Autohelm pump leak

fryedaze · Nov 18, 2014

I have a very small leak on my Type 2 hydraulic autohelm pump. It requires a system add about every 300 hours of operation. Has anyone rebuilt one of these pumps? I cant find any information on repair parts. A new pump is about $900. Re build should be easy if I could find parts. The leak is somewhere on the underside, not the connections. Thanks for the help.

Don't mess with it. We live in a throw away world. Buy a new one.

I may have to do that. I have a Type 2 pump. They are $300 more than the type 1 you posted. Type 2 is a larher volume pp. The pump has to be simple to rebuild.

Find your local hydraulic repair shop. But, if it is leaking around the bottom most likely that is a shaft seal and running down. Shaft seals are easy but often the shaft will have a groove in it from the seal in which case it needs a shaft. On a small pumps like that the cost of a new shaft, new seal and other new parts will probably exceed the price of a new pump.

No reason not to get the local hydraulic shop to take a look and advise before throwing away, surely?

Repair

Well I did a lot of searching and came up empty on parts, drawings or any info on the pump. I ordered a new one and then tore down the old one for repair so I will have a spare. Turns out repairing any leaks would be pretty easy. The shaft oil seal is a $3.95 part. Here are some pictures if interested.
