I assume you're talking about the starter jackshaft. I'd suspect that there is a misalignment between the starter and the bushing in the outer primary. I'm reluctant to say this but you may have to pull the dowel pins out of the inner primary that are supposed to align the outer primary up with the inner. I've heard of them being improperly placed causing this misalignment.

Now, if for some reason you have the inner primary off, you may can bolt the inner and outer together without the starter on the inner and take it to a machine shop to have the alignment checked. I've never done this but I had one checked once. The machinist cuts a bar or tube that fits the jackshaft support bearing in the outer primary. It's long enough to protude up through the starter hole in the inner primary. With this, he checked the alignment of the primary covers. You may can just use the jack shaft to check it with, I have never tried that. I've done one like this but I can't say that I fixed it because the guy has not come back with another broken jackshaft. I think he would if he broke another one.

Good luck

I have an 88 ford bronco 2 v6 automatic 2wd. I replaced The flywheel twice because it kept breaking. Someone told me I should get a new torque converter that a faulty one could be causing the flywheel...

Two major possible causes here:
1. Your starter is not engaging the teeth on the outside of the plate properly, as shown by chewed-up teeth, both on flywheel [actually called a flexplate on automatic], and on starter. Dirt trapped in between the starter and the housing will keep it from mating properly, and cost you big bucks. Shims are available to get the teeth exactly lined up.
2. OR your torque converter is indeed not true to the engine drive-shaft, causing pressure off-center. That would cause the flexplate to break out at the center. If this is how your plates broke, you probably will need a new automatic transmission.
If you also have engine oil back there, the rear bearing of the engine could be shot, indicating bad things. Have a pro check both shafts for sloppy bearings.

I have a proline 1.5hp pump need to replace the shaft seal. I can't seem to get the plastic impeller off. We use a screwdriver to hold the shaft screw and try to turn the impeller counter clockwise...

Keep trying - It is stuck and will likely break but you have to remove it to change the seal. It is not uncommon to need to replace the impeller when the seal fails since the water gets behind the impeller shaft and rusts the metal causing the impeller to bind. If you still cannot get it free pull the motor thru-bolts and lock the rotor once removed from the motor in a vice. Use a large pair of channel locks to break the impeller free...replace it if necessary.

Lost reverse in my 1995 GMC Yukon 4wd. Other gears are working. Is my tranny shot or is it something else?

Usually when you loose reverse in this transmission it it because the reaction shell strips or breaks do to high line pressure caused by a P01870 code being pressent.Another common cause is the needle bearing on the input drum/shaft breaks up and the pieces get lodged in the reverse input drum and keep those clutches from applying.Long and short is there is no simple fix,adjustment,or sensor that will keep you from having reverse.It is time for major transmission repair.Let me know if I can help in anyway.Thanks David@FIXYA

I have a 1997 onan emerald series GenSet 6500 I have been thru 4 starters it keeps breaking the drive gear assmbly WHAT CAN I DO PLEASE ITS ALREADY COST ME 400.00

Have you replaced the solinoid too? If not, maybe the solinoid is staying engaged, which keeps your starter, well starting. If the starter stays energised the flywheel WILL tear up the starter gear.

hope this helps

I have replaced the cv shaft twice and it keeps breaking down! whats the most probable cause for this?

Try checking the transmission mount. A bad mount causes the transmission to move back and forth too much, causing unnecessary strain on the axle shaft. Also make the shaft is the right length. Too long or too short can also cause the shaft to break.

My 2001 kx250 keeps breaking kick shafts after 15 or 20 kicks. i've replaced the spring, bushing, circlips, washers and now two kick shafts.

i am not as familiar with kawaski's but a friend told me that certain kx's and yz's had poor quality shafts that were brittle?

the couple of broken shafts that i've seen were caused by the kicker being kicked so aggressively that when it contacts the stop. the stop acts as a fulcrum transferring the load to the shaft thus breaking it and possibly the case to.

Why does the belt keep breaking as soon as I turn on the vacuum?

Hi Have you got the correct belt? If its breaking then the brush end caps or something is clogged. If you can get into the floor head ensure you look at the actual brush roll to see if there is anything is clogged or trapped. Remove all matter of dust and see if that works.
