520 vented belt guard

[Wishin4a416 2,191]

Was wondering if anyone had pictures of their handy work and location on the belt guard mod to improve air flow on the rear cylinder. I will do mine in the Spring before mowing season.

Thanks

Required a pencil, a combination square and a step drill bit.

Heres mine

Jack the image I really wanted you to see is this one.I personally believe that shortening the belt guard support does more than the holes.When you look at the thing straight on the bracket covers more of the cooling fins than the belt guard does.JAinVA

Jack, if you look closely at the pic of my guard venting on the thread that Craig pasted, you will see the housing I made to collect the back cyl heat and pump it into the cab.

To give you an idea of the amount of heat this produces,  the cab stays ~40 F warmer that the outside temp.

Heres my version, i bought a stainless steel vent from a marine supply company.

Always liked the venting talk. the best part I like is using the hot air for heating the cab in the winter.
