Greasing my Max Prop

[demonboy]

Do I have to disassemble my Max Prop in order to grease it or can I undo an allen key and squirt some grease in?

I have come across this manual here:

3-bladed Max Prop Manual Here

And some videos too:

Videos here


However I'm a little unclear. The video clearly shows two grease holes on the two bladed prop yet my 3-bladed Max Prop doesn't have them. Instead it has a number of different sized Allen key bolts holding the thing together.

It doesn't help that I don't have the original manual because I can't search for the specific user guide.

Can anyone shed any light on this?

When I had one, you had to remove a bolt and put a grease nipple in. Then squirt in the grease and stick the bolt back in. Darglow Engineering are very helpful and I'm sure they can give you the info you need.

I have had two 3 bladed MaxProp's. Both had two small grub screws on one of the spinners. Remove grub screw and replace with grease nipple. Inject grease. Replace grub screw. Repeat for other grub screw.

There are two alan headed grub screws adjacent to each other on one side of the spinner, remove one and replace with a grease nipple, grease and then remove nipple and replace grub screw, repeat with the second one.

This is still confusing because you describe 'on one side of the spinner'. On my spinner I have three allen bolts either side, kind of like this if you are looking down from above where the top is the forward end of the prop and the bottom is where the blades sit:

Two are larger bolts and the third bolt, at the front end of the prop, is a smaller allen bolt. It doesn't make sense that these are the grease bolts because I was expecting a forward and aft grease hole, not either side of each other.

Please help, I only have two days left on the hard!

OK, we decided to take it apart in the end. Clearly this is an early maxprop model so there are no grease points and it may only be greased by taking it apart.

Fortunately there was enough grease in there already so I didn't have to dismantle the whole thing. Even so, fancy designing something that comes with instructions that say grease annually, which requires you to completely dismantle the prop!

I had to grease one a few years ago - it had seized up due to lack of maintenance. Attached to the handbook was a sealed polybag containing an allen key and a grease nipple (polybag had never been opened!) Can't remember seeing any other bolts on the boss - tempus fugit - but the size of the key made it obvious which three small small allen bolts you had to remove in order to attach the nipple. It was a suprisingly small nipple for such a big prop. If there is a big size differential in the bolts that you can see, go for the smallest.
