    Re: pit

    About 3 1/2 hours.

    In addition to the work you did you should:
    1. Inspect the cushion and replace any worn cushion blocks or supports.
    2. Replace any missing rubber rivots.
    3. Inspect and replace any cracket carpet angles.
    4. Remove, inspect, solvent tank, lubricate, and reinstall the front roller hinges.
    5. Remove and replace the rear roller bearings with freshly repacked bearings.
    6. Replace the front roller with a roller that is lubricated and had repacked bearings.
    7. Install 4 new vibration dampeners on the bounce plate.
    8. Tighten all bounce plate reinforcement bars.
    9. Inspect the bounce plate brackets and reinstall them with grade 8 bolts and stover lock nuts.

      King,

      Item #4 on your check list say's remove the solvent tank.

      Solvent tank?

      I have never seen a solvent tank in a pit.

      Is this something new?

        Re: pit

        Yep, do everything that King said. We replaced all of the pit supports with the newer type. The pit should run for two seasons before it needs attention, if you do a complete rebuild.

          I think he means clean the hinges in a solvent bath...j. I used to spend about 3 hours farting about cleaning everything, but if speed was the key I could change a bounce plate in about 40 minutes all in.j.

              You should also carefully inspect your front and rear roller support brackets.Remove front brackets,clean and lube.Make sure the rear roller bracket,ball door side isnt cracked.We have grinded ours off and bolted on new ones.Just something else to check.

                Re: pit

                If you do everything on King's list, which is exactly what we do, you will get a LOT more than 2 seasons.

                  Good list Jerry, but where does the missing hour and a half go???? lol

                  hand packing front/rear roller bearings is a waste of time, they are less than $4 each. Just use new ones. Also bear in mind that the over all RPM's of a pit is very low. some greese is enough. they dont have to be 'full of high quality'. Its not turning at 2000 RPM like a wheele bearing, and lives are not hanging in the ballance. Run one for 2 days straight, and them pull a rear and feel the bearing. if there is ANY heat, you need greese. I have never found a warm roller bearing unless there was some problem that led to its early demise, and I have never hand packed a new bearing. If it isnt good, I replace it.

                  I suggest going with enviro front roller links and bearing support bushings... Huge time saver.

                  With the stahls spring tool, the removal of the front bearing supports are a piece of cake.

                  I didnt see anyone (may have missed it, in a hurry, trying to move) mention the plows. broken or cracked plows will wreck havoc on pins. Small ones can br replaced fairly cheaply (less than $70) the big ones are pricy, so I suggest welding them.

                      Re: pit

                      In a high lineage house, the pits should be checked out every other year. I can usually can find something wrong in the pit by the time two years rolls along. If you are doing twenty lines a day per lane, the pit should be OK for a few years.

                        <font size="2" face="Verdana, Helvetica, sans-serif">New bearings have plastic cages and do not have the longevity of older bearings.

                        The reason to solvent tank the bearings is to get rid of the dirt in the grease.

                          I have yet to see a plastic roller bearing, but it wouldent surprise me. In Vermont I did front wheel bearings for a friends full size 3/4 ton pannel van. The bearings that he boutght at the ford DEALERSHIP had plastic cages.

                          With thedays technoligy, it apperantly isnt a bad thing.

                          Greese is usd to inhibit friction. Plastic, inherantly, produces less friction than metal does. and, once again, they are spining at roughtly.....120 RPM. a plastic one could probably run completly dry for a solid year before failing.

                          I knew a guy that would pull seals off of a brand new metal bearing, clean out the factory greese, and re-pack them with his own 'self approved' brand. within about 3 days, the seals would pop off (they are not designed to be pried of with a screwdriver, once you do, they are never the same) and 2/3 of the greese would leak out. Those disnt have any premature failure either.

                            Also when pulling a pit I check and replace the rear roller bracket half moon rubber cover support
                            .
                            We all know that when this wears away the roller will pull through the side of the machine and a new bracket will have to be bolted on! Great fun. Nae.
