149 Front Pulley and Lift Help

[Mr Bob]

Have this old 149 that I bought last winter. Used it very little since purchase. Just seen that it had worn the S/G belt badly. S/G pulley and Front Engine pulley seem to be out of alignment. Is it possible to move the front engine pulley away from the engine about 1/8 inch? Would this affect the pto going back on properly? Also had to put a bolt through the inside lift arm to raise and lower the mower deck. I will try to attach photos. Does the lift setup look normal? Thanks in advance for all your help.

The 125 I just bought is out of alignment too. If you don't mind I'm going to pay attention to this thread.

If you remove the two set screws on the pto pulley you can move it forward.
They are located in the holes closest to the pulley.
They are allen head and that is the easy part as the pulley does not move that easy after being on there for 40 years.Use plenty of pb blaster and gently tap the pulley forward.

Here's a picture to go with Lew's description ( I drilled and tapped my pulley to use my homemade puller )

Sockets made for a great bearing puller


I spaced the 5/16" holes for the bolt at 3/8" wider than the bearing diameter. I used two 3/8" drive 1/2" sockets ( correct socket for 5/16" bolts) to grab the bearing. After loosening the eccentric, it comes right off.

Using the puller to pull the pulley off, just drill the pulley with a "F" drill ( .257) and tap the pulley 5/16-18NC.

Looking at your pics, I think you have a spacer behind the pully on the S/G. Try taking the S/G pully off, remove the spacer, then replace the S/G pully. You can check to see if the belt will line up correctly without the spacer before tightening the nut for the pully. If that's not a spacer, then disregard my advice. I don't use the spacer on my S/G.

I have no idea but it might also be possible to pull the S/G pulley off and put back on "inside out".
Maybe there is an offset in the pulley.

It's hard to see in your pics but do you have the PTO bearing on the crank? The bearing should be flush with the end of the crank and the pulley sets up against the back of the bearing. If the S/G pulley is not inline after adjusting the bearing and crank pulley, then the pulley is wrong on the S/G. I had a pulley alignment issue on my 126 that ended up being the crank pulley and bearing being out of position.

I thought they all had a spacer just different thicknesses.
