OutdoorKing Repair Forum Forums Repairs and Maintenance Questions On Ride On Mowers Questions on Rover Ride On Mower Rover 28166 - Engine Pulley Dimensions

Surprise, surprise, surprise.......when contacting MTD (stands for "Much To Do") to order a pulley for a REAL ride on mower, they don't have it in stock. But wait....they MIGHT decide to stock it again.....sometime next year........................maybe.

So, here I am, with a customers machine waiting to go, but no drive idler pulley available....bugger it, I'll make or modify one!
Part # A10510 (sprung drive idler off 28166 etc)
I have dimensions A and C, but need to find "B" and confirm "D" (assume this will be 1/2")

Anyone have one they would be able to measure for me?

Tentimes, you seem to be asking a lot of Outdoorking members when you don't tell them what model of ride-on you are talking about, or show them any pictures of the old part you are trying to replace.

Hi Grumpy,

I've just re-read my original post and note that I included the model number (28166) and also the part number (A10510). As a professional repairer, we rely on part numbers, rather than pics, as the latter is far too ambiguous. Also, I would have found it rather difficult to take a photo of a part I don't have. My apologies if I sound rude, but this is absolutely not my intention.

I know the model number is incomplete, but there is no longer any ID on this machine. The part number is common to versions 2 and 3 of this model designate (and many other models as well). In an attempt to make things absolutely clear, I have now included an IPL image.

Hope this clarifies things.


The part in question is #80 (part # A10510)

Tentimes, I think what Grumpy might have been reffering to would be that when you sprout two part numbers you are alienating probably 95% of the people that come on the forum that do not run off parts listings and model numbers.

Its like I have a blah blah model rancher. Well to me there three types. The old rancher 2, the later 11hp with the 5 speed transaxle and the autodrive. Sure theres great heaps of variatons probably 30 or 40 model numbers, but I cant tell you what part number is what or what model is what configuration.

So to work out if I can help you I would have to search the model you mention and the part number.
More info means you are telling me yes or no if I can help you straight off the bat.

You did that with the pic above but its still not enough.
Going by the pic above that bit looks familiar, could it be a rancher auto drive? that bit in the pic is up in the back shed in a plastic tub.
And if its not and its a similar shaped part on an earlier 5 speed transaxle job there a machine out the front thats up for wrecking shortly (have two here and havent looked under either.)
And theres always a chance that they are the same on both machines. The ranger and the rancher share a lot of parts too. A lot of different mower share a lot of different parts.

So yeah a picture helps me a great deal.
I can spot the difference by the bonnet on the rancher. Its not an exact science but it gets me close.


Cheers, Bob.
