You can not any old bolt, if it snaps you will have another problem. The bolt needs to be high tensile and that is why a car wheel bolt is ideal 63

Not sure whether to bother with any spacers at all... Once the OEM ones are squeezed in they are 40mm. At 25mm the top of the shock will float horizontally 68

What is the rotor thread for removal, m16 x 1.5? That size is correct. Looks for a car wheel nut at that size, thread it in by hand attach a impact gun and it is off 70

On a lot of my CB750 oil pump builds, i would have to replace with new gerotors. Not a cheap rebuild.
Worked at Willesden engineering, rebuilding fleet Vauxhall and Ford engines which was so much easier and you were expected to do at least 12 units a day; Crank reground with oversize shells, rebored with new pistons, new valve guides, valve seats, valves, new cam shafts and all new rocker components, new core plugs, gaskets and seals,, new oil pump, new oil pump and so on. Which was cheap 71

A lot of small Honda's never even had a oil filter.

CB500/550 / Re: Kick start spindle« on: September 06, 2023, 07:13:27 PM »All done and working thanks. Not an easy job doing it from underneath the bike on the side stand. I had to use a piece of fishing line to hold all the parts on as they just wanted to slide off the shaft! I then fitted the circlip and pulled the line out once done. Thanks again It is a tricky job but, doable. Well done 75

A lot of the spin on types come with the tool these days. A lot of manufactures have a toque setting now because of the high pressure oil pumps.
The main Land rover dealer near me employed a guy in his mid 50's to be a service technician. After a couple of weeks of him working, they had a number of Range rovers and Land rovers returned with blown engines or massive leaks. He was putting the oil filters on and doing them up hand tight ( as he has always done ) The o'ring had been blown out due to the oil pressure |
