I'm currently re-assembling my Rotax 503 and will need a propeller crush plate and correct bolts to fit my prop. Anyone one have such items they can spare or are willing to sell at the lowest price possible. I'm not a tight ass but cash is in short supply at the moment. My engine has a type 'B' gear-box fitted so the bolt pcd is 75 mm. PM me if you can help. Cheers.

Edit, deleted nuts, flange is tapped so not needed.

I'm pretty sure I'll have a spare R503 crush plate up at the hangar but won't be on site till the w/end. Will check with you then and if I have and you still need I'll get in the post to you. cheers

Riley, just found out that I have a type A gearbox with adapter plate, not type B I hope the crush plates are the same. Cheers.
Found the crush plate but don't have an 'A' box to compare flange specs. Plate dimensions are: PCD of 6ea X 9mm ID bolt holes is 37.5mm and PCD for 6ea X 6.7mm is the same. Od of crush plate is 100mm. I'd reckon the g/box prop flange will be the same for 447 thr 503 range but will await your confirmation that this one will fit before putting it in a postal bag. Send us your mailing address with your confirmation/denial. cheers bob

Crush plate arrived safely and is the right one. Many thanks Bob. Can't do any work at the moment due to pulling a back muscle by reaching and lifting muffler with one hand. Should have learnt by now not to reach....and lift.
