1541 hydro oil fill question

[gkingbing]

While attempting to fill the hydro fluid both with a funnel then tried the electric pump the small fill tube burps and blows fluid up and it eventually ends up on the garage floor. There must be a way to accomplish filling without getting a lot of fluid all over the floor and I would appreciate any tips from you experienced folks. Thanks

Use a small funnel and fill very slow,
I hate changing fluid in any of the Cyclops, as it is such a slow process to refill.

You can buy a funnel like this but I just insert a rubber tube down the center of the funnel.
It has to be small enough to let the liquid run past it and large enough to let the air in the case escape.

Thanks for the tips....that worked....BUT, I had a small plastic tube jammed into the funnel that would fit into the fluid fill and when I pulled the funnel out the tube went into the transmission.....Not a good situation....PITA!!!!

Late machines have a vent on the top of the case. On older machines when I have access to the top of the case at the rear I drill and tap a hole for a vent. Pics of both the early style with my vent and the late factory vent.

i use a piece of metal 3/16" brake line bent so it can't fall into the transmission
