Mark VII

Thanks JPG! I used elevator bolts from Lowes. I figured it would be a better rest than the normal hex head. I've heard about the issues with the drive belt. I've also seen posts where the Mark V belts will work all around. I take it this isn't true? Ebay has a seller that's saying they have Mark VII poly belts new for sale but I haven't checked any further on the drive belt. I'd like to at least get the poly belt replaced while the bearings are out, the drive belt can be changed easier than the poly belt.

He sells the same belt for either one! I conversed with him, and the demand for the MVII belt is not likely enough to justify his up front costs. I assume his belts are good.

The motor/idler shaft is 2" further apart in the MVII, so a M5/V motor belt is 4" too short.

A while back SS was providing a 'current' belt version and that led to much discontent here.

I do not understand why the belt manufacturers state the belts are .53" wide, when they are actually less than 1/2". A lot of metric/imperial converting/rounding/truncating(hand waving) going on with no regard for reality.

I didn't realize the Mark VII belt was 13 ribs to the 9 on the Mark V's. I assume that they would both work relatively the same as long as the length is the same. It'd be nice to find a 13 rib one though. I did check the SS site and they're at $22.80 not including shipping. The Ebay seller is asking $24.95 with free shipping. I guess it's a toss up. I work for an ExxonMobil distributor and deal with a lot of auto parts stores. I guess I'm going to have to work my contacts to try to find a drive belt that works.

Robb

I am glad the little lever plate solved your problem. I have a complete lever, plate and all that was given to me available, as well as the blower assembly less the fan ( I sold mine on eBay). if you can use any of these pieces, let me know. The outlet housing on the blower has a piece broken off but could be repaired.

I also have the motor if someone can use it. The wire insulation was gone and I replaced them all the way to the stator as best as I could. If someone can use it. It's heavy so I will not eat the shipping

I'm just glad we have two Mark VII gurus on the belt search. Keep posting.
