QA42A on a 1250

[crash-harris]

Brand new to the forum and still not too experienced with small engines/equipment, but have been a mechanic for awhile (mostly light duty trucks).

I have a QA42A blower that came with my 1250 and I just put it back on today since we may be getting more snow/ice and both of my trucks are inop. Driveway is gravel and I would rather not use the blade since I'm rather light and have no wheel weights/chains.

I have a few questions for you folks.

1. What is the proper belt size for my combo, 30"?

2. The bigger problem. I noticed when I tried to fit the belt that came with it (seems too narrow and too small) that the pulleys are WAY misaligned. The pulley on my unit is a stamped pulley but has the correct collar with set screws. One was already backed most of the way out, the other was rusted and tightened down. Some PB blaster and a allen bit with a 1/4" wrenchmade quick work of that, but the pulley is stuck fast. I'd hate to have to pull the blower back off (garage floor and driveway are #4 gravel). Will a puller work to get the stamped pulley off? It doesn't look like I would have enough room on the shaft even if I did get it free, so can the pulley be turned around with the collar/set screws facing the blower?

3. Are these collars keyed? There looks to be a key wedged in the blower side of the collar.

4. I have a lead on a cast iron pulley on ebay, should I go ahead and get it? I got laid off back in November so I'm trying to do this with no money spent (for now) if I can. I also got hit by a reckless driver in November so I'm gathering body parts to replace the truck's entire front clip and half of the decrepit fuel system. Diesel parts aren't cheap Plus there's all the vehicle/house insurance/tax coming up on top of paying out for a wedding.

Any help is appreciated!

First, welcome to OCC.....

You know the ole saying, a picture(s) is worth a thousand words.

crash-harris, welcome to OCC. I bought the same model thrower last summer and have it on a 1650. It came with one of these hubs and solid steel pulley;

The large hub has a key way and has lots of clamping area on the shaft. When I got the thrower it came with a B series belt, which I believe is 5/8”. Now I thought the quietlines used a ½” belt, but… the supplied belt seemed to fit well in both pulleys except it was to long. I asked the guy at the belt store for a 30” belt and he gave me a Gates B29 (said it was 30”). Used it yesterday and it worked well.

So, I would say defiantly no stamped pulleys. You need some weight and or at least some chains. I think you could plow better with the front blade vs having the weight of the thrower on the front end with no chains or weight.

Good luck

Welcome to OCC

2 & 4) If you can get the stamped pulley off without distorting it, it could be used. Maybe try tapping it in a little bit so you can clean the shaft for easier removal. KROIL is a better penetrant than PB Blaster but a homemade mix of 50/50 acetone & ATF works just as good.
A cast iron pulley is a much better choice.

3) Yes, uses a key

That pulley looks more stout than mine. Does this forum allow HTML or IMG code photo embedding? I'll snap a few tomorrow. I use photobucket for hosting.

On a side note, I also have a 149 that I just got running late last year, only needed new points (plan to sell it with the other blade and the 2 older decks) and a 1200. The 1200 was my great grandmother's. She rode the clutch a lot so it's been replaced multiple times (last time the flex hub had to replaced as well), but rings let about a quart of oil blow by (no smoke!) and broke the rod. Eventually it'll get a 6 pin clutch and a creeper gear for garden and snow detail.

Yes, the standard [img] tags work. You can also put the link in the "insert image" mountain ----> above the block where the words go in the reply edit

I'll use the attachment on the reply editor. Photobucket sizes my IMG codes to enormous proportions

Pics will be uploaded tomorrow when it's light out (not even power in my garage, it thinks it's a pole barn).

Testing a pic of the data plate on the blower.

In the PhotoBucket editor, you can resize the pictures

The belt is actually 15/32" X 30".
