Bearing Block for the gear drive steering 520H

Haven't  had to make one yet but I thought I was going have to.The zerk was missing on one of mine and the casting is real thin.There were no threads to put a new one in.I was puzzled until I realized that the zerk on this part is pressed in.Your new part looks great.If your brother is like most machinists, to him it is a simple part, that most will marvel at.Nice work! Luck,JAinVA

There were some blocks that the grease zerk was never even drilled out. Don't know if it was by design or a batch of blocks got past quality control.

I would think that's a mistake, cause you would want a little in there a time or 2.

I would want that new block to be drilled out and a brass bushing installed.

Better to wear that than the steering shaft itself.

 

Other than that it looks great.

I made one up myself to replace a broken one.

I'll second that Cleat,  the cast usually wore first because of the softer material, a bronze bush would wear like the cast making it more replaceable down the road and save some on wear on the shaft.

Well that makes a lot of since, I wish I would have thought of that I'll check if we can still do that. I really rather have an original cast piece but oh well.

I don't see why not, enlarge hole to 7/8" and press in a  7/8odx 3/4id oil lite bush. Drill a 1/8" hole down thru the bush for the grease.

Side would be nice but the mounting bolts are there.

Just leave the corners square.

Wear on the shaft is a definite concern if you run steel to steel.If you plan on putting a bronze bushing in the support block it will help.One down side is that the bronze bushing might allow grit to become imbedded and accelerate shaft wear.Since the block will need to be bored it may be better to make the bronze bushing a press fit on the shaft and bore the block for a slip fit for the bushing.This would eliminate shaft wear and the block would become the sacrificial part.Just a thought.Luck,JAinVa
