BGB Play

Recommended Posts

MPH
Took the 3314 out side tonight and gave it hotwater bath after it soaked in foamy clean engine bright for about 15 min. hard to see what I was doing as the 160 degree water really steams at -15. but, it's clean enough to want to work on now. Checking play in the BGB and with the use of 2 carpenter tools I figured it for about 11 degrees of play. 4 1/4 inch pulley move about 1/2 inch. Seems a little excessive to me. Looking for opinions on what you all think. thanks

I would say that's to much. If I needed to use the tractor I would leave it in but being your going over it and have others I would take it out and apart to see what's up, or at least remove the rear plate to see if it's keyway slop or worn gears/adjustment. JMHO.

Maynard, Correct me if I'm wrong but I thought you shimmed that flush with the outside of the case to hold the bearing in when the side plate was bolted on. It has no effect on the adjustment of the gears at all. If you were to remove the drive pulley you can actually pull the shaft out the PTO side. I always add a shim or two between the bearing and gear (J-K)or(T-X) if a little loose.

The retaining ring (AN) that seats right at the spot the letter p points to, will allow the shaft to move out on the side with the hydro pulley the driven gear has a relief in the face for this ring if it gets to sloppy with age or wear it will bounce the ring out of the groove and allow the shaft to move in and out.

Thanks for the motivation to do it right guys. Gonna be sidetracked with chasing greenbacks this week as a guy came out at 8:30 am last week and talked me into doing a commerical tile job for him. UI is nice but don't pay well. Your all right though, don't have need for the tractor right now so may as well check it out right. If the Vickers works good, it'll be my mowing tractor next summer.

Shim as required, to adjust back lash. you do not need shims to hold the seal in, the side plate will do that it self. The shims put presure on the seal which in turn puts preasure on the ball bearing then the driven gear. Read the large frame repair manual section 5 page 5 bevel gear drive. 4. Spin the driver shaft (C, Figure 5) several revolutions in both directions while applying light braking pressure to the driven shaft (B, Figure 5). Repeat this procedure, spinning the driven shaft. Note for future attention any noticeable binding, roughness, unevenness in the motion, or excessive backlash (lost motion) between the gears. The true backlash can only be checked once the shims and side plates are installed.

      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!😁
