How do I insert cable into my Shimano XT SL-M740 3 Speed Rapid Fire Shifter

I finished changing the cable of Shimano Deore XT SL-M740. Unfortunately it did not have the plastic screw hiding the chunk of lead at the end of the cable. I mean that there is no hole from which the cable can be pulled out. Therefore, I removed the front panel where you see "Simano Deore", but this panel only removed the shift position indicator and the internal mechanism was covered by another metal sheet. To change the cable I had to remove the small cover between the barrel adjuster and the lever. The cover is fastened by two very small screws. An encouraging sign was that one of these screws was missing. That indicated that a previous owner had removed the cover once. The cable end was attached to a component exactly like a brake cable is attached to a brake lever. This component pulls the cable around the shifter. The sift cable is not attached to the shift lever. The sift lever rotates the said component. The barrel adjuster had a slot to put the cable inside. Therefore, attaching the cable to the above component was easy. When the cover was installed, I attached the small screw to the end of a driver with silicon paste. Someone suggested to use grease, but grease is messy.

Best shimano rear drailuer for a shimano 11-46t cassette?

There is no "best" derailleur for any particular situation. Get one rated to handle the range, at a price you can afford, and that has good reviews. Performance is more affected by how well you set up derailleur and cables, as well as chain and condition of cassette, than by individual model differences.

I have Shimano 105 flight

Could actually be both. Squirt a small amount of lubricant between the two paddles and shift one or the other multiple times to see if they free up. If not you made to take it to your local shop where the can disassemble the shifter to see if debris has lodged itself inside.

I have a 18 speed malvern star bike with shimano gearing and i need to know how to the path for the chain

The only reason I can think of for needing that info is a broken or replacement chain. In either case one needs the proper tool and connecting link to size and install the chain. Do not do so without knowing the proper procedure. Find a bike co-op or bike shop locally to help, or a knowledgeable friend, or Google "install bike chain".

When readjusting the cable tension the screw that holds the cable tight on the back derailer got dislodged and fell out of the housing. Some how the derailer body moved and the screw cant go back in.

Derailleur position should have nothing to do with being able to reinsert the cable binding bolt, and unless the cable is very loose the tension is adjusted with the barrel adjuster at the end of the cable housing.

Ho remove freehub on shimano fh-rm30

The free hub body can be removed from the hub after the axle and bearings are removed. Typically you use a #8 Allen wrench. It will be tight and will take some effort, righty tighty-lefty loosy.

I have a loose Shimano 105 8500 shifter blade. How do I tighten them?

I'm not sure what you mean by "shifter blade", but I might assume it might be the cage of the derailleur. On the front derailleur there is either a rivet or a small bolt at the trailing edge that holds the two halves together, if it is a rivet then it is not repairable and the derailleur will need to be replaced, if it is the bolt, it is probably a 8mm socket head, tighten to the right. If it keeps loosening up from road vibration then the threads could be stripped (replace the derailleur), or else put a drop of Blue Loctite on the threads to prevent it from backing out. If you are talking about the rear derailleur cage that holds the two pulleys in place, these have two Allen type bolts, probably 3mm or 4mm Allen wrench size. The bolt slides through a small bushing inside the plastic pulley wheel, the bushing is slightly wider then the pulley to prevent over tightening the cage plates against the pulley, thus preventing the pulley from spinning freely, use the Blue Loctite if the bolts keep coming loose. Blue Loctite (also known as 242 Loctite I believe) is the removable type and provides some extra friction to prevent bolts from backing out. Now if by "shifter blade" you are referring to the shift/brake levers, these have a small amount of "play" in them from the factory, a little bit of wiggle. They basically are not serviceable. Try adjusting the derailleur cable to see if that removes excess play. If they still have an excessive amount of play in them, then you will need to replace the shift/brake levers as a unit. If you do this, make sure you get the shifter that is designed for the number of cogs you have in your gear cluster and front chain rings. I would recommend also replacing your chain and rear cluster at the same time so that all part wear evenly for optimal shifting performance.

I have a 2001 Specialized StumpJumper FSR XC and have put a new chain wheel on 48t and I'm struggling to find a front deriailleur that fits any help please?

Clamp on front mech xt or xtr would be an option, be careful if you need bottom pull or top, cut or grind off bracket on old front mech to reinstall,as this is a spacer as well as a mounting bracket ,bit old school but older front mechs are best

I have a Peugeot bike vintage 1985. I want to replace the rear derailluer with a new style. What model shimano rear derailleur should I buy and do I also have to buy shimano shifters

If you have friction shifting you can replace with any derailleur that will handle the freewheel/cassette range. If you have indexed shifting it depends on what is on the rear now. I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881
