New replacement grill on my 108 :)
 

Wow, I'm really liking this ABS board! I lost one of those silly springs that hold on the grill :bash2: Every time I thought I had that thing twisted in correctly I found myself wrong. First time I was able to find both springs in the driveway but the second time I was not so lucky and only found one. I'll order another one but in the meantime I made a replacement grill with this ABS board and really like how it came out!

hopefully that has holes in it or the motor will overheat.
thats why the oem one has them.

I was thinking about that so I'll only be using it for this fall and winter. Once it warms up I think you're right and this will need to go. I should have that silly spring by then :bash2:

What is wrong with the original? I can't see from the pictures, broke?
I would do as Lew suggested, get some holes in your new one.:biggrin2:

The original is fine but I lost one of those springs that hold it on. Since I had some of this board around I thought I might give it a shot.

Exactly what I was thinking. Shouldn't matter the season the engine needs to vent IMO.

:Morning: Either get rid of that ABS grill or put some holes in. Better yet, put the original back in and use zip ties until you get the correct spring. :American Flag 1:

So just for conversation sake I'd like to explore this a little more. At most this tractor is hitting a whopping 5 maybe 6 miles an hour. So at that speed there is very little breeze coming in on the engine to cool it down. There also is no radiator or fan behind the grill that would need vents for pulling in or blowing air out. Also, since this is not a QL, there are no side panels covering the engine. All this being said are the vent holes in the grill more for hot air to escape off the engine and the open sides are not enough? Again, this is not a confrontational response so please do not just respond with the "it's your tractor do what you want" template. I'm really asking to understand this. I've also seen puller tractors with the sides totally covered but those tractors are normally not running for a long time so maybe that's why they can do this?

The cooling air is ducted in through the flywheel, up around the cylinder, then out through the front. The grill without holes disrupts the flow, so yes it is going to get warmer than normal. It's not airtight, so yes some of the heat will escape, just not as quickly as they designed it too. Not going to kill it right away, but will definitely cause it to age prematurely, like heavy drinking. :beer2:

Wow totally didn't realize this and glad I asked. I had to read your post twice because I was going to say that the flywheel is on the other side of the engine and did not know how this had any play here. I can totally see how the flywheel with it's fins could be pulling air in but did not think about the airs escape. So in this design the air is being pulled in from the back of the engine and pushed over the cylinder then out the front, hum never new that. Well that makes more sense to me now and thanks :biggrin2:
