Toro 1028 Powershift breaking the drive chain

[mikekot3 92]

I have a Toro Powershift 1028 that the wheel drive chain is too loose and breaks the drive chain. I have replaced the chain and master link already hoping it was stretched out. The sprockets look okay but I plan to replace them anyway. Is there an adjustment to move the engine away from the transaxle so the chain is more tight?
Is there a service manual available?
Please advise,

Looks like there are 46 different models.

What is the model number and serial number?

don't forget you can buy half-links, find out what pitch and size the chain is and remove a whole link to put the half link in it's place.

I bought the chain and master link from the local Toro dealer. I have not seen half links at the dealer or at the hardware store only full master links.
I will look up the model and serial number tonight.

there's plenty on the online auction site, you won't need a master link as the half link will probably have a split pin to hold in the pin. (some might not though)

My snow blower model is 38560 and the serial number is 210000336 with a 10 hp techumseh engine.
Is there a service manual available here?

Thank you GWest for the service manual. I appreciate it.

Noticed this AM that 3/4 of the file has disappeared likely because it was too large.
Split it into 2 parts so will see if it sticks.

Sorry about that.

Where do I PRY to adjust the slack out of the wheel drive chain the manual do not specify once the pivot bolts are loosened?

[mikekot3 92]

I was able to take out as much slack in the chain as possible although I think I may need to shorten the chain some more. Put the shifter in second gear and have some one hold it there.To adjust the drive chain loosen the gold anodized pivot bolt near the tires and loosen the bolt in the slotted adjustment hole. Turn off the fuel shutoff and take a walmart type plastic bag on the threads of the fuel cap and screw it tight to prevent fuel spillage. Put the snow blower up in its service position on the auger housing face. Push on the black painted transmission bracket that holds the aluminum transmission housing with a pry bar or large screw driver inwards to the middle of the housing. Then tighten the pivot and adjustment slot bolts there are four total. Once that is done and adjust the external transmission linkage belcrank at the transmission end. Remove the nylock nut and loosen Jamb nut and shorten or lengthen as needed. Then reassemble and test the operation of the shifter and power shift for proper operation. It took me several times of shortening and lengthening the threads to get it correct.

 

Anyone know what size chain that is used so I know what I need to buy new master link when I shorten it?

Take a rule or tape and measure from center link to center link If it measures 3/8" it's 3/8" pitch or # 35 chain. If it measures 1/2" it's 1/2" pitch or # 40 or # 41. # 40 is a a bit wider and a heavier duty chain then #41. The roller width of #41 is 1/4" and the roller width of #40 is 5/16".

Hello Don1977,

Thank you for your helpful feedback on roller chain. If I need to shorten the chain do I use a tool like this? http://www.grainger.com/product/TSUBAKI-Detacher-1A911?s_pp=false&picUrl=//static.grainger.com/rp/s/is/image/Grainger/1A911_AS01?$smthumb$

I found a chain breaker on the auction site last year for a go-kart that was cheaper. One of the snowblower forums had your model mentioned with a slack chain and to adjust the trans position -  not to adjust the length of the chain.
