Corrected Code
USE THIS
public with sharing class MaintenanceRequestHelper {
public static void updateWorkOrders() {
List newCaseList = new List();
Integer avgAmount=10000;

List newEMI = new List();
List caseList = [SELECT id,Vehicle__c,Subject,ProductID,Product__c, (SELECT id from Equipment_Maintenance_Items__r) from case where status='closed' and Type IN ('Repair', 'Routine Maintenance') and ID IN :Trigger.new LIMIT 200];
Map equip = new map([Select ID, Equipment__c, Quantity__c,Equipment__r.id,Equipment__r.Maintenance_Cycle__c from Equipment_Maintenance_Item__c ]);
for(case c: caseList){
case newCase = new Case();
newCase.Type = 'Routine Maintenance';
newCase.Status = 'New';
newCase.Vehicle__c = c.Vehicle__c;
newCase.Subject = String.isBlank(c.Subject) ? 'Routine Maintenance Request' : c.Subject;
newCase.Date_Reported__c = Date.today();
newCase.ProductId = c.ProductId;
newCase.Product__c = c.Product__c;
newCase.parentID = c.Id;


for(Equipment_Maintenance_Item__c emi : c.Equipment_Maintenance_Items__r ){
avgAmount = Math.min(avgAmount,Integer.valueOf(equip.get(emi.id).Equipment__r.Maintenance_Cycle__c));
newEMI.add(new Equipment_Maintenance_Item__c(
Equipment__c = equip.get(emi.id).Equipment__c,
Maintenance_Request__c = c.id,
Quantity__c = equip.get(emi.id).Quantity__c));
}
Date dueDate = date.TODAY().adddays(avgAmount);
newCase.Date_Due__c =dueDate;
newCaseList.add(newCase);

}
if(newCaseList.size()>0){
Database.insert(newCaseList);
}

for(Case c2: newCaseList){
for(Equipment_Maintenance_Item__c emi2 : newEmi){
if(c2.parentID == emi2.Maintenance_Request__c){
emi2.Maintenance_Request__c = c2.id;
}
}
}
