VD Honda conversion

[LenFC11]

i recieved the kit last wednesday. honda does a very nice job across the board, very pleased so far.

everything is moving along well, but hit the first snag, i'm hoping maybe someone can help. seems the HPD adapter for the clutch slave cylinder was designed around the tilton unit. my car has the standard vd unit. is there any way to use the standar vd unit? if not does anyone know which version tilton is used?

thanks

If Tom Groshart @ HPD doesn't have that information contact Doug Brenner @ Brenner Fabrication in California. HPD modeled his car for the VD conversion. If you can't find Brenners number send me an email and I'll send it to you.

Len,

I may have a deal for you. I have a Tilton unit for '99 - up VD. It is used. Has been sitting on the shelf for 5 years. Do not know the history. But, the complete rebuild kit from Pegasus is only $40.

$115 shipped to you, if you need it.

yep tom responded to email. said ineed Taylor race engineering PN0200786


mike

any way you can confirm this is the part i need? seems there are two different tilton units, one for f2000 one for f1600. something to do with twin clutch or clutch size, i'm not sure..

but if it's the one i need i'll take it

thanks for all you input

Len,

It is Tilton part number 61-7725 with 44 mm release bearing.

Of course the current on-line Tilton catalog doesn't show any of them.

Taylor and Pegasus have their own part numbers.

Maybe someone at Taylor or Honda can tell you if it is the one you need.

I believe that is a picture of a standard VD unit, not a tilton unit.

A tilton looks more like this:

David:

Your photo is of one type of Tilton HRB (the 800 series). They have at least eight different series, and multiple versions within each series, and they also do custom units for specific applications. The p/n Mike Eakin quotes isn't on their dealer price list, so I assume it is custom for the Van Diemen, and may not even be available any longer.

Nathan,

It is just a generic picture of a tilton unit. The VD conversion unit looks similar to that. The one in Frog's picture is a stock unit, as you can see it is very different.

I haven't seen the Tilton conversion version, but if I understand you correctly it looks completely different from the stock HRB. Maybe Mike has a stock unit in a Tilton box?

thanks again for the help fellas.

the part needed as per tom at hpd is Taylor race engineering PN0200786 at this point i am trying to find out if the unit mike has will work or if i need to order the taylor unit. anyone know this ofr sure?

mucho graci'

I talked to Scotty at Taylor. The part I pictured is indeed the original VD unit, not the Tilton unit. I got the box in a crate of used stuff. It appears someone changed out the VD unit with a Tilton unit, and put it in the Tilton box.

I apologize for any confusion.

Len,

I am sending you an e-mail. Our 0200786 is the VD conversion for the single disc 7.25 or single disc 5.5. For the Honda fit , we will need to replace the 44 mm bearing and fit it with a wide radius for the larger spring on the stock clutch....You will still need to double check clearance between fingers and bearing ...... .150/.250. And reset the pedal stop.

The unit Mike has is a stock VD assembly with a Saab bearing.

I thought the Honda VD kit came with the new release bearing?

[LenFC11]

i thought so also. does not.

It's listed in the parts price list.

Its listed in the parts list as Clutch Release Bearing in all three kits. It is just that, the bearing and the adapter to use the slave that they had in their conversion mule, but not the slave cylinder itself. If you look further down in the price list is says exactly what is included: bearing, bearing spacer, o-ring, SHCS & washers (page 7, listed for each kit).

I think that has been their approach since the display model at the 40th, IIRC. It did turn into a bit of a conundrum on the DB6s, since we all had slaves machined differently when we converted to FF, so the spacer provided was good for only one car...would have been less aggro for us if they had just included the slave from new and made a spacer for an unmolested slave, but thats the cost of early adoption, IMO.

swap it over to a tilton, that is of course unless you like splitting the car regularly. The stock slave cylinder uses 2 rubber o rings and they aren't terribly robust. They wear a bit and leak and you've got nothing. When I ran a 99 with a stock slave I ended up changing the damn o-rings a few times a season and I ALWAYS had a few of them in a spares bit at the track.

So back to my original question. Why is it necessary for Taylor to replace the bearing when one was supposed to come with the kit? They need to send the slave without the the release bearing.

What probably happened when Honda was designing the kit was that Brenner's car had the updated Taylor slave cylinder. Honda not knowing it was an update thought all VD's were like that and engineered the kit for that specific slave cylinder.

this is exactly it. except they knew it was the updated tilton unit, they said everyone converts.. while i agree most do, my last car had the upgraded unit, but i know of at least a few cars that have not. i think they should have desinged an adapter for both and given end user a choice. or supply the needed parts in the kit. my build came to a screaching halt

[LenFC11]

im waiting on taylor to find out when they will have avilable.. in the mean time can anyone confirm if either of these will work..
