I have decided to share the build of my 2285 type 4 engine, even though its featured at my homepage. Im doing all the machinework and assembling myself. If anybody need some work done, feel free to contact me, contact information is at my website www.gbot.dkHere are some specs on the engine.. Type 4 case with sleeve inserts for type 1 lifters.. STD 66 crank carefully ballanced with flywheel and clutch.. Ultra light 200 mm flywheel. Kennedy stage 2 pressure plate with superdisk. Flywheel and crank is 5 dowelled along with BAS bolts for strenght. Web 251 cam. straight cut cam gears. STD lightend rods with new bushings and ARP2000 rodbolts. JE 105 mm lightweight pistons. Deutz cylinders reworked to fit the application. 2.0 liter heads with new alubronze seats for 48/40 valves. Heads have been welded up in the spark plug holes and new thread cuts for the plugs 914 style. Chambers have been welded up to make 12,5:1 compression possible. Manifolds have been shortend to reach the right puls. Carbs will be 61 mm terminators. Exhaust 1 7/8 header, homemade. Im throwing up some pictures, feel free to ask questions and throw in some input. More to follow as the progress gets along. Regards, Jakob. |

that is awesome work there!!! hope you dont mind me asking, but i got a flywheel for my type 4 motor, which had been drilled for the extra 5 dowels, but people put me off and said it weakens the end of the crank because of the holes drilled into it removing so much metal, as well as weakening the flywheel itself... so i sent it back and got an undrilled one...  was i told wrong ? maybe i shouldve used it... anyway, nice website too, i need to translate it though, looks real interesting.  |

Thanks for the kind words guys..
Got the deutz cylinders finished today, just need to have them bored now.. What a hell of a job makin them fit, goush..
I know of a guy pumpin out 300 hp on his 3.0 type 4, his flywheel is 5 dowelled as well, and he also uses the BAS bolts.
Merry christmas everybody..
Jakob

I thougt it was Jakob because he also had plans for a 105X66  the camshaft and valves are also the same as Jakob's, so your engine should pull well Jakob |

The Deutz cylinders look the business! Good thing they have more fins then the "originals".
How much cylinder wall thickness did you end up with at the head-side?
Tnx,
Walter

Yeah its a great cylinder I turned them down to 115 outside diameter at the head side, and 108 at the case side, I could had gone bigger on the case side I guess, but would like to be able to use "STD" 105 cylinders if I get problems finding deutz cylinders in the future.. Regards, Jakob |

The Deutz cylinders are very strong . I think they have over 120 mm on the top . We use them for Oxyboxer engines . But it is a lot of work .... Udo |

We used to go through the Deutz tractor dealers parts bin and take ditched ones But thatīs not easy anymore as even Deutz has gone watercooled now. So they are not as easy to come by now as previusly. As said itīs a super strong cylinder, but it takes a lot of work to make them fit a type 4 or a WBX for that matter. T |

It is no problem to get them new and DEUTZ still makes new engines "aircooled" !!! And will build them for the next years ! The need them for special application in some countries. I think it is possible to get the cylinders without pistons , i try to find out next year if someones interested.. |

Nice work Jakob, love the combo.
I've been toying with the idea of 66 x 105 using Deutz cyls as i have most of the parts, should be awesome to see how your engine performs, I'm sure it will be a blast.
Good on ya mate.

nice work.. but is i was you i would put some longer rods in. if you see on a modern bike engine you have big bore short stroke and long rods to slow the piston down so it have the time to suck fuel in.. if you use the standart rods you have a high piston speed and it has not got so lont time to suck in fuel..'
my idea for a screamer, some of the parts is on the shelf..
wbx/oxy case modyfied for type 1 lifters.
destroked dpr crank 66 mm
6,2" pauter alurods
4"cp pistons with high wrist pin.

Wow! Nice work. You guys make me want to consider a type 4 motor in the future. Especially now that you can actually get a lot of parts for them.

Got the valveseats cut 3 angled and measured the combustionchambers, they turned out to be exactly 40cc, A little more than I expected, but I can live with that.. Have started to port the manifolds to match the 61 terminators, it takes time and my hand is still shaking |
