Anytime I recognize a customer's name on the caller ID or a vehicle rolling down the driveway, I'm like oh god what did we screw up. Most the time it's like "hey y'all did a transmission for us a while back, it's still doing great, I got another one though!".

A tip I recently learned: To measure a step with a caliper, use the opposite side of the caliper from the depth gauge bar. (Use the top flat side of the fixed jaw, and the top flat side of the movable jaw for a clean step measurement.) Now I only use the depth gauge for small bores like a blind hole. Edit: I’m aware you have far more experience than me and may not be using this step measuring surfaces for a reason, but others may find this knowledge useful

@kellyappel3015 Жыл бұрын

Can't say I've ever noticed a sharp edge on the flywheel due to machining, so maybe other shops do it too. Either way, the extra step of chamfering IS appreciated. When removing a broken bolt (flush or recessed), ALWAYS weld the flat washer first, and drilling the bolt a bit also helps. Welding the nut and washer in one step reduces the amount of penetration you'll get into the bolt. Have heard of horror stories decades ago where machinists weren't aware of the specified heights on the multi disc clutches. Yep, slippage occurs right away.

I've done a few of that style flywheel over the years. Always took the drive dogs out or intermediate plate guides (whatever you want to call them) out so you dont ruin the grinding stone and the new surface goes right to the outside edge. There is a special tool too then reinstall the guides square to the new surface so the intermediate plate doesn't hang up.

@dangerrangerlstc Жыл бұрын

I think the chamfer on the inside is a bit necessary since the inside corner of the machined mating surface of the clutch housing often has a very small radius. Putting the small chamfer gives clearance for the radius. We have a similar flywheel grinder in our truck shop. It's one of the more abused tools we have. People often feed too hard and break the grinding stone

@SR-yp3eg Жыл бұрын

If I remember correctly the van Norman grinder I used a while back had a adjustable bar on the turret that would except carbide lathe type tooling to correct the radius post grinding so as not to damage the CBN cup wheel

@wackowacko8931 Жыл бұрын

The manufacturer usually provides a minimum thickness that the flywheel can be machined before causing an unsafe product. Brake drums used to have their minimum thickness cast into the drum so that they couldn't be machined further than a maximum distance, some other cast parts have this as well, but not typically flywheels for the most part. You usually have to look those up.

@SLeslie Жыл бұрын

That yellowish-white powder on the nut after welding is zinc oxide and it is not particularly helalthy. It would be better to use non-galvanized hardware to welding to.
