jd crawler HLR adjustment

Post by boccop » Thu Feb 11, 2021 5:42 am

My crawler "creeps" a little when I shift into neutral...have to wiggle it to get neutral. My book doesn't show the adjustment for this model. It has a threaded rod "turnbuckle?" that we've freed up but don't know the proper way to adjust it. The machine is a plain old 450 crawler/loader from late 60's or early 70's. Anybody able to shed some light? Thanks

Having to wiggle it to find neutral sounds like wear/play in the linkage. Check all pins and joints. The turnbuckle would be the adjustment point, if it is the only adjustable place in the linkage. What book do you have?

I don't have that one to look through. Strange, but not uncommon there is no info, or it may be buried in a section on something other than transmission overhaul. It appears the early 450Bs had that same shifter set up. There is some info about adjusting both shifters in the 450B manual TM1033. There is a copy of that manual you can access on line to see the adjustment info. Here is a link. https://archive.org/details/John_Deere_ ... ual_TM1033

In the TM1033 manual look at section 50-15-14 for the HLR shifter adjustment. If the yokes, pins, bushings, etc. are worn, you may need to repair those first to get the adjustment correct. HTH

MY 450c doing same. Took HLR and gear shift completely apart, replaced turnbuckle pins and roll pins. All were slightly worn. Worse wear point was the HLR linkage at the transmission. Took the next larger size pin (slight grinding needed to fit in the trans linkage). Then hammered the bottom yoke (this was where the most slack was) to fit the oversized pin. All is tight and shifts as it should.
