tension on mower spring

Recommended Posts

landlord2110

mower deck 1690252 has spring 2154369sm that puts tension on belt underneath deck cover. being 40 plus years old, do you guys think it should be replaced? there is hardly no tension on the belt & I get a lot of rollover grass thats not cut.

I doubt it is the spring. More than likely the pivot does not move freely enough. I would take it off and clean it all up and lube, make sure it moves nice and easy, and also make sure you have the correct length belt.

A belt too long will not have proper tension

Could very well be exactly as stated above. Frozen pivot and/or worn belt. If the belt isn't worn down, they do not take a lot of tension to preform properly. They shouldn't be sloppy, but they don't need to be like a piano string either.:o)

frozen pivot is what I found on one of mine when the belt went needed new belt but the pivot freed up without much trouble.

My advice would be to clean it up and make sure the pivot is free and lubricated. Also, a 40 year old spring can be dangerous. I went to take mine off and paid the price with a pretty good black and blue thumb when it decided to give way. Just a word of caution when you go to remove the spring or put it back on. Rust never sleeps!

I know a man who has had a glass eye since he was 23 years old in 1960 because of a spring breaking. (I admit that I often fail to follow my own advice but close my eyes or look away a little when getting a spring stretched out).

You shouldn't have to have much tension on the spring, I pull

mine on with pair of pliers and very little effort.

It just needs to take up the slack and keep the belt snug.

I rarely tension a spring directly, especially when a long belt is involved such as the arbor drive belt.

For the deck arbor belt, my method is to install the spring, route the belt, then at the left side of the deck (away from the spring), pull the belt and use the arbor pulley to tension the spring.

Does anyone here know if you can convert the old style deck without a spring to the spring version?

I'd like to see the routing for that new installation, myself. I bought the parts, but it looks like the idler will run on the wrong side of the belt and not tension anything

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
