Fitting 40hp and later flywheel on 36hp crank and case?

GüteAndTite

what special flywheel do i need , or what maching/welding needs to be done to mount a 40hp flywheel to a 36hp motor?

i have a very specific reason for doing this- fitting a 61-67 saxomat clutch system to my 58's 36hp motor. the trans, throw out, pressure plate, and clutch disc all will work, as will the flywheel gland nut, but i need to know what to do to the flywheel to fit it up. and no- i dont want to just throw in a 40hp motor

Some of the landspeed guys cut the centers out of the 36 horse flywheel and have them machined and welded into the centers of later model flywheels and spin them at ungodly rpms (for a 36er). Would something like this work for you?

36hp flywheel is about 12.5mm shorter than 40hp when you set them flat side-by-side. Part of it is the length of the flywheel seal collar, part of it is in the main casting. The crank end diameter is smaller diameter, and the the flywheel seal collar is smaller diameter. Crank pins smaller as noted above as well.

Would it be possible to rework a 36hp flywheel to fit the saxomat clutch instead?

Here's some saxomat specific flywheel pics and diagrams- notice in the diagrams the part of the flywheel that bolts to the crank is split from the portion with the ring gear and is bolted to this as well

Referencing Brads suggestion, contact Art Thraen at A.C.E.(Air Cooled Engineering) at the address below to find out if he can duplicate the Blackline Boys flywheel mods with your Saxo-Mat flywheel.

Any thoughts on the modifications needed to fit a Saxomat flywheel to a 30 horse crank though?

Cheers,

Dave

That -used- to be a 1600 flywheel, it now fits 36hp and Porsche. Jose at DPR can weld and remachine the hub center for 36hp either 8 or 4 dowel. The process is just a bit spendy, but it works well.

I'm going to take my 36 horse flywheel along to the engineers who are refurbishing my Saxomat on Friday so we can look at the differences and find a solution. It's been suggested (by someone else in the know) it might be as simple as drilling a couple of holes but that depends how things line up and how much meat is left in the system.

I've also been told you really should consider a later full syncro box for yours as double declutching with a Saxomat is nigh on impossible.

Having said that, you're as stubborn as me so you'll probably find a way of doing it Smile

My original box is long gone so I already have a later early 60s box in place.

We sent our flywheel to Jose at DPR. He has done this for a lot of other people too. He is great to work with and knows what he is talking about. Air cooled engineering did not make our flywheel.
