Deduduction/write off or neither.

Change it and gone, so much less expensive. Besides, why worry about the write off? You only get to effectively write off your tax rate, not 100% of the service call -it is not a dollar for dollar deduction from your income tax. Even if it was my time is much more valuable than a few hundred dollar tax savings.

 

Depending which engine, we'll use my ISX, the two big tensioners are $320 each, with a discount me picking them up at Freightliner. The two smaller ones are about $200 each.

The serpentine belt is like $38.

So like $1200 for wrench to do the whole kit and caboodle in about an hour.

If the big tensioner grenades on the road, it's gonna take the belt along with it, probably in the neighborhood of $1200 to $1400 to fix that one and the belt.

I keep the old belt in my truck. Inside is cracking, but it's for emergencies.

As has been mentioned, this is a pretrip kind of thing.

When your tensioners are squeaking, squeaking, squeaking, guess what?

Take a trip and look in the mirror after you read this.

 

Same here but not fun working on a hot engine..

 

Anytime you can lower operating cost the more money in your pocket . Yea your paying a tax on that money but it a % of what you made. Downtime cost you revenue thats not a write off instead its no food on the table .My operating cost are 1.32mi i lowered it this yr to 1.09 by doing my own work belts, pm, some bolt on items. My pms cost 120.00 for oil change . I see a dry parking lot i get the grease gun out. I have a Glider truck so things are easy to wrench on to that helps

 

If I have the belt I will put it on. IWX is the only company I have driven for that gave us a spare belt and the tools in a emergency box under the sleeper. Had to replace a broken belt on a Columbia/CAT in Newberry Springs CA in the summer of 2003 was glad to have it.

 

Trying before crying. But I really got a lot to learn.
Crying is not going to help. When you changed the belt should’ve changed the tensioner. Signs of bad tensioner (include but not limited to) that I know is odd noise (sometimes very hard to tell) or belt slipping to the side (sometimes barely visible).
