repair of loose thread in cylinder head

[spyghost]

Hi,

Meron bang available dito sa atin sa pinas ng thread repair kit ng loose thread para sa aluminum cylinder head? I'm thinking of repairing a loose thread hole instead of purchasing a surplus head or brand new head.

Thanks

Convert it to stud. A stud has two threaded sides. Baon mo one side and put locktite para permanent then put a nut on the other side to fasten what ever needs to be fasten and torque it as specified. I did it on a 4d56 camshaft cap before in school, natuwa and teacher ko sa ginawa ko. I hope it can apply to your problem. Goodluck!

you can use re-threading kit but you will use a bigger size of bolt since you will re-thread that portion.. you can buy that in any hardware store or stores that specializes in bolts and nuts..

meron bang option na same thread size ang gagamitin? yun bang magkabila meron thread ang ibabaon?

parang ganito, lalakihan ang butas ng loose thread na butas, tapos me ipapasok na larger screw, pero ang screw na ito e meron thread sa gitna na fit sa dating bolt size?

bro, Puwede mong ipa- over size ang thread at palitan ng syempre mas malaking screw or ipa -re build up mo na lang at saka lagyan ulit ng thread na same as original, alam ng mga nasa machine shop yan tanong mo na lang sa kanila, kaysa mag palit ka pa at makaka tipid ka, not unless malaki na ang damage nyan....good luck
