Did H34's come with a hand crank for the 3 cyl. diesel? Has anyone used a hank crank to start? Where did you get crank? Anyone have a picture of such a hand crank? Thanks for your help!

I'll Check

I also have H34 and have been wondering about hand crank. I have Parts Catalog for 3GMF and will check to see if available. If so I will post part number and cost.

hand crank

There is a cap on the engine covering the end of the cam shaft. Under this cover is the attachment point for the crank. I believe the crank comes with a permenant replacement cover so that the existing does not have to be removed when you want to crank. The crank itself is about 6" long. God help you if you ever have to use it. The attachment point is directly behind the alternator belt and you have to push the belt to the side to insert the crank. When the engine starts (if it starts), watch out. The procedure is to decompress the engine, get the flywheel spinnning, advance the throttle and drop the decompression levers. Sounds simple in theory. 1. Even if you had all the room in the world and a square and firm place to stand in a comfortable position, you can't get that motor to a starting rpm. 2. If you get it to a starting rpm and drop the hammers, you'll stop it dead. You have to drop them one at a time while nursing the throttle.

Picture

I have one I can photo tonight and post in the photo forum. I agree about trying to start one. I have in warm weather and warm engine ( 2GM ). Haven't attempted the 3 cyl. that's why I have "Boat US towing etc." I guess I'll call for a jump before I break an arm. Cranking one is like cranking the old Model T.

I have one

I used mine once when a bad connection prevented adequate juice being delivered to the starter. The crank got the engine going by assisting the starter in these circumstances. I don't recommend it for general use for reasons others have indicated. But I am glad I have mine! I got it (as well as the pin that goes thru the shaft) from Mack Boring. You'll find them on the yanmar web page of distributors. They have the parts list and can help you. If you like, I can dig out the informatin though.
