Default SDCE Tensioner and Belt Slip

I have the SDCE LS1 tensioner and am getting belt slippage. Dust everywhere. 14lbs down to 9-10lbs.

Anyone experience this? If so, what did you do? Thanks

Never had any belt slip with my SDCE tensioner. I have mine set up with the prochager pully down as far as it will go with out pushing the belt in to the stand off nuts then I set the spring tensioner tight. Did you get the litte tool from SDCE to set their tensioner ? Also get a new bet on there before you try to tighten up the 2 tensioners.

It is a pain in the *** to set untill you have done it a few times. I will usually try to have some one help me when I do it, one guy holding tight on the 1/2" wrench for the tool and the other tighting up the 3/4" wrench in the center of the tensioner spring.

Can you tighten it with the belt on or do you have to take it off and preload it again.

I appreciate the help. My buddy's was way out and mine was against the stopper that sticks up.

I set the tension with the belt off and then use the nut on the pulley bolt to spring the tensioner over and rap the belt on, just like you would with the serpentine belt

Great advice

The aster bracket is the SDCE with the small pully added to the J bracket.

Never had any problems with the 3 different SDCE set ups I ran at max impeller speeds, and even a little over. I have logged 19# with a D1SC and the SDCE

Can you stick to the subject? I don't care about what youre trying to endorse or sell.

Post somewhere else. Are you trying to proposition me ***? Ramada Inn. Rough guy.

Well the only time I had belt slip with the SDCE was when it was adjusted wrong. And its a fine line too. I ran the Aster bracket as well and while its a nicer designed peice, I can't say that it worked any better. I liked both, but there is absolutely nothing wrong with the SDCE set up and its a little simpler to put belts on etc... I ran 28# on the SDCE bracket F1R on a 346. But with the tentioner just a tad bit loose it would only run half that lol! I like to adjust them. Then drive them around just a bit, not real hard. Bring it back and re-adjust it a tad bit tighter etc... GL! Hope it helps you.

Check belt alignment. It needs to be pretty close (within a millimeter or so) to keep belt slip to a minimum.
