You cant have grinding going into reverse unless your transmission mainshaft is spinning.
With the clutch fully depressed the mainshaft should be completely at rest, unless you are rolling. The only way you can spin the mainshaft with the clutch fully depressed is if the clutch disk doesn’t completely disengage from the flywheel and pressure plate it is sandwiched between.Splashonda, Bell housing misalignment isn’t caused by an accident. It is caused by core shift in the block,or a badly machined bell housing for example. It’s also possible the dowel pins that hold the two parts in alignment are missing. If someone caught something in between the block and bell housing during assembly,that would also cause it. If the crank shaft isn’t in line with the transmission input shaft you have problems.

You may have an issue with bell housing alignment. If the transmission isn’t concentric to the transmission you can have these problems. If your bell housing is removable you can check it with a dial indicator attached to your flywheel, sweeping the transmission bore. A good indication of these parts out of spec, is the pilot bearing and transmission input shaft tip being trashed. If you search “dial in a bell housing ” on you tube, you can get more detailed information. Misalignment causes hard shifts because flexing the input shaft changes the position of the main shaft. This affects the clearances of the syncros. At rest the shifts are fine,running with the input shaft moving in an arch,not so much. It also affects your clutch because the disk is on the input shaft that is being moved in an arch. I corrected a chevy truck with similar symptoms that was out .020″ from the factory.

Hey Eric, The place I work has forklifts driving themselves. They pull pallets right off the pallatizers and load them right into trailers. They also can stack them in storage
locations if there is no order right then. There are numerous problems with the system. Robot forklifts can’t tell if a load is unstable and about to fall. They can’t make the judgments that a human can. The result is lots of tipped over and crushed pallets. They also travel at a much slower rate. But they don’t take breaks or need benefits, so they are here to stay. I guess my point is we aren’t there yet, but it’s probably on the way. My experience with these units has made me more aware of how many small decisions and judgments a driver makes, without even concentrating on driving.Hey Eric, The place I work has forklifts driving themselves.

It really isn’t that bad. It goes without saying keep everything clean. I usually grab a clean piece of cardboard to reassemble on. There are some special seals in the kit that need to be soaked in hot water before installing them. There is also a ball screw that looks intimidating at first. You just remove the ball return track to load the balls back in. The rack and pinion are wedge shaped to allow you to set backlash. There is also a small torsion bar in the input shaft section. That is what actuates the valve. Make sure it isn’t broken. They spiral crack sometimes. Here in the rust belt the pitman shaft rusts and pits right at the seal lip. That trashes the new seal quickly if you just put in a new seal. We take our shafts to a machine shop next door. They turn that section down removing the damage. That does make the shaft undersize slightly, but it has never affected the sealing.

Hey aknight, I have replaced a couple harnesses and it was no big deal. The connectors are made so they only go to one place. Take your time and you will be surprised how easy it is. The ones that go to the tranny are the same as the engine they only plug into one spot. The only tricky part is getting the connectors to unplug. They have all different retaining methods.

Hey Eric, great tip on crunching the brake line nut a little, to get it loose from the line. I’m going to have to try that. I have had some really rust stuck ones this may have helped on. On the wheel cylinder mounting bolts, I have used a punch against the wheel cylinder (from the shoe side) to break the casting. The casting is thin in the bolt mounting area. They crack right apart in 2 good hits. Your replacing it anyway, and you can reuse the bolts.

Hey Havoc, We used Jasper for several years at the Wheelchair van/taxi garage I work at.
The vehicles we run are on the road all day long, under severe service. I would say the Jasper stuff holds up well. We buy mostly AC Delco units now because we get a better price. They hold up well also. The only problem I can remember with Jasper was a Ford 351 that came with a 302 cam. When we couldn’t get it to run right we called the 800 number. Amazingly a knowledgeable person answered the phone! He came up with the idea of switching the firing order to make it run. He told us it was possible the two cams were mixed up during the rebuild. He said the guy doing the test run may have used the 302 firing order to dyno it. He also got another engine on the way to us from his warehouse in Buffalo that arrived the next day. Even though it was a screw up, they handled it. They focused on solving our problem. I was on vacation the next week, but I think in the end, we ended up using the engine they sent us originally. It was in a money making van, and the whole front would have had to come back off to change it again. My point is they stand behind their product and have excellent costumer service. They aren’t cheap though.Hey Havoc, We used Jasper for several years at the Wheelchair van/taxi garage I work at.
