Hardware re-use

[GWGAllisfan 159]

How much of the hardware (bolts, Etc) would you re-use when re-assembling? I was wondering if it would be necessary to replace the transmission to Side plate bolts and the BGB-Frame bolts. What came out looks good, but I just wasn't sure.

Randy, When I re-did the 713S that I brought to Spring Fling last year, I only replaced the bolts that were damaged or missing. If the bolt looks fine and the threads are not damaged, I see no reason to replace it.

If it looks like new coming out, you should be OK, just make sure threads are clean and lubed on the bolt and receptacle threads cleaned only to get the correct torque. The receptable can be a blind hole or a thru nut. The blind hole needs to be dry as it can be broken by filling it up with a lube and then running a bolt in the hole. I use a compound sold by Briggs and Stratton .

I only replace bolts that don't look good, hasn't bit me yet and you all my tractors don't go too shows, they work.

I sometimes use a wire wheel to remove rust. If the threads are rough, I will chase them with a tap and die kit. JH

Thanks guys! Most of these bolts look pretty good, just greasy and dirty. I'm trying to do this on the cheap so I'll just clean them and re-use them. I was surprised to not find Grade markings on the side plate to Transmission bolts, though.

Randy, If you decide to lube the bolts as BLT said, be sure to put the lube only on the bolt when it is feeding into a blind hole. If the lube is on the bolt, it will push the excess to the outside where it can be wiped off. If the lube is put in the hole, then it can be pushed into the hole by the bolt and will act like a hydraulic piston. The bolt will tighten up against the grease, and either come loose later because the compressed grease is trying to push the bolt back out of the hole, or during the tightening, you will strip the threads while trying to get the bolt to seat solidly. When dealing with blind hole, use the lubricant sparingly.
