I need to rebuild my rear diff on a T2 009. I have new diff balls but do I need to replace the thrust bearing as well. The xray one costs £16 here in the uk which is very expensive if you have to replace it with every rebuild. Is there an alternative thrust bearing available in the UK for a sensible price. |

Hi i would suggest depending on how old the bearing is or if there is the slightest sign of wear that you change it when you do a rebuild. Here is a link to where i get my bearings from you will be amazed at the price of them i was( http://www.rcbearings.co.uk/index.php?m ... 7e27e99895) |

When i seen the price of the bearings from RC Bearings could not understand how Xray could justify the price of their bearings. If people are a bit warey about the quality of the bearings because of their price i have been useing frust bearings from them in my NT1 Touring car for a while now and have had no problems with them at all. Just remember just like any thrust bearing they need to be lubricated regularly otherwise the will not last. |

![]() I have big problems with my whole drivetrain. after 25-28 runsin the past , today i want to run again, but the car was only able to drive 2 chicanes and on the straight it lost power, feeling like an open diff. 1) some colleagues said, it is the rotor from my brushless - i usean other motor -some problem ![]() 2) some colleagues said,it is the main layshaft and the pulleys,- i check this, but can´t see any error. ![]() 3) one guy said, that there is a pending problem with the trustbearing of the diffs. so i disassemble the whole diff, and what i can see is, that the diff balls are very loose in the spur gear (looking as they are too small!!) , and the cone washers were a little bit flat and not so strenght after the rebuilting of the diff without a spare part i set it very,very tighten and try to run again. AFTER 2 CURVES THE SAME ISSUE AS ABOVE; LOOSE DRIVE TRAIN !!!!! ![]() we hold down the front tires and the rear tires and try to rotate the spur gear. there is a small "click" and the spur gear jumps a small unit, but where ???? WHAT IS GOING ON HERE I AM VERY;VERY ANGRY ![]() AFTER 27 years of making this hobby I m on the end .... after 4.5h of rebulilding, checking I have NO IDEA ![]() regard sad harry in vienna still have no idea what i have to buy to get in shape with my T3, whatI bought 2 weeks before. |

I hope XRAYwill develop a gear diff in the future. Tamyia have this already done for their Worldchampion.

hello, I drove a Robitronic 5.5T (84/23) -hot weather with nosram cooling fan) and a Rob. 7.5T (84/24), was happy on wednesday and on friday I only change from a Robitronic ESC to a SP GT2 ESC and assemble the new ECS shafts in the front . on saturday after 3 fast chicanes on the straight the cars was going slower and slower. i recongnize on the left side(ECS) that the ECS shaft was not able to run exaclty due the fact the loctite was to much and "blocks"the whole functionality - i change to a steel one. but there is still a drive train problem as I describe it above . - and I´m not able to find it - I´m sad about it |

Harry Have a close look at the diff again after you get the problem - is it slipping if you hold one wheel and the spur gear? If so, it may be loosening itself if the thrust washer is binding - putting a loosening torque on the screw during cornering. Never had this problem myself, but worth looking at. I can also confirm that the rcbearing products are great, I have had no problems at all. Note that if you get thrust bearings from a 3rd party, get one with the grooves in the thrust races for the balls - it has a higher load rating than the flat races of the xray product. (The ones from rcbearings are like this). I use the Xray graphite grease on the thrust bearing and thicker silicon grease on the balls/plates of the diff. I think the xray silicon grease is a bit thin..... Charles |

hey, .........some time is gone to think about many parameters, which were done or were not done from my side. I trust, that the thrust bearing is greased out of the box, as it was in the past so. -- my fault And of course, I really do not take much attention to break in the diff correctly. --my fault -- I´m spoiled with the touring cars from 2003 time we drove, as we build up a diff and drive 1 year and more...... so tomorrow I will get new part, cone wahsers trust bearing diff plates , diff balls, etc. I will rebuild the diff again with these new parts and then we will see what will happen on Friday...... so please, wish me the best..... I trust in XRAY´s development competence.............. ![]() since the first kit T1 2001 (with setup tools, and screw drivers) ![]() best regards Harald |

Dear all,, I have to apologize. ![]() it is/was NO mechanical error - - no thrust bearing, no diff balls etc..... it is/was a NON-compatibility between Robitronic motor and SP Gt2 ESC. if the motor runs warm (at 60 Deg . Celsius),the motor is sending something to the ESC and the ESC doesn´t work correct or goes in sensoreless mode.- and this error has a sound like a open diff. - the ESC is not able to "pump" the electrical timing on the motor - the motor is doing like a pig "queeek" this problem appears also at LRP SXX stock spec ESC with other 13,5T Robitronic motors. - if they are "over-timed" (setting over 4 degrees on the motor) today it was very hot here in vienna about 34 deg celsius - so everybody has to reduce their boost and supercharging levels on their ESC´s. So, I´m very sorry, that I suspect the team xray or my dealer Roman Stopka.....that they make mistakes...or were not well informed of something or they playing with weak parts the only thing what I can summarize is, that I have learned a lot of "special" issues of Rc-racing today!! ![]() eg. ESC setup - motor temp - boost levels, gearing etc.... thank you to everybody, who tried to help me.. sorry that you have a lot of inconvenience with me regards harald vienna |
