August 11, 200917 yr I was refitting the forks on my 99 model txt270 and i thought i'd grease up the head bearings and that, been as forks were already off. i noticed the bearings were a bit sh*ty. just wondering if anyone new the part numbers of the head bearings i need for my bike. i know they sell them on fleabay but i'v got hundreds of bearings in work so i just need the part numbers and i can cross reference them then.
August 11, 200917 yr Gday, If you can measure the ID and OD and width's I can cross reference them in my book and give you a number/s. Cheers, Stork
August 12, 200917 yr Author Ok I'l try and measure them, to be honest i was hoping some one would know the part numbers cos i've built the front end of the bike back and didnt really want to take it back apart until i had the new bearings. is there any other info u'd need cos the bottom head bearing is a tapered bearing????/
August 12, 200917 yr If it is the same bearings as the Pro uses (why not?) I think I have one lying around. I`ll check the numbers when back from work. Both the upper and lower bearing are tapered BTW... -Jan
August 13, 200917 yr Hi scotty, These are not the same as the PRO head stock bearings, they are taper roller but a smaller size than the PRO. Look for an equivalent to HIC LM117 49/10. Pack with a water proof grease like Mobil HP or similar. Bye, PeterB.
August 13, 200917 yr Author OK Cheers peterB, r the upper and lower steering bearing exactly the same??????
August 20, 200917 yr Author Hi Pete I cross referenced that part number and found some bearings Dimensions are Internal 17.462mm External 39.878mm and width 13.843mm Does this sound right???? the shaft seemed bigger than 17mm but i cant really remember.
August 21, 200917 yr Hi scotty, Here I am! Your cross references are fine, I just measured up an old brg with a vernier to get nominal sizes 17x40x14. Bye, PeterB.
