B10 S/G Belt Again

Recommended Posts


Have what should be the right belt for my B10 (1607323) for the S/G. Went to put it on and it's a solid 2" short.

Put the same belt on my B110 and it juuuust makes it with the S/G rolled tight to the block. The B10 engine is a 243431, but is a 74 code. Have a second issue with it. Engine base has the oil fill in the block and not the base, so my grill shroud won't fit.

I can pick up the correct base for $25 off of eBay, or should I try to find the right engine? Never going to be a show machine and engine seems good otherwise. This belt thing has me frustrated though. Everything seems to be right, but the belt no worky. Looks short on the B110 too, but it'll at least work.B110Guy

I have just the opposite problem. Just got a new belt from ebay and it's just a tad to long, got the S/G adjusted as far as it will go with the current bracket and it slips trying to turn over the engine.

The pictures lead me to believe the motor is not the original motor. If you are not worried about original motor than I would suggest running to tractor supply or your belt source and find one that fits.

I have done that in the past.

Update. Took a way too long belt to get some measurements. Measured right at 3", so I tried one last time. Got to on, but the S/G id nearly at the tight end of the range. I can live with that. Wish I'd have tried one last time yesterday, I could have mowed the lawn.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
