Re: Oil leak vs Grease leak MT prop ?
I'm having a similar leak on my Hartzell two bladed metal (non-powerflow) prop, but mine is leaking from the prop hub. Can anyone help with an exploded parts view, I'm curious what all the parts look like.

Re: Oil leak vs Grease leak MT prop ?
Is the o-ring replacement part of the prop over-haul or an easy job of R&R of prop and replace the O-ring?
Just want to be sure and don't want to spend money on over-haul unless necessary.
Thanks

Pulling on a blade isn't going to shift that at all. However, like any seal, it could develop a leak as the rubber compound ages and shrinks. It is easy to replace that O-ring, but the prop has to come off.

Re: Oil leak vs Grease leak MT prop ?
It does come with the prop, but I would think it would be simple to get a replacement. Check with MT-USA or a shop that does MT work. Since it fits a Lycoming crankshaft, it might not even be a MT-specific part.

You can buy the O-ring from MT in DeLand, FL. It is PN: C-048-B (Flange O-ring). They cost about $2.50 when I bought them (plus shipping).

Re: Oil leak vs Grease leak MT prop ?
So, Get the O-ring replaced first before proceed to next step of prop over-haul?Steve wrote:You can buy the O-ring from MT in DeLand, FL. It is PN: C-048-B (Flange O-ring). They cost about $2.50 when I bought them (plus shipping).

Re: Oil leak vs Grease leak MT prop ?
I wasn't suggesting that. What action you take depends on what is leaking and from what location. If it is oil, leaking from the O-ring, then replacing that would be reasonable, since it is easy and cheap. If it is oil from the front seal on the engine, the prop will have to come off, and a new front seal installed (plus a new O-ring on the prop). If it is grease from the blade seals, your prop should go to the prop shop for assessment and possible overhaul).yl472401 wrote: ↑Mon Dec 14, 2020 6:11 pmSo, Get the O-ring replaced first before proceed to next step of prop over-haul?Steve wrote:You can buy the O-ring from MT in DeLand, FL.
