and with flats on the fingers, is for VW Bus setup (914-4s may use this)

Kennedy is fixing this - notching the bolt holes on my PP - no charge - - hurrah !!!!

C. we discussed the "apparent oversize of the PP diameter - they say that it "should pull into position" with the bolts for a very tight interference fit

I have a brand new KEP pressure plate in the box waiting for install this Winter on my G50 3.2i'll have a look this evening and see if i could find a Part Number ...

Cheers !

i would call monty at kep and explain the problem. i would not modify the new piece.

Here is the P/N from my invoice which is a 3.2 application for a G50 gearbox ...
Regardless if you're mating a 901,i would think the clutch and PP have to match the 3.2 flywheel !
The OD of the pressure plate surface is 9 7/16 and there is no part number stamped on it ...

Hope this helps !

Cheers !

Larry, if you are using a G-50 3.2 flywheel, you need a 240 mm clutch. If it was mated to a 915 box, then it will be 228 mm.

[larrym]

the entire FW-PP-package was a 901 kit from GPR

it is a 228mm - it is not an oem 3.2/g50

I do have the oem g50 stuff - not usable in this situation - 'way different setup

update - I just found the GPR invoice - it says part number "916-116-911-00 clutch set - 901 - 225 kit" and the FW is 930-102-033-01

so apparently the GPR kit (the PP, clutch & ring gear) was a mismatched set of parts

here is important info from a 914World post

- 914World.com - A Porsche 914 Community / Forum / Club

"The 225 kit does use the 228mm pressure plate, the holes do need slight enlarging (elongating), but it's the adaptor ring that holds it centred in place. You shouldn't have to this as it should be done so let the seller look at it before whipping the drill out."

one step forward, 2 back - i'm getting too old for this

problem solved - see added edits in original post above

(fwiw - the Patrick soution to this conversion is not made the same way)

C. we discussed the "apparent oversize of the PP diameter - they say that it "should pull into position" with the bolts for a very tight interference fit - but maybe i'll have to chuck it on the lathe for trimming the OD if not
