Hi legends,
Regards from Stage 4 lockdown in Melbourne.
I pulled the injectors from a 1HDT last week and used the well documented reverse clamp method to extract the injectors. For all but one the copper washer was attached and came out along with the injector. However, the washer on #5 was stubborn as anything and did not budge.
After 3 days of letting it soak in CRC and gently trying to pull it out with a thread tap it was still not enough to get a pick under the washer. As a last resort some screw driver and chisel work got the copper washer came out. Unfortunately this was not my best work and with some frustration this process has damaged the injector seat.
I am aware that the copper washer must be 0.136" thick and the depth of the injector nozzle once seated is critical to the smooth running of the 1HDT. My question is what is considered 1) the best, 2) most cost effective and 3) least intrusive way to clean/ream this injector seat to ensure the copper washer or a combination continues to make the seal around the injector.
The reconditioned injectors are due to arrive in a few days. The POA was to install the reconditioned injectors with new washers and monitor it closely for any leaks. However this will probably not sit right with me in the long run and addressing the damaged seat is something i would prefer to do anyway before it leaves me stranded or has compounding adverse effects to the reliability or functionality of the injector/motor.
Happy to take all feedback and criticism on board, so that others who may run into similar dramas in the future may find this thread useful.
Cheers
