Perkins 4 Cylinder diesel model no 4107 or 4108..

<< < (4/6) > >>

tom osselton:
You could rig up a kickstart.

vtsteam:
Nope, you need to get the revs up before pulling the valve block on this diesel, and with winter thick oil forget it.

I want a starter motor.  :drool:

mattinker:
Some motorcycle starter motors use a ratchet system like a bicycle free wheel. Maybe there is something allong those lines you could use.

Regards Matthew.

vtsteam:
You'd need a full bicycle with gears you could shift up the gears from low low to about 60 engine rpm under compression release, then some means of  engaging the fuel rack, then pulling the compression release, then somehow totally disengaging mechanically. You'd then have to start the whole procedure again if it didn't kick over, because it WILL come to a dead stop in 2 revolutions after compression. If not 1.

Or.....pressing a button until it starts.

Hmmmm, lemme think about this......  :scratch:

Uh, I think I want Plan B.

I know it's hard to tell without trying it and being here, but for reference  It's 700 pounds has a 6 inch bore (I think) and I'm pretty sure that with the compression not released I could stand on the hand crank and not budge it past TDC. I've been living with this brute for 5 years (the photo was when it was new). We're both 5 years older, and know each other's bad habits well.

I don't think I made myself clear. The motorcycle starter on my K100 BMW uses a ratchet system so that the starter is never disengaged. You have a decompresser, spin the engine up to speed with the starter motor, you drop the decompression lever, engine starts, you stop the starter, the starter drive idles without disengaging. Probably, the easiest way to couple the starter to the crank would be a chain. It's an idea!
