Almost got my Maggie 1900 done on my truck today and realized that the belt is missing from the kit (along with a few other important pieces, ). Does anyone know what the belt number is for the stock pulley? Is it the Gates K061098?

 

Don't know about Gates, But Dayco #5061115 will fit it. It should fit with any pulley.

 

did you purchase this new? If so call, we will send you the parts.

 

EDIT: Belt sizes for the Radix MP112, NOT the TVS

Pulley size -Belt Size -Boost psi.(apx.) - Goodyear# - Gates#
2.75" Pulley = 111.0 " Belt = 9 to 10 psi. - P/N=4061110 - P/N=K061110
2.8" Pulley = 111.0 " Belt = 8.5 to 9 psi - P/N=4061110 - P/N=K061110
2.9" Pulley = 111.5 " Belt = 7.5 to 8 psi. - P/N=4061115 - P/N=K061115
3.0" Pulley = 111.5 " Belt = 7.0-7.5 psi. - P/N=4061115 - P/N=K061115
3.1" Pulley = 112.0 " Belt = ---6--- psi. - P/N=4061120 - P/N=K061120
3.3" Pulley = 112.0 " Belt = 5 to 6.5 psi. - P/N = 4061120 - P/N=K061120

This is for the Radix MP112, hopefully Brian can chime in if it is the same for the TVS. And for belts, I run Gates and most people on the forum have good results with them. The Gatorback's too for grip, but they don't seem to last as long.

This is a 111.5" belt, which might be a little small for the stock pulley. Just look at the last 4 digits of the part # for the size.

 

The 112 and 1900 do not share any drive parts.

 

So that means they have different belt sizes then?

 

exactly what it means

K061098 is the TVS belt and K061120 is the 112 belt.

 

Tricky I will edit my above post so as to not mislead.

 

That Dayco # worked for me with the stock pulley and the current 3.1". I do have the old first (?) design tvs1900 tho with the j-tube. Maybe they took different belts? I've also got the 8-rib tensioner, maybe that makes a difference.

 

Thanks for all the replies, guys. Yes, I bought the kit new. I'll have to go and buy the belt locally, I can't wait for too long to get one. I'll give Magnacharger a call and get the missing parts. So far I've been able to make things work but I'd like to fix it up right. I found both throttle body sensor wires to be too short so I have to extend 11 wires today and mount up the fuel pump.
